Increases the amount of residential solar tax credits

This bill increases residential solar tax credits by raising the credit rate to 26% of qualified solar equipment costs. It sets new annual credit limits: $3,750 for systems installed before 2026, $5,000 for 2026-2025, and $10,000 for systems installed on or after January 1, 2026. The credit applies to homeowners who install qualifying solar systems (including equipment for heating, cooling, hot water, or electricity) at their primary residence, covering equipment purchases, installation, and certain lease agreements. Low-income taxpayers and those in disadvantaged communities may receive refunds for excess credits starting in 2026, rather than carrying them forward. The policy directly affects residential property owners installing solar energy systems in the state.
