The price of a 18kw solar system is from $4000 to $9200, It depends on which option you choose, if it’s a on grid system without batteries the cost is much lower. If you need batteries as a back-up then off-grid and hybrid are great options with 20kWh, 30kWh, 40kWh or even larger capacity batteries. [pdf]

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]
