The soon-to-be-introduced West Australian solar battery rebate and interest-free loan (Residential Battery Scheme) present an appealing opportunity for solar energy system owners. A capped $328 million package, here’s how you are more likely to secure your position for a share of $5000 off the cost of an energy storage solution on the Synergy electricity network from a 20,000 household allocation state-wide.

Contents

Key points

  • Use existing solar rebates to be battery 'rebate ready' on July 1, 2025
  • Buy solar now with a 'hybrid' inverter, order battery in advance to be stock ready.
  • Proposed offer factors 20,000 out of 900,000 dwellings in Western Australia.

Homeowners with existing solar energy systems are in the best position to take advantage of the impending WA solar battery rebate. Since the original announcement, the West Australian Government has shifted its readiness position ‘from’ July 1 to ‘by‘ July 1 after industry consultation. It’s possible to expedite the process of achieving an earlier release date with existing Australian state-based battery frameworks already available in template form.

There is a $328 million budget from the state: the Synergy network ($5000 per household), the Horizon network ($7,500 per household), and a means-tested $10,000 per household interest-free loan component. With a limited capacity of 20,000 from over 900,000 available dwellings, demand is strong from the impending WA solar battery rebate/Residential Battery Scheme.

How to be prepared for the WA battery rebate

Interested participants should register their interest on the wa.gov.au website. Then, engage a locally headquartered and registered West Australian solar company [Top 10]. However, if you want to fast-track your way to the front of the queue of battery rebate allocations, here are four ultimate tips.

1. Ensure solar exists first (if possible)

  • DC-coupled battery integration is quick. DC-coupled batteries can be installed in less time for a faster qualification process when governed by capacity and implementation criteria.

To be physically prepared ahead of the WA solar battery rebate, ensure a solar-only system with a hybrid DC-coupled inverter. Hybrid inverters refer to the hybrid [solar and battery] power they convert to usable energy.

A hybrid solar inverter can accommodate a solar generation input and a DC-connected energy storage option while delivering usable AC output power for your home. Hybrid inverters also accommodate AC-coupled batteries if you choose. AC-coupled batteries are connected to the inverter via the home’s power supply.

Hybrid inverters act as a central component of its combined energy system. DC separation to the electricity network (Western Power) makes DC-coupled battery integrations more straightforward.

2. Pre-order your battery

  • A pre-ordered battery ensures your product is allocated, approved and ready to use as part of the WA solar battery rebate.

To be physically prepared, equip yourself with a solar home energy system with a hybrid inverter at the heart. Hybrid inverters refer to the hybrid power input they can receive. In this instance, a hybrid solar inverter can accommodate a solar generation input and [nominated] DC-connected energy storage options while delivering usable AC output power for your home.

The hybrid inverter acts as a central component for the combined energy function of the entire system. DC-coupled batteries now become more straightforward as most grid connection approval delays occur due to additional inverter capacity for the grid.

3. Ensure better battery value

  • Cost-per-kWh assists in normalising energy density values between products and ensures maximum value from the WA solar battery rebate.

Solar rebate-eligible battery options are limited. In conjunction with a one-off $500 per kWh, up to 10 kWh ($5000) approved battery rebate on the South West Inter Connected System (Synergy/Western Power) is the means-tested option of a 10-year interest-free loan component to bridge potential adoption gaps for those less likely to afford a subsidised battery system.

Getting lost in kW and kWh terminology is easy when receiving a potential product with no upfront costs. A good way to compare solar battery value is on a cost-per-kWh level to better understand energy density value. Example:

  • A 5kW/ 5 kWh battery costs $7,500 under the proposed WA solar battery rebate. The energy density value is $1500 per kWh. ☹️
  • A 5kW/ 10 kWh battery costs $5,000 under the propsed WA solar battery rebate. The energy density value is $500 per kWh 🙂

Compare: Varying battery ‘performance’ warranties shift energy density value through degrading factors and manufacturer bankability. The installation company serves as the overall system warranty holder for the intended life. For a more assured system warranty, focus on proven qualities and a business reputation aligned with the warranted period.

4. Installation company value

  • Considering a locally proven installer is an improved consideration for aftercare and system warranty assurance.

The solar and battery system company providing the system remains integral to significant ongoing system functions—they’re a purchaser’s first call should assistance be required. A locally proven provider facilitates availability within the same time zone and is a direct point of contact for manufacturers in an aftercare scenario. 

In a sea of national solar companies gravitating towards incentivised state-based schemes as they arise, Perth has a solid list of high-ranking local solar companies to consider as proven home energy system facilitators. The linked article below provides in-depth guidance on a balance of business refining factors and a shortlist of local solar companies with a reputable track record for the proposed WA solar battery rebate.

Ranked as one of the best solar companies in Perth by customer satisfaction

Ranked as one of the best solar companies in Perth by review (2048 x 1536 px) (4)

With enough time, the best solar companies Perth has to offer begin to surface. Over a decade of mainstream popularity and with the internet as a popular research tool, customer satisfaction levels have become apparent with long-standing companies. Companies that have yet to stand the test of time still have untarnished review profiles, or often noticed is the resetting of Google listings to wash away past negativity. However, the review count is evident and easy to determine for any discerning investor.

Every day, a solar company defines itself as Perth’s number one installer, but by what measurement? If it’s volume, that provides little insight into how a company treats their customers (long-term), especially if the capacity achieved is from completing a few very large jobs in a nominated period. Some will hold onto the highest volume credential in a time that is no longer relevant (consumer expectations have changed in 2025). However, the gauge most customers seek is how the considered best solar companies in Perth evolve while attending to their customers over time.

