How To Choose a Solar Company

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

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done properly using the most up-to-date installation methods. Massachusetts requires new solar PV systems in the Commonwealth to be installed by a licensed electrician and new solar water heaters to be installed by a construction supervisor.

Read Customer Reviews

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

Compare Multiple Quotes

To find a solar installer that fits your budget, get free, detailed quotes from at least three providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help decrease your energy expenses. Be sure to evaluate these aspects when determining the cost and value of solar panels.

  • 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 offer incentives. These credits offer substantial savings for solar customers.
  • Compare system purchase options: Homeowners can pay for solar panels upfront or finance payments over time with leases or loans. Be sure to verify key details like annual percentage rate (APR), payment schedule, fees, and what ownership means when financing solar panels.
  • Look into utility rebates: Some utility companies may provide additional discounts to incentivize homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local power company to determine your potential savings.
