How To Choose a Solar Company

Adopting solar power lets homeowners reduce 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

Make sure you hire a licensed solar installer. This ensures that the work is done properly using current best installation practices. There are five distinct classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. For a contractor to earn a license, an installer must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams.

Read Customer Reviews

Check TrustPilot, Google Reviews, the Better Business Bureau (BBB), and other review sites to see what past customers have to say about local solar providers. Detailed reviews can help you assess a provider's trustworthiness and customer service. Be wary of companies with few or mainly poor reviews.

Compare Multiple Quotes

Get free, detailed quotes from 3–5 solar companies. A quote should list all costs and identify the exact solar parts included. Looking at several quotes can help you find the option that best fits your budget.

Ask About the Warranty

Quality solar installations should include strong workmanship and performance warranties. A workmanship warranty covers any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance warranty ensures a certain level of energy production. Strong warranties show that a company is confident in its work.

Evaluate Financing and Incentives

Switching to solar power 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 utility companies may provide additional rebates to encourage homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local electric utility to determine the possible savings.
  • Research federal and state tax credits: A 26% federal tax credit on the full cost of solar systems is available through 2032. Many states also offer incentives. These credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time through a lease or loan. Review all terms when financing, including fees, payment schedule, annual percentage rate (APR), and ownership implications.

Cost of Solar Installation in San Diego

The average San Diego homeowner will spend around $6,837 on a home solar system after federal tax refunds. Solar arrays in San Diego cost roughly $3,470 per kilowatt, with an average size of 2.8 kilowatts. An estimate from a local solar provider will include costs for preliminary work, labor, and permit fees, and will account for your system's capacity, panel type, and size. Some homeowners prefer to lease their solar panels in order to reduce upfront costs.

Frequently Asked Questions About Solar in San Diego, CA

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

There are many benefits to 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 your location 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 San Diego amount to $922.

You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. In perennially-sunny San Diego, you could make enough from your solar panels to recoup your investment in 7.4 years per 5 kW of rated capacity at maximum.

The type of solar panels you have will have specific maintenance steps to follow. Regardless of type, you should clean your panels regularly and inspect them for damage. Many solar contractors in the San Diego area offer comprehensive maintenance plans to help you keep your panels healthy and make the most of your system.

While solar energy might not be the best performing choice for some in dark or wet areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could 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.

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.
