To estimate how much you'll pay for solar, multiply the size of your system (in watts) by the average cost per watt in your area—$2.53/W across the U.S., according to EnergySage data. Right now, a 12-kilowatt (kW) solar panel system (the average quoted size on EnergySage) costs about $29,649 before any available incentives.
The quoted price of a solar power system also includes soft costs that are not evident when looking at a completed installation: permitting, inspections, grid interconnection, taxes, transportation, land acquisition, design work, skilled labor, customer acquisition, overhead, profit margins, etc.
