Why Is Solar Installation So Expensive?
Breaking down the real costs behind solar panel installation: equipment, labor, permits, and profit margins. Understanding where your money goes.
The Short Answer
Solar installation costs $2.50-$4.00 per watt in 2026. For a typical 6kW system, that's $15,000-$24,000 before incentives. The equipment is only about 35% of the cost. Labor, permits, overhead, and profit make up the rest.
