Interest-free solar and battery: how the WA Government’s $10,000 loan changes the calculation

The interest-free solar conversation used to begin and end with private finance providers — Brighte, Plenti, HUMM and a repayment plan you arranged through your installer. That model still exists, but it’s no longer the most compelling option for eligible Western Australian households.

Since 1 July 2025, the WA Residential Battery Scheme has included an optional no-interest loan of up to $10,000, administered by Plenti, as part of the state government’s battery uptake program. For households that qualify, this is a structurally different proposition to a vendor-arranged finance product and it warrants its own analysis.

The WA Residential Battery Scheme delivers two financial benefits that can be combined:

The rebate is calculated per kWh of usable battery capacity, capped at 10 kWh:

This rebate stacks with the federal Cheaper Home Batteries Program — a separate federal initiative that delivers approximately a 30% upfront discount on eligible batteries (for usable capacity between 5 kWh and 100 kWh, claimable on the first 50 kWh). The combined effect can meaningfully reduce the installed cost before financing is even considered.

Loan Amount

Term

Interest

Administered by

Household gross annual income must be under $210,000. Credit assessment applies.

The loan can be used to cover the battery and related equipment, including inverters and solar panels, where installed as part of a battery package under the scheme.

💡 Important: Participation in a Virtual Power Plant (VPP) is mandatory to access the rebate and loan. The VPP agreement period is two years, after which households can opt out.

The same honest question that applied to private interest-free solar finance applies here — perhaps more so, because the rebate and loan together are more likely to produce a genuine net benefit than a solar-only repayment plan ever was.

The original challenge with solar-only interest-free deals was misalignment between generation and consumption. Solar produces during the day; most households consume energy in the morning and evening. Without a battery, bill savings depend almost entirely on how much daytime load you can shift — an effort that requires behavioural change and, ideally, a consumption monitor to guide decisions.

A battery changes that dynamic. It captures daytime solar generation and makes it available after sundown, when household demand typically peaks and grid energy costs the most. In the Synergy area, the DEBS export rate during peak hours (3pm-9pm) is 10c/kWh — a fraction of what you pay to import at the same time. A battery earning you avoided imports is almost always more valuable than exporting to the grid at 10c and buying back at the retail rate.

This is why the WA scheme’s structure makes sense for many households: it finances the component — a battery — that most directly closes the gap between what solar produces and what you actually save.

State financing doesn’t change the physics of a solar-battery system, and the consumption profile logic remains valid.

Load shifting still improves outcomes. Running your dishwasher in the morning rather than after dinner, pre-cooling your home during midday solar production, and timing high-draw appliances to avoid evening peak periods all reduce how much you draw from the battery (and the grid) during expensive hours.

An energy consumption monitor — from around $390 added to the system — remains one of the highest-value additions to any solar installation. It puts generation, import, and export data in one place, replacing guesswork with actionable information. Perth Solar Warehouse recommends this addition wherever provision allows.

The Synergy Midday Saver tariff is also worth understanding if you’re evaluating load management options, as it offers the lowest cost-per-kWh during daytime hours for eligible customers.

Perth Solar Warehouse, operating under the PSW Energy brand, is listed by Plenti as an accredited WA Residential Battery Scheme vendor in the Synergy service area. Homeowners don’t lodge rebate applications directly — accredited vendors handle this through the scheme’s approved channel.

Confirm your eligibility: Synergy or Horizon Power account, residential property, new battery with at least 5 kWh usable capacity, willingness to join a VPP. For the loan, household gross income under $210,000.
Request a quote from Perth Solar Warehouse: Note whether you're considering the no-interest loan. We'll confirm approved product combinations and itemise the rebate separately in your quote.
Loan application (if applicable): Plenti will contact you to complete income verification and credit assessment. Have your most recent tax return accessible — scheme guidance references this — for income verification.
Installation and VPP onboarding: Timing constraints apply once approval is confirmed. Book installation promptly — conditional approval is not open-ended.

The scheme is funded for up to 100,000 rebates. Availability is finite.

