How To Choose a Solar Company

Installing solar panels can cut your electricity costs and benefit the planet by reducing your carbon footprint. When determining whether a solar provider is a good fit for you, consider these key factors.

Check Licensing

Hiring a licensed solar installer is critical. This ensures that the work is done properly using the most up-to-date installation methods. A master electrician needs to supervise solar photovoltaic installations in New Hampshire. However, solar thermal installers need not be licensed plumbers unless a locality requires it.

Read Customer Reviews

Check consumer review platforms like Google Reviews, TrustPilot, and the Better Business Bureau (BBB) 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 3–5 solar companies for free, itemized quotes. The quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Switching to solar power can help decrease your energy expenses over time. Be sure to consider these aspects when judging the cost and value of solar panels.

  • Compare system purchase options: Homeowners may purchase solar panels upfront or finance payments over time with loans or leases. Be sure to check key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • Look into utility rebates: Some energy providers may provide additional discounts to motivate homeowners to adopt solar power. Check the requirements and the rebate amounts offered by your local electric provider to estimate the possible savings.
  • Research federal and state tax credits: A 26% federal solar tax credit on total system costs is available through 2032. Many states also have incentives. These credits offer substantial savings for solar customers.
