What's Happening?
California continues to offer several key incentives for solar and battery storage installations, even after the federal residential solar tax credit (Section 25D) ended for new installations after December 31, 2025. The Self-Generation Incentive Program
(SGIP) remains active, supporting qualifying behind-the-meter storage, with higher equity and resiliency levels available for specific income, medical-vulnerability, and wildfire-risk requirements. The California Public Utilities Commission's (CPUC) Residential Solar and Storage Equity program also supports eligible low-income households installing paired solar and storage systems. Additionally, the DAC-SASH program is accepting applications for income-eligible homeowners in disadvantaged communities. While the federal tax credit is no longer available for new homeowner-owned systems, third-party system owners may still be eligible for separate business-side clean-energy credits, which can influence contractual pricing for consumers.
Why It's Important?
These ongoing California incentives are crucial for sustaining the growth of solar and battery storage adoption in the state, particularly for low-income households and those in disadvantaged communities. The SGIP and Residential Solar and Storage Equity programs address critical needs by making clean energy more accessible and affordable for vulnerable populations, enhancing energy resilience, especially in areas prone to wildfires. The continued support for battery storage is vital for grid stability and optimizing solar energy use, allowing homeowners to store excess power and reduce reliance on the grid during peak demand. The expiration of the federal tax credit shifts a greater burden onto state and local incentives to drive solar adoption, making California's continued commitment to these programs even more significant for its clean energy goals and for consumers seeking to reduce electricity costs.
What's Next?
Homeowners in California interested in solar and battery storage should confirm their eligibility for programs like SGIP, Residential Solar and Storage Equity, and DAC-SASH, as funding steps and waitlists can change. It is important to check current funding, income rules, developer approval, and participation requirements before assuming an award. When considering prepaid power purchase agreements (PPAs) or leases, homeowners should understand that the third-party owner typically claims business-side tax benefits, not the homeowner. The active-solar property tax exclusion, which prevents qualifying solar systems from increasing property assessments, is currently set to sunset on January 1, 2027, and its future treatment should be confirmed. Homeowners should also be aware of California's Net Billing Tariff for new rooftop solar, which provides time-dependent credits for excess energy sent to the grid, emphasizing the importance of battery dispatch and system sizing.
Beyond the Headlines
California's sustained investment in solar and battery storage incentives, particularly those targeting low-income and disadvantaged communities, reflects a progressive approach to energy equity and climate resilience. By focusing on these specific demographics, the state aims to ensure that the benefits of clean energy are broadly distributed, addressing historical disparities in access to renewable technologies. The emphasis on battery storage, alongside solar, underscores a strategic vision for a more resilient and flexible energy grid, capable of managing intermittent renewable generation and providing backup power during outages. The shift in the incentive landscape, with the federal residential tax credit ending, highlights the increasing importance of state-level policy leadership in driving the clean energy transition. This situation also brings to the forefront the complexities of ownership models (homeowner vs. third-party) and how they impact who benefits from various tax credits and incentives, necessitating careful consideration by consumers.
