How To Choose a Solar Company

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

Check Licensing

Verify that your solar installer is properly licensed. This help guarantee that the work is done properly using current best installation practices. There are five specific 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 review sites like TrustPilot, the Better Business Bureau (BBB), and Google Reviews to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and customer service. Use caution with companies that have no reviews or mostly negative ones.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. A quote should outline all costs and list the solar equipment included. Reviewing multiple quotes helps identify the most cost-effective option for your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help reduce your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.

  • Compare system purchase options: Solar panels can be purchased outright or financed through leases or loans. Review important financing details such as fees, annual percentage rate (APR), payment schedule, and ownership implications when financing your solar system.
  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to the full system cost is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar buyers.
  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to switch to solar power. Check the requirements to qualify and the rebate values with your local electric company to determine what you could save.
