3 point assurance guide for the best solar companies in Perth

Derek McKercher being interviewed by Markus Lambert from Your Energy Answers (Dec 2025) regarding how PSW ranks as one of the best solar companies in Perth for 2026

As time passes, it becomes increasingly clear which solar companies in Perth stand out as the best. The industry has matured, making business listings valuable research tools and a valuable key indicator of past customer satisfaction for established companies. In contrast, newer companies may have outstanding review profiles due to a short history of installations, limited market exposure, and reduced aftercare commitments.

In 2026, consider evaluating the top solar companies in Perth using a measurable three-way gauge discerning service and product assurance over time:

Certification x Satisfaction x Business History = Assurance

Local guide: Perth Solar Warehouse ranks as one of the best solar companies in Perth (Top 3), Western Australia, according to SolarQuotes.com.au (Reference: Western Australia’s Best-Rated Solar Installers 2024,25)

Industry observations indicate that most customers prioritise how leading solar companies in Perth adapt to and support their clients over time, rather than simply focusing on sales volume. To refine this assessment, it’s helpful to prioritise local solar companies that show a strong commitment to aftercare. 

Organisations with a proven track record that aligns with NETCC endorsement and international business standards, such as ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety), are more likely to provide high-quality solutions over an extended period.

Solid differentiators

Identifying the best solar companies in Perth can be a subjective process. If the criteria focus solely on installation volume, it may not accurately reflect how a company treats its customers in terms of aftercare and support over 8 or 12 years. Many companies achieve high installation figures by simultaneously completing multiple large jobs in a short period, which may not necessarily represent customer satisfaction or long-term service quality.

1.

1.1) Business certification to an internationally recognised standard. A leading company has the opportunity to establish effective business management within an audited framework. While the process may be comprehensive, it’s essential to understand that with sustainable energy now being a mature industry, ISO certification helps distinguish quality-oriented solar companies from mere marketing claims. Look for: ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety Management).

1.2) NETCC certification to an ACCC-endorsed benchmark assisting customer protection standards. The New Energy Technology Code of Conduct is an annually reviewed guideline that most of the best solar companies in Australia adopt to aid product conformity and transparency in a purchase. Look for: The blue circle, New Energy Technology Approved Seller Logo.

2.

2.1) Diverse satisfaction. The internet offers a wide range of review platforms, and many solar companies channel energy into one or two targeted third-party sites. In contrast, lesser-known review platforms provide alternative perspectives. Observing a basic search, balance, or variation offers a more comprehensive understanding of the best solar companies in Perth, away from the noise. Look for: Inconsistencies comparing various platforms.

2.2) Volume of satisfaction [alone] should be a lesser guide in 2026. A significant margin will disproportionately represent marketers versus business owners/operators. Diverse platform satisfaction now reigns supreme, enabling a more accurate cross-platform comparison of a solar company’s reviews. Consider: Greater than +200 combined reviews over various mixed volume platforms.

3.

3) Time in business is a superior measurement in solar company refinement. Most manufacturer warranties are 10 years or longer in duration. Ensuring a local point of contact with defined aftercare is essential in a mature industry. Today, investing in energy products is only as good as the business that installs them. Enhance your return on investment with a proven power supply partner, recognised for its longevity and dependable business practices. Further refine selection, honing in on a company whose guarantee complements its operational history. Highly value: 10+ years

4.

Extra assurance:

4.1) Local roots. WA’s homegrown organisations are hands down the best solar companies in Perth. Local business gets you! It understands related ongoing needs and can better assist at times of support. A solar company’s operating hours aligned with Western Australia’s timezone improves operational assurance. Look for: a homegrown journey on the ‘About’ page of the company website.

4.2) In-house serviceability options provide customers with the level of time-based standardisation and system execution assurance they desire. A close-knit solar installation/service company with high-quality subcontract and in-house installation delivery will likely receive regular product care training due to an over-riding Electrical Contractor licence. Strongly consider: Solar companies with a West Australian Electrical Contractors (EC) licence number.

4.4) Physical commercial presence is one of the strongest indicators of a solar company’s commitment to the local region. Strongly reconsider: Solar companies with city office listings.

4.5) Cybersecurity and data privacy considerations are a vital indicator of an organisation’s commitment to value-defining aftercare beyond general support. It is imperative to evaluate the security measures in place to prevent unauthorised access to your home’s data by temporary staff.  Highly value: Cybersecurity and Personal Data Management Policies in 2026.

Physical commercial presence remains one of the strongest indicators of a solar company’s commitment to the local region. 

Best third-party measurement tools

Specifically, three well-known review platforms for solar companies in Perth are Google, SolarQuotes, and SolarChoice. While other options, such as ProductReview and TrustPilot, exist, it’s essential to recognise that these international platforms primarily serve organisational marketing purposes, offering enhanced listing benefits for a fee. Below are reputable platforms that, in our opinion, do not engage in review gating or where customers can gauge genuine business insight. 

Google is accessible to everyone. It’s an excellent tool for companies to stay vigilant about all interactions, even those from non-purchasing customers. Reassess: low review counts compared to company size/short earliest review timelines.

SolarQuotes.com.au is a controversial platform because it offers paid features for approved installers. Consequently, solar companies that receive leads from SolarQuotes often have a higher number of reviews than those that do not. One advantage of the reviews on SolarQuotes is that they follow up with verified customers, ensuring the authenticity of the feedback. These reviews are useful for customers trying to evaluate various aspects of an installer’s qualities. Most of the top solar companies in Perth are measured on this site, including those that are not subscribers.

SolarChoice.com.au is comparable to the SolarQuotes platform in terms of credible installer referrals (you’ll likely find a good one here). The installer review section is more recent, meaning the reviews for many of Perth’s currently recognised top-rated solar companies are lower in volume than on alternative platforms, which may lead to a more likely deviation. SolarChoice.com.au offers customers credible and free information throughout the research and support phases of their sustainable energy journey.

Forget Facebook reviews. Facebook’s most discerning feature is the business timeline! Are they a local community hero or a marketing outlet with limited long-term substance? Facebook provides a community-focused pulse of every business in 2026. Avoid: Marketing walls with no personal identity. Look for: Real humans (the people behind the brand).

Social presence and depth distinguish solar companies. Select a company with which you feel comfortable returning for operational queries and aftercare.

Customer experience x time

While there appears to be a multitude of solar companies competing for your project, only a select few will disclose their establishment. Establishment adds value to every warranty.

Its proven product warranties are only as good as the installation company behind it. Consider a 1-year company with a 10-year guarantee (1/10) vs a 10-year company with a 10-year guarantee (10/10). 

Experiences hold significant value when measured over time. A series of positive experiences in a short period can lessen the importance of customer reviews for those who prioritise aftercare and ongoing satisfaction. Further enforcing this perspective are AI business overviews. In 2026, the focus has shifted from the quantity of reviews to their depth and diversity. 

Strongly consider: Refining your shortlist of leading solar companies in Perth through individual research. Focus on platforms with low review counts (third-party websites with fewer than 50 reviews). Low-review platforms provide an enhanced cross-section for comparing the top solar companies in Perth. Heck, it’s the AI era. Prompt your ideal refinement criteria into your preferred AI search, including any specific requirements you have for a home energy system (enable extended thinking).

Manufacturer allignment

Manufacturers count on reliable local solar companies to implement their products on-site, regardless of an individual’s credentials. SAA-accredited installers may not always remain affiliated with a single business for the entire duration of your warranty or support needs.

