Many states provide rebates for home solar power systems in addition to the federal solar tax credit. These incentives not only vary by state but can also differ between utility companies within the same state, and rebate amounts are subject to frequent changes. For the most accurate and current details on state incentives, refer to the Database of State Incentives for Renewable Energy (DSIRE) , which is a comprehensive online database that provides information on policies, incentives, and programs for renewable energy, including solar power, as well as energy efficiency across the United States. It is an authoritative source for finding federal, state, local, and utility incentives related to renewable energy and energy efficiency. The link to the datatbase is mentioned as below
