NSW homeowners can now access zero-interest loans of up to $15,000 for solar panel installations, home batteries, and a range of other energy-efficient upgrades, with applications opening today, June 17, 2026. The state government has allocated a significant $480 million to the scheme, aiming to assist approximately 32,000 households in reducing their energy bills over the next decade.
Premier Chris Minns stated that the initiative directly addresses the substantial upfront costs that have historically deterred many households from investing in energy-saving home improvements. The loans are repayable over 10 years at zero per cent interest, making advanced energy solutions more accessible to eligible residents.

Who Qualifies for the NSW Zero-Interest Loan?
To be eligible for the zero-interest loan, NSW homeowners must have a combined household income of $210,000 or less. The program is designed to complement existing federal incentives, not replace them, allowing households to stack rebates for maximum savings.
In addition to the loans, separate cash subsidies of up to $4,000 will become available later this year for concession card holders and households earning under $80,000 annually. The government recommends that eligible households apply for these cash subsidies first, then utilise the zero-interest loan to cover any remaining costs. Renters in NSW can also access both the loans and subsidies, provided they secure landlord approval for the upgrades.
What Energy Upgrades Are Covered?
The comprehensive list of eligible upgrades extends beyond solar and batteries to encompass a wide array of home energy improvements. This flexibility allows homeowners to implement a package of upgrades, rather than being limited to single installations.
Eligible upgrades include:
- Solar panels
- Home battery storage systems
- Switchboard upgrades
- Ceiling insulation
- Draught-proofing
- Double glazing
- Solar hot water heaters
- Reverse-cycle air conditioners
- Induction cooktops
- Electric vehicle (EV) chargers
- DC ceiling fans
This broad scope means households can address multiple energy efficiency needs, from generating their own power to improving thermal performance and electrifying their homes. For those considering a full transition from gas to electric appliances, this loan could significantly ease the financial burden. Is a Gas to Electric Home Conversion Worth It in Australia 2026?

Stacking Savings: Federal Rebates and the NSW Loan
The NSW zero-interest loan is designed to work in conjunction with existing federal incentives, offering a powerful combination for reducing upfront costs. For instance, a typical household installing a 6.6 kW solar system paired with a 10 kWh battery might face an initial cost of approximately $18,000 to $22,000 before any rebates.
Federal rebates significantly reduce this figure:
- Small-scale Technology Certificates (STCs): For solar panels, the federal STC rebate typically provides $1,500 to $2,500 as a point-of-sale discount, automatically applied by the installer.
- Cheaper Home Batteries Program: This federal program offers a discount of approximately $244 per kWh for the first 14 kWh of battery capacity. A 10 kWh battery would therefore receive around $2,440 in federal rebate.
After applying these federal incentives, the remaining out-of-pocket cost for the 6.6 kW solar and 10 kWh battery system would typically fall between $14,000 and $18,000. The new NSW zero-interest loan can then cover this remaining amount, making the upfront cost manageable for eligible households.
Illustrative System Costs After Rebates
| System Component | Estimated Pre-Rebate Cost (AUD) | Federal STC/Battery Rebate (AUD) | Post-Federal Rebate Cost (AUD) |
|---|---|---|---|
| 6.6 kW Solar System | $5,000 - $7,500 | $1,500 - $2,500 | $3,500 - $5,000 |
| 10 kWh Home Battery | $8,000 - $12,000 | Approx. $2,440 | $5,560 - $9,560 |
| Combined (6.6kW Solar + 10kWh Battery) | $13,000 - $19,500 | $3,940 - $4,940 | $9,060 - $14,560 |
Note: These are indicative figures; actual costs and rebate values may vary based on specific products, installer, and STC zone. The NSW loan can cover up to $15,000 of the ‘Post-Federal Rebate Cost’.
Impact on NSW Energy Transition
The introduction of these loans is expected to significantly accelerate the adoption of rooftop solar and battery storage across NSW. By addressing the primary barrier of upfront cost, the state government aims to empower more households to generate and store their own clean energy, thereby reducing their reliance on the grid and mitigating the impact of rising electricity prices.
Increased uptake of home batteries, supported by programs like this, plays a crucial role in stabilising the grid by enabling households to store excess solar generation for use during peak demand periods. This distributed energy resource contributes to a more resilient and sustainable energy system for all.

This initiative also aligns with broader national efforts to transition to renewable energy and improve household energy efficiency.
