Understanding NZ’s Solar Incentives and Rebates in 2025

Solar energy is steadily growing across New Zealand, and 2025 brings a renewed focus on making it more accessible and rewarding. While we don’t currently have nationwide subsidies for home solar systems, there are still several practical incentives and support options available for Kiwis keen to harness the sun’s power.

Competitive Buy-Back Rates from Power Retailers

The biggest incentive in 2025 comes from electricity retailers offering competitive rates for excess solar energy you send back to the grid. These buy-back rates have become a key part of the financial case for going solar.

Octopus Energy leads the way with peak-time rates of up to 40 cents per kilowatt-hour (kWh) during winter. Ecotricity offers up to 21 cents during peak hours, and Meridian Energy provides 17 cents per kWh plus a $300 account credit for customers on a fixed-term plan.

Other notable buy-back rates include:

Genesis: 12 cents per kWh

Powershop: 13 cents per kWh

Contact Energy: 8 cents per kWh

Nova Energy: 10 cents per kWh

Electric Kiwi: 8 to 12.5 cents per kWh depending on the plan

Choosing a retailer with strong buy-back rates can significantly improve your return on investment.

Green Loans to Help with Upfront Costs

While there’s no direct cash rebate from the government, several major banks are stepping in with low-interest and interest-free loans to make solar installations more affordable.

Westpac: Up to $50,000 interest-free for five years

ANZ: $3,000 to $80,000 at 1% interest for three years

BNZ: Up to $80,000 at 1% interest over three years

Kiwibank: Up to $2,000 contributed over four years for qualifying systems

These loans are designed to ease the financial load of going solar, especially when combined with modern systems that offer shorter payback periods and ongoing savings.

Support for Community-Based Solar Projects

The government is also investing in solar at the community level. Through the Community Renewable Energy Fund, $28 million is being directed into projects that bring renewable energy solutions to local areas. This includes community-owned solar farms and installations on commercial buildings where the benefits can be shared more widely.

No National Subsidies—But Still Worth It

While previous proposals for government-funded solar rebates haven’t come to fruition, the landscape is still supportive in other ways. The combination of generous buy-back schemes, attractive financing, and community programs keeps solar energy a strong option for homeowners in 2025.

Making the Switch

If you're considering solar this year, start by comparing power retailers’ buy-back rates, explore green loan options from your bank, and look into whether community projects in your area could support your goals. Even without a government rebate, going solar in New Zealand remains a forward-thinking, financially viable decision.
