A modular assembly of solar panels is held together in a rigid fashion through the use of two J-channels arranged on either side thereof in oppositely facing directions. Brackets hold these J-channels to flanges on the underside of the solar panels. In the argot of solar panel installation, the J-channels extend in the north-south direction. Between each solar panel there is disposed a liquid collecting pan extending in the east-west direction. This collecting pan also acts as a clip providing both a structural and electrical connection between adjacently disposed solar panels in a column assembly which is rendered capable of installation as a single unit from the ground.