As a result, manufacturers endorse trusted partners to assist with their products. The best solar companies typically specialise in the product suite they work with, ensuring they are well-versed in specific installation practices. Manufacturer-certified installation businesses are often committed to product-specific, continuous professional development.

Industry recognition

There are many recognition systems in 2026 (awards/badges that many companies showcase). While peer review recognition is beneficial, it should rarely be a determining factor in a company’s shortlist for product consideration. You’re searching for the right fit, and not everyone’s a cowboy. Sustainable energy adoption is a worthy choice with a credible installer.

Award mechanisms can add weight when splitting hairs and are typically composed of aspects that fall short of the above criteria combined. A limited lens, these systems are fundamentally based on participation, excluding many reputable solar installation companies in Perth.

Nevertheless, participating solar companies have earned their peer-reviewed endeavours. Look for: Sunwiz, SolarQuotes, SolarNerds, Smart Energy Council, Clean Energy Council or leading manufacturing brand recognition.

  • SolarQuotes.com.au: Legendary-rated 2023,24,25
  • Sunwiz Award: Top 10 Combined [Residential & Commercial] WA 2024,25
  • Sunwiz Award: Best Rated Solar Installer (Australia) 2023,24,25
  • Sunwiz Award: #1 Local Solar Hero (Perth, South West) 2025
  • Solaris Award: Top 5 Solar, Top 2 Battery (WA) 2025
  • EUPD Research Top Brand PV Installer (Australia)
  • Tesla Performance Excellence Award, Q4, 2023
  • Sigenergy international recognition, Intersolar Germany 2025

Take them with a pinch of salt.

When considering 95% of solar companies Australia-wide, there’s now a mature industry formula for improved long-term product assurance: 

Certification x Satisfaction x Business History = Assurance

Guide: Sigenergy SigenStor, the reimagined home “energy hub”

Sigenergy SIGENSTOR render with with five in one key features listed: Solar Inverter, EV DC Charger, Battery PCS, Battery Pack, EMS

A good home battery in Perth is no longer just “kWh on a wall”. In 2026, battery value is mostly decided by (1) how well the system shifts energy away from Synergy’s expensive late-afternoon/evening period, (2) how cleanly it integrates backup power for outages, and (3) whether it can grow with your household—EV charging, added storage, bigger solar, or tariff optimisation.

Quick insight

  • Modular storage: 5.2kWh usable (5kWh class) or 7.8kWh usable (8kWh class) per module, using LFP chemistry.
  • Scales cleanly: the controller supports 1–6 battery modules, so you can stage capacity as budgets and usage change.
  • Backup power is an option, not a compromise: add the Sigen Gateway for whole-home or partial-home backup (site-dependent design).
  • EV integration is genuinely different: optional EV DC charging modules up to 12.5kW or 25kW, including bi-directional V2X capability (subject to EV compatibility and local rules).

Sigenergy’s SigenStor platform remains one of the more compelling “ecosystem” entrants because it was built as a modular, DC-coupled architecture from day one: an energy controller (hybrid inverter) plus stackable LFP battery modules, with optional gateway (backup) and EV DC charging.

Contents

A reimagined concept. Sigenergy SigenStor is transforming home energy management with a modular approach. Central to this system is the Sigen Energy Controller, a hybrid inverter that efficiently converts solar and battery DC power for household or grid use, featuring multiple MPPT inputs for optimal efficiency. Homeowners can customize their energy storage using stackable Sigen Battery modules available in 5.2kWh or 7.8kWh capacities.

Additional components like the Sigen Gateway provide blackout functionality and backup load control, ensuring continuous power during outages. For EV owners, the Sigen EV DC charging module offers fast charging and bi-directional V2X technology. This system allows for a tailored energy setup that can be easily expanded to meet growing needs, all without major renovations.

Which to consider?

Step 1 — Single-phase or three-phase power supply. Most Perth homes are single-phase; larger homes and businesses (big ducted AC, workshops, bigger EV loads) are more often three-phase. Your power supply affects controller selection, backup design, and the amount of instantaneous power the system can supply.

Step 2 — Choose the right foundation (controller power class). From a technical perspective, key controller attributes include PV voltage window, MPPT count, and conversion efficiency, as these influence design flexibility and yield over the long run. For example, the controller supports up to 4 MPPTs and high DC input voltage, which helps when Perth roofs have mixed orientations (east/west splits, partial shading, multiple strings).

Step 3 — Size battery capacity to your “after 3pm” usage. In WA, the economic problem batteries solve is the high cost of electricity in the late afternoon/evening. If most of your consumption happens after 3pm (cooking, AC, pool pumps, EV charging), storage value rises quickly.

A clean sizing rule for most WA households:

  • Scale in 8 kWh of Sigenstor battery modules for the best value per kWh of storage.

  • Balance-of-system costs (gateway, commissioning, switchboard work) don’t scale linearly.

SigenStor makes staged expansion straightforward because the controller supports 1–6 battery modules.

Backup power: what to expect

If blackout protection matters, design it explicitly. The Sigen Gateway is the enabling component for backup operation, and it supports whole-home or partial-home backup depending on site constraints and how circuits are configured. What this means:

  • “Whole-home backup” is achievable on some sites, but it’s not automatically smart (you still want to manage large loads like ducted AC).
  • “Essential loads backup” (lights, fridge, internet, selected socket outlets, some AC) is often the best value design.

EV charging and V2X

Sigen EV DC charging is one of the platform’s standout differentiators. The module supports up to 12.5kW or 25kW charging and discharging, CCS2 interface, wide operating voltage range, and IP66 protection. 

Two important caveats:

  • Bi-directional” is not just the charger. Your EV model must support the required V2X behaviour, and manufacturers publish compatibility lists that change over time.

  • Any export-to-grid behaviours can be subject to local network approvals and program rules. Treat V2X as a capability you plan for—not a guarantee you’ll use day one.

For most Perth homeowners today, the immediate benefit is simpler: faster solar-optimised EV charging that keeps more of your solar on-site instead of pushing it to the grid.

Warranty and long-term ownership

The Sigen Battery and Sigen Energy Controller are covered by a 10-year product warranty, while the EV DC charging module has a shorter warranty period of 3 years. The battery performance warranty includes details on energy retention and throughput.

Additionally, the warranty document emphasises the importance of connectivity, outlining expectations for internet connection and specifying the consequences if the system is disconnected for extended periods. Here’s what’s materially relevant in Sigenergy’s current warranty terms:

Covered Product

Sigen Battery
10 years
Sigen Energy Controller

Our position at PSW: we size and configure systems so you’re not “using the warranty” often. That means conservative switchboard integration, correct thermal placement, and commissioning discipline—not just selecting a brand.

WA rebates, VPPs, tariffs and ROI examples

WA incentives: meaningful in 2026. The WA Residential Battery Scheme is live and is explicitly structured around VPP participation. It states combined rebates (state + federal program) of around $5,000 for Synergy customers on a 10kWh battery (and higher for Horizon Power regions), plus eligibility for no-interest loans (income-tested) up to $10,00 over 10 years via Plenti qualification.

Joining a VPP can create additional value streams (for example, event credits). The VPP agreement is time-limited for an initial 2-year period, then an option to opt out (not a permanent lock-in). Lean more ›

Synergy pricing reality: the “battery window” is late afternoon/evening. On Synergy’s Midday Saver time-of-use plan (effective 1 July 2025 pricing), the peak period is 3pm–9pm with a materially higher usage charge than the super off-peak daytime window.

Illustrative payback mechanics (simplified). Example household: 20kWh/day, with ~10kWh occurring during 3pm–9pm (AC, cooking, pool, EV top-up).

If a battery reliably supplies 8–10kWh into the 3pm–9pm window, the value per kWh is roughly the peak import price avoided (less round-trip losses). On Midday Saver, that peak usage charge is 53.8446c/kWh.

Very rough annualised value for shifting 10kWh/day into peak avoidance:

  • 10kWh/day × $0.538 ≈ $5.38/day

  • ≈ $1,950/year before losses and seasonal variation (then discount for round-trip efficiency, weather, and behavioural reality)

This is why “battery ROI” in Perth is mostly a load-shape conversation. Two households can buy the same battery and see totally different economics depending on whether their usage is daytime-heavy or evening-heavy.

Important: don’t build your ROI model on best-case export assumptions. Batteries win primarily by reducing high-priced imports, not by selling energy back. Any VPP credit upside should be treated as a bonus layer—not the foundation.

Competitive landscape: Where Sigenergy fits

In 2026, Perth’s battery market broadly falls into four groups:

  1. Premium “single box” batteries with strong brand pull

  2. Modular HV/LV stacks paired to hybrid inverters (often very cost-effective per kWh)

  3. Ecosystem-first solutions (battery + monitoring + load control + EV integration)

  4. VPP-aligned offerings optimised for orchestration and grid services

SigenStor’s competitive edge in Perth is that it competes in (2) and (3) at the same time: it’s modular like the best stack systems, but it also offers an integrated pathway to backup and EV DC charging with V2X capability.

If you’re comparing SigenStor to alternatives, the three “apples with apples” checks we recommend are:

  • True usable kWh and staged expandability (not just nominal capacity).

  • Backup inclusion and backup design scope (whole-home vs essential loads).

  • EV roadmap: whether EV integration is bolt-on AC charging or genuinely integrated DC/V2X capable.

If you’re researching a Sigenergy SigenStor battery in Perth, the fastest way to get an accurate answer is a structured assessment:

1. Confirm phase (single vs three-phase) and switchboard constraints

2. Pull interval data (or bill + usage pattern) to quantify your 3pm–9pm demand window

3. Decide whether backup (if required) is essential loads or whole-home

4. Size the first-stage battery (and map your expansion path)

5. Validate eligibility pathways if you’re targeting WA rebates/VPP participation

Perth Solar Warehouse can provide a SigenStor assessment and proposal that’s specific to your roof, tariff, and household load shape—rather than generic “battery brochure math”.

Navigating the Synergy solar feed-in tariff with ease

Synergy Solar Feed in Tariff Perth WA by Perth Solar Warehouse

If your power bills have been climbing and it feels like you’re doing everything “right” but still paying more, you’re not alone. The good news is that if you consider adding rooftop solar, Synergy’s solar feed-in tariff can provide a credit on your bill for the electricity you don’t use at home and send back to the grid.

Contents

What Synergy’s “solar feed-in tariff” is
When your solar panels generate more electricity than your home uses, the excess power can flow back to the grid. Synergy tracks that exported electricity and applies a credit to your bill under the Distributed Energy Buyback Scheme (DEBS).

What this means for your bill
The credit helps, but it’s not the main event. Most homeowners save the most money by using more of their solar power at home first (for example, running appliances during the day). The export credit is a helpful extra, more so if you can export during the higher-rate window.

Two time windows, two credit rates
DEBS pays one rate during the late afternoon and evening (when demand is higher), and a lower rate at other times. This can feel frustrating, but it also provides a simple strategy: try to shift some usage into the daytime and let more export occur later in the afternoon when possible.

Price schedule

Updated annually: Synergy DEBS pricing schedule effective 1 July 2025 for South West Interconnected System (SWIS) customers only.

Eligibility checklist

Use this checklist to quickly work out whether you’re likely eligible, without wading through pages of fine print. If you tick most boxes, your next step is usually an application (often handled by your installer).

Quick eligibility (most homeowners)

  1. You’re a Synergy customer (generally Perth and much of the south-west).

  2. You’re a residential customer, or you’re an eligible not-for-profit or educational organisation.

  3. Your system size is within the scheme limit (commonly “5 kW or less” for the main device that connects your solar to the home and grid).

  4. You (or your installer) will apply to connect the system and obtain approvals from both Synergy and the network operator (Western Power in most Synergy areas).

  5. You’ll have the right meter in place so exported electricity can be measured correctly.

  6. You can accept the DEBS contract terms when prompted during the process.

If you already have solar and you’re upgrading

  1. If you change your system (for example adding more panels or making other upgrades), you typically need to notify/apply again so the right approvals and metering settings are in place.

  2. If you were on an older buyback arrangement, upgrading may move you onto DEBS rates.

If you have (or want) a battery

  1. Battery exports can be credited under DEBS (the same buyback rates can apply to exported electricity).

  2. Make sure it’s set up correctly by your installer so you stay compliant with local network requirements.

Application steps

The process is simpler than it sounds when broken down. Here are the steps most homeowners follow. Step-by-step: how to get onto Synergy’s DEBS:

  • Decide what you’re doing: new solar or an upgrade. If you’re unsure, start by checking your latest bill and any paperwork from your current system.
  • Choose an installer (or confirm your plan if you already have one). Ask them upfront: “Will you handle the Synergy and Western Power paperwork for me?” Many installers, such as PSW, do—this alone can remove most of the hassle.
  • Submit the required application. You (or your installer) will complete the relevant distributed energy application and engage with both Synergy and the network operator.
  • Complete network approval checks. The network operator reviews whether your system can connect under local rules and what settings are required.
  • Get metering sorted (if required). Your meter may be upgraded or reprogrammed so exports can be measured correctly. If charges apply, they’re typically added to your next Synergy bill.
  • Accept the DEBS terms when prompted. This may happen online during the application process or during a move-in process if you’ve moved into a home with an existing system.
  • Check your next bill for the line item. Look for wording that indicates exported electricity credits/buyback payments. If you don’t see it, contact Synergy (or ask your installer to confirm metering and acceptance steps are complete).

Note: Solar installation companies managing your project with an installation target date beyond three months may reserve application submission until within 90 days of the target installation date.

Frequent questions

Will this actually reduce my power bill?

Using solar power at home first usually leads to the most significant reduction in your electricity bills. While the export credit is valuable, especially if you often send power back to the grid during peak rate times, it’s more of a token credit on top of the savings achieved from self-use.

It depends on how much unused electricity your home exports and when that export occurs. If you’re trying to estimate savings, start simple:

  • check how often you’re exporting now (some bills or monitoring apps show it),
  • assume some exports occur outside the higher-rate window,
  • treat export credits as a “nice extra” rather than the primary driver of payback.

Observation: It is rare to see a DEBS bill credit exceeding $30 for each bimonthly billing cycle.

Yes. DEBS credits apply to the first 50 kWh of exported units per day, per premises. For most homes, this limit is unlikely to be a problem; however, it’s essential to be aware of its existence.

