How To Choose a Solar Company

Going solar can be a great way to lower electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when determining whether a solar installer is reliable.

Check Licensing

It's important to hire a licensed solar installer. This ensures that the work is done correctly using the most up-to-date installation methods. There are five specific types of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. For a contractor to earn a license, an installer must take a highly comprehensive educational series, gain four years of field experience, and pass written exams.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with providers that have hardly any reviews or mostly negative ones.

Compare Multiple Quotes

Contact at least three solar companies to receive free, detailed quotes. Quotes should clearly outline all costs and specify the exact solar components included. Comparing multiple quotes helps identify the option that best fits your budget.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance guarantees. A workmanship warranty covers 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 warranties demonstrate a company's confidence 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.

  • Look into utility rebates: Some energy providers may provide additional discounts to encourage homeowners to adopt solar power. Check the eligibility criteria and rebate amounts offered by your local electric provider to determine the possible savings.
  • Compare system purchase options: Solar panels can be purchased outright or financed over time with a lease or loan. Confirm key financing details like payment schedule, fees, annual percentage rate (APR), and ownership implications when choosing to finance solar panels.
  • Research federal and state tax credits: A 26% federal solar tax credit on total system costs is available through 2032. Many states also have incentives. These credits provide substantial savings for solar customers.

Frequently Asked Questions About Solar in Foster City, CA

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. If you don't want to use solar power for your entire home, you can install a solar water heating system.

With home solar PV, you can save money on your energy bill, 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 the kind of panels you plan to use. With the winter months in California being very mild, you have significant leeway to install your panels, though they won't hit peak performance until summer arrives.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Foster City amount to $1,053.

Yes, solar panels can still provide you with energy during a grid outage. To ensure that your solar system is able to keep working during a power outage, make sure to choose a quality solar provider and look for a solar system that includes a battery backup.

The answer depends on your specific needs and goals. In most cases, monocrystalline solar panels are the most efficient for homes in Foster City. However, if lowering cost is your top priority, then you could thin-film or polycrystalline solar panels. When selecting a solar company, make sure to ask about the different types of solar panels a contractor offers and the benefits and drawbacks of each.