EUPD Research Top Installer Awards 2024 and a Digital Revolution in Solar

EUPD Research Top Installer Awards 2024 presentation banner (left to right): Daniel Fuchs, Nicole Bilman and Derek McKercher holding the EUPD Installer Award 2024 shield

The vibrant atmosphere of Melbourne’s Cargo Hall Southbank recently played host to the 2024 EUPD Research Top Installer Awards Australia. Amidst industry leaders and innovators, Perth Solar Warehouse once again claimed a top spot, marking a second consecutive year as an award recipient. This achievement underscores a commitment to customer satisfaction, quality installations, and innovative solutions in the Australian solar market. The awards ceremony highlighted Perth Solar Warehouse’s commitment to setting the benchmark for innovation and excellence in the industry.

EUPD Research, a globally respected authority in market research, employs a meticulous approach to identify top installers. Their methodology goes beyond simple sales figures, delving into the heart of customer experience. By combining customer satisfaction surveys with installation volume data, EUPD ensures that awardees are not just successful installers, but trusted partners in their customers’ solar journey.

For Perth Solar Warehouse, this recognition powerfully validates a unique approach to the market through a pioneering digitally enhanced buying experience.

Perth Solar Warehouse understands that navigating the world of solar can be daunting for many homeowners. The answer? A cutting-edge digital platform that simplifies the entire process, making it more transparent, convenient, and customer-centric. This innovative approach has resonated with customers, contributing significantly to high satisfaction ratings and, ultimately, EUPD Research Top Installer Award 2024 recognition.

Needing an in-home consultation to quote a modern solar energy system accurately is a myth in 2024. In 2010, solar panels were more expensive, and there was a lack of accurate design software. Therefore, precise sizing and a more consultive process for customer needs were valid (today, in-home ‘consultants’ don’t even measure from the on roof – they’re there to sell you). With most system sizes now standardised and spare time more elusive than ever, the need to schedule on-site quotes can be more of a hindrance for the astute shopper seeking a proven solution.

One step further, we can improve value through digitalisation. Sales consultations are rarely free, and the cost (commission) is often embedded in an inflated price for the end user. If a remote site assessment proves inconclusive, a Perth Solar Warehouse technician conducts a site review based on a customer’s preferred system. Most importantly, the quoted/contracted price is always the final price, earning Perth Solar Warehouse a strong community and local trust for over a decade.

Growing consumer appeal:

Transparency: Customers gain access to clear and detailed information about products, pricing, and installation processes, eliminating any ambiguity and fostering trust.
Convenience: The entire journey, from initial inquiry to system design and installation schedule, can be managed online, saving customers valuable time and effort.
Personalised Solutions: The digital platform allows customers to explore various options and customise their solar systems to perfectly match their energy needs and budget.
High-Quality Outcomes: By streamlining the backend process and ensuring clear communication, Perth Solar Warehouse minimises potential errors and provides a smooth and efficient installation experience.

This commitment to a seamless digital experience aligns perfectly with the values recognised by the EUPD Top Installer award. By prioritising customer satisfaction and embracing innovation, Perth Solar Warehouse is meeting the demands of today’s tech-savvy consumers and setting a new standard for the industry.

Reduce your electricity bill: Synergy’s Midday Saver tariff + battery

Tesla Powerwal 3 pictured on the outside of a suburban Australian home identifying how alone a battery alone (without solar panels) can influence bills savings from the Synergy Midday Saver Tariff in Perth and Bunbury region Western Australia

Solar panels not included. Many homes in the greater Perth region of Western Australia can’t enjoy the benefits of solar panels due to property incompatibilities (shade, available surface area, etc.) yet still seek to earn greater energy security while reducing their electricity bills. Fortunately, solar energy is available on the grid during peak daylight hours and it’s cheap.

It is so abundant that Synergy is offering the cost of electricity during peak solar production periods at a quarter (8.4050 cents/kWh) of the Home Plan A1 tariff price. Here’s how you can reduce your bills by combining only a home battery system and the Synergy Midday Saver tariff.

A modern energy grid in one paragraph: The decentralisation of energy networks provides greater energy security for users and expanding populations, as they are less subjected to singular supply interruptions. Alongside decentralisation, variable fuel sources offer extra protection from potential supply market wholesale cost volatility. Perhaps even complication, but we’ve never had a more stable grid. Welcome to Western Power’s South West Interconnected System (SWIS for short), also known as ‘The Grid’, where Synergy is the local retailer.

Now, consider that the Western Power grid plays host to an energy market. Daily, the most affordable energy supplied at a nominated period takes preference to satisfy the network’s requirements. In Perth, there is an oversupply of solar energy between 9 am and 3 pm, enticing heavy day-time energy users with a sweeter deal.

