How much does a solar system cost per watt?
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. This price will vary if a project requires special adders like ground mounting, a main panel upgrade, an EV charger, etc.
How much do solar panels cost?
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.
What is the relative cost of solar energy?
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
How much does a solar energy storage battery cost?
Solar batteries let you keep your lights on even when your local power grid is down. However, battery storage typically costs between $7,000 and $18,000. If you live in an area with frequent power outages, a solar energy storage battery is worth considering. Other equipment also factors into the overall price:
