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 evaluating if you want to go solar, consider these key factors for choosing an installer.

Check Licensing

Confirm that your solar installer is properly licensed. This helps ensure that the work is done properly using current installation best practices. There are five specific classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn a license, a contractor 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 TrustPilot, Google Reviews, the Better Business Bureau (BBB), and other review sites to see what past customers are saying about local solar installers. Detailed reviews on these platforms can help you evaluate a provider's reliability and customer service. Avoid providers with few or mainly poor reviews.

Compare Multiple Quotes

To find a solar company that fits your budget, ask for free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Looking at several quotes helps you identify the option that best fits your budget.

Ask About the Warranty

Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship guarantee covers any installation issues such as poor wiring, poor alignment, or cracks in the panels. The performance guarantee promises a specific energy output level. Strong warranties indicate that a solar installer trusts its installations.

Evaluate Financing and Incentives

Solar energy can help lower your electric bills over time. When evaluating the total price and value of solar panels, make sure to consider these factors.

  • Research federal and state tax credits: A 26% federal tax credit for the full solar system cost is available through 2032. Many states provide incentives, too. The credits can result in substantial savings for solar buyers.
  • Look into utility rebates: More rebates might be available from electric companies looking to encourage homeowners to install solar panels. Contact your local utility provider to learn rebate values and eligibility rules, so you can calculate your possible savings.
  • Compare system purchase options: Homeowners may purchase solar panels upfront or spread out payments over time with a lease or loan. Be sure to verify key details like fees, annual percentage rate (APR), payment schedule, and what ownership means when financing solar panels.

Cost of Solar Installation in Lathrop

Frequently Asked Questions About Solar in Lathrop, CA

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

With home solar PV, you can save money on your energy bill, lower your home's carbon footprint, and gain additional energy independence.

It depends on where you live and what type of panels you're installing. 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 significantly decrease 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 Lathrop, the average amount someone can save is $1,052 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.

You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. In perennially-sunny Lathrop, you could make enough from your solar panels to recoup your investment in 7.0 years per 5 kW of rated capacity at maximum.

Net metering is a power purchasing policy that allows solar energy system owners to receive bill credits or payments for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.

While solar energy is a great 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.

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