The ceiling price of solar panels

According to the National Renewable Energy Laboratory's Spring 2025 Solar Industry Update, residential solar costs average around $2.56 per watt before incentives, with most systems ranging from $2.56 to $3.03 per watt. Factors affecting cost per watt include:. 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 $19,873 after considering the full federal solar tax credit.. The industry standard measurement for comparing solar costs is price per watt ($/W). [PDF Version]
