Estimate your HEAR rebate, 25C tax credit, and utility rebate in 30 seconds. Select your project type, income level, and utility to see total potential savings.
This calculator estimates three stacked incentive layers available in 2026: HEAR rebates (income-qualified, state-administered), the federal 25C tax credit (30% of cost, available to all), and utility rebates (varies by provider). The HEAR rebate is subtracted from your cost first, then the 25C applies to the remaining balance up to the program cap.
