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

Verify that your solar installer is properly licensed. This helps ensure that the work is done properly using the most up-to-date installation methods. In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including home solar installers.

Read Customer Reviews

Look at review platforms such as TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to find out what previous customers have to say about local solar installers. Reviews can give you an idea of a company’s reliability and customer service. Be wary of companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

Get free, detailed quotes from 3–5 solar companies. A quote should describe 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

Top-notch solar installations should come with strong workmanship and performance guarantees. A workmanship warranty covers installation issues, such as cracks in the panels, poor wiring, or poor alignment. A performance guarantee ensures a minimum energy output. Comprehensive guarantees show that a solar company believes in its work.

Evaluate Financing and Incentives

Going solar can help lower your electric bills over time. When evaluating the total price and value of solar panels, make 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 offer substantial savings for solar customers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with leases or loans. Check key financing details like annual percentage rate (APR), payment schedule, fees, and ownership implications when financing solar panels.
  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to switch to solar power. Check the eligibility rules and rebate values with your local electric company to find out what you could save.
