How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet by reducing your carbon footprint using renewable energy. Here are some key factors to consider when determining whether a solar installer is reliable.

Check Licensing

Make sure you hire a licensed solar installer. This ensures that the work is done properly using current installation best practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including solar installers.

Read Customer Reviews

Check consumer review platforms like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see feedback from past customers about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with installers that have no reviews or mostly negative ones.

Compare Multiple Quotes

Contact at least three solar companies to receive free, detailed quotes. Quotes should clearly outline all costs and specify the exact solar components included. Comparing multiple quotes helps identify the best value based on your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Installing solar panels can help reduce your electric bills over time. When evaluating the total price and value of solar panels, be sure to consider these factors.

  • Compare system purchase options: Solar panels can be purchased upfront or paid for over time through loans or leases. Verify all terms when financing, such as payment schedule, annual percentage rate (APR), fees, and ownership implications.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states provide incentives, too. The credits can lead to substantial savings for solar buyers.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to switch to solar power. Check the qualification criteria and rebate values with your local electric company to find out what you could save.

Cost of Solar Installation in Wheaton

In Wheaton, solar panels cost an average of $3,760 per kilowatt, with an average system size of 6.5 kilowatts. The typical Wheaton homeowner spends $17,196 on their solar array after federal tax refunds. An estimate from a local provider will factor in additional information reflecting your desired system's size, capacity, required preliminary work, and panel type. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

Frequently Asked Questions About Solar in Wheaton, 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 heater.

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

It depends on where you live and what type of panels you're installing. Since there's a moderate amount of snowfall in Wheaton, your best time to install solar panels is in the spring and fall.

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 Wheaton, the average amount someone can save is $943 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system once the payback period passes.

You might be pleasantly surprised at how short it takes to get a return on investment from your solar panels. The sun shines frequently in Wheaton, meaning your payback period could last 18.2 years per 5 kW of capacity on the high end.

Your recommended maintenance will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel four times a year. Your solar installation company might offer comprehensive plans where they'll do the maintenance for you.

Net metering is a type of "power purchase agreement." If your state or utility 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.
