How To Choose a Solar Company

Adopting solar power lets homeowners cut utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re determining whether to go solar, consider these key factors for choosing an installer.

Check Licensing

Verify that your solar installer is properly licensed. This ensures that the work is done properly using current best installation practices. There are five specific types 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

Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers say about local solar installers. Reviews can give you an idea of a company’s dependability and customer service. Avoid companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

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

Ask About the Warranty

Quality solar installations should have strong workmanship and performance warranties. A workmanship warranty 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 guarantees show that a company is confident in its work.

Evaluate Financing and Incentives

Installing solar panels can help lower your electric bills over time. When weighing the total price and value of solar panels, make sure to consider these factors.

  • Compare system purchase options: Solar panels may be paid for outright or financed over time with a loan or lease. Check key financing details like fees, payment schedule, annual percentage rate (APR), and ownership implications 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 add up to significant savings for solar buyers.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install solar panels. Check the requirements to qualify and the rebate values with your local electric company to find out what you could save.

Cost of Solar Installation in San Lorenzo

The cost of solar panels varies based on your system's capacity and the technology used. The average solar system in San Lorenzo has a capacity of 3.0 kilowatts. Homeowners in the area can expect to pay approximately $3,470 per kilowatt; the average San Lorenzo homeowners spends roughly $7,314 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower upfront costs.) A personalized quote from a local solar provider will account for things like the capacity, panel type, and size of the planned system, and should include prices for labor, permit fees, and preliminary work.

Frequently Asked Questions About Solar in San Lorenzo, CA

A solar photovoltaic (PV) system can generate power to run any electric system or appliance in your home. A more specific example is installing a solar heating system for your water.

There are many advantages of home solar energy. You can reduce emissions, qualify for tax benefits, and save money. With the right storage equipment, solar panels can also provide you with additional energy security and offer some protection from power outages.

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 hit peak performance until summer arrives.

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. San Lorenzo has extremely high daily sunlight levels, so you could recoup your investment in as little as 6.9 years per 5 kW of rated capacity.

Net metering is a type of "power purchase agreement." If your state or utility offers net metering, you can send the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

Solar panels are gaining in popularity 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.