For added depth of research, combine this with leading international business assurances such as ISO-certified business processes and NETCC consumer endorsement for a more defined solar company. Advantageously, Perth’s customer satisfaction averages and solar company certifications are available.

Gauging customer satisfaction

Two reviewing platforms, Google and SolarQuotes.com.au, provide a level of commonality among all of the best solar companies in Perth. Alternative platforms exist, such as ProductReview and TrustPilot, but these are marketing machines that reap the rewards when organisations subscribe for benefits and the ability to pre-screen negative sentiment through review gating. Appealing for some but not the most transparent gauge for customers.

Google is open slather for everyone. It’s an excellent tool to ensure companies are on high alert, even those that have yet to purchase from them. Always be wary of low review counts and no mixed opinions.

Tip. Even though Google has improved legitimacy, spot dubious reviews when comparing:

  1. The number of reviews reviewers have made.
  2. The average review content/length (Short = Less good. Longer = Better).
  3. Assess the lowest reviews to see how a company responds to dissatisfaction.
  4. A small amount of dissatisfaction is a good thing. It provides a benchmark for evaluating the business and its performance in adverse scenarios.

SolarQuotes.com.au is contentious because paid elements exist for installers. Therefore, solar companies that purchase leads from solarquotes.com.au naturally have more reviews than those that don’t, as the platform always follows up the experience should a lead-purchasing solar company win your work. Unlike alternatives, SolarQuotes.com.au reviews are good for purchasers identifying different elements of installer competency. Those among the best solar companies in Perth have customer reviews here – even the non-subscribers, as SolarQuotes.com.au is a popular customer research tool for most.

 SolarChoice.com.au is similar to the SolarQuotes.com.au website. The installer review section is new, so the review count for most currently considered ‘top-rated Perth solar companies’ is low. SolarChoice.com.au’s online content is detailed and free for serious sustainable energy investors doing their research. Due to trust with search engines, solar companies have their reviews prioritised through SolarChoice.com.au ahead of alternative platforms.

Facebook’s business reviewing mechanism is as credible as Facebook Marketplace before 2023. It had been rarely supported, and reviews could be purchased from vendors that many exploited. Perth Solar Warehouse Facebook recommendations are genuine but urge customers to exercise caution when comparing companies here.

Criterea that can be measured

1) Time is an outstanding measurement. Given that most warranties are 10 years or longer, you need a company that’s been around 10 years or longer a proven history of customer experiences. Your solar investment is only as good as its installation company, simple. The longer, the better. Ask yourself, are you buying a dream or a proven energy supply? Choose a company whose guarantee compliments its operational history to improve warranty assurance.

2) Diverse satisfaction. The internet is much bigger than one review platform, solar companies often focus on one review website for the unsuspecting purchaser. Comparative reviews on alternative media streams suggest differently and provide greater insight, adding great weight to Perth’s best solar companies.

3) Review count of aligned platforms. Ignore our choice of reviewing websites. Find multiple platforms that your shortlist of best solar companies has in common—any two or three, but make sure they are the same website (substitute websites don’t qualify). Consistency is what you want to see. Hone in on inconsistency.

4) Locally based, as dealing with eastern state businesses (or foreign support agencies) could be more fun. Homegrown organisations are hands down the best solar companies in Perth. Local business gets you! Perth Solar Warehouse understands local needs and can better assist at times of support. The world is on a sustainable energy journey from 2025. You deserve local knowledge and experience for expansion options, when you need it. 

5) In-house installation options give customers the system execution assurance they desire. A close-knit solar installation company is more likely to receive regular product care and safety training. The ideal time to perform the job correctly provides no complications regarding installer to company warranty disputes.

5) Visual competency away from stock images (there is a contrast). A genuine solar company proud of its workmanship will display its results regularly through social media so prospective customers can understand what to expect towards an end result. Most won’t. There is a choice: proven aesthetics or the unknown.

6) A Goldilocks company. Not too big, where customers are simply another cosmic element. Not too small, where business stability (warranty certainty) varies. We’re just right as your future energy partner. A solar company invested in your results is personable and approachable, with a defined evolution.

Customer experience

Some solar companies have reviews. Others have experiences. Depth over time is important in this scenario. The volume of high-level experiences over time can act as a significant value for an informed buying decision. Over 1400 experiences on comparative platforms. Perth Solar Warehouse customer experiences spanning the last two decades:

Tip: Compare the best solar companies in Perth on low-review-count platforms (platforms with less than 50 reviews). Low-review-count platforms ensure a company doesn’t drown out the negativity on key targeted platforms with reviews that lack substance. A high volume of 0 to 5-word reviews isn’t an experience.

Manufacturer satisfaction

Manufacturers rely on dependable local solar companies to implement their products at ground level, regardless of an individual’s accreditations. SAA-accredited installers bounce around from business to business, often with little concern or regard for previous projects. Warranty concerns can often arise with complexity relying on an idividuals SAA-accreditation alone. Manfacturer-certified, industry-endorsed partners are the best solar companies Perth customers should seek out. These solar companies will most likely be more knowledgeable about a manufacturer’s recommended installation practices through required continuous professional development.

