How To Choose a Solar Company

Adopting solar power lets homeowners reduce utility bills while benefiting the planet by reducing your carbon footprint using clean energy. If you’re determining whether to go solar, consider these key factors for choosing an installer.

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done properly using current best installation practices. Vermont has a Solar System Specialist license for solar water heater installers. These license holders can set up and fix preheating or auxiliary solar devices up to specific advanced limits. For solar PV installations, contractor licensing requirements are limited and only include public buildings.

Read Customer Reviews

Check the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers are saying about local solar installers. 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

Call at least three solar companies for free, itemized quotes. These quotes should explain all costs and specify 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 alignment, cracks in the panels, 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

Solar energy is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • 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.
  • Look into utility rebates: Some utility companies may provide additional rebates to motivate homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local power company to determine the possible savings.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with loans or leases. Confirm key financing details like annual percentage rate (APR), fees, payment schedule, and ownership implications when financing solar panels.
