How To Choose a Solar Company

Installing solar panels can cut 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

Confirm that your solar installer is properly licensed. This help guarantee that the work is done properly using the most up-to-date installation methods. Tennessee requires any solar energy project valued at $25,000 or higher to be overseen by a licensed "prime contractor." The prime contractor is responsible for hiring licensed subcontractors as the project demands. Even if a project doesn't cross the $25,000 value threshold, you will still need a master electrician or electrical journeyman to handle permit work.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar company that fits your budget, ask for free, detailed quotes from 3–5 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

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

Evaluate Financing and Incentives

Solar energy can help decrease your electricity costs over time. When evaluating solar panel's cost and value, be sure to weigh these considerations.

  • Look into utility rebates: More rebates might be available from electric companies looking to motivate homeowners to go solar. Contact your local utility provider to find out rebate values and qualification criteria, so you can calculate your possible savings.
  • Compare system purchase options: Homeowners may purchase solar panels upfront or finance payments over time with a loan or lease. Be sure to check key details like payment schedule, annual percentage rate (APR), fees, and what ownership means when financing 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 have incentives. These credits offer substantial savings for solar customers.