Perth Solar Warehouse’s manufacturer endorsements:

  • Tesla Premium Certified Installer 2024
  • Fronius Service Partner
  • SMA PowerUP Partner 2024
  • REC Certified Protrust Solar Professional 2024
  • Risen Energy Preferred (Gold) Partner
  • Jinko Approved Installer
  • Suntech Approved Installer
  • Aiko Approved Installer

Interest-free solar deals provide an opportunity for the energy savvy

Interest Free Solar Deal Perth WA

Interest-free solar deals are presented in various formats to suit a narrative that rarely becomes reality. That’s because you don’t live like a pre-empted calculation, no matter how many past electricity bills you have in your arsenal.

Contents

The argument towards interest-free solar is that you can use a combination of solar energy options to your advantage by replacing a portion of the electricity bill savings as a fortnightly payment towards solar power. The offer seems straightforward.

Scenario A: 🙂

  • You save X amount on energy costs with solar.
  • Use those savings to pay for solar, nothing out-of-pocket.

Almost a no-brainer, but it’s always wise to consider the alternative: You acquire an interest-free solar energy system, and your energy consumption misaligns with solar energy production…

Scenario B: ☹️

  • Your energy bill remains similar to before solar costs.
  • Household outgoings now include electricity from the grid costs + a solar repayment plan.

Scenario B will leave a bad taste in anyone’s mouth after investing in a household cost-reduction mechanism that increases total outgoings. However, homeowners can install a low-cost feature alongside a basic interest-free solar package to assist with a more likely Scenario. Tip: it isn’t a battery.

Is interest-free solar right for you?

  • Interest-free solar affects bill savings only through load-shifting
  • 40:60, the minimum energy consumption profile for solar-only systems

No matter how an interest-free solar package is presented, solar-only systems deliver reflective bill savings when you can consume as much solar power as is generated. Bill reduction works through load shifting in line with solar production. Load shifting is an industry term that encourages the shift of on-demand appliance (energy load) use to a more planned operation period that aligns with free energy from the sun.

Example: 

  • After dinner (night) dishwasher use can be substituted for morning operation when the sun rises for no-cost automated washing. 
  • An air conditioner operates from midday to regulate household temperature using thermal mass as an energy storage maechanism avoiding evening use and related energy expenses.

Results from an interest-free solar-only energy system without a battery and a negligible feed-in tariff begin at 40% day to 60% evening consumption. Improving this ratio impacts bill reduction, which is more likely to offset an interest-free solar repayment plan.

Exporting to the grid shouldn’t be a consideration. The Distributed Energy Buy-Back Scheme (DEBS/Synergy feed-in tariff) returns 2c per unit during peak generation hours and 10c in the dwindling parts of the day. A valuation that is likely continue its downward trend annually due to the lower value/excess energy available on the network at that time of day.

How to make it work

  • Add an energy consumption monitor to maximise savings

Ratios, consumption profiles, peak power, kW and kWh can become daunting, and we agree it’s too much to consider unthinkingly. From $390 on top of the base system cost, Perth Solar Warehouse recommends adding an energy consumption monitor to every solar-only system where provision is possible.

Unlike your [Western Power] electricity meter, a solar-connected energy consumption monitor sits in line with the property’s electricity meter or point of supply and is communicatively connected to the solar inverter. Delivering the data to visualise a property energy profile through reporting energy import and export information alongside standard feature production monitoring and service alerts. Actionable data is delivered in real-time through one energy app in more advanced technologies, removing guesswork associated with load shifting.

Comparing interest-free solar deals vs no solar

  • Self-generated power supplies improve energy security.

With the cost of energy consistently increasing over the previous decade and likely continuing annually, generating your energy from natural resources for the price of a payment plan over a limited period has merit. Interest-free solar assists broader market access by reducing adoption barriers if the cost is minimal upfront.

Application requirements

  • Low doc approval process for purchases under $20,000

Most solar companies use three prominent interest-free solar finance providers, who are often vendor-nominated, to facilitate customer payment terms and schedules. Brighte, Plenti and HUMM have a good track record among eligible customers and solar installation companies by satisfying customers through low documentation and vendors alike with a timely financing facility to reach a broader market where out-of-pocket costs could be an adoption barrier.

Documentation
Purpose
Personal Identification
Two forms of recognised identification (Driver’s licence, Medicare card, Passport etc).
Capacity to pay

Review: Sigenergy’s ‘SigenStor’ provides a competative advantage

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

Now and again, a solar energy product arrives in Australia, garnishing the attention of enthusiasts. With established leading brand names consistently innovating to stay ahead of each other, new technology must have a competitive advantage to stand out and earn market share. In 2025, Sigenergy’s SigenStor will disrupt established sustainable energy brands with one of the most innovative all-in-one solutions driven by the goal of improved energy self-sufficiency. Here’s how.

Contents

Key points

  • Designed on a software foundation
  • Ultra efficient DC coupled energy system: inverter, battery, EV charger
  • Bidirectional EV charging capabilities
  • Flexible and upgradable with ease
  • Improved energy storage affordability: Cost p/kWh

Built on a software-first foundation, Sigenergy’s Sigenestor is conveniently positioned to outpace many established sustainable energy technologies. Developing new energy hardware this decade from the ground up enables innovators to think outside the box regarding the technological evolution process. With modern user experience now in the palm of your hand, consider the potential of a product developed from a software-first perspective—opposed to hardware-first. Such a design removes legacy hardware limitations, assisting a streamlined adaptation to modern user expectations as they evolve. 

