How To Choose a Solar Company

Putting solar panels on your roof could cut your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

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

Read Customer Reviews

Check review sites 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 very few reviews or mostly negative ones.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. The quotes should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the most cost-effective option for your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to the full system cost is available through 2032. Many states also have incentives. These credits offer substantial savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with leases or loans. Confirm key financing details like payment schedule, fees, annual percentage rate (APR), and ownership implications when choosing to finance solar panels.
  • Look into utility rebates: More financial incentives might be available from utility companies looking to encourage homeowners to go solar. Contact your local utility provider to learn rebate values and eligibility rules, so you can calculate your possible savings.
