How To Choose a Solar Company

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

Check Licensing

Confirm that your solar installer is properly licensed. This ensures that the work is done properly using current installation best practices. In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including home solar installers.

Read Customer Reviews

Check consumer review platforms like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with providers that have hardly any reviews or mostly negative ones.

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. The quotes should describe all costs and identify the solar parts included. Looking at several quotes can help you find the best value for your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to install solar panels. Check the qualification criteria and rebate values with your local utility provider to determine what you could save.
  • Compare system purchase options: Solar panels may be paid for upfront or financed through a lease or loan. Check important financing details such as annual percentage rate (APR), payment schedule, fees, 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 provide incentives. The credits can result in significant savings for solar buyers.
