How much do solar panels cost?
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.
How much does solar cost per watt?
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.
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 7 kW solar system cost?
These costs are for a typical 7 kW residential system ($19,873 average). Monocrystalline or polycrystalline panels are the most common types of solar panels. Most residential installations use monocrystalline photovoltaics (PV) panels, which offer up to 24% efficiency and perform better in limited space and extreme temperatures.