You can still receive export credits with a battery, and exported electricity from a battery can be credited under the same DEBS buyback rates. The practical difference is that a battery may help you store more of your solar energy for evening use, which can reduce the amount you need to buy from the grid.
Once the correct metering is set up and you have accepted the DEBS terms, you will see credits on your bill listed as two separate line items, one for each rate. If you have moved into a home with an existing system, you may start receiving DEBS rates immediately upon your move-in, provided you meet the eligibility requirements and complete the application and metering processes.
Start with one or two easy switches: run the dishwasher or washing machine during the day, and avoid running everything at once in the evening. Even small changes can reduce the amount of electricity you need to buy at full retail prices.
 
Tip: Consider using your Air Conditioner as a battery (thermal mass) in the middle of the day, even when you’re not at home. By using excess solar energy when it is abundant, you can avoid high energy demand later in the day. Always measure your energy load with an energy consumption monitor to ensure that your air conditioner operates within the range of your solar production.

This milestone recognises consistently high standards in the delivery of Sigenergy battery storage systems, from design and installation through to commissioning, handover, and ongoing support. Backed by the wider PSW Energy team (50+ staff operating across greater Perth and South West, WA), Gold status reflects a capability that can be delivered repeatedly at scale, without compromising quality.

Quick insight

  • Perth Solar Warehouse, alongside PSW Energy, has achieved Sigenergy Gold Installer status, Sigenergy’s highest non-exclusive installer tier.
  • Gold status signals strong performance across training, installation quality, commissioning discipline, and customer outcomes.
  • Homeowners benefit from higher confidence in system design, safety, performance, and long-term support.

Contents

Battery storage is now a mainstream consideration for Perth homeowners seeking greater energy independence, better self-consumption, and resilience during grid disruptions. In a fast-moving market, manufacturer-backed installer tiers provide a practical shortcut: they indicate which businesses can integrate and support battery systems to a consistent benchmark — not just sell the hardware.

Achieving Gold Installer status positions Perth Solar Warehouse among the leading delivery teams for Sigenergy systems in Western Australia, with the operational depth to maintain quality across a growing volume of installs.

What Sigenergy Gold Installer status means

Sigenergy’s installer recognition tiers are designed to reflect real-world delivery capability, not marketing claims. Gold Installer status typically aligns to high performance against criteria such as:

  • Completion of advanced manufacturer training and ongoing technical upskilling

  • Proven competence in battery system design, installation, and commissioning standards

  • Strong quality assurance and documentation practices

  • Customer satisfaction outcomes and dependable post-install support pathways

In short, Gold status is a manufacturer-aligned signal that the business can install, configure, and support Sigenergy systems to a consistently high standard.

Why it matters

For homeowners, the installer determines whether a battery system performs predictably over the long term. Gold status matters because it points to stronger execution in the areas that most affect household outcomes:

  • Correct sizing and design for your usage profile, tariffs, and future electrification plans

  • Clean integration with existing solar, switchboards, and protection devices

  • Proper commissioning, monitoring setup, and a clear handover so the system is actually usable

  • Aftercare that’s structured and responsive if settings, firmware, or system behaviour needs attention

This is particularly important for households considering backup-capable configurations, where commissioning accuracy and safe integration are non-negotiable.

Built on scale, standards, and support

Perth Solar Warehouse’s Gold milestone is underpinned by the broader delivery backbone of PSW Energy, forming a combined 50+ person operation servicing the Perth and South West region of Western Australia. That scale matters because it enables consistent training, standardised processes, and stronger continuity of service over time.

“Gold status reflects more than product knowledge; it reflects how you deliver, commission, and support systems day after day,” said Derek McKercher, Director. “For homeowners, it’s a confidence signal that the installation and aftercare will match the quality of the technology.”

Gold status is a benchmark to maintain. Perth Solar Warehouse will continue investing in training, commissioning discipline, and customer education so every installation meets the same standard — whether it’s a first battery, a retrofit, or a future-ready system designed for electrification.

Western Australia’s battery rebate and no‑interest loan program is no longer “proposed”. The WA Residential Battery Scheme opened on 1 July 2025 and is currently operating across both Synergy and Horizon Power customer areas. The scheme provides a WA Government rebate (discounted off the installed battery cost) and, for eligible households, an optional no‑interest loan administered by Plenti. Participation in a Virtual Power Plant (VPP) is a core requirement.

What you can get in 2026 (WA Residential Battery Scheme only)

The scheme provides a WA Government rebate that reduces the installed cost of an eligible home battery. The rebate is calculated per kWh and capped at 10 kWh. The rebate rate depends on your electricity service area:

• Synergy: $130 per kWh (up to $1,300 for 10 kWh)
• Horizon Power: $380 per kWh (up to $3,800 for 10 kWh)

No-interest loan (optional, means-tested). If you qualify, the scheme also includes a no-interest loan administered by Plenti:

• Loan size: $2,001 to $10,000
• Term: 3 to 10 years
• Interest: 0% (fixed)
• Credit assessment applies (Plenti administers applications, approvals and repayments)
• Household gross annual income must be under $210,000 (means-tested)

What the loan can cover: Scheme guidance states the loan can be used for the battery and related new or upgraded equipment (such as inverters and solar panels), provided it’s installed as part of a battery package under the scheme.

Note on federal incentives: Federal incentives are separate from the WA scheme and have their own eligibility rules and timing. If you want a WA-specific explanation of current federal battery incentive changes, 13 Dec 2025, Learn more ›

Fast eligibility check (30 seconds)

You are likely eligible for the WA battery rebate if all of the following are true:

  • Your electricity account is with Synergy or Horizon Power
  • The battery will be installed at a residential property in Western Australia
  • The battery system is new and has at least 5 kWh of usable capacity
  • You will join an eligible VPP (mandatory)
  • You will purchase and install through an accredited vendor using approved products for your network area
  • The battery was not installed before 1 July 2025 (no retrospective claims).

If you want the no-interest loan as well, your household’s gross annual income must be under $210,000, and you’ll need to meet Plenti’s credit requirements.

Eligibility criteria

1. Who can apply (applicant). You must:
• Be a permanent resident of Australia
• Be 18 years or older
• Be a Synergy or Horizon Power customer

For the loan, you must also have a household gross annual income under $210,000 (verified as part of the application process).

2. Property rules (homes). Eligible properties include:
• Residential properties in WA (including some rentals, with the required permissions)
• Owner‑occupied homes and long‑term rental scenarios can be eligible, provided the correct owner/tenant approvals are in place

Common property disqualifiers to watch for: 

  • Non‑residential premises
  • Properties owned by excluded entity types (for example, certain government and institutional ownership categories listed in scheme guidance)
  • Apartments/strata where electricity is supplied through an embedded network (eligibility can depend on billing and metering arrangements)

3. Battery and inverter rules (product eligibility). At a minimum:

• The battery must be new and at least 5 kWh usable capacity
• The battery and inverter must be on the approved lists for your area (for example, Synergy supported solutions or Horizon Power approved lists) and meet technical requirements
• Components must align with relevant standards and approved product listings where required by the scheme and network rules

4. VPP participation is mandatory. To access the WA battery rebate and/or loan, households must participate in a Virtual Power Plant (VPP).

What joining a VPP means

A VPP links participating household batteries so stored energy can be dispatched at certain times (for example, during peak demand events), under the terms of the VPP agreement.

The scheme materials state the VPP agreement period is two years, after which participants can opt out.

The scheme guidance also notes some existing solar systems may need upgrades to meet remote management requirements and current electrical standards (often described as “whole of site compliance”). This can include replacing or upgrading components and/or wiring.

