But what does going solar really cost? The average solar installation in the United States (after the Federal Tax Credit) costs between $17,900 and $23,600, with the national average sitting at $20,948. That''s a significant drop from a decade ago, when residential solar systems could set you back over $50,000.
As of publishing, the average cost per watt is $2.84. Most solar companies set the price according to the solar system''s wattage. A solar installation''s “cost per watt” is a little like the “price per square foot” when you buy a house. It helps compare the value of solar energy systems in different sizes.
Solar panels generate “free” electricity, but installing a system still costs money. A typical American household needs a 10-kilowatt (kW) system to adequately power their home, which costs $28,241 in 2025. That price effectively drops to $19,873 after considering the full federal solar tax credit.
On average, homeowners with a complete solar system save $41,000 to $62,000 on total avoided energy costs over 25 years. It all depends on what your local utility charges for electricity, according to Robert Flores, a solar expert at The University of California, Irvine’s Clean Energy Institute.