Even though existing energy technologies possess excellent monitoring and control software, limitations restrict the release of software/firmware updates required in an evolving landscape. Most manufacturers have one universal web application for their products, old and new. New updates must consider all ‘legacy’ hardware models, ensuring a stable user experience. The more expansive a product suite, the more diligent a software/firmware release must be. This level of consideration takes time.

Which to consider?

Installation professionals will adapt to an alternative concept. However, this new design benefits end-users and installers alike through a more deliverable and controlled design that is less susceptible to installation-influenced failure points while maintaining customisable design flexibility.

The beauty of Sigenergy’s product offering is in its simplicity. The foundations you choose depend on the power supply feeding your premises: single-phase or three-phase. Therefore, the foundation of the Sigenergy energy product range is the Sigen Energy Controller, which facilitates integration with expanded SigenStor energy system products. 

Insight: Competing manufacturers are expected to be in a race to follow a similar design concept of all-in-one energy system modularity.

SELECTION TIP: Energy Controller vs Hybrid Inverter

If choosing Sigenergy as part of an initial solar-only solution with the intention of expansion capabilities at a later date, the Sigen Hybrid Inverter is the ideal starting point. It has the same function as the Sigen Energy Controller, with accessories and firmware to suit a solo application. Use Sigen Energy Controller when combining with Sigen Battery from the start.

1.1. Sigen Energy Controller SP: Single-phase solar, battery and EV charging controller. Advanced all-in-one technology for the modern energy user. DC solar and DC battery (hybrid) to AC grid-tie or off-grid inverter, compatible with the DC-coupled SigenStor battery and DC-coupled Sigen EV charger module. TLDR: Select when integrating SigenStor Battery modules at the same time—single-phase power supplies.

1.2. Sigen Energy Controller TP: Three-phase power output solar, battery and EV charging controller. Advanced all-in-one technology for the modern energy user. DC solar and DC battery (hybrid) to AC grid-tie or off-grid inverter, compatible with the DC-coupled SigenStor battery and DC-coupled Sigenergy EV charger module. TLDR: Select when integrating SigenStor Battery modules at the same time—three-phase power supplies.

1.3. Sigen Hybrid Inverter SP: Single-phase power output solar, battery and EV charging controller. Advanced all-in-one technology for the modern energy user. DC solar and DC battery (hybrid) to AC grid-tie or off-grid inverter, compatible with the DC-coupled SigenStor battery and DC-coupled Sigen EV charger module. TLDR: Select when choosing a grid-tie solar-only option initially (batteries later)—single-phase power supplies.

1.4. Sigen Hybrid Inverter TP: Three-phase power output solar, battery and EV charging controller. Advanced all-in-one technology for the modern energy user. DC solar and DC battery (hybrid) to AC grid-tie or off-grid inverter, compatible with the DC-coupled SigenStor battery and DC-coupled Sigenergy EV charger module. TLDR: Select when choosing a grid-tie solar-only input option initially (batteries later)—three-phase power supplies.

All power class Sigen Energy Controller and Hybrid Inverter models (3 to 25 kW) are identical in dimensions. This standardised sizing allows seamless expansion capability with modular add-on components common with Sigenstor, regardless of rated output power class/phase supply.

The more harmony there is with self-generated energy and utilisation, the more electricity you save purchasing from the grid. Today, in terms of sustainable energy technology, there are two categorisations: a more disconnected solar energy system with physical wiring to connect disconnected componentry or an all-in-one, internally connected sustainable energy system.

The mySigen App is where the Sigenergy energy system comes together for energy visualisation and control. Purchase add-on hardware such as bidirectional EV charging and cross-compatible 5 and 8 kWh LiFePO4 (Lithium Iron phosphate) battery storage. Revolutionising versatility in an all-in-one sustainable energy solution, it would be fair to suggest that no two SigenStor neighbours are the same.

You use your power differently from your neighbour and deserve an ideal self-generated power supply to suit you, even if that’s in the form of initial affordability in the Sigen Hybrid Inverter with solar panels. Previously, more bespoke solutions were expensive, adding significant cost barriers for the mainstream. SigenStor proves that refined customisation is possible for mass appeal and uptake.

Which is ideal for you?

  • Determine if you have a single-phase or three-phase power supply.
  • Consider your average daily consumption (check energy bill).
  • Is the property suitable to accomodate a set number of solar panels to supply SigenStor?
  • If solar panels aren't an option, consider SigenStor for dynamic tariff utilisation, and superior DC EV fast charging with bidirectional capabilities.

Determine if your property has a single or 3-phase power supply. Once you know the power supply, it becomes easier to follow the downward Sigenergy SigenStor stream and gauge more accurate pricing for comparison. Following this, consider ‘Total daily energy consumption’ (kWh). Easiest located on your electricity bill.

Give this next step focused consideration for more refined system sizing. What portion of your daily energy use is day vs. night? (e.g., 40% day, 60% night). Knowing this ratio, choose an appropriately sized solar array to charge storage capacity for night-time consumption while meeting day-time energy consumption needs. Understand that different periods of the year will have various levels of self-sufficiency. Suppose SigenStor’s system requirements are initially under-sized. In that case, Sigenergy has developed the SigenStor system to be more accessible and cost-friendly, mitigating the requirement for elongated labour costs during the upgrade.

Perth Solar Warehouse recommends choosing a Sigen Energy Gateway and 8 kWh Sigen battery alongside your ideal Sigen Energy Controller as a foundational SigenStor consideration to help minimise system expansion costs if necessary.

