How To Choose a Solar Company

Adopting solar power lets homeowners reduce utility bills while benefiting the planet 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 help guarantee that the work is done correctly using current installation best practices. In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including residential solar contractors.

Read Customer Reviews

Look at review platforms such as TrustPilot, the Better Business Bureau (BBB), and Google Reviews to find out what previous customers have to say about local solar providers. Reviews can give you an idea of a company’s reliability and customer service. Avoid companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

To find a solar installer that works with your budget, ask for free, detailed quotes from three to five providers. The quotes should outline all costs and list the solar equipment included. Looking at several quotes helps you identify the most cost-effective option.

Ask About the Warranty

High-quality solar installations should include robust workmanship and performance warranties. The workmanship guarantee covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output guarantee ensures an energy generation baseline. Strong warranties reflect a solar provider's faith in its installations.

Evaluate Financing and Incentives

Switching to solar power can help decrease your energy expenses. Be sure to consider these aspects when judging the cost and value of solar panels.

  • Research federal and state tax credits: A 26% federal solar tax credit on the full system cost is available through 2032. Many states also have incentives. These credits provide substantial savings for solar buyers.
  • Look into utility rebates: Local power companies may have extra rebates to encourage homeowners to adopt solar power. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • Compare system purchase options: Solar panels may be paid for upfront or financed over time with leases or loans. Check key financing details like annual percentage rate (APR), payment schedule, fees, and ownership implications when financing solar panels.

Frequently Asked Questions About Solar in Markham, IL

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.

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 your location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Markham, 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 Markham, the average amount someone can save is $904 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.

Your payback period is the time to earn a net profit from your solar panels. It will vary based on their rated capacity, the average sunlight in your area, and the rate your utility charges per kilowatt of power. Markham gets quite a bit of sunlight per day, so an average payback period could last up to 18.6 years per 5 kW of capacity.

Your recommended maintenance will vary based on the type of solar panels you have. At a minimum, you should clean and inspect each panel four times a year. Your solar installer might offer comprehensive plans where they'll do the maintenance on your behalf.

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