How To Choose a Solar Company

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

Check Licensing

Hiring a licensed solar installer is critical. This helps ensure that the work is done correctly using the most up-to-date installation methods. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including residential solar contractors.

Read Customer Reviews

Check the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers have to say about local solar installers. Detailed reviews on these platforms can help you assess a provider's reliability and customer service. Be wary of providers with few or mainly poor reviews.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. These quotes should outline all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the option that aligns with your budget.

Ask About the Warranty

Top-notch solar installations should include strong workmanship and performance warranties. A workmanship warranty covers installation issues, such as poor wiring, cracks in the panels, or poor alignment. A performance guarantee ensures a minimum energy output. Comprehensive warranties indicate that a solar company believes in its work.

Evaluate Financing and Incentives

Solar energy can help decrease your energy expenses over time. Be sure to weigh these aspects when judging the cost and value of solar panels.

  • Look into utility rebates: Local power companies may have extra financial benefits to encourage homeowners to install solar panels. Review the qualification rules and rebate amounts with your local provider to figure out 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 offer incentives, too. The credits can result in substantial savings for solar buyers.
  • Compare system purchase options: Homeowners can pay for solar panels upfront or finance payments over time with loans or leases. Be sure to confirm key details like payment schedule, annual percentage rate (APR), fees, and what ownership means when financing solar panels.

Frequently Asked Questions About Solar in Lake Zurich, IL

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.

There are many benefits to home solar energy. You can raise your property values, qualify for tax benefits, and reduce emissions. With the right storage equipment, solar panels can also offer you further energy independence and offer some protection from power outages.

Of course. Lake Zurich uses an even mixture of solar energy and conventional power sources. While your panels at home will save you money and lower your home's individual emissions, you'll still benefit from access to the local grid.

Your payback period is the time to earn a net profit from 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. Lake Zurich gets quite a bit of sunlight per day, so an average payback period could last up to 18.4 years per 5 kW of capacity.

While solar energy might not be the best performing choice for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.

Solar panels are becoming more popular for their high efficiency and low maintenance costs. Depending on how much sunlight your property receives, you may find they're the best performing source of renewable energy compared to others.
