A 4 kW solar panel system costs $11,200 in 2025 before incentives. A 4 kW solar panel system produces about 5,808 kWh of electricity annually, but the exact amount depends on where you live and how much sun you get. DIYing a 4 kW solar panel system usually isn''t your best bet: You''re much better off hiring a professional solar company.
Larger systems, which produce more electricity, will naturally cost more. However, the cost per watt often decreases with larger systems due to economies of scale. For example, while a small 4 kW system might cost around $3 per watt, a larger 10 kW system might only cost $2.50 per watt. Not all solar panels are created equal.
