Internal electrical connections used for a photovoltaic module

摘要

It is an object of the present invention to provide a photovoltaic module capable of reducing an area occupied by interconnectors. The photovoltaic module of the present invention comprises light-transmitting substrate, strings (40) including a plurality of solar cells (11) interconnected through tab connector (16), and rear surface member. A plurality of the strings (40) is electrically connected through interconnectors (41) (42) (43) (44) (45) and arranged on a rear surface side so as not to overlap each other. The photovoltaic module is sealed with a sealant between the light-transmitting substrate and the rear surface member.
