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.
That being said, the cost of solar panels isn't a one-size-fits-all figure. Several factors play into the final price you'll pay for solar energy, and understanding these variables is crucial. The average cost for solar panels in 2024 is around $2.50 to $3.50 per watt. This price includes both the cost of the panels and installation.
They store the energy accumulated from the solar panels. The price varies based on the installer, application and location. Batteries typically cost $12,000 to $22,000, according to the Department of Energy, although smaller capacity systems are available for less. In some cases, solar batteries may be more expensive than solar panels.
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.