Designed for a new generation of energy users, Sigenergy incorporates the unrivalled user experience most expect from 2025. Building advanced hardware to suit superior software, empowering users throughout an ever-changing energy landscape. But this isn’t just spin. Sigenergy’s global case studies are convincingly good in diverse global locations. Once in a decade, an energy product arises and shapes a new direction through superior design and user experience.

Guide: Solar rebate Perth & Bunbury region simplified (zone 3)

Sunrise over Perth City for Solar Rebate Perth WA

Exercise caution surrounding subsidy hype. Even though the zone 3 solar rebate Perth and Bunbury region customers can access isn’t a fixed rebate/subsidy, it’s always advisable to consider your options. Comprised of Small Technology Certificates (STCs), the value is subject to potential change daily. More recently, the spot price per certificate has remained relatively stable, affecting a steady total subsidy amount. Here is the need-to-know information (including amounts) when considering the solar rebate in 2025.

Contents

Related: The 2025 proposed WA solar battery rebate

The national STC solar rebate/subsidy differs from the proposed solar battery rebate announced on 22nd February 2025 and is an additional rebate with consistently evolving clarity. We’ve created a helpful guide to ensure Perth Solar Warehouse customers are first in the queue for the limited $328 million proposal. 

Guide: West Australian solar battery rebate & interest-free loan ›

The article below contains information about the Australian National STC (Small Technology Certificate) solar rebate Perth-based customers have access to. For up to date solar battery rebate details, use the above link.

How much solar rebate are you entitled to

The solar rebate Perth customers can access varies depending on system size (combined solar module generation capacity). Most typical residential subsidies start from $1,248 for a 3.9 kW solar system to $2080 for a 6.6 kW solar energy system. Subsidies increase for larger solar energy systems based on the ability to offset more significant carbon emissions. 10.5 kW solar systems enjoy a $3327 contribution to offset the cost, while a 13.2 kW system benefits from up to $4159.

As a traded component for offsetting carbon emissions, the solar rebate has the potential to fluctuate daily while degrading in annual blocks for the remaining 6 years of the preset target.

Even though spot value fluctuations have occurred in the past, it’s advisable to avoid rushing a buying decision based on subsidy value. Instead, ensure an informed buying decision as the fluctuations, and annual variances are minimal over a solar energy system’s life expectancy.

In the following content, understand how to calculate your precise solar subsidy and the amount you are entitled to depending on your ideal energy system size.

How the solar rebate works

Your new solar energy system is eligible for a nominated amount of certificates based on its ability to offset carbon emissions over the next 6 years. That’s right, you will produce clean, green energy, not just energy savings. Therefore, the Australian Government Clean Energy Regulator rewards you with a designated number of Small Technology Certificates (STCs) depending on your solar energy system size.

Your subsidy value is acquired by trading your Small Technology Certificates with big polluters who must purchase these clean energy certificates (STCs) to offset their carbon emissions towards net zero. Such complexities are often too much for most, including solar companies. Therefore, releasing the Small Technology Certificates for a point-of-sale discount at an agreed market rate is more manageable.

At the time of writing, $38 is considered a stable rate amongst most retailers, allowing for potential market fluctuations without consumer clawback in the event of change.6

On top of a point-of-sale discount (subsidy), most residential solar systems are eligible for a feed-in tariff through Synergy for excess energy exported to the grid. Learn more ›

Lock it in

Small Technology Certificate trading values have the potential to vary. July 2017, the spot value of STCs plummeted from $38 to $26 almost overnight due to an oversupply with insufficient purchasers. One year of STC value uncertainty followed. Since this and other instances, lost STC value recovery (clawback clause) is embedded into the terms and conditions of many installation contracts. In addition to the contract price, such could render the lost STC value payable by the customer after installation.

Perth Solar Warehouse monitors markets extensively and will never alter costs after a contract is signed unless agreed upon by all parties.

An adequate installation agreement should have the following clearly defined:

  • STC value, e.g. $38.
  • STC quantity, e.g. 55 certificates (as in 6.6 kW).
  • STC total value, e.g. $2,080 ($38 x 55 certificates).

When offered a point-of-sale discount as part of a solar package, you want the solar rebate to be precise and broken down into an easily calculable format.

How to calculate it

A formula for calculating the solar rebate exists, and here it is.

Array Combined Watts (Standard Test Conditions) x 1.382 x the current Small Technology Certificate multiplier of 7 years / 1000. The result is the maximum number of Small Technology Certificates eligible for your solar energy system.

Example: 6.6 kW Solar System

Solar Array Combined Watts (6600) x 1.382 x 6 (years) / 1000. The resulting number is the maximum STCs eligible.

(6660 x 1.382) x 6 / 1000 = 55.

Determining the amount of Small Technology Certificates (STCs) is 55 for a 6.6 kW system. Multiply this amount by the current market value of $38.

55 STCs x $38 = $2080.

Subsidy by system size expanded

For most, calculations are too time-consuming in a modern world full of fast information. It would be best if you had the figures to verify against. The most common solar rebate Perth residential homeowners can expect to receive based on a $38 STC value and using a 440 W solar panel variant for multiplication is as follows:

Array size
STC’s
Subsidy
3.9 kW
33
$1,248

The above combined Small Technology Certificate value is an example and subject to potential market fluctuations.

In all system sizes, the solar rebate Perth and Bunbury region customers can access provides a significant upfront saving on the cost of energy security. Considering the value of the subsidy is due to reduce each year, 2025 is an ideal time to invest in your energy future. Aim for a hassle-free transition to solar power.

