Installing Solar Across Illinois

We are extremely proud of our Illinois roots, where we have a long-standing history of installing solar energy systems for residential, commercial, and utility-scale projects. With a reputation for quality installation, expertise, and five-star service, our team’s design and installation of solar energy systems started in the heart of the Midwest.

Solar in Illinois

Illinois has experienced significant growth in solar power installations, and we’re excited to be a renewable energy partner in the state. According to the Solar Energy Industries Association (SEIA), the state's solar capacity increased from just nine megawatts (MW) in 2015 to over 1,750 MW by the end of 2020.1 We’re proud to be a service provider in the first Midwest state to set a bold goal to reach 100% renewable energy by 2050.1 *

Opportunities for Illinoisans to Save With Solar*

  • Claim a Credit on Your Federal Income Taxes

    Taxpayers may be able to claim a tax credit on their federal tax return of 30% for qualified expenses on a solar system providing electricity to their home. Business taxpayers may qualify for a similar tax credit of 30% or more on a solar system they own. Consult your tax advisor to determine whether this credit is available to you and for what amount.
  • Earn Credits for Excess Energy Your System Produces

    Full retail rate net metering may provide customers with credits for the excess generated energy from their solar system. If your solar system produces more energy than you’re using, you may get credits applied to your monthly electricity bill at the discretion of your utility provider.2 Net metering can vary, depending on your utility provider.
  • Save With Other State and Local Incentives

    Illinois is a great place to live when it comes to going solar! Utilities and local municipalities may offer additional solar incentives that property owners can take advantage of to save even more. Depending on your situation, here are some of the incentives and programs you may qualify for:

    • Solar Renewable Energy Credits (SRECs)
    • Illinois Solar for All (ILSFA) Program

    *Consult your tax advisor to determine which credits and incentives apply to your situation.

Steps to Solar



During this meeting, we’ll share details about your system and answer any questions you may have about your project and solar energy.



Our site surveyor will visit to take precise measurements – and share them with our design team to help with the completion of your system design.



Along with a design packet and approval from a licensed structural engineer, we send required documents to your municipality for a building permit, which is granted at the discretion of the municipality, or authority having jurisdiction (AHJ).3



Once permitting is approved, we’ll get your installation scheduled. Most residential installations take from one to three days – and we’ll show you around the system once installation is complete.

Installations Around Illinois

Our Illinois teams can provide a full range of solar services – from design to completion and beyond. Our expertise extends to the installation and maintenance of residential, commercial, and agricultural solar systems, as well as additional enhancements such as battery storage.
