🇺🇸 Solar Rebates & Incentives in United States

Administered by the Energy Efficiency and Conservation Authority (EECA), this grant covers up to 30% of solar installation costs, capped at NZD $5,000 for residential properties and NZD $25,000 for commercial projects. The program aims to reduce upfront costs and make solar power more accessible to New Zealanders.

A government-backed fund providing solar PV and battery systems to community resilience sites across New Zealand. By end of 2025, an estimated 217 community sites will have been selected, with an average cost of $88,000 per site. The fund supports community facilities such as marae, community halls, and emergency shelters.

EECA's fund to support solar and battery uptake on New Zealand farms. The program covers up to 40% of inverter and battery system costs, capped at $450/kWh of nominal battery capacity, up to a maximum of $100,000. It aims to demonstrate the viability of solar energy for agricultural operations.

From May 2025, the Investment Boost initiative through Inland Revenue allows businesses to immediately deduct 20% of the cost of new eligible assets including commercial solar power systems. This accelerated depreciation reduces the effective cost of solar installations for businesses across New Zealand.

While primarily focused on insulation and heating, the Warmer Kiwi Homes programme is expanding to cover rooftop solar installations through interest-free loans for up to 12 years. The programme helps make New Zealand homes warmer, drier, and more energy-efficient, and has been extended to June 2027.

India's flagship rooftop solar scheme announced on 15 February 2024 with an outlay of Rs 75,021 crore, aiming to install rooftop solar on one crore (10 million) households by FY 2026-27. The central government provides direct subsidies of Rs 30,000 per kW for the first 2 kW and Rs 18,000 per kW for the third kW, up to a maximum of Rs 78,000 for a 3 kW system. Households receive up to 300 free units of electricity per month and can earn additional income by selling surplus power to DISCOMs. As of December 2025, over 19.4 lakh rooftop solar systems have been installed across India, with subsidies totalling about Rs 9,280 crore.

The Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyaan (PM-KUSUM) scheme was launched in March 2019 to provide solar energy solutions for farmers, reduce diesel dependency, and increase farmer incomes. The scheme targets 34,800 MW of solar capacity by March 2026 with central financial support of Rs 34,422 crore. It has three components: Component-A for 10,000 MW ground-mounted solar plants, Component-B for 14 lakh standalone solar agriculture pumps, and Component-C for solarisation of 35 lakh grid-connected agriculture pumps. In FY2025, Component-B saw a 4.2-fold increase in pump installations (4.4 lakh pumps), while Component-C solarised 2.6 lakh pumps (25x over FY2024).

India's state electricity regulatory commissions (SERCs) mandate net metering for rooftop solar installations across all states and union territories. Under net metering, excess solar electricity generated is fed back into the grid and credited against the consumer's electricity bill. Most states allow net metering for systems up to 500 kW-1 MW capacity. In 2024-2025, states are increasingly adopting Virtual Net Metering (VNM) and Group Net Metering to enable apartments, housing societies, and multi-connection consumers to share solar credits. Maharashtra, Telangana, and Andhra Pradesh have published updated VNM/GNM regulations. Net billing (crediting exports at wholesale rate rather than retail rate) is also emerging as a complementary model in some states.

The Fundo Clima (National Fund on Climate Change), managed by BNDES under coordination of the Ministry of the Environment, is Brazil's main public climate finance instrument for renewable energy investments. After depletion during 2019-2022, the fund was reactivated in 2023 with R$ 630 million and expanded to R$ 10.4 billion in 2024. BNDES announced a R$ 20 billion green credit programme for solar and wind generation projects, with a focus on small and medium enterprises. The fund provides subsidised financing (below-market interest rates) for solar energy generation and distribution projects, technological development in the solar sector, and supporting the clean energy transition. R$ 15 billion in approvals projected for clean energy in 2025.

Brazil's flagship social housing programme, Minha Casa Minha Vida (MCMV), was relaunched in February 2023 by President Lula with updated sustainability guidelines that promote the integration of solar energy systems in new housing developments. The programme now includes measures for the installation of solar panels, rainwater reuse, and ecologically correct building materials in affordable housing projects for low-income families. Solar integration reduces ongoing electricity costs for beneficiaries and contributes to Brazil's renewable energy targets. The programme targets families earning up to R$ 8,000 per month, with specific incentives for construction and renovation in both urban and rural areas.

The business-claimed 48E Investment Tax Credit remains available for third-party-owned residential solar installations such as leases and power purchase agreements (PPAs). Solar companies claim the 30% credit and pass savings to homeowners through lower lease or PPA rates. This credit continues through the end of 2027.
