As of 2026, the average cost of residential solar panels in the U. is between $15,000 and $25,000 before incentives. This typically translates to about $2. 50 per watt of installed capacity (more on price per watt below). Department of Energy (DOE) Solar Energy Technologies Office (SETO) and its national laboratory partners analyze cost data for U. solar photovoltaic (PV) systems to develop cost benchmarks. The total price depends on your system size, location, roof type. . Caution: Photovoltaic system performance predictions calculated by PVWatts ® include many inherent assumptions and uncertainties and do not reflect variations between PV technologies nor site-specific characteristics except as represented by PVWatts ® inputs. Factors influencing the cost include system size, installation location, equipment quality, and government incentives.
