How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

It's imperative that your solar installer has the proper licensing. This helps ensure that the work is done properly using the most up-to-date installation methods. Since 2012, the Virginia Department of Professional and Occupational Regulation has issued Alternative Energy Systems (AES) licenses to contractors installing solar PV systems. Even if a contractor has an AES license, they may still need to subcontract electrical, HVAC or plumbing work.

Read Customer Reviews

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

Compare Multiple Quotes

Call at least three solar companies for free, itemized quotes. The quotes should outline all costs and list the solar equipment included. Reviewing multiple quotes helps you find the best option that fits your budget.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance warranties. The workmanship guarantee covers any installation problems such as cracks in the panels, poor wiring, or poor alignment. The performance guarantee promises a specific energy output level. Strong warranties indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar 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: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can add up to significant savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed over time with a lease or loan. Verify key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when choosing to finance solar panels.
  • Look into utility rebates: Local electric providers may offer additional rebates to encourage homeowners to switch to solar power. Check the requirements to qualify and the rebate values with your local power company to determine what you could save.
