The cost per square foot for residential solar panels is estimated to be between $4 and $10 (≈40 minutes working at a $15/hour wage), though most estimates are based on
Today’s premium monocrystalline solar panels typically cost between 30 and 50 cents per Watt, putting the price of a single 400-watt solar panel between $120 to $200, depending on how you buy it. Less efficient polycrystalline panels are typically cheaper at $0.25 per Watt. The cost of a solar panel also depends on how you buy it.
According to studies by the U.S. Department of Energy, the all-in cost of a home solar panel system is between $2.74 to $3.30 per watt. 1,2,12 This figure includes the solar panels, the installation, and other expenses. Using these numbers, an average-sized 8-kilowatt residential solar system would cost between $21,900 – $26,400.
Commercial solar installations are a great way for companies to lower energy costs. Generally, installing solar panels on businesses costs a bit less per watt because the systems are larger, but the total costs will be higher. In 2025, the average cost for commercial solar panels is just about $2.00 per watt.
