How To Choose a Solar Company

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

Check Licensing

Verify that your solar installer is properly licensed. This help guarantee 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 who install solar PV systems. Even if a contractor has an AES license, they may still need to subcontract plumbing, HVAC or electrical work.

Read Customer Reviews

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

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. The quotes should describe all costs and identify the exact solar parts included. Comparing several quotes can help you find the most cost-effective option.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help decrease your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.

  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also provide incentives. These credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed through a loan or lease. Check important financing details such as fees, annual percentage rate (APR), payment schedule, and ownership implications when financing your solar system.
  • Look into utility rebates: Some energy providers may provide additional discounts to incentivize homeowners to adopt solar power. Check the requirements and the rebate amounts offered by your local electric utility to determine your potential savings.
