How To Choose a Solar Company

Installing solar panels can reduce your electricity costs and benefit the planet by reducing your carbon footprint. When deciding if a solar provider is a good fit for you, consider these key factors.

Check Licensing

Confirm that your solar installer is properly licensed. This helps ensure that the work is done properly 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. To earn a license, an installer 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 the Better Business Bureau (BBB), Google Reviews, and TrustPilot to find out what previous customers are saying about local solar providers. Reviews can give you an idea of a company’s trustworthiness and customer service. Be cautious of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. The quotes should describe all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the most cost-effective option for your budget.

Ask About the Warranty

Quality solar installations should include strong workmanship and performance guarantees. A workmanship warranty addresses any installation defects (such as poor alignment, poor wiring, or cracks in the panels), while a performance warranty ensures a certain level of energy production. Strong guarantees demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

Solar is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • Look into utility rebates: Local power companies may have extra discounts to motivate homeowners to go solar. Review the requirements to qualify and the rebate amounts with your local provider to calculate your potential savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also provide incentives. These credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased outright or financed through leases or loans. Review important financing details such as annual percentage rate (APR), payment schedule, fees, and ownership implications when financing your solar system.

Cost of Solar Installation in Lafayette

The cost of solar panels varies based on system capacity and the technology being used. The typical Lafayette solar array has a capacity of 3.0 kilowatts. Homeowners in the area should expect to pay approximately $3,470 per kilowatt; the average Lafayette homeowners spends roughly $7,395 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower their upfront costs.) A personalized quote from a local solar installer will account for factors such as the size, panel type, and capacity of the planned system, and should include fees for preliminary work, permit fees, and labor.

Frequently Asked Questions About Solar in Lafayette, 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 a number of benefits to home solar energy. You can raise your property values, qualify for tax benefits, and save money. With the right storage equipment, solar panels can also offer you further energy independence and offer some protection from power outages.

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 a wide time window to install your panels, though they won't achieve 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 rate your utility charges per kilowatt of power, the average sunlight in your area, and their rated capacity. Lafayette has extremely high daily sunlight levels, so you could recoup your investment in as little as 7.0 years per 5 kW of rated capacity.

The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should inspect your panels for damage and clean them regularly. Full-service solar contractors in the Lafayette area offer multipoint maintenance plans to help you make the most of your panels and keep them healthy for as long as possible.

Solar panels are gaining traction 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.
