Solar Financing in Perth: How to Get Solar with $0 Upfront in 2026
The upfront cost of solar is the single biggest reason Perth homeowners delay going solar. A quality 6.6kW system runs between $5,000 and $6,000 after the federal STC rebate, and adding a battery pushes that figure to $10,000 or more. For most households, that’s a significant cheque to write, even when the payback period is just 3 to 4 years.
Here’s what most people don’t realise: in 2026, the combination of government rebates, no-interest loans, and installer financing means many Perth homeowners can get solar and a battery installed for $0 out of pocket today. The savings start from day one, and the loan repayments are typically less than the reduction in your power bill.
This guide breaks down exactly what’s available, how the schemes stack together, and what real-world costs look like for a typical Perth household.
Key takeaway: The WA Residential Battery Scheme offers up to $10,000 in no-interest loans via Plenti, stackable with rebates worth $5,000 to $7,500. When combined with installer financing, a $0 upfront solar and battery installation is genuinely achievable for most Perth homeowners in 2026.
The WA Residential Battery Scheme: What It Actually Covers
The WA Residential Battery Scheme is the most significant solar financing opportunity available to Perth homeowners right now. Backed by a $337 million government commitment, the scheme provides both upfront rebates and no-interest loans to eligible households on the Synergy and Horizon Power networks.
The No-Interest Loan
The loan component is the headline feature. Eligible households can borrow between $2,001 and $10,000 at 0% interest, with repayment terms of 3 to 10 years. There are no early repayment fees, and the only penalty is a capped late fee of $10 per week (maximum $120 per year) if payments are missed.
Critically, the loan can be used for:
- Battery storage systems
- New solar panels (when bundled with a battery)
- Hybrid inverters and upgraded equipment
- Combined solar and battery packages
This means the loan isn’t just for the battery. If you’re going solar and battery together, the entire package can be financed through the scheme.
Eligibility at a Glance
| Requirement | Detail |
|---|---|
| Location | WA Synergy or Horizon Power customer |
| Income | Household gross income under $210,000 |
| Age | 18+ and permanent Australian resident |
| Battery size | Minimum 5kWh usable capacity |
| Installation date | New or replacement batteries from 1 July 2025 onwards |
| Loan amount | $2,001 to $10,000 |
| Credit check | Required (administered by Plenti) |
One important note: you must join a Virtual Power Plant (VPP) to access the rebate. The VPP agreement runs for two years, after which you can opt out at any time.
How the Rebates Stack
The scheme’s rebate component sits on top of the federal Cheaper Home Batteries Program, and the combined savings are substantial:
- Synergy customers: Up to $5,000 combined rebate on a 10kWh battery
- Horizon Power customers: Up to $7,500 combined rebate on a 10kWh battery
The rebate is delivered as an upfront point-of-sale discount applied by your approved installer. You never see the money; it simply reduces what you owe on the day of installation. The WA Government has allocated 100,000 rebates statewide, with the scheme expected to run until approximately 2027 or until allocations are exhausted.
The bottom line: Apply before allocations run out. This scheme won’t be available indefinitely.
What Does $0 Upfront Actually Look Like? Real Cost Scenarios
The phrase “$0 upfront” gets thrown around a lot. Here’s what it looks like in real dollar terms for Perth households in 2026, using current market pricing.
Scenario 1: Solar Only (6.6kW System)
A typical 6.6kW solar system in Perth costs between $5,000 and $6,000 after the federal STC rebate has already been deducted. This is the most common residential system size and generates around 28 to 30kWh per day.
| Item | Cost |
|---|---|
| 6.6kW system (after STC rebate) | $5,500 (midpoint estimate) |
| Financed via Talk Energy easy financing | $0 upfront |
| Estimated annual bill savings | $1,200 to $1,800 |
| Typical payback period | 3 to 4 years |
For solar-only installations, Talk Energy’s fast financing option means you can get panels on your roof without touching your savings.
Scenario 2: Solar + Battery Bundle (6.6kW + 10kWh Battery, Synergy Customer)
This is where the WA scheme delivers its biggest impact. A combined solar and battery system typically costs $13,000 to $15,000 before incentives.
| Item | Amount |
|---|---|
| System cost (before incentives) | ~$14,000 |
| Less: WA Battery Rebate (Synergy) | -$1,300 |
| Less: Federal Cheaper Home Batteries rebate | -$3,700 |
| Subtotal after rebates | ~$9,000 |
| WA no-interest loan (covers remainder) | Up to $10,000 |
| Out-of-pocket upfront | $0 |
| Loan repayment (10-year term) | ~$75/month |
| Estimated monthly bill reduction | $150 to $250 |
The loan repayments are comfortably covered by the savings on your electricity bill. In most cases, you’re cash-flow positive from month one.
Scenario 3: Solar + Battery Bundle (Horizon Power Customer)
Horizon Power customers receive a significantly higher rebate, making the numbers even more compelling.
| Item | Amount |
|---|---|
| System cost (before incentives) | ~$14,000 |
| Less: WA Battery Rebate (Horizon Power) | -$3,800 |
| Less: Federal Cheaper Home Batteries rebate | -$3,700 |
| Subtotal after rebates | ~$6,500 |
| WA no-interest loan | Up to $10,000 |
| Out-of-pocket upfront | $0 |
| Remaining loan balance | ~$6,500 |
| Loan repayment (10-year term) | ~$54/month |

