How To Choose a Solar Company

Installing solar panels can reduce your electricity costs and benefit the planet by reducing your carbon footprint. When determining whether a solar provider is a good fit for you, consider these key factors.

Check Licensing

It's important to hire a licensed solar installer. This ensures that the work is done properly using current best installation practices. There are five specific classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn licensure, 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 the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see feedback from past customers on 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

Contact 3–5 solar companies for 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

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

  • Compare system purchase options: Solar panels may be paid for outright or financed over time with loans or leases. Verify key financing details like annual percentage rate (APR), fees, payment schedule, and ownership implications when choosing to finance solar panels.
  • 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 customers.
  • Look into utility rebates: More rebates might be available from local power companies looking to encourage homeowners to install solar panels. Contact your local utility provider to find out rebate values and eligibility rules, so you can calculate your possible savings.

In Los Altos, solar panels cost an average of $3,470 per kilowatt, with an average system size of 3.0 kilowatts. The typical Los Altos homeowner spends $7,249 on their solar array after federal tax refunds.
