Benefits of Solar Energy

Solar energy comes with multiple advantages. Here are some highlights.

  • Lower energy bills: Sourcing some or all of your own power will cut power costs long-term. Plus, some states provide net metering programs that allow you to sell your surplus energy back to the grid, generating additional credits toward your energy bill.
  • Better energy independence: Photovoltaic solar panel systems with battery backups and storage systems operate through blackouts and emergencies, and you won't have to rely on the power grid for your safety and comfort.
  • Reduced carbon footprint: Utilizing solar is a surefire way to decrease your carbon footprint and home fossil fuel dependency.

How To Choose the Best Solar Company in Downers Grove

Choosing a company is the first step toward a well-oiled and valuable solar system. Make your choice based on the following key factors.

Licensing and Training

In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including home solar installers. You should also visit a company's website to learn about its private credentials. Two of the most respected are the Solar Heating Installer and PV Installation Professional certificates, awarded by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Downers Grove

The type of solar panels you choose decides how much electricity you can produce. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

If you want to charge an electric car or use your solar power in dark weather, you can pay extra for add-ons. By choosing the right components, you can make your system more productive and user-friendly. Not every solar company provides these additional features, so look for a provider that sells them if it's a priority for you.

A majority of Downers Grove homeowners opt for solar systems designed for five kilowatts (kW) of electrical capacity. These systems cost about $18,800 to set up, considering both parts and installation. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,248.21
Solar Polycrystalline$973.61
Thin-Film$569.19
Solar Battery$798.86
Solar Home EV Charger$2,995.71

Financing Solar Energy in Downers Grove

Choosing the correct financing plan will influence your overall solar system cost and expected savings. Common payment options include power purchase agreements, cash payments, leases, and loans. We recommend paying with cash or securing a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar panel incentives to minimize your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases let you use your panels for a set monthly rate, while PPAs let you pay only for the energy you use, much like an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Look for companies that offer multiple payment plans to find the right fit for your wallet.

The table below lists the average payback periods for different capacities of solar systems in Downers Grove.

A 26% federal solar tax credit applies to new residential solar equipment purchased through 2032. Further incentives may be available through local governments, usually in the form of rebates and special financing programs.
