A 30-minute call with Stephen, the founder. He reads the Cary GSI Grant Program rules with you, tells you what to photograph and file first, and answers anything this page does not cover.
Confirm your project ZIP first. If this program does not serve your address, do not buy; check your city or utility on the rebates page instead.
One-time $29.99. Guidance, not filing: you submit to the program yourself. Not legal or financial advice. Rebate amounts and approval are decided by the program.
Every program listed cites its official source, and each program page shows the date we last verified it against that source. Program details change throughout the year, so always confirm requirements, amounts, and eligibility directly with the program before starting work.