We then used the Supply Charge per day and Cost per kWh unit information to provide a level of guidance for the next 10 years if staying on course. Of course, none of this is financial advice, so take it with a pinch of salt.

Perth’s population continues to grow and will continue to do so in the foreseeable future. As the population grows, energy generation and infrastructure costs increase to expand the grid. Reflected in a history of Synergy electricity rate increases in Perth and the South West of Western Australia.

History of Synergy electricity rates

The figures below represent annual Synergy’s Home Plan A1 Tariff rate information since 2014. In 2017, the Supply charge per day nearly doubled, yet the Cost per kWh unit rate remained the same as the previous year. 2020 was an unprecedented year with the COVID-19 pandemic, and Synergy electricity rates on the Home Plan A1 Tarriff were responsibly frozen.

Future bill potential

Using the previous decade’s Synergy electricity rates, which increased at an average of 2.7% p.a from 2014 to 2024 it’s possible to assume Synergy electricity rates in equal distance in time. Considering energy supply costs and electricity grid upkeep, a 10-year linear trend should be considered a best-case scenario. Converting the Home Plan A1 tariff to a bi-monthly bill value of 25 units (kWh) per day:

Likelihood of increases beyond average

2025 is an interesting year. Compounding geopolitical uncertainty affects wholesale energy prices regardless of extraction points. Western Australia is a state that’s part of a country with a policy to reduce carbon emissions from high-carbon-emitting power sources by 2050. Beyond emission reduction, increased generation points and ‘mix’ (various energy sources) will more likely stabilise Synergy electricity rate increases as opposed to a one-fuel grid supply more susceptible to global influence.

Here are the current global and local factors that directly influence Synergy’s electricity rates through supply chain and market values.

Inflation. After a more turbulent 24-month period, the downstream effects of inflation on consumable items are highly felt. Utilities are not immune to inflation.

East Coast (Australia) energy. Even if it’s a more variable market, factors affecting the east coast of Australia eventually filter through to Western Australia. Western Australia mines certain combustion fuel supplies, but local and global supply/demand affect wholesale prices.

Skilled wages: Australia has a general unemployment rate of around 4% and a higher-than-average deficit in skilled energy workers to upkeep and procure the current electricity network. Contributing to a downstream value currently at $1.13 per day supply charge and 31 cents per unit of energy consumed.

Russia and Ukraine. Although Russia doesn’t supply Western Australia with oil or gas, its 12% global share affects world wholesale energy prices, which form the composition of Western Australia’s energy mix. 

China and Taiwan. Should tensions between China and Taiwan escalate, the first effect on Australian supply chains will be costs and insurance variations for transport within the South China Sea. 

Emission reduction targets. Carbon-intensive energy generation for expanding populations doesn’t positively impact the environment. Achieving emission reduction targets is required for Australia to have a valued voice at the geopolitical table. Australia has a Net Zero international commitment.

In 2025, an energy mix on the grid is required to safeguard Synergy’s electricity rate certainty by reducing dependency on a single fuel source.

Improved lower cost energy options

In the same way it’s difficult to imagine a present without internal combustion vehicles, one hundred years ago, we transitioned from horse-drawn transportation systems. Energy generation from sustainable sources is the long-term global approach to achieving a sustaining balance of energy.

Solar power on home rooftops provides improved energy security by harnessing the daily rain of photons. With solar energy, it’s wise to think of it as water raining down on a roof. Avoid wasting energy down the drain (on the grid) and improve your energy security by adding a solar battery to store unused energy from the sun.

One step further on your electrification journey, add a solar-optimised EV charger to power your electric vehicle solely from the sun. Also take advantage of reduced energy supply tariffs, such as Synergy’s EV add-on tariff. According to required international emission reduction standards affecting most developed nations, Electric Vehicles are estimated to account for 60% of new car sales by 2030.

Review: Is a Fronius inverter worth the additional cost?

New Fronius Inverter (GEN24) on a concrete wall with a female technician checking the app

Many say yes, and some say no. But it’s 2025, and a decade of innovation has passed since the launch of the acclaimed Fronius snap-inverter range—an iconic inverter suite that catapulted Fronius’s success in Australia. With a vast improvement in all electronic products manufactured globally, an often confronting question arises when exploring a solar energy investment: “Is a Fronius inverter worth the additional expense?” The good news is that a more modern perspective exists to determine a Fronius inverter’s suitability and value. Consider the ecosystem.

Contents

Key points

  • Expanded energy ecosystem for future compatibilities.
  • GEN24 series a is the latest hybrid solar & battery inverter.
  • Automated manufacturing facility based in Wels, Austria.
  • 'DC power proficiency' since 1945 (Fronius welders).

The modern energy ecosystem is where energy control digitalises and comes together. Each dwelling within Australia is about to form its own over the coming decades. The useability and effectiveness of this energy ecosystem reflect the product selection along the journey. Consider the solar inverter the foundation of your new energy ecosystem.

With a good reputation reflected in a significant Australian market share, many consider incorporating a Fronius inverter as the foundation of a solar energy system an astute move. In 2025, an energy system is more than just solar panels and an inverter. It’s an ecosystem of solar-optimised energy expansion options, and additional consideration of the Fronius inverters’ associated peripherals should be considered at the same time.

