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
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.
Based on our 2025 survey of 1,000 solar customers, the national average price for a single solar panel professionally installed is $1,200. This means most full-size systems of between 20 and 30 panels
Solar panel costs can be affected by many factors, including system size, type of panel and home electricity needs. We break down these and other factors in our solar panel cost guide.
Residential solar panels are usually sized between 3 kW and 8 kW and can cost anywhere from $7,500 to $28,000 in total installation costs. See average solar panel system costs by
We analyzed thousands of systems sold on solar in recent years to find the average cost of solar panels for homes based on their square footage of living space and number of bedrooms.
This guide explains the costs involved in going solar, factors that affect pricing, and how to decide if solar panels are the right choice for you.
