How To Choose a Solar Company

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

Check Licensing

Verify that your solar installer is properly licensed. This helps ensure that the work is done correctly using current installation best practices. There are five specific levels of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn licensure, a contractor 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 TrustPilot, the Better Business Bureau (BBB), and Google Reviews 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 barely any reviews or mostly negative ones.

Compare Multiple Quotes

Call at least three solar companies for free, itemized quotes. These quotes 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 strong workmanship and performance guarantees. A workmanship warranty addresses any installation defects (such as poor wiring, poor alignment, or cracks in the panels), while a performance guarantee ensures a certain level of energy production. Strong warranties show that a company is confident in its work.

Evaluate Financing and Incentives

Solar can help you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

  • 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 eligibility rules, so you can determine your possible savings.
  • Compare system purchase options: Homeowners may purchase solar panels upfront or finance payments over time with leases or loans. Be sure to confirm key details like fees, annual percentage rate (APR), payment schedule, and what ownership means 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 provide incentives. The credits can add up to significant savings for solar buyers.

Cost of Solar Installation in Fairfield

Fairfield homeowners typically spend about $7,414 on home solar systems after federal tax refunds.

Some homeowners prefer to lease solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Fairfield, CA

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. More specifically, you can install a solar water heating system.

There are many advantages of home solar energy. You can reduce emissions, raise your property values, and qualify for tax benefits. With the right storage equipment, solar panels can also provide you with 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.

Absolutely. The grid in Fairfield 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.

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

Solar panels are on par with other forms of renewable energy. They have low maintenance costs and today's systems can stand up to the worst conditions.