Which to consider

Ensuring the ideal foundation for your new energy ecosystem means selecting the precise Fronius inverter. In most instances, the power supply to the premises defines your Fronius inverter model. Single-phase power supplies consider Primo-branded Fronius inverters. Three-phase dwellings are compatible with the broad range of the Fronius Symo inverter models, capable of increased power requirements.

Fronius Primo GEN24: Due to grid limitations, Perth, Western Australia (South West region), Western Power limits single-phase inverter sizes to no greater than 5 kW output. Therefore, the 5 kW Fronius Primo GEN24 is an ideal single-phase solution capable of handling up to 9.9 kW of solar panels when paired with a BYD Battery-Box (Premium HVS/HVM) DC-coupled battery. A handy trick if a 6.6 kW solar array oversizing is short of the total units (kWh) per day you require.

Fronius Symo GEN24: With the discontinuation of the Fronius Symo Snap-inverter range in 2024, the Fronius Symo GEN24 series is the evolution for three-phase residential energy. If you prefer increased battery connectivity options, the Symo GEN24 is your Fronius inverter of choice. Due to the often cumbersome nature of hybrid inverters, there is currently no official forecast of a power class greater than 10 kW.

Fronius Symo: The proven Fronius inverter for most three-phase power supplies greater than 10 kW. Fronius Symo inverters provide added field assurance with over a decade of field success in Australia. A solar-only model, the Symo retains an onboard display for localised production and state interpretations, making it an ideal solution for installation with limited internet connectivity. As with all Fronius inverters, AC-coupled batteries are compatible.

Cost Saving Tip

GEN24 or GEN24Plus version? Save your money. Unless the BYD Battery-Box is integrated simultaneously with the solar energy system, there are limited reasons to invest in a Fronius GEN24PLUS model initially. Converting the GEN24 (non-plus) model to a GEN24PLUS after installation is easy. It’s a (paid) firmware update activated within your Fronius Solar.web monitoring portal, referred to as FroniusUP. If implementing the BYD Battery-Box in the future, activate this feature. Doing so reduces the initial system cost and ensures no wasted capital if the battery isn’t required.

Fronius inverter warranty

Fronius inverters come with a 10-year (5+5 year upon activation) product warranty when purchased through an authorised Fronius Solutions Partner (FSP) such as Perth Solar Warehouse. There are two reasons for a 5+5 year warranty as opposed to a straight 10-year warranty out of the box.

Supply chain quality control: This attribute ensures that Fronius has the registered information of your device and the company that installed your system. With such safeguards in place, your warranty will be more serviceable, and most importantly, system uptime will be maximised over its serviceable life.

Regional differences: Shipped to some of the most globally diverse regions, Fronius inverters come factory standard with a 5-year international warranty. Australia’s mature, sustainable energy industry grants an additional 5-year warranty extension. Manufacturers must be confident that their installer network can provide a service capable of improving end-user experience and maintaining a strong brand reputation.

As with all warranty conditions, there is no warranty if the manufacturer’s installation guidelines aren’t met. A sound reminder that selecting an adequately manufacturer-trained service partner to perform the installation improves the warranty assurance of your Fronius inverter.

Review: Which Jinko Solar panels should you consider in 2025

Ultimate Jinko Solar Panels Guide Perth WA

A world-leading BNEF-Tier1 listed solar panel manufacturer by volume, Jinko Solar’s 2025 range of panels can easily be refined to a core few options for those seeking an advanced solar module at a competitive price. However, specific differentiators are likely to appeal to some and not others. We’re diving deeper and discovering which Jinko Solar panels you should consider in 2025 for a more informed, sustainable energy investment decision for your home.

Contents

Key points

  • N-Type solar panel options
  • PV Moduletech AAA-rated and BNEF Tier-1 manufacturer (bankability)
  • Multi-national automated manufacturing
  • Good affordability
  • Larger power classes are not a technology improvement

Compared to previous years, this year’s Jinko solar panels are more distinguishable under two primary categories: the Tiger Neo and the Tiger Pro series. For residential energy purchasers in Australia, smaller formats of the Jinko Tiger Neo (54 half-cell version) refine the selection to two solid options. Away from the marketing fluff of “bigger is better,” concentrate on the technical specifics (we’re here to help if needed) and ensure the most suitable Jinko solar panel selection for your home based on characteristics and features.

Rewinding things a fraction, Jinko commenced the decade with one of the most distinguished international sustainable energy awards, the European InterSolar 2019 innovation award. Since then, the Jinko solar panels installed in Australia have often had their industry-leading twist that sets a mainstream standard. 2025’s line-up of Jinko Solar panels looks set to continue with the N-Type TOPCon as the architecture of choice.

Which to consider

2025 is the year of the snake on the Chinese zodiac. But for Jinko, they will enjoy another year of the Tiger. However, the next step is to discern beyond power class—because bigger isn’t always better.

Efficiency is the simplest way. A solar panel rated at a greater power output (475 or 510 W) with an efficiency of 20-22.5% is a larger solar panel occupying the same surface area on the roof as their lower Watt (440W) counterparts of 20-22.5% efficiency to make up the system size: 6.6, 10, 13 kW etc. In a world of marketing hype and sales tactics, you must consider alternative differentiators for your ideal sustainable energy solution. These Jinko Solar panels are the optimal panel class in 2025, away from potentially misleading hype, while maximising your energy systems performance and solar subsidy without batteries.

