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
Pro tip: It can be helpful to know your solar price per watt before and after claiming the 30% tax credit. Ultimately, many factors figure into the price per watt of a solar system, but the average cost is typically as low as $2.75 per watt.
As of 2025, 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.
Solar panel costs are usually measured in the cost per watt of solar installed. However, solar system sizes are measured in kilowatts (kW). To calculate the total price of installing a home solar system, you’ll need the system size to be in watts. To convert kilowatts to watts, all you need to do is multiply the system size in kW by 1,000.