How to apply in 2026 (current process)

The application pathway has effectively been standardised:

Step 1: Confirm eligibility. Start with your retailer area (Synergy vs Horizon), residential property status, and whether you’re willing to join a VPP (required).

Step 2: Choose an accredited vendor. Applications are submitted by scheme-approved vendors (homeowners don’t lodge rebate applications directly).

Step 3: Select approved products. Your vendor should confirm the battery/inverter combination is on the relevant supported solutions lists and meets technical requirements.

Step 4: Vendor submits the rebate application (and the loan process, if needed). If you opt for the loan, Plenti will contact you to complete the income and credit assessment steps.

Step 5: Install and connect (including VPP onboarding). The scheme includes timing constraints and compliance steps. Practically: don’t treat conditional approval as open-ended—book installation promptly once approved.

Program duration and availability. The WA Government has stated the scheme will run until the allocated number of rebates is used (up to 100,000). Availability can change with uptake, so it’s worth checking funding availability before you proceed.

How this compares to other solar incentives in WA (2026)

1. Federal STCs for solar panels. Most rooftop solar systems in Australia are supported through STCs under the federal Small-scale Renewable Energy Scheme, typically delivered as an upfront discount at point of sale.. Guide: Solar rebate Perth & Bunbury region simplified (zone 3) ›

2. Federal Cheaper Home Batteries Program (battery STC discount). This federal initiative supports the combined WA Residential Battery Scheme guidance for a 10 kW battery as part of the initial scheme, offering $5,000 from Synergy and $7,500 from Horizon. The state announced these rebates to promote the broader distribution of this program. Announced December 13 2025, the Federal Cheaper Home Batteries Program’s value dilutes ›

Cheaper Home Batteries Program key points (as of 2 January 2026 on the Clean Energy Regulator’s program page):

• Around a 30% upfront discount, gradually decreasing until 2030.
• Eligible battery nominal capacity: 5 kWh to 100 kWh.
• STCs calculated on usable capacity; claimable for the first 50 kWh of usable capacity.
• Must be installed with a new or existing solar PV system
Installed by an appropriately accredited installer (such as PSW) and compliant with standards

What’s different about the WA battery rebate: it’s a state co‑contribution that stacks with the federal battery STC discount and is specifically tied to VPP participation.

3. Feed‑in tariffs/export credits Export credits in WA are generally time-based rather than a single flat rate. In the Synergy (SWIS) area, the Distributed Energy Buyback Scheme (DEBS) uses peak and off-peak export rates. In Horizon Power areas, buyback rates can vary by location and product.

Synergy (SWIS): Distributed Energy Buyback Scheme (DEBS) price schedule (effective 1 July 2025) lists:

• Peak export (3pm–9pm): 10 c/kWh
• Off‑peak export (before 3pm or after 9pm): 2 c/kWh

Why this matters when comparing “battery vs no battery”: batteries are often most valuable when they reduce imports during expensive peak demand periods (and when they shift midday excess solar into evening self‑consumption). DEBS is a credit for exports; it doesn’t replace the value of avoiding retail-priced imports.

Horizon Power: buyback rates vary by town + Community Wave options. Horizon Power’s buyback pricing factsheet (1 July 2025 to 30 June 2026) shows DEBS export rates by town classification, for example:

• Low‑cost towns: 3.00 c/kWh off‑peak; 10.00 c/kWh peak
• Medium‑cost towns: 11.33 c/kWh off‑peak; 37.76 c/kWh peak
• High‑cost towns: 16.80 c/kWh off‑peak; 55.99 c/kWh peak

The same document describes a “Buyback Bonus” available to Community Wave customers, with seasonal and time‑of‑day rates (Community Wave is Horizon Power’s VPP offering).

Examples: who qualifies and who doesn’t

Homeowner on Synergy, buying a new 10 kWh battery from an accredited vendor such as PSW

Will join an eligible VPP

Result: likely eligible for the WA rebate and the combined rebate outcome, subject to approved product lists and installation compliance.

Same criteria as Example A, household gross income under $210,000

Result: may be eligible for the no‑interest loan (credit assessment applies).

Tenant on Synergy with the landlord’s written consent to install a battery

Result: potentially eligible if approvals are in place; confirm early because ownership/tenancy paperwork is commonly required.

Battery installed before 1 July 2025

Result: not eligible for WA rebate/loan; and federal STC rules also require the battery to be certified as installed on/after 1 July 2025 for eligibility.

Apartment/strata with electricity supplied via an embedded network or body corporate arrangement

Result: eligibility can be complex; the WA scheme is linked to having a Synergy or Horizon account for the premises, and the WA Government flags these arrangements as case‑by‑case.

Next steps

If you believe you qualify, the most effective next step is to move from “reading” to “documentation”:

1. Confirm your retailer area (Synergy vs Horizon) and whether you’re willing to join a VPP.

2. Get an itemised quote from an accredited vendor using approved battery + inverter options. Consider Perth Solar Warehouse.

3. If you want the no‑interest loan, pull your most recent tax return (the scheme guidance references verification against tax returns) and be ready for Plenti’s credit assessment process.

Perth Solar Warehouse, under the co-owned brand PSW Energy, is listed by Plenti as an accredited WA Residential Battery Scheme vendor (Synergy area). If you want us to check eligibility against the current approved lists and lodge the rebate application through the correct channel, request a battery quote and note whether you’re also considering the no‑interest loan.

What has changed since the original pre-rebate article

  1. The scheme is live, not “soon‑to‑be introduced”.
    Applications opened on 1 July 2025 and are submitted via approved vendors.

  2. The rebate is not a flat “$500 per kWh” WA payment. As of June 30, 2025, ahead of the operating scheme, the WA portion is redistributed as $130/kWh (Synergy) or $380/kWh (Horizon) offer, capped at 10 kWh, and the larger “up to $5,000 / $7,500” figures now reflect stacking with the federal battery STC discount.

  3. VPP participation is not optional.
    It’s a stated eligibility requirement for the WA rebate and loan.

  4. Application hygiene matters more.
    Consumer Protection has explicitly warned households to use care with pre‑scheme sales tactics and to avoid high‑pressure marketing; in 2026, the practical equivalent is: verify vendor accreditation, insist on itemised quotes (showing rebates/discounts separately), and check product approvals before paying deposits.

Personal data privacy in a home solar or battery purchase?

Energy consumption data monitored by a modern solar energy system provides privileged insight into the pulse of your home or business’s operation. When most people invest in solar energy, they consider savings, reliability, and long-term energy independence. Increasingly, another question sits quietly in the background: how secure is the technology behind it?

Contents

Key insights

  • Connected solar systems generate data through smart inverters and monitoring platforms, making transparency and responsible data handling essential.
  • Most cybersecurity risks are manageable with proper system configuration, strong access controls, and regular software updates—not fear or complexity.
  • Perth Solar Warehouse prioritises security by design using trusted technology partners and clear, customer-first data protection practices.

Modern home solar energy systems have evolved beyond just panels and wiring. They now incorporate smart inverters, energy consumption data, online monitoring platforms, and grid connectivity for optimal performance. While this connectivity offers significant advantages, it also raises valid concerns about data privacy and cybersecurity.

Where concerns usually arise

For customers, concerns tend to focus on a few key areas:

Smart energy systems and monitoring apps. These devices track the amount of energy a system produces and uses, often in real-time. While this data helps optimise performance and flag faults early, it can also reveal patterns about when a home is occupied or how a business operates.