If you genuinely want a high-power output module, Jinko solar panels with greater power output exist. However, these aren’t the models you’ll want to consider for a residential solar installation due to mismatched electrical characteristics that are better suited for commercial and utility-scale solar inverters. All Jinko solar panels available in 2025 are close equivalents of each other, with the overall variation being dimensions, equaling weight for a more simplified comparison scope.

The Jinko Solar panels below ensure the perfect system balance for maximum oversizing and subsidy allocation for most small-scale residential and light commercial buildings in Australia.

Residential suitability: (order) Most ideal to least.

1. Jinko Tiger Neo Bifacial Dual-Glass (440 W): It’s the streamlined all-black, dual-glass reinforced counterpart of Jinko’s highest-selling module in Australia (the Tiger Neo). Jinko’s Tiger Neo Bifacial now reaches mass market affordability with added benefits. This Jinko solar panel comprises dual-glass construction plus bifacial module architecture for a little extra kick (it absorbs light from the front and rear surfaces of the solar panel). However, don’t expect significant gains without the albedo effect in full effect—mounted flat on your roof. If you’re seeking an improved aesthetic appeal and the most significant technology attributes from a particular Jinko Solar panel in 2025, the Neo Bifacial is one of their finest. -0.28%/°C temperature coefficient further defines this module from the pack.

2. Jinko Tiger Neo 54HL4 (440 W): Is the most popular model by units sold in Australia, an ultimate all-rounder. Jinko’s Tiger Neo base model solar panel offers outstanding cost attributes while being delivered by one of the world’s most bankable solar panel manufacturers for improved warranty assurance. With a matching efficiency (22%) with most other models in their fleet plus an assisted -0.29%/°C temperature coefficient, purchasers can enjoy sound generation in temperatures above 25°C. The reduced format dimensions of the Jinko Tiger Neo 440W 54-cell solar panel make it one of the most accommodating Jinko Tiger Neo models for residential rooftops. More than 2 million 440W Jinko Neo solar panels harvest Australian sunlight daily.

3. Jinko Tiger Neo 60HL4 (475/510 W): When a better option exists in the Neo 54HL4, avoid using the inflated Neo 60HL4 variant unless necessary. Jinko’s oldest model in the fleet supports the most significant overall dimensions—the Tiger Neo 60HL4 launched in 2021 as their flagship N-Type TOPCon solar panel for commercial-scale projects. At over 24 kg, it becomes more contentious around expansion and maintenance capabilities. The Jinko 475W (soon to be 510W) Tiger Neo was once the most reduced format version in the Neo range, with a commercial target market. It is the ideal multiplier for small-scale projects to maximise subsidy potential and the ultimate array for inverter oversizing. Remain cautious of salespeople promoting this as Jinko’s best solar panel because of its higher power class.

4. Jinko Tiger Neo (+570 W): Jinko Tiger Neo models greater than 570W aren’t suitable for residential installations in Australia due to size, weight and electrical characteristics.

5. Jinko Tiger Pro (+550W): The Jinko Tiger Pro is now only available in +550W models. Similar to the Jinko Tiger Neo 570W+, its size, weight, and electrical characteristics are not suitable for residential installations in Australia.

What is the warranty

The warranty between Jinko Solar panel models is more straightforward when comparing residential models in Australia. N-type (negatively charged) TOPCon Jinko Solar panels enjoy the most significant 25/30 warranty due to a module architecture with the likelihood of reduced degradation over the lifespan. Positively charged Jinko solar panels (P-type) in the form of Tiger Pro possess a reduced format product and performance warranty that is more likely to suit an industry-backed project’s intended lifespan.

Where are they made

Listed on the New York Stock Exchange (NYSE: JKS) and a Silicon Modules Super League member, Jinko operates a broad network of manufacturing plants internationally (China and U.S.A). However, the Jinko solar panels all Australian customers receive come from Jinko’s automated manufacturing facilities in China.

As manufacturing modules are only one process element, Jinko solar cell manufacturing occurs in Jinko plants across China, Vietnam and Malaysia.

A sign of global progress ahead of the manufacturing curve. In 2019, Jinko began manufacturing solar modules from a newly constructed $50 million, 400-megawatt plant in Jacksonville, Florida (USA). They have since been awarded a local grant and the ability to upgrade the facility by another $52 million.

With a view to increase their current 70% market share in the Middle-East. From 2026, Jinko Solar’s global footprint will continue with a newly constructed 10-gigawatt manufacturing plant. Further defining a Middle Eastern market power play with a significant manufacturing footprint out of Saudi Arabia.

What do they cost

Expect good value for the efficiencies available. Solar system prices incorporating Jinko solar panels will vary depending on module model selection, inverter selection, battery selection (if required) and other installation specifics. After the current zone 3 STC subsidy (Perth & Bunbury region), the average costs for a Jinko solar energy system (without batteries):

Which is ideal for you

If you’re seeking an ultra-high-performing and warranted long-term investment in the latest cell technology, consider the Tiger Neo 54HL4 range of Jinko solar panels. These are best suited to residential rooftops and technician safety. With an increased footprint and less-standard electrical characteristics, these larger Jinko solar panels may prove more difficult to maintain or expand capabilities in the future. Leave the Neo 60HL4 models for commercial-grade rooftops that can better support the personal capabilities, increased dimensions and centralised weight, not your home.

Thinking about visual aesthetics? the Tiger Neo Bificial, with the same performance characteristics and power output as the Jinko Tiger Neo 54HL4, combined with all-black mounting hardware, offers a superior streamlined appeal, while generating high power output in more adverse conditions.
