Donate to CT Solar Challenge

Help CT Solar ChallengeCT Solar Challenge is a 501(c)(3) non-profit that helps communities become energy independent through collaborative solar installations.

We are an educational resource presenting workshops about the benefits and ease of installing solar energy. We also connect home and business owners with quality solar installers.

Help Make CT 100% Solar

Our goal is to have free solar installations for every municipal building in Connecticut. When residents work with CT Solar to have solar installed on their home or business, the kilowatt hours they save accrue to earn solar systems for their town halls and schools.

The effort of community leaders working with local solar installers has helped to generate approximately 2.3 MEGAWATTS of new residential solar, and more than doubled the amount of solar deployed in each participating town.
