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.
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.
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
Your state's averages matter more than national numbers, and factors like shading, roof complexity, and local incentive programs all play a role in your final price. The average cost of a 12 kW solar panel installation on EnergySage is $30,505 before available incentives.
