What ownership options are available?
Solar companies typically offer a few different ownership options: direct ownership, lease, or Purchase Power Agreement (PPA). A PPA consists of the solar company owning the array and selling you the electricity it produces. GU customers must own or finance the system; third party electricity sales to municipal utility customers (such as a PPA) are not allowed per CT state law.