Image: Daily solar energy yield between 9 am to 3 pm peak periods.

Quick Tip 1: Load shift when choosing the Synergy Midday Saver tariff, shift programmable appliance use between 9 am and 3 pm. Consider the following appliances: dishwasher, washing machine, dryer, e-mobility charging, pool pump, air conditioner (pre-conditioning), etc., to operate on cheaper grid-supplied solar energy at 8.4050 cents/kWh.

Quick Tip 2: Add a suitable battery to bridge the more costly 3 to 9pm ‘Peak’ period. Suitability depends on individual energy use. Tesla has almost mathed the ideal battery size for most homeowners during this period at 13.5 kWh (so much so that it didn’t change between models: Powerwall 2 vs 3). Many other batteries are either similar in energy density or more modular to achieve an ideal level of energy security. Cost per kWh is where battery customers in this segment must focus.

Sarah lives in Perth and is on the Synergy Midday Saver tariff. By knowing how to load shift certain appliances towards cheaper energy, Sarah now has enough energy storage in reserve to ensure she can clear the more expensive ‘Peak’ period. Sarah has a Tesla Powerwall 3 with a usable capacity of 13.5 kWh installed in her home, but she does not have solar panels.

Midday Saver Tariff Rates:

Peak (3 pm – 9 pm): 52.5313 cents/kWh
Off-Peak (9 pm – 9 am): 23.1138 cents/kWh
Super Off-Peak (9 am – 3 pm): 8.4050 cents/kWh

Scenario Calculations:

Charging the Powerwall: Sarah decides to fully charge her Powerwall during the Super Off-Peak period, 9 am to 3 pm.

Energy required: 13.5 kWh

Cost to charge: 13.5 kWh x 8.4050 cents/kWh = $1.134

Using the Powerwall: Sarah uses the entire stored energy in the Powerwall during the Peak period (3 pm to 9 pm) to power her home appliances.

Energy used: 13.5 kWh

Cost avoided during Peak: 13.5 kWh x 52.5313 cents/kWh = $7.054

Net Savings: Calculate the overall savings by subtracting the cost to charge the Powerwall and the daily supply charge from the cost avoided during peak hours.

Net savings: $7.054 – $1.134 – $1.2608 = $4.659

It’s important to note that the daily supply charge of the Synergy Midday Saver tariff is approximately 13c more per day than the Home Plan A1 Tariff. To consider this difference, subtract 13c from the $4.659 saved daily.

$4.659 – $0.13 = $4.53 savings per day

In this scenario, even without solar panels, Sarah is able to save $4.53 by strategically charging her Powerwall during Super Off-Peak hours and utilising the stored energy during Peak hours. This demonstrates how a home battery can be leveraged to optimise energy costs even for those without solar generation.

Additional benefits of the Synergy Midday Saver tariff are the reduced Off-Peak rates (9 pm to 9 am) rates of 23.1138c per kWh off-peak energy cost (vs Home Plan A1 Tariff: 31.5823c per kWh). Consider this an improved base load power supply cost for 24/7 appliances such as refrigerators, freezers, after-hours air conditioning use (if required), fans, and appliances on stand-by mode.

Additional Considerations:

The actual savings may vary depending on the household’s energy consumption patterns and the specific appliance use during different tariff periods.
It’s important to analyse your energy usage and tariff rates to determine if a home battery would be a cost-effective solution for your situation.
Daily supply charges vary between different Synergy tariffs.
Tariff rates change anually.

Image: Synergy Midday Saver tariff provides an energy-saving opportunity for those without solar panels.

Synergy is a retail energy business, so the numbers must provide a level of profitability, regardless of the energy supplied from the grid. Below is a brief comparison of the three main tariffs available in 2024/25:

Home Plan (A1)

Your energy consumption knowledge: Easy

Supply charge (daily): $1.1322
All day/night: 0.315823 cents/kWh

The set-and-forget ‘easy’ Synergy electricity rate more appealing to users who choose to be less concerned about how and when they use energy. The rates within the Synergy Home Plan (A1) tariff ensure a mid-range cost of electricity. How much you pay depends on your ‘anytime’ energy consumption.

Bill reduction potential: N/A. Best for those who want to operate energy anytime and not worry about variable cost benefit options.

