How To Choose a Solar Company

Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when looking at local solar installers are as follows.

Check Licensing

Make sure you hire a licensed solar installer. This help guarantee that the work is done properly using current best installation practices. There are five specific classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn licensure, 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

Check Google Reviews, TrustPilot, 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. Stay away from companies with few or mainly poor reviews.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. A quote should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps you find the best option that fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar panels can help reduce your electricity costs in the long run. When evaluating solar panel's cost and value, be sure to weigh these considerations.

  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can add up to significant savings for solar buyers.
  • Look into utility rebates: Some energy providers may provide additional rebates to motivate homeowners to install solar panels. Check the requirements and the rebate amounts offered by your local electric provider to estimate your potential savings.
  • Compare system purchase options: Solar panels may be paid for upfront or financed over time through a loan or lease. Confirm all terms when financing, such as annual percentage rate (APR), fees, payment schedule, and ownership implications.

Frequently Asked Questions About Solar in Vacaville, CA

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

With home solar panels, you can save money on your energy bill, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.

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.

Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Vacaville, the average amount someone can save is $1,053 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.

While solar energy is an ideal option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, you could consider 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.

When it comes to 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. As for insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should speak with your accountant or insurance agent for information specific to your case.

Some frequently-used types of home solar panels in Vacaville include monocrystalline, polycrystalline and thin-film. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Talk with your local provider about the types of solar panels they work with.
