How To Choose a Solar Company

Installing solar panels can lower your electricity costs and help the environment by reducing your carbon footprint. When determining whether a solar provider is right for you, consider these key factors.

Check Licensing

Confirm that your solar installer is properly licensed. 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 solar contractors.

Read Customer Reviews

Check consumer review platforms like the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. These quotes should describe all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.

Ask About the Warranty

High-quality solar installations should include robust workmanship and performance guarantees. The workmanship warranty covers any installation issues like cracks in the panels, poor wiring, or poor alignment. The output guarantee ensures an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.

Evaluate Financing and Incentives

Solar is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • Compare system purchase options: Solar panels can be purchased outright or financed through a loan or lease. Review important financing details such as annual percentage rate (APR), fees, payment schedule, and ownership implications when financing your solar system.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can add up to significant savings for solar buyers.
  • Look into utility rebates: Some energy providers may provide additional rebates to incentivize homeowners to install solar panels. Check the eligibility criteria and rebate amounts offered by your local electric utility to determine the possible savings.
