Average U.S. solar cost per square foot in 2025: $6 – $12 after the 30% federal tax credit. Cost per square foot varies by system size, energy use, location, and panel efficiency. The most accurate pricing metric is still cost per watt, but per-sq-ft estimates are helpful for ballpark figures.
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.
Solar energy per square meter is the quantity of sunlight energy (or irradiance) that reaches a one square meter surface region over a specific time period. It is generally measured in watts per square meter (W/m²), and there are variations across several factors like the geographical site, time of the year, and local weather situations.
