Solar installers design and mount photovoltaic systems, handling permits, utility interconnection, and often batteries. A residential system runs $15,000 to $30,000 before incentives, with the federal tax credit and local rebates cutting that substantially; savings depend on your rates, roof, and sun exposure.

How to Hire Solar Installers in 2026
Get multiple quotes and compare system size in kilowatts, panel and inverter brands, and the production estimate in kilowatt-hours per year, not just price. Confirm the installer is licensed, since solar usually requires an electrical or specialty license, and handles permitting and interconnection. Ask how they assessed your roof's age and condition, because re-roofing under panels later is costly.
Scrutinize the warranty, since panels, inverter, and workmanship are separate, and whether you are buying, leasing, or signing a power-purchase agreement, because ownership captures the tax credit and the most savings. Be wary of high-pressure door-to-door sales and inflated savings claims. A solid proposal shows the production estimate, all-in cost after incentives, and a realistic payback period.
Solar Installers FAQs
How much does a solar system cost?
A residential solar system runs roughly $15,000 to $30,000 before incentives, or about $2.50 to $3.50 per watt. The federal residential clean-energy tax credit and state or utility rebates can reduce the net cost by 30% or more. Adding battery storage increases the total.
Do solar installers need a license?
Yes, in most states solar installation requires an electrical or specialty contractor license because it ties into your electrical system and the grid. Installers also handle permitting and utility interconnection. Verify the license, insurance, and that permits and interconnection are included in the quote.
Is solar worth it?
It depends on your electricity rates, roof orientation and shading, local incentives, and whether you buy or lease. Owned systems in sunny, high-rate areas often pay back in 7 to 12 years and save money after that. Get a production estimate and a payback analysis specific to your home, not a generic pitch.
Should I re-roof before installing solar?
If your roof is more than 10 to 15 years old, re-roof first, because removing and reinstalling panels later to replace the roof underneath is expensive. A good installer assesses roof age and condition up front and will tell you if it should be replaced before mounting a 25-year system.
