About solar energy grants

Solar and clean energy grants fund installations, research, workforce development, and community energy programs. The Department of Energy, EPA, USDA, and state energy offices are major funders, especially after the Inflation Reduction Act expanded clean energy incentives. Both tax credits and direct grants are available for solar projects.

Frequently Asked Questions

What federal grants are available for solar projects?

The DOE's Solar Energy Technologies Office funds research and deployment. The USDA REAP program provides grants for rural solar installations. The EPA's Greenhouse Gas Reduction Fund supports community solar. The Inflation Reduction Act created new direct-pay options for tax-exempt organizations, effectively functioning as grants for solar installations.

Can nonprofits get solar grants?

Yes. Nonprofits can now benefit from the IRA's direct-pay provisions for clean energy tax credits. The EPA's Solar for All program specifically serves low-income and disadvantaged communities. State programs like California's SASH and New York's NY-Sun include nonprofit pathways. Many utility companies offer solar incentive programs for nonprofits.

Are there grants for community solar projects?

Yes. The EPA's $7 billion Solar for All program is the largest community solar grant in history. USDA's Rural Energy for America Program supports rural community solar. State clean energy funds in Colorado, Minnesota, Illinois, and others specifically fund community solar development.