Remote access and grid connection. Cloud-based dashboards allow owners and installers to view system performance from anywhere. Like any online service, security depends on strong passwords, controlled access and regular software updates.

Data privacy. Customers want to know what data is collected, where it is stored, and who can access it—especially in businesses, where energy data can reveal commercial activity.

These are legitimate considerations, not reasons for alarm. As PSW Energy has highlighted in its own consumer guidance, the real issue is not connectivity itself, but whether cybersecurity and data handling are treated as core design features rather than afterthoughts.

Keeping risk in perspective

The most common risks in solar systems are not dramatic cyberattacks. They are simple issues such as default passwords left unchanged, outdated firmware, or unclear access controls. When systems are properly configured and supported, the likelihood of unauthorised access is very low.

For homeowners, the impact of a security lapse is usually limited to privacy and peace of mind. For commercial customers, the stakes can be higher, which is why transparency and good system design matter even more.

How PSW approaches security

At Perth Solar Warehouse, we prioritise cybersecurity as part of our system quality. We adopt a consumer-awareness approach similar to that of PSW Energy, but with a clear emphasis on what matters most to our customers in their daily lives. In practice, this means we:

  • Select reputable technology partners with a strong track record in security.
  • Configure our systems to limit access only to those who absolutely need it.
  • Ensure that monitoring platforms are established with sensible security controls from the very beginning.
  • Treat customer energy data as confidential, rather than as a product to be shared or sold.

Moreover, we strive to explain these choices in simple, easy-to-understand language. Our customers should not have to decipher technical documentation to understand how their data is handled.

Customers should feel comfortable asking

As a homeowner or business owner, it’s important to ask the following questions:

1. What data does my system collect, and for what purpose?
2. Where is this data stored?
3. Who has access to my monitoring platform?
4. How are software updates and security patches managed?

Clear and straightforward answers to these questions are often the best indicators of a provider’s commitment to security.

Confidence, not fear

Solar and battery systems are long-term investments. They will sit quietly on your roof or in your utility room for decades, generating power and data every day. Understanding how that data is protected is not about worrying; it’s about building confidence.

It is entirely possible to have secure and privacy-conscious solar systems. When providers prioritise transparency, reasonable safeguards, and responsible data practices, customers can enjoy the advantages of modern energy technology without unnecessary concerns.

If you would like to discuss how Perth Solar Warehouse designs and supports secure solar installations, whether for residential or commercial purposes, our team is always available for a transparent and honest conversation.

Cheaper Home Batteries Program Changes for WA Households

On Saturday, 13 December 2025, the Australian Government announced essential updates to the Cheaper Home Batteries Program, which will commence on 1 May 2026. For Perth and wider Western Australian households, these changes don’t remove the battery discount – but they do affect how much support you can receive and when it makes most sense to install a system.

This article walks you through what’s changing, what’s staying the same, and how to plan your next steps with confidence.

Contents

Key points

  • The federal battery program is expanding significantly: The Australian Government has increased funding for the Cheaper Home Batteries Program from $2.3 billion to an estimated $7.2 billion, aiming to support over 2 million battery installations by 2030.
  • The rebate calculation will change from 1 May 2026: From this date (subject to regulations being made), the STC Factor will be reduced and adjusted every 6 months, meaning the per-kWh discount will gradually decline faster than previously planned.
  • Support will be tiered based on battery size: After 1 May 2026, the rebate will apply at: 100% of the STC Factor for the first 0–14 kWh, 60% for 14–28 kWh, and 15% for 28–50 kWh of usable capacity.
  • Timing matters for households planning to install: Your installation date determines the rebate. Installing before 1 May 2026 locks in the higher current STC Factor and avoids the new size-based tapering. Installing after this date still offers substantial discounts, but at reduced levels, especially for medium and large systems.

A quick refresher of how the Cheaper Home Batteries Program works now: The Cheaper Home Batteries Scheme (battery rebate) is a national initiative designed to make battery storage more affordable by reducing the high upfront cost that has traditionally held people back. Right now, the program:

  • Provides a discount of around 30% off the upfront cost of eligible battery systems between 5 kWh and 50 kWh.

  • Applies to batteries connected to new or existing solar PV systems.

  • Delivers the discount through Small-scale Technology Certificates (STCs) under the Small-scale Renewable Energy Scheme (SRES).

  • Is funded by the Australian Government and administered by the Clean Energy Regulator (CER).

In practical terms, most customers see the benefit as an upfront reduction on their quote or invoice, with the installer or retailer handling the STC side of things in the background. You can instead choose to manage STCs yourself through the REC Registry, but most people prefer the simpler “discount on the bill” option.

The program is also designed so that the discount will be reviewed at least annually and gradually decrease until 2030, in line with expected reductions in battery prices.

What exactly was announced on 13 December?

On 13 December 2025, the government announced that the Cheaper Home Batteries Program will be significantly expanded and adjusted from 1 May 2026. The key points are:

  • Program funding will increase from the original estimate of $2.3 billion to an estimated $7.2 billion over the next four years.

  • The government expects this to support over 2 million battery installations by 2030, adding around 40 GWh of storage capacity to the grid.

  • To keep the discount “about right” as batteries get cheaper, the way the discount is calculated will change from 1 May 2026.

Those calculation changes revolve around two levers:

  1. The STC Factor (how many STCs you get per kWh of battery capacity).

  2. How that factor is applied to different battery sizes.

Change 1: Faster and deeper reductions to the STC Factor

Currently, the discount you receive depends largely on a single number called the STC Factor, which represents the number of STCs you can create per kilowatt-hour (kWh) of usable battery capacity. From 1 May 2026, the government plans to adjust this factor so that it:

  • Declines more frequently – every 6 months, instead of annually.

  • Declines at a higher rate than initially planned.

The formal table in the announcement indicates that for the period 2026–2030, the existing STC Factor and the proposed new STC Factor begin to diverge. For example, in 2026:

Year
Period
Existing STC factor
Proposed STC factor
2026
January — April
8.4
8.4
2026
May — December

January — June
4.7
2.6
2030
July — December
4.7
2.1

Source: Department of Climate Change, Energy, the Environment and Water, Table 1

The pattern continues in later years, with the proposed factor dropping more quickly in each 6-month period than previously planned.

What this means for you: The date your battery is installed determines which STC Factor applies. A battery installed before 1 May 2026 will use the higher existing factor, while one installed on or after 1 May 2026 will use the lower proposed factor for that period.

Change 2: Tiered support based on battery size

The second big change is how the STC Factor is applied across different battery sizes. Today, the calculation is relatively simple: the same STC Factor applies to each kWh of usable capacity, up to the program’s cap, so larger systems attract proportionally larger discounts.

As of May 1, 2026, the program will continue to support batteries up to 50 kWh, but the level of support will decrease as the system size increases. The proposal sets out three capacity bands for the first 50 kWh of usable storage:

Banding – kWh
STC Factor
0 kWh up to 14 kWh (inclusive)
The STC Factor applies at 100% (full value)
Every kWh greater than 14 and up to 28 kWh (inclusive)
The STC Factor applies at 60% of its value
Every kWh greater than 28 and up to 50 kWh (inclusive)
The STC Factor applies at 15% of its value
You can still install up to 100 kWh, but the rebate calculation tapers off after 50 kWh.

