⚠️ All solar cost and savings estimates are informational only and not a substitute for a professional quote.
Our calculators use national average solar pricing, typical sun hour data by region, and simplified formulas. Actual costs and savings depend on your specific roof, local installer pricing, utility rate structure, and net metering policy.
Federal and state solar incentives change based on legislation. The 30% federal residential solar tax credit expired December 31, 2025. We aim to keep this site updated, but always verify current incentives with your tax professional or state energy office before making purchasing decisions.
Actual solar production depends on roof orientation, shading, local weather patterns, and equipment specifics that only a professional site assessment can evaluate. Always get an in-person or satellite-based assessment from a licensed solar installer.
We recommend getting at least 3 quotes from licensed solar installers before signing a contract. Compare system size, equipment brands, warranty terms, and financing options.