How to Apply: The Step-by-Step Process
One of the most misunderstood aspects of the WA Residential Battery Scheme is how applications work. You do not apply directly to the government. Your approved installer handles the entire application process on your behalf through Plenti, the scheme’s licensed administrator.
Here’s how the process works from start to finish:
- Confirm your eligibility. Check that you’re a Synergy or Horizon Power customer, your household income is under $210,000, and you’re a permanent Australian resident aged 18 or over.
- Get quotes from approved vendors. Only installers accredited by Plenti can apply for the rebate and loan on your behalf. Talk Energy is an approved vendor.
- Choose your system. Select a battery product from the approved list that meets WA network requirements and has a minimum 5kWh usable capacity.
- Your installer submits the application. Talk Energy lodges your rebate and loan application via Plenti. If you’re taking the no-interest loan, a credit check is conducted at this stage.
- Installation is completed. Your system is installed and connected to a VPP. The rebate is applied as an upfront discount, reducing your invoice immediately.
- Loan repayments begin. If you took the no-interest loan, repayments start after installation. There are no hidden fees and no interest charges, ever.
Important timing note: Once your loan application is approved, installation must be completed within six months. Don’t let an approved application lapse.
Why Your Choice of Installer Matters as Much as the Financing
Government financing removes the upfront cost barrier. But it doesn’t protect you from a poor installation, a slow response when something goes wrong, or an installer who subcontracts the work to whoever is available that week.
This is where choosing the right installer becomes critical, and it’s a decision that affects your system’s performance for the next 20 to 25 years.
What to Look for in a Solar Installer
When comparing installers for a scheme-funded installation, look beyond the price:
- In-house electricians: Some installers subcontract electrical work. This creates accountability gaps when issues arise. Installers who use their own licensed electricians for every job maintain consistent quality control.
- Workmanship warranty length: The industry standard is 5 to 10 years. A 20-year workmanship warranty is significantly above average and signals genuine confidence in the quality of the installation.
- Response guarantee: Solar systems can develop faults. How quickly will your installer respond? An explicit fix-or-replace guarantee with a defined timeframe is far more valuable than vague promises of “prompt service.”
- Accreditations: Look for CEC (Clean Energy Council) accreditation, along with any additional industry registrations.
- Financing speed: If you need installer financing to bridge any gap not covered by the WA scheme loan, the approval timeline matters. Slow financing can delay your installation by weeks.
Talk Energy’s Offering

| Fix or replace guarantee | 48-hour response |

The 20-year workmanship warranty and 48-hour fix guarantee represent a specific, legally binding commitment to the quality of the installation and the speed of response if anything goes wrong. For a system you’re financing over 3 to 10 years, that level of aftercare protection is exactly what you should be demanding from your installer.

Frequently Asked Questions
Can I get the WA scheme loan if I already have solar panels?
Yes, provided you’re adding a battery. The no-interest loan covers battery storage and any new or upgraded equipment (such as a hybrid inverter) installed alongside it. Existing solar panels that remain in place don’t need to be replaced; you simply need to be adding a new battery system that meets the minimum 5kWh usable capacity requirement.
What if I don’t qualify for the WA scheme loan?
If your household income exceeds $210,000 or you don’t pass the credit check, the WA scheme loan won’t be available to you. However, you can still access the upfront rebates (which don’t require a credit check) and Talk Energy’s own financing options. The rebates alone reduce a typical solar and battery package by $5,000 to $7,500 before any financing is applied.
Does the WA scheme cover solar panels without a battery?
No. The no-interest loan requires a battery to be installed as part of the system. Solar panels can be included in the loan, but only when bundled with a battery. If you want solar-only financing, Talk Energy’s fast financing is the pathway.
How long does the application process take?
Your installer submits the application on your behalf through Plenti. The credit assessment for the loan component is typically straightforward, and approvals can move quickly when you work with an experienced approved vendor. Once approved, you have six months to complete the installation.
Is the WA scheme running out?
The scheme has 100,000 rebate allocations statewide and is expected to remain open until approximately 2027. That sounds like a long time, but allocations are being claimed steadily. There’s no benefit to waiting, and a real risk that allocations run out before the scheme’s nominal end date.
