How To Choose a Solar Company

Putting solar panels on your roof could reduce your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

It's important to hire a licensed solar installer. This help guarantee that the work is done correctly using current best installation practices. In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including solar contractors.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's dependability and customer service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from 3–5 solar companies. The quotes should list all costs and identify the solar parts included. Comparing several quotes can help you find the best value for your budget.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance guarantees. A workmanship guarantee addresses any installation defects (such as cracks in the panels, poor wiring, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

Solar energy can help reduce your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.

  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to total system costs is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar buyers.
  • Look into utility rebates: More discounts might be available from local power companies looking to motivate homeowners to go solar. Contact your local utility provider to learn rebate values and qualification criteria, so you can calculate your possible savings.
  • Compare system purchase options: Solar panels may be paid for outright or financed through leases or loans. Confirm important financing details such as annual percentage rate (APR), payment schedule, fees, and ownership implications when financing your solar system.
