How much does a residential solar panel system cost in 2026

Costs vary by installer, location, and system complexity, so get multiple quotes rather than assuming a fixed price. The per watt cost covers panels, inverters, mounting, wiring, and labor combined.
Breaking down the expense
Panel hardware typically accounts for 40 to 50 percent of costs, while labor, permitting, and electrical components make up the rest. Roof condition, complexity, and local wages all influence final pricing. Ground mounted systems often cost more than roof systems due to extra structural work. Get at least three quotes in writing before deciding.
Tax credits and incentives
Federal tax credits can reduce your cost significantly, plus many states offer additional rebates or performance incentives. These shrink your actual out of pocket cost substantially. Check your state and local utility websites for current programs. Some incentives change annually, so confirm what applies to your project timeline.
