How To Choose a Solar Company

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

Check Licensing

Verify that your solar installer is properly licensed. This help guarantee that the work is done properly using the most up-to-date installation methods. There are five distinct levels 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 experience as an apprentice or journeyman, and pass written exams.

Read Customer Reviews

Check review sites like Google Reviews, the Better Business Bureau (BBB), and TrustPilot to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. A quote should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the most cost-effective option for your budget.

Ask About the Warranty

Quality solar installations should have comprehensive workmanship and performance warranties. The workmanship guarantee covers any installation problems such as cracks in the panels, poor wiring, or poor alignment. The performance warranty ensures a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar energy can help decrease your electricity costs in the long run. When weighing solar panel's cost and value, be sure to consider these considerations.

  • Compare system purchase options: Solar panels can be purchased outright or financed through a loan or lease. Confirm important financing details such as fees, payment schedule, annual percentage rate (APR), and ownership implications when financing your solar system.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install solar panels. Check the qualification criteria and rebate values with your local power company to find out what you could save.
  • 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.

Cost of Solar Installation in Brentwood

In Brentwood, solar panels cost an average of $3,470 per kilowatt, with an average system size of 3.0 kilowatts. The typical Brentwood homeowner spends $7,395 on their solar array after federal tax refunds. An estimate from a local provider will take into account additional information reflecting your desired system's required preliminary work, size, capacity, and panel type. In some cases, homeowners may prefer to lease solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Brentwood, CA

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

With home solar panels, 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 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 hit peak performance until summer arrives.

Of course. The grid in Brentwood 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.

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 Brentwood amount to $1,053.

The specific required maintenance steps will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel once a quarter. Your solar installation company might offer comprehensive plans where they'll do the maintenance on your behalf.

Although solar energy is an ideal option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, a contractor might recommend other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still lower your emissions and could still qualify for distributed generation or other money-saving programs.

Absolutely. Solar panels exist independently from the power grid in Brentwood and will continue to generate power even if the grid is having problems. Keep in mind, however, that a solar system won't take you through a nighttime outage if you don't have a storage system. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.
