    "The Best Solar Option Available, You Won't Regret!"

    Reviewed Mar 25, 2021

    Windfree Solar Co was an absolute delight to work with. I was referred by a friend and was glad I was. They were on top of everything and available to answer any questions I had throughout the process. Adam took extra time to ensure I understood each step and made sure I completed everything I needed to do on my end. It was completely seamless from start to finish. I received my first tax refund without any hassle! The panels were installed professionally and look great against my roof. So leaks or issues at all.. I have since recommended them to all my friends and family who own a home!

  • "Windup with Windfree"

    Reviewed Mar 01, 2021

    Hi to all. I recommend Windfree as a thorough rooftop solar provider. We live in Oak Park with a good size roof and little tree cover. The Team worked diligently through December to install 18 panels before the end of the year. Thank you Windfree for getting it done--best Christmas present ever.

  • "9KW system installed"

    Reviewed Nov 12, 2018

    After the initial teething issues for delays in installation, Windfree team did a good job in completing the project. As of now the system is installed and producing power. Windfree team is working to complete the SREC submissions and Net-metering requirements. They have been very responsive.

    Doug and Windfree are easy to work with, honest, reliable and responsive. Service is outstanding. When our array was struck by lightning, Windfree responded almost instantly and got us running again. Windfree obviously has excellent relationships with its suppliers who also responded to provide the necessary parts and assistance immediately.