In simple terms:

  • Smaller and moderate-sized batteries (up to about 14 kWh) will continue to receive the strongest support per kWh.
  • Larger systems will still get help, but each extra kWh beyond 14 kWh will attract less rebate, and even less again once you pass 28 kWh.
  • The new structure is designed to maintain an overall discount of around 30% for common system sizes, aligning with declining battery costs and ensuring the budget can support more households.

Eligibility under the updated program

The announcement on 13 December focuses on changes related to funding and calculation but does not alter the eligibility criteria for participation. Most households in Western Australia will still need to meet the following requirements:

  • You are an Australian household, business or community organisation installing an eligible battery.

  • The battery is 5–100 kWh usable capacity and connected to rooftop solar.

  • The battery and installer both meet accreditation and safety requirements outlined in the Renewable Energy (Electricity) Regulations 2001.

  • The system is installed and documented in a way that allows STCs to be created for the battery component.

For more detailed eligibility conditions, the government still directs people to the full regulations and official eligibility guidance.

PSW Customer FAQ's

Our responsibility is to minimise PSW customer inconvenience due to this adjustment in battery rebate values.

Priority 1: Existing customers. We’ve been building improved installation capacity over the Q4 2025 period. This will ensure existing PSW customers scheduled from May 1 2026 have the opportunity to come forward to ensure the rebate amount remains unchanged.

Most likely reschedule date availability: March or April 2026.

If your installation date can not be brought forward, a contract revision is required.

No.

The advertised battery package costs on the Perth Solar Warehouse website is receiving an update from December 15 to December 31st to factor the new rebate variables.

Possibly. Your rebate is determined by the installation date, not the quote date.
If your install occurs after 1 May 2026, the new lower STC Factor and tiering rules will apply.

Our first priority, given the shift is to existing customers and ensuring their installation can be scheduled earlier.

Yes.

If the quoted rebate was calculated under the current STC Factor and you install after 1 May 2026.

It’s best to request an updated quote reflecting both pre- and post-May scenarios. Please note that within one week of the announcement we are adjusting forms and quoting templates and this information may not be available (pre-Christmas 2025).

Yes.

Yes. The federal program is designed to work alongside state schemes, including the WA Residential Battery Scheme.

Eligibility criteria for each scheme are separate, so you may be able to receive both, depending on your circumstances.

Important: In scenarios like this, inbound customer inquiries surge. With a limited amount of locally based staff, we’ll do our best to respond promptly. However, please note that there will likely be a delay in response times.

2x Your SigenStor DCEV charging speed with a software upgrade

If you purchased a 12.5 kW Sigenergy SigenStor EVDC Charger from Perth Solar Warehouse, you have great news: your charger can now be upgraded to a 25 kW charging capacity through an over-the-air software update. This means no new hardware, no electrician visit, and no disruption.

This manufacturer-supported upgrade allows eligible customers to unlock double the charging power with a paid software license. As a result, you’ll enjoy faster EV charging and greater long-term value from the system you already own.

Contents

Key insights

  • Double your charging power instantly: Upgrade your existing 12.5 kW Sigenergy EVDC Charger to 25 kW via a simple over-the-air software unlock, with no hardware changes or site visit required.
  • Gain the performance of a 25 kW DC charger for a fraction of the cost of replacing your unit, delivering faster charging, improved future EV compatibility, and better use of your solar and battery system.

Unlocking the 25 kW charging capability offers several real-world benefits, including significantly faster charging times that are particularly advantageous for busy households or those with multiple electric vehicles. This upgrade also reduces wait times when topping up your vehicle, allowing for a more efficient driving experience. Furthermore, it enhances the utilisation of solar, battery, and grid power within your Sigenergy system, making it a more sustainable option.

Significantly, this enhancement raises the maximum charging limit of your EVDC charger from 12.5 kW to 25 kW. However, it is essential to note that the actual charging power available at any given time will still depend on factors such as the energy generated by your solar PV system, battery capacity, inverter rating, and grid input. This is normal system behaviour and does not indicate a fault.

Performance expectations (very important)

After upgrading to 25 kW, your Sigenergy EVDC charger will be capable of delivering up to 25 kW of DC charging power, provided that sufficient energy is available in your system. This device unlocking means faster charging when solar production is strong, battery capacity is available, or grid support is enabled.

If energy availability is limited, such as during low solar output or when household energy demands are high, the charger will automatically adjust and operate at a lower power level. This behaviour is normal and ensures that your system operates safely and efficiently, while also taking advantage of higher charging speeds whenever conditions permit.

No Hardware Changes – 100% Over-the-Air

One of the most significant advantages of this upgrade is convenience. The 25 kW capability is unlocked via a software license activated remotely using the mySigen app. That means:

  • No charger replacement
  • No rewiring or physical modifications
  • No technician site visit required

Once the license is purchased and activated, the charger is digitally upgraded and ready to deliver higher power when system conditions permit. For older EVDC units, Sigenergy provides an updated nameplate at no charge to ensure regulatory compliance.

Cost

The fee to unlock the 25 kW upgrade is $1,100 AUD. This represents an exceptional value compared to purchasing a brand-new 25 kW DC charger and covering the installation costs. By choosing the upgrade, you effectively double your charger’s capacity at a fraction of the cost of replacement, all while retaining the trusted Sigenergy hardware that is already integrated into your energy system.

How to Get Started

If you’re interested in upgrading and unsure how to move forward with confidence, Perth Solar Warehouse is here to help ensure that PSW customers have a suitable system and guide them through the process. Alternatively, if you’re ready and willing, follow these three steps:

  1. Open the mySigen app and visit the Mall section.
  2. Purchase the SigenStor EVDC 25kW Fast Charging License with a credit card.
  3. Receive your License Key, copy it, and activate it on your specific EVDC device.

Note: For older EVDC models, a free replacement nameplate will be provided and must be installed to meet local regulatory requirements.

The homeowner’s guide to Australia’s Tindo Solar panels

The homeowner’s guide to Australia's own Tindo Solar panels

For Australian homeowners considering solar options, Tindo Solar is a distinctly local choice. As the only mass-market solar panel manufacturer in the country, Tindo panels provide features that many imported brands lack: engineering specifically designed for Australian conditions, rigorous domestic quality control, and warranty support that is fully managed onshore.

This guide offers a comprehensive overview of Tindo’s current solar panel lineup, including insights on performance, warranties, pricing, and a comparison to mainstream brands. Whether you are new to solar energy or looking to compare options for your home, this overview aims to give you the clarity you need to make an informed decision.

Contents

Key points

  • Australian-made for Australian conditions: Tindo panels are locally manufactured in Adelaide and engineered specifically to withstand high heat, strong UV exposure and harsh weather, offering long-term reliability in Australian climates.
  • High-quality N-type technology: The Walara series uses modern N-type TOPCon monocrystalline cells with strong efficiency, slower long-term degradation and robust construction, ensuring consistent performance over 25+ years.
  • Stronger warranty and easier support: With a 25-year product and performance warranty handled directly within Australia, Tindo offers easier, more reliable after-sales support than many imported brands.
  • Higher upfront cost, stronger long-term value: While more expensive per watt than many global brands, Tindo’s superior build quality, domestic quality control and local backing provide better lifetime value and peace of mind.

When we say Australian-made, many homeowners appreciate that warranty support is provided by an Australian company with a physical presence, rather than relying on offshore distributors.

Tindo Solar panels are promoted to be designed for the harsh Australian climate. Such a claim would enable them to perform reliably under high temperatures, UV exposure, and variable weather conditions, further enhancing their long-term durability. Verified specifications can often assist in this regard, and we will compare these figures against those of international mainstream brands below. 

