Image Number 2 for United States Patent #5180442.
Photovoltaic solar modules are efficiently assembled into an array by the use of a lattice and mounting-conducting electrodes. The lattice consists of parallel conducting strips spaced apart by a distance equal to the width of a module, secured to a supporting frame. The electrodes are attached to busbars fabricated on the modules, which are environmentally sealed with the ends of the electrodes protruding. The protruding ends fit into slots punched into the conducting strips, both securing the modules and electrically connecting them to the lattice. A large array of series and parallel connected modules can thus be formed.
