Solar incentives come in layers, and stacking them is how homeowners cut their cost by half or more. Everyone starts with the 30% federal tax credit (deadline guide), then your state adds rebates, tax exemptions, and performance payments on top. Here is how the states stack up in 2026.
The Four Types of Solar Incentives
- Tax credits (federal 30%, plus some state credits).
- Rebates (up-front cash back).
- Tax exemptions (sales and property tax waived).
- Performance payments (SRECs / net metering) (you earn for what you produce).

How to Stack Your Incentives
- Start with the 30% federal credit.
- Apply any state rebate or credit.
