How To Choose a Solar Company

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

Check Licensing

Hiring a licensed solar installer is critical. This helps ensure that the work is done properly using current installation best practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including residential solar contractors.

Read Customer Reviews

Check the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers are saying about local solar installers. Detailed reviews on these platforms can help you assess a provider's integrity and customer service. Be wary of providers with few or mainly poor reviews.

Compare Multiple Quotes

Contact 3–5 solar companies to receive free, detailed quotes. Quotes should clearly explain all costs and specify the exact solar components included. Comparing multiple quotes helps identify the best value based on your budget.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation problems such as poor wiring, cracks in the panels, or poor alignment. The performance guarantee promises a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Switching to solar power can help lower your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.

  • Compare system purchase options: Homeowners may purchase solar panels upfront or finance payments over time with a lease or loan. Be sure to check key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • Look into utility rebates: Local power companies may have extra rebates to motivate homeowners to adopt solar power. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • 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 have incentives. These credits offer substantial savings for solar customers.
