The industry standard measurement for comparing solar costs is price per watt ($/W). According to the National Renewable Energy Laboratory's Spring 2025 Solar Industry Update, residential solar costs average around $2.56 per watt before incentives, with most systems ranging from $2.56 to $3.03 per watt. Factors affecting cost per watt include:
Note: Costs are expressed in constant 2024 US$ per watt. Global estimates are used before 2010; European market benchmarks thereafter due to limited data availability. Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components.
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.
These costs are for a typical 7 kW residential system ($19,873 average). Monocrystalline or polycrystalline panels are the most common types of solar panels. Most residential installations use monocrystalline photovoltaics (PV) panels, which offer up to 24% efficiency and perform better in limited space and extreme temperatures.
