How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when deciding if a solar installer is reliable.

Check Licensing

Hiring a licensed solar installer is critical. This ensures that the work is done properly using the most up-to-date installation methods. There are five distinct types 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 TrustPilot, the Better Business Bureau (BBB), Google Reviews, and other review sites to see what past customers are saying about local solar installers. Detailed reviews on these platforms can help you assess a provider's reliability and customer service. Be wary of companies with few or mainly poor reviews.

Compare Multiple Quotes

Contact 3–5 solar companies for free, detailed quotes. Quotes should clearly explain all costs and specify the exact solar components included. By comparing multiple quotes, you can identify the most cost-effective option for you.

Ask About the Warranty

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

Evaluate Financing and Incentives

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

  • Look into utility rebates: More financial incentives might be available from electric companies looking to motivate homeowners to install solar panels. Contact your local utility provider to find out rebate values and qualification criteria, so you can calculate your possible savings.
  • Compare system purchase options: Homeowners can pay for solar panels outright or spread out payments over time with loans or leases. Be sure to verify key details like annual percentage rate (APR), payment schedule, fees, and what ownership means when financing solar panels.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also offer incentives. The credits can result in significant savings for solar buyers.

Frequently Asked Questions About Solar in Los Altos Hills, CA

Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance that uses electricity. In the smallest case, you can use a solar water heating system.

With home solar energy, you can recoup the cost of the system over time, lower your property's emissions, and be better prepared if there's an outage to the local grid.

It depends on where you live and what type of panels you're installing. With the winter months in California being very mild, you have a lengthy window to install your panels, though they won't reach peak performance until summer arrives.

Absolutely. The grid in Los Altos Hills already uses a large share of renewable energy sources, and you may be able to sell your excess generated energy to your utility for additional cost savings.

Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Los Altos Hills, the average amount someone can save is $999 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.

While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.

Ultimately, the answer will depend on your specific situation. You can take advantage of a federal tax credit of up to 30% of the system's cost, as well as state or local incentives depending on where you are. As for insurance, you'll need to let your insurer know about your new solar panels. Your premium may increase due to added property values, but you'll have peace of mind if a covered event happens to the system.

Solar panels are becoming more popular for their low upkeep costs and high efficiency under a variety of conditions. Depending on how much sunlight your property receives, you may find they're the best performing source of renewable energy compared to others.
