How much does a 6 kW solar system cost?

You’ll pay $4,200 to $6,000 to set up a 6 kW system. Concentrated photovoltaic (CPV) panels are $0.80 to $1.10 per watt. While not as well-known as other types of panels, CPV panels are highly efficient and may grow in popularity. A 6 kW solar system would cost $4,800 to $6,600.

How much does solar power cost in 2025?

Take control of your energy costs with solar power. 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.