Midday Saver

Your energy consumption knowledge: Intermediate

Supply charge (daily): $1.2607
Peak (3pm – 9pm): 52.5313 cents/kWh
Off-Peak (9pm – 9am): 23.1138 cents/kWh
Super Off-Peak (9am – 3pm): 8.4050 cents/kWh

The Synergy Midday Saver tariff is ideal for users who have a finely tuned operational energy sense. You know what appliances you’re using and when you’re using them, and mastering energy bill reduction by optimising habits in line with low-cost energy.

Bill reduction potential: Improved through greater energy market exposure and the ability to capitalise on the opportune time. Strongly consider home energy storage to bridge peak charge costs.

EV Add On

Your energy consumption knowledge: Advanced

Supply charge (daily): $1.2607
Peak (3pm – 9pm): 52.5313 cents/kWh
Off-Peak (6am – 9am / 9pm to 11pm): 23.1138 cents/kWh
Super Off-Peak (9am – 3pm): 8.4050 cents/kWh
Overnight electricity charge (11pm to 6am): 18.9113 cents/kWh

The EV Add-On tariff is effectively the same as the Synergy Midday Saver tariff except for one improved cost layer: the Overnight electricity charge between 11pm and 6am (but you must own an electric vehicle). This can effectively be used to top up the home battery alongside an electric vehicle ready for use with the morning’s energy use. EV add-on should only be considered for those with an advanced knowledge of how and when precisely to operate certain loads.

Bill reduction potential: Varied. Primarily, you’re now aiming to supplement petrol energy at a lower cost/km travelled for your vehicle and prepared to schedule home electricity consumption on an advanced level. So, the costs you save through optimising appliance use will host an EV charging component (approx. 10 kWh daily). But if you’re on this plan, you know what you’re doing. Higher or similar Synergy bills are likely, but overall energy spending (Average household energy profile: electric, natural gas, oil/petrochemical) will be reduced if monitored and aligned with low-cost inputs. Strongly consider bidirectional EV charging capabilities or home energy storage to bridge Peak charge costs.

Return on investment calculations are always subjective yet provide a level of insight into the approximate timeframe you are likely to see your initial investment is recovered in savings and the point at a point of where your investment makes money. However, when it comes to batteries, many focus on energy savings alone at the current rate and neglect alternative benefits that may improve calculations:

Future ‘Peak’ rate increase protection
Inflationary protection
Additional energy security, such as blackout protection
Advanced operational features including energy profiling and solar optimisation [with solar]

If you’re using the Synergy Midday Saver tariff with a battery and no solar the return on investment in energy savings alone is less than ten years in current rate energy savings. These added benefit may well improve ROI calculations depending on the individual scenario and total installed battery cost.

Midday Saver with 1 x Battery [no solar]

However, we can assume a scenario with base-level costs and total daily battery cycling with the intention of bridging the Peak period rates at the current tariff rate, which historically increases at approximately 2.5 -3% p/a for fossil fuel-generated energy.

Scenario A: Sarah buys a Tesla Powerwall 3 installed from Perth Solar Warehouse.

Purchase price: $15,990 [current prices]

Daily energy savings: $4.53

Calculated ROI: $15,990 ÷ 4.53 = 3530 days/ 9.7 years

Even without solar panels, Sarah can now power her home from low-cost solar energy plus protect herself from blackouts and future price increases of fossil-fuel-generated energy. With Tesla Powerwall 3’s software and smart tariff utilisation features, she has the ability to improve load shifting to low-cost power hours, further expediting her return on investment.

Midday Saver with 2 x Batteries [no solar]

Sarah draws more power than most homes between 3 p.m. and 9 p.m., so she decides to double down on her investment in a more suitable battery capacity of 27 kWh. Considering the initial battery price factors a major installation component cost, additional capacity is far simpler to install affecting an improved addition capacity cost.

Scenario A: Sarah buys 2 x Tesla Powerwall 3’s installed from Perth Solar Warehouse totalling 27 kWh of power reserve.

Purchase price: $15,990 + $13990 = $29,980

Daily energy savings: $9.06

Calculated ROI: $29,980 ÷ 9.06 = 3309 days/ 9 years

Increasing her energy storage capacity improves Sarah’s initial return on investment calculations while contributing to more sustainable energy sources with added energy security benefits.

Using the Synergy Midday Saver tariff blindly and unprepared will not reduce your electricity bills. However, if you can better optimise energy consumption alongside a battery to skip the more costly Peak period, where opportunities exist with improved energy independence and security.

