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 towards goals and guide research
Solar panels cost about $21,816 on average when purchased with cash or $26,004 when purchased with a loan for a 7.2 kW system. While that price tag seems steep, the electricity bill savings you get from solar panels
In 2024, solar photovoltaics (PV) were, on average, 41% cheaper than the lowest-cost fossil fuel alternatives, while onshore wind projects were 53% cheaper. Onshore wind remained the most affordable
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 cost
NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems.
Solar power costs in 2025 represent exceptional value for most homeowners, with system prices at historic lows and electricity rates continuing to rise. The combination of the 30% federal tax credit, improving
Is the price of solar panels falling? The price of solar panels has declined substantially over the last decade as the industry has matured and reached production at the largest global scale. Since 2010, the cost to install
Solar panel costs range from $16,600 to $20,500 for the average 6.5 kW system, but prices can vary from as little as $7,700 for smaller solar systems to upward of $34,700 for larger systems.
To reflect this difference, we report a weighted average cost for both wind and solar PV, based on the regional cost factors assumed for these technologies in AEO2022 and the actual regional distribution of the builds
Solar power costs in 2025 represent exceptional value for most homeowners, with system prices at historic lows and electricity rates
Solar photovoltaic module prices refer to the cost of the solar panel itself, and do not include installation or other system components. Prices are compiled from three sources: Nemet (2009) for 1975
