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.

An improved roofing system including a batten assembly comprising support battens and clips. The clips are made of metal wire having one portion shaped to retain roof outer coverings and a further portion shaped to secure the clip to the batten by spring torsion force of part of the clip acting against the batten.

Metal roofing includes metal roof-covering sheets or tiles having apertures along longitudinal end edges for coupling a pair of the sheets in an overlapping condition. One fastening arrangement comprises a fastener having a shaft extending in a longitudinal direction and fastening features at longitudinally spaced positions along the shaft. The fastening features may comprise a fastening peg or an opening receiving a fastening member therethrough. The pegs and openings may be combined in such a manner that at least two of the features cooperate with the apertures of the respective sheet in opposing transverse directions so as to longitudinally offset the apertures in the overlapping condition. Another fastening arrangement comprises a roof-covering sheet locating fastenings pegs which are spaced inward of the apertures in a longitudinal direction of the sheet so as to form the longitudinal offset between the respective sets of apertures.
