<p>[PROBLEMS] To provide a photovoltaic device capable of surely supplying power even if a cable connecting modules or circuit is disconnected. [MEANS FOR SOLVING PROBLEMS] A terminal box (3) is provided on a rear surface of a plurality of solar cell modules (2) constituting a solar cell module group (1). A plus connection terminal (4) and a minus connection terminal (5) are mounted on the side surface of the terminal box (3). Two cables come out from the terminal box (3). A plus connection terminal (8) is mounted on one (6) of the cables and a minus connection terminal (9) is mounted on the other cable (7). The plus connection terminal (8) of the solar cell module (2) is connected tot he plus connection terminal (4) of the adjacent solar cell module (2) while the minus connection terminal (9) is connected to the minus connection terminal (5) of the adjacent solar cell module (2). The plus connection terminal (8) of the last solar cell module (2) is connected to the plus connection terminal (4) of the solar cell module (2) and the minus connection terminal (9) of the last solar cell module (2) is connected to the minus connection terminal (5) of the first solar cell module (2), thereby completing the solar cell module group (1) of parallel connection in the closed loop.</p> |
