How Solar Panel Costs Are Calculated

Solar panel installation costs vary by location based on labor rates, permitting fees, local incentives, and electricity rates. Our estimates use NREL solar irradiance data for each city combined with state-level average installation costs from the Solar Energy Industries Association (SEIA).

All costs shown are for a standard 6kW residential system. The 30% federal Investment Tax Credit (ITC) applies to most residential installations through 2032. Many states and utilities offer additional incentives that can reduce costs further.
