How To Choose a Solar Company

Putting solar panels on your roof could reduce your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee 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 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 evaluate a company's dependability and level of service. Use caution with providers that have no 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 identify the most cost-effective option for your budget.

Ask About the Warranty

Top-notch solar installations should have strong workmanship and performance warranties. A workmanship guarantee covers installation issues, such as poor alignment, cracks in the panels, or poor wiring. A performance warranty guarantees a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.

Evaluate Financing and Incentives

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

  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also offer incentives. The credits can result in significant savings for solar buyers.
  • Look into utility rebates: Local power companies may have extra financial benefits to encourage homeowners to go solar. Review the requirements to qualify and the rebate amounts with your local provider to calculate your potential savings.
  • Compare system purchase options: Solar panels may be paid for upfront or financed over time with loans or leases. Confirm key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when financing solar panels.
