The following table shows the prices per solar panel, per Wp and per kWh, the number of square meters that these panels occupy, and including installation, materials.
Finally, they add in costs associated with permitting, inspection, interconnection, and other overhead. NREL''s bottom-up cost modeling methodology, shown here for residential

Global cost per m² in 2025 varied immensely across regions because of labor, logistics, and policy support. In the United States, a typical solar panel cost per square meter in residential installations is between $280–$320 per m² because labor and permission expenses are higher.
Solar panel installation costs depend on your home's size, energy needs, roof structure, and location. You can estimate around $10 to $15 per square foot of living space for solar panel installation. Keep in mind, this estimate doesn’t account for tax credits or local incentives, which can significantly reduce your final cost.
In this guide, we’ll break down average solar costs per square foot in 2025, show how they compare by home size, explain why this metric has limits, and give you expert tips to reduce your price. Average U.S. solar cost per square foot in 2025: $6 – $12 after the 30% federal tax credit.
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.
Divide annual kWh by ~1,200 (typical kWh/year per kW of solar in much of California). In California, expect $2.75 – $3.50 per watt before incentives (solar panel cost in California). This gives your solar cost per square foot. Estimate your system size, price before and after incentives, and cost per square foot.
As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system's wattage. A solar installation's “cost per watt” is a little like the “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes.
