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.
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.
If you just need a few panels for a small do-it-yourself project, expect to pay around $200 to $350 per panel (between $0.80 and $1.40 per watt). These prices don't include the cost of a solar storage battery, which can add anywhere from $7,000 to $18,000 to your total solar system costs.
The average 6-kW residential solar panel installation is $17,852 before incentives. Learn about cost factors, financing options, tax breaks and more.
