How Much Do Solar Panels Cost in 2025?
Solar installation costs vary significantly by location due to differences in labor rates, local incentives, permitting fees and electricity prices. The national average is around $20,000.
The price of solar panels changes depending on where you live, but the average for installation is just under $29,000 or $2.75 per watt. On the high end, we talked to a solar customer in Hawaii who spent $100,000 going solar. Dion in Nevada said their 10-kW system cost about $20,000, which is about the national average price for a 7-kW system.
The cost of an inverter depends on its size and efficiency, but these devices typically cost between $1,000 and $3,000. Mounting system: This is what holds rooftop solar panels in place. Costs vary depending on the type of solar installation, but it generally costs between 7 and 20 cents per watt.
A 20ft shipping container can typically accommodate 6 to 12 solar panels, depending on panel size and mounting configuration. With six to twelve 300W panels, you can expect around 1.8 kWp to 3.6 kWp of power. For more compact setups or higher-efficiency panels (400W or more), up to 12 panels could generate as much as 4.8 kWp.
