Solar Panel Cost by State
Mid installed cost for a typical 7 kW residential solar system across all 50 states + DC, plus PVWatts specific yield and current retail electricity rate. The federal 25D Residential Clean Energy Credit (30%) expired for property placed in service after 2025-12-31, so the figures below are gross installed cost — state and utility programs may reduce net cost further.