Which to consider

Tindo’s latest residential product range is the Walara series, which features two high-performance monocrystalline N-type TOPCon models: the Walara 440 W G4P and the Walara 475 W Full-Black Edition. Both models utilise advanced cell technology designed to maximise efficiency while ensuring stability in extreme heat conditions.

Datasheet

1. Tindo Walara G4P (440 W): The Walara 440 W is designed to fit comfortably on standard residential rooftops, with dimensions of approximately 1722 × 1133 × 35 mm and a weight of around 21 kg.

2. Tindo Walara G4P-BL (475 W): The larger 475 W Full-Black panel, perfect for homeowners looking for a sleek all-black design, measures approximately 1910 × 1133 × 35 mm and weighs around 23.5 kg.

The N-type TOPCon cell technology used in these modules offers superior resistance to long-term degradation compared to older P-type cells, which means the panels are less likely to lose efficiency over time. Additionally, each panel features a 16-busbar design, which reduces internal resistance and enhances energy capture during variable light conditions—an essential factor for rooftops that may experience partial shading or inconsistent orientation.

Performance, Heat Behaviour and Longevity

Due to the extremely high rooftop temperatures in Australia, solar panels must perform effectively in hot environments. Tindo’s Walara solar panels can safely operate at temperatures up to 85 °C and have a temperature coefficient of approximately -0.30% for every degree above the standard test temperature of 25 °C. This rating means that for each degree the panel temperature exceeds 25 °C, its output decreases by only 0.30%. While all solar panels experience efficiency loss in high temperatures, Tindo’s panels are specifically designed to compete with leading global brands in terms of high performance, under standard test conditions. CHOICE proven, rest assured knowing that Australia’s home-grown solar panel brand is engineered for long-term stability in hot, high-UV non-standard test conditions.

A typical 6.6 kW residential solar system using Tindo panels can produce approximately 20 kWh of energy per day during winter and up to 40 kWh per day during summer (in Perth, Western Australia), depending on various installation factors. Tindo’s Walara panels are designed to maintain high output over the decades due to the slower degradation rates associated with N-type technology. Tindo guarantees that after 25 years, the panels will still produce at least 87.4% of their original rated power. This degradation rate, averaging less than 0.5% annually, places Tindo panels firmly within the modern high-performance category.

What is the warranty

One of Tindo’s most significant benefits is its 25-year product warranty, which covers workmanship, materials and defects. This is paired with a 25-year performance warranty guaranteeing minimum power output over time. In addition to meeting global warranty standards, Tindo’s local presence enables a faster and more transparent claims process for Australian customers. Because the company is based in Adelaide, homeowners can access support directly, rather than through importers or third-party distributors overseas.

Tindo reports extremely low defect rates, crediting its strict “zero-defect” manufacturing philosophy. Each panel undergoes inspection and electrical testing before leaving the factory. It’s worth noting that any micro-inverters or optimisers installed alongside Tindo panels carry their own manufacturer’s warranty, which may be separate from the panel warranty. For this reason, it’s crucial to ensure your installer clearly outlines which components are covered by which manufacturer and for how long.

Where are they made

Adelaide (Mawson Lakes, Technology Park), South Australia. A wholly and independently owned facility dedicated to growing Australia’s opportunity as a proven sustainable energy manufacturer. A virtual onshore company, Knighthood in Australia, Tindo Solar, is distinguished as an ACEPV (Australian Centre of Excellence in Photovoltaics).

What do they cost

As a high-quality Australian-manufactured product, Tindo panels generally fall into the mid-to-upper pricing category. A small residential system of around 6.6 kW is often priced between $5,000 and $6,000 plus inverter or battery cost, roof complexity and installation factors. Many homeowners consider the additional cost worthwhile for the sake of local support, superior build quality and long-term performance.

Who Tindo Solar panels are best suited for

Tindo Solar is an excellent fit for homeowners who value Australian-made products, prefer local warranty support, and are willing to invest in superior long-term durability rather than chasing the lowest upfront price. The panels are ideal for homes exposed to harsh weather or high heat and for buyers who want a clean, integrated aesthetic without sacrificing performance. On the other hand, homeowners with minimal budgets, minimal roof space requiring ultra-high-wattage panels, or those prioritising global premium branding may find imported panels a better match for their needs.

For most Australian homes, and particularly those in Western Australia, seeking reliable performance in hot, sun-intense conditions, Tindo Solar’s Walara 440 W and 475 W panels offer an appealing balance of efficiency, longevity, and locally backed support. They are engineered for local weather extremes, inspected under rigorous quality control processes and supported by one of the strongest warranties available to Australian homeowners. If long-term value, reliability and local presence matter to you, Tindo stands out as one of the most dependable residential solar panel options available in 2025.

Australian-made solar available in WA by Perth Solar Warehouse

Western Australian homeowners have long trusted Perth Solar Warehouse for reliable, high-quality solar solutions. Today, we’re excited to share one of our most significant announcements yet—one that strengthens local manufacturing, boosts supply security, and gives WA families access to some of the most rigorously built solar panels in the country.

Beginning in 2026, Perth Solar Warehouse will offer Australian-made Tindo solar panels as part of our product lineup.

As Director Derek McKercher shared when announcing the partnership on LinkedIn:
“I’m bringing Australian-made solar panels to Western Australia.”

And we couldn’t be prouder to do exactly that.

Why we chose Tindo

Tindo panels stand out because they’re designed and manufactured specifically for Australian conditions, built locally under some of the strictest quality standards in the world. Unlike many imported alternatives, these panels undergo controlled, transparent, Australian-based production processes that ensure exceptional durability and performance, even in WA’s harsh summer heat and coastal environments. For homeowners, this translates directly into long-term reliability and the confidence that your solar investment is built for our climate rather than adapted to it.

Stronger protection

Just as important are the warranties and performance guarantees behind the product. Tindo panels offer a locally backed 25-year product warranty and a strong long-term power output guarantee, underscoring their durability and expected lifespan. With support handled here in Australia rather than offshore, homeowners also benefit from quicker, more responsive service throughout the life of the system. These protections give families the peace of mind they deserve when making a significant energy decision.

A more secure, local supply chain for WA families

The move to introduce Australian-made solar panels also represents a major leap forward for supply chain security in Western Australia. In recent years, global disruptions have affected solar availability worldwide. By partnering with a domestic manufacturer, we’re ensuring a more stable and predictable supply of premium panels, reducing the risks of shipping delays, shortages, or sudden market fluctuations. It’s a shift that not only supports Australian jobs and industry but also directly benefits WA families planning ahead for a reliable solar installation.

Backed by over 20 years of local energy expertise

With over 20 years of local energy expertise, Perth Solar Warehouse has consistently provided homeowners with reliable and well-supported solar solutions. By incorporating Tindo into our offerings, we align perfectly with our mission to deliver quality installations backed by products we truly trust. This partnership not only expands our range but also represents a significant step toward offering better local choices, higher standards, and long-term confidence for residential customers throughout the state.

Tindo solar panels will be available starting in 2026 through Perth Solar Warehouse. We encourage homeowners who value Australian manufacturing, strong warranties, and reliable supply security to begin exploring their options now. If you’re interested in learning more or want to register your interest ahead of the launch, our team is here to assist you every step of the way. Together, we can support Australian innovation while providing Western Australian homes with quality you can rely on.
