Solar Photovoltaic System Cost Benchmarks
The U.S. Department of Energy''s solar office and its national laboratory partners analyze cost data for U.S. solar photovoltaic systems to develop cost benchmarks to measure progress
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.
Average price of solar modules, expressed in US dollars per watt, adjusted for inflation. Data source: IRENA (2025); Nemet (2009); Farmer and Lafond (2016) – Learn more about this data Note: Costs are expressed in constant 2024 US$ per watt.
Federal tax credits can reduce upfront costs by up to 30%. Commercial systems often start at 25 kW and can exceed 250 kW. A 50 kW system costs $120,000-$200,000 before incentives, with larger projects reaching $500,000-$1,000,000.
Local governments often require permits for solar installations, which may cost $100-$500 based on regional regulations. Inspections ensure compliance with building and electrical codes, typically adding another $100-$300 to the expenses. These fees vary by jurisdiction but contribute to a safe and code-compliant installation process.
