How To Choose a Solar Company

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

Check Licensing

Make sure you hire a licensed solar installer. This helps ensure that the work is done properly using current best installation practices. There are five different types of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn a license, a contractor must complete 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 TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's dependability and customer service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar installer that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Comparing several quotes helps you identify the most cost-effective option.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance warranties. The workmanship warranty covers any installation issues like cracks in the panels, poor wiring, or poor alignment. The output guarantee ensures an energy generation baseline. Strong warranties reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

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

  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states provide incentives, too. The credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or paid for over time through a lease or loan. Verify all terms when financing, such as payment schedule, fees, annual percentage rate (APR), and ownership implications.
  • Look into utility rebates: Some utility companies may provide additional discounts to motivate homeowners to adopt solar power. Check the qualification rules and rebate amounts offered by your local electric utility to estimate the possible savings.

Cost of Solar Installation in Fremont

The average Fremont homeowner will spend around $7,314 on a home solar system after federal tax refunds. Solar arrays in Fremont cost approximately $3,470 per kilowatt, with the average residential solar system being 3.0 kilowatts. A personalized estimate from a local solar provider will include costs for preliminary work, labor, and permit fees, and will account for your system's size, panel type, and capacity. Some homeowners prefer to lease solar panels to reduce upfront costs.
