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. [pdf]
