Abstract: A roof integrated photovoltaic (RIPV) system has a plurality of solar tiles that are mounted to a roof. The tiles may be mounted using a metal batten and hanger system or some other attachment system. Each tile has an electrical edge junction extending rearwardly from its top edge. The edge junction is coextensive with or contains the plane of the solar tile and may be slightly thicker than the solar tile. Sockets on opposed ends of the edge junction receive plugs of electrical cables for interconnecting the array of solar tiles together electrically. The edge junctions provide for a low profile installation that mimics the appearance of a traditional roofing tile such as a slate tile. The slightly thicker edge junctions may raise solar tiles of one course above the surfaces of solar tiles of a next lower course to provide ventilation for the RIPV array and to provide accommodating space for system wiring.
