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.
Since 2010, the cost to install solar panels on a home has fallen by roughly 50%. Costs rose slightly from 2020-2023 largely due to supply chain tangles from the pandemic, and
The technology we choose for the solar panels will drastically change the cost of the solar panels per square meter. As the monocrystalline panel is compact and has higher
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.
In 2025, the average cost for a professionally installed rooftop solar system in America is typically between $15,000 and $30,000 before any tax credits or incentives are applied.
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
In 2025, the average cost for a professionally installed rooftop solar system in America is typically between $15,000 and $30,000 before any tax credits or incentives are
The average cost of a home solar panel system is about $30,000. Tax credits and incentives may reduce net cost of solar panels to about $21,000.
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

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.
One of the biggest cost factors for your solar panel installation is the size of the system you have installed. System size is measured in kilowatts (kW) and is determined by household energy consumption. The average cost per watt is $3.04, but larger systems often have a lower cost per watt.
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.
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.
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.
Let’s use a polycrystalline panel as an example. An average polycrystalline panel offers 160 watts per m2 for $140. Thus, the cost per watt for that panel is $0.87. A high-efficiency PERC panel may offer 200 watts for an area of $180, thus accounting for about $0.90 per watt.
