How To Choose a Solar Company

Going solar can be a great way to reduce electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when evaluating if a solar installer is trustworthy.

Check Licensing

It's imperative that your solar installer has the proper licensing. This help guarantee that the work is done properly using the most up-to-date installation methods. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including home solar installers.

Read Customer Reviews

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

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. The quotes should explain all costs and list the solar equipment included. Reviewing multiple quotes helps you find the best option that fits 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 poor wiring, cracks in the panels, 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 power can help reduce your electricity costs over time. When considering solar panel's cost and value, be sure to factor in these considerations.

  • Look into utility rebates: Local power companies may have extra rebates to motivate homeowners to install solar panels. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • Compare system purchase options: Homeowners may purchase solar panels outright or finance payments over time with loans or leases. Be sure to confirm key details like annual percentage rate (APR), payment schedule, fees, and what ownership means when financing solar panels.
  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states offer incentives, too. The credits can result in substantial savings for solar buyers.
