How To Choose a Solar Company

Going solar can be a great way to reduce electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some key factors to consider when deciding if a solar installer is trustworthy.

Check Licensing

Confirm that your solar installer is properly licensed. This ensures that the work is done properly using current best installation practices. There are five different levels of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. For a contractor to earn a license, an installer must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams.

Read Customer Reviews

Check consumer review platforms like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with installers that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Contact at least three solar companies to receive free, detailed quotes. Quotes should clearly outline all costs and list the exact solar components included. By comparing multiple quotes, you can identify the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar panels can help decrease your electricity costs in the long run. When evaluating solar panel's cost and value, be sure to weigh these considerations.

  • Compare system purchase options: Solar panels may be paid for upfront or financed over time through a lease or loan. Review all terms when financing, such as annual percentage rate (APR), fees, payment schedule, and ownership implications.
  • 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 result in substantial savings for solar buyers.
  • Look into utility rebates: More discounts might be available from utility companies looking to motivate homeowners to install solar panels. Contact your local utility provider to learn rebate values and qualification criteria, so you can calculate your possible savings.
