How To Choose a Solar Company

Installing solar panels can cut your electricity costs and benefit the planet by reducing your carbon footprint. When evaluating if a solar provider is right for you, consider these key factors.

Check Licensing

It's imperative that your solar installer has the proper licensing. This helps ensure 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. To earn licensure, an installer must take a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams.

Read Customer Reviews

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

Compare Multiple Quotes

Get free, detailed quotes from three to five solar companies. The quotes should outline all costs and identify the solar parts included. Looking at several quotes can help you find the option that best fits your budget.

Ask About the Warranty

Quality solar installations should include strong workmanship and performance guarantees. A workmanship guarantee addresses any installation defects (such as poor wiring, poor alignment, or cracks in the panels), while a performance warranty ensures a certain level of energy production. Strong warranties show that a company is confident in its work.

Evaluate Financing and Incentives

Switching to solar power can help reduce your energy expenses. Be sure to consider these aspects when judging the cost and value of solar panels.

  • Compare system purchase options: Solar panels can be purchased upfront or financed through loans or leases. Confirm 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 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: Local power companies may have extra discounts to incentivize homeowners to adopt solar power. Review the requirements to qualify and the rebate amounts with your local provider to figure out your potential savings.

Cost of Solar Installation in Santa Clara

Santa Clara homeowners typically spend about $7,249 on home solar systems after federal tax refunds.

Some homeowners prefer to lease solar panels to reduce upfront costs.
