Compare Top Solar Panels: Performance, Costs
Use our tool to compare a range of solar panel variants, sizes and available brands and see which solar modules excel depending on your home
As of 2025, the average cost of residential solar panels in the U.S. is between $15,000 and $25,000 before incentives. This typically translates to about $2.50 to $3.50 per watt of installed capacity (more on price per watt below). The total price depends on your system size, location, roof type, and installer.
Monocrystalline panels are highly energy efficient and, as such, cost the most at $1 to $1.50 per watt. Outfitting a 6 kW solar system costs $6,000 to $9,000. Polycrystalline panels cost $0.90 to $1 per watt. You can tell them apart from other panels because they're blue.
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. A single solar cell costs about $0.30 and most panels use 60 or 72 cells. The more cells in a panel, the higher the cost.
Ultimately, many factors figure into the price per watt of a solar system, but the average cost is typically as low as $2.75 per watt. This price will vary if a project requires special adders like ground mounting, a main panel upgrade, an EV charger, etc.