Silicon wafer prices rise, wholesale module prices likely to follow

Advanced stage of silicon wafers within the solar module manufacturing process, under a red light with an engineer observing through a processing window to identify that silicon wafer prices have stabilised and and downstream effect to overall module costs is coming.

The wholesale downward trend of solar module prices on a cost-per-watt level had to end eventually, and the tide may have just turned, citing an August increase in silicon wafer prices by LONGi and TCL Zhonghuan—two large manufacturers of silicon wafers used in solar panels. This comes as an overdue respite for solar module manufacturers seeking a return to profitability in 2025. So, what does this mean for the future solar energy landscape locally?

LONGi and TCL Zhonghuan raise silicon wafer prices, reports PV Magazine
Improved international solar panel demand
Likely increase 'cost p/Watt' of record low wholesale solar panel prices
Reduced subsidy value and increased panel prices will affect system affordability (Cost per/Watt) in 2025

Like all global markets, the solar energy market has endured an interesting period, with continued ripples affecting purchasing certainty at scale: COVID-19, the Russia-Ukraine conflict, US Manufacturing laws, and the overall complex international landscape, which affect supply chains in a start-stop, start-stop, start-again motion.

The recent increase in silicon wafer prices is a reprieve for manufacturers forced to sell excess stock below the cost of manufacture. Demand for silicon wafers is a sign that the previous market saturation has cleared, and pressure for increased production of the fundamental component used to build solar panels has returned internationally among a broader segment of solar panel manufacturers. Interestingly, a turn towards higher solar module prices is good for purchasers.

Image: Whole cell Silicon wafer used in solar panel construction.

Considering the new solar panel warranty is at least 25 years for residential rooftop solar panels, system owners need a manufacturer that is more likely to be around in 25 years. When writing, most solar panels at wholesale in Australia are close to or below the manufacturer’s production cost. All businesses have a limited window to exist without margin. An increase in silicon wafer prices signals that many remaining manufacturers have more likely weathered the loss and resumed taking new orders.

Forecast: Leading manufacturers will return to profitability in 2025/26 as demand firms through more countries adopt a more carbon-neutral future. Smaller module manufacturers will experience an enduring period of uncertainty.

1. The Small Technology Certificate (STC) value used to subsidise solar energy system costs in Australia will be reduced from the 1st of January 2025. Example: A $38 Small Technology Certificate value and 440W solar panel for multiplication of the most common system sizes in the Perth and Bunbury region of Western Australia:

3.9 kW

3.9 kW = $1,456 – 2024 installation
3.9 kW = $1,248 – 2025 installation

6.6 kW

6.6 kW = $2,426 – 2024 installation
6.6kW = $2,088 – 2025 installation

10.5 kW

10.5 kW = $3,882 – 2024 installation
10.5 kW = $3,327 – 2025 installation

13.2 kW

13.2 kW = $4,852 – 2024 installation
13.2 kW = $ 4,159 – 2025 installation

19.8 kW

19.8 kW = $7,279 – 2024 installation
19.8 kW = $6,239 – 2025 installation

39.6 kW

39.6 kW = $14,577 – 2024 installation
39.6 kW = $12,478 – 2025 installation

99.8 kW

99.8 kW = $36,717 – 2024 installation
99.8 kW = $30,908 – 2025 installation

2. Should silicon wafer prices continue to increase, downstream newly produced module costs will increase. Silicon wafers are a fundamental component of the greater global demand for improved sustainable energy resources in areas with abundant sunlight than alternative sustainable energy sources.

As the August 2024 PV Magazine article Chinese PV Industry Brief: Longi, TCL Zhonghuan Raise Silicon Wafer Prices points out, major silicon wafer manufacturers Longi and TCL Zhonghuan have recently increased their prices. This is due to several factors, including rising polysilicon prices and strong demand for solar panels. Price increases are expected to continue, which could lead to higher solar panel costs depending on alternative local market factors.

Image: Raw material Poly Silicon rock used in solar panel construction.

Like any market saturation, prices fall as the demand to move excess stock becomes more critical. Astute investors identify opportunities where rebound potential exists. With record-low wholesale cost p/Watt module prices and improved global demand for the fundamental component required for manufacturing solar panels, it may well be that a more opportunistic moment for a solar energy investment exists today.

Perth Solar Warehouse is committed to providing our customers with the latest information on the solar industry. If you are looking for local advice on a solar energy system that matches your needs without overcomplication, we can assist.
