How To Choose a Solar Company

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

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done correctly using the most up-to-date installation methods. In Connecticut, a journeyman who meet minimum experience requirements can take an exam to become a licensed solar PV or thermal contractor. Once they're licensed, they'll need to sign up with the state's Clean Energy Fund, so that their customers can earn incentives.

Read Customer Reviews

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

Compare Multiple Quotes

Contact three to five solar companies to receive free, detailed quotes. Quotes should clearly explain all costs and specify the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help decrease your electric bills over time. When considering the total price and value of solar panels, make sure to consider these factors.

  • Compare system purchase options: Homeowners can pay for solar panels outright or finance payments over time with loans or leases. Be sure to check key details like payment schedule, annual percentage rate (APR), fees, and what ownership means when financing solar panels.
  • Look into utility rebates: Local power companies may have extra financial benefits to encourage homeowners to install solar panels. Review the qualification rules and rebate amounts with your local provider to figure out your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit on the full cost of solar systems is available through 2032. Many states also offer incentives. These credits can lead to substantial savings for solar buyers.
