As of 2026, the average cost of residential solar panels in the U.S. is between $15,000 and $25,000 before incentives. This typically translates to about $2.50 to $3.50 per watt of installed capacity (more on price per watt below). The total price depends on your system size, location, roof type, and installer.
Another measure of the relative cost of solar energy is its price per kilowatt-hour (kWh). Whereas the price per watt considers the solar system's size, the price per kWh shows the price of the solar system per unit of energy it produces over a given period of time. Net cost of the system / lifetime output = cost per kilowatt hour

The price per watt for larger and relatively straightforward projects are often within the $2.50 to $3 range. Claiming incentives like tax credits and rebates can bring the PPW even lower. However, the following factors may push your solar price per watt into the $3 to $4.50 range.
Solar panels cost about $21,816 on average when purchased with cash or $26,004 when purchased with a loan for a 7.2 kW system. While that price tag seems steep, the electricity bill savings you get from
