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 a residential solar system cost?
Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400. Regional pricing differences, the system size, local installation costs, inclusion of home battery backup, and local incentives are other factors which affect the final cost.
Why do solar panels cost so much?
The size of your solar power system, measured in kilowatts (kW), is the most important factor affecting solar panel prices. Naturally, larger systems cost more than smaller ones, but they usually offer a lower cost per watt. Solar panels typically account for 12 - 18% of the total installation cost.
How much does solar installation cost?
Installation labor accounts for only 5.5-7% of total cost ($1,375-$2,500 for average systems), while soft costs represent 40-50% of total investment: Solar costs vary significantly by location due to labor rates, permitting requirements, market competition, and local incentives.
