Connecticut is one of the fastest growing of the smaller states in the solar industry. This success comes after the state launched the Connecticut Property Assessed Clean Energy (C-PACE) program to offer property assessed clean energy financing and program services to municipalities and commercial property owners throughout Connecticut. This unique program will serve as a model for other states to follow.
