How To Choose a Solar Company

Putting solar panels on your roof could reduce 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

Verify that your solar installer is properly licensed. This help guarantee that the work is done correctly 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 a license, a contractor 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 TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about 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

To find a solar company that fits your budget, get free, detailed quotes from 3–5 providers. The quotes should outline all costs and list the solar equipment included. Comparing several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar power can help decrease your electricity costs over time. When weighing solar panel's cost and value, be sure to weigh these considerations.

  • Compare system purchase options: Solar panels can be purchased upfront or financed over time through loans or leases. Verify all terms when financing, including payment schedule, fees, annual percentage rate (APR), and ownership implications.
  • 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 have incentives. These credits offer substantial savings for solar customers.
  • Look into utility rebates: More rebates might be available from local power companies looking to motivate homeowners to install solar panels. Contact your local utility provider to learn rebate values and qualification criteria, so you can calculate your possible savings.

Frequently Asked Questions About Solar in Cupertino, CA

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

There are a number of benefits to home solar energy. You can qualify for tax benefits, reduce emissions, and raise your property values. With the right storage equipment, solar panels can also give you additional energy security and offer some protection from power outages.

It depends on your location and the kind of panels you plan to use. With the winter months in California being very mild, you have a wide time window to install your panels, though they won't reach 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 Cupertino amount to $961.

Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the average sunlight in your area, their rated capacity, and the rate your utility charges per kilowatt of power. Cupertino has extremely high daily sunlight levels, so you could recoup your investment in as little as 7.5 years per 5 kW of rated capacity.

Regarding taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. Regarding insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should consult with your accountant or insurance agent for information specific to your case.

The most common types of home solar panels in Cupertino include monocrystalline, thin-film and polycrystalline. Monocrystalline panels are balanced and efficient, while thin-film and polycrystalline panels pair good performance with greater upfront value. Talk with your local provider about which solar panels they work with.

Solar panels are becoming more relevant than ever 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.
