Solar module

Abstract

A solar module is provided which has improved durability. A third wiring member ( 32 a ) includes a first portion ( 32 a 1 ), a second portion ( 32 a 2 ), and a third portion ( 32 a 3 ). In the first portion ( 32 a 1 ), metal foil ( 52 ) faces a solar cell ( 20 ). The first portion ( 32 a 1 ) is electrically connected to the solar cell ( 20 ). The second portion ( 32 a 2 ) is arranged on the solar cell ( 20 ) with the metal foil ( 52 ) facing the side opposite to the solar cell ( 20 ). The third portion ( 32 a 3 ) connects the first portion ( 32 a 1 ) and the second portion ( 32 a 2 ). A first wiring member ( 32 b ) electrically connects the second portions ( 32 a 2 ) of adjacent solar cell strings ( 10 ) to each other. The solar module ( 1 ) also includes an insulating sheet ( 60 ). The insulating sheet ( 60 ) is arranged between the first wiring member ( 32 b ) and the solar cell ( 20 ).

1 - 4 . (canceled) 
     
     
         5 . A solar module comprising:
 a first solar cell string, a second solar cell string, and a third solar cell string arranged in a first direction;   an extraction electrode of metal foil connected electrically to the first solar cell string and drawn to the outside of the solar module; and   a first wiring member of metal foil electrically connecting the second solar cell string and the third solar cell string, wherein   each of the first, second and third solar cell strings comprises:
 solar cells arranged in a second direction inclined with respect to the first direction, the solar cells including a terminal solar cell located at an end of the solar cells in the second direction; 
 a second wiring member bonded to end portions of adjacent solar cells to electrically connect the adjacent solar cells to each other; and 
 a third wiring member having resin film and metal foil arranged on the resin film, and electrically connected to an end portion of the terminal solar cell in the second direction, 
   the third wiring member comprises:
 a first portion connected electrically to the terminal solar cell with the metal foil facing the terminal solar cell; 
 a second portion arranged on the terminal solar cell with the metal foil facing away from the terminal solar cell; and 
 a third portion connecting the first portion and the second portion, 
   the terminal solar cell of the first solar cell string, the terminal solar cell of the second solar cell string, and the terminal solar cell of the third solar cell string are arranged in the first direction,   the first wiring member electrically connects the second portion of the third wiring member of the second solar cell string and the second portion of the third wiring member of the third solar cell string, and   when viewed in a normal direction of a light-receiving surface of the solar cells, the extraction electrode does not overlap with the first wiring member, the second portion of the third wiring member of the second solar cell string and the second portion of the third wiring member of the third solar cell string.   
     
     
         6 . The solar module according to  claim 5 , further comprising
 an insulating sheet between the first wiring member and the solar cells.   
     
     
         7 . The solar module according to  claim 5 , wherein
 a length of the second portion of the third wiring member of the first solar cell string in the second direction is larger than a length of the second portion of the third wiring member of the second solar cell string in the second direction.   
     
     
         8 . The solar module according to  claim 6 , wherein
 the end portion of the terminal solar cell in the second direction is located on an outer side of the solar module than an end portion of the insulating sheet in the second direction.
