Solar cell module and manufacturing method therefor
View Patent ↗The present invention provides a solar cell module which keeps backing film from being scratched and prevents the occurrence of scratches. The solar cell module ( 10 ) of the present invention is provided with a surface protecting member ( 12 ), backing film ( 13 ), a plurality of solar cells ( 11 ) arranged between the surface protecting member ( 12 ) and the backing film ( 13 ) and electrically connected by means of wiring members ( 16 ), a filler material ( 14 ) for sealing the solar cells ( 11 ) between the surface protecting member ( 12 ) and the backing film ( 13 ), and transition wiring ( 20 ) electrically connected with the wiring members ( 16 ). Here, at least the end portion of transition wiring ( 20 ) positioned in a corner portion of the solar cell module is arranged so as to be positioned closer to the surface protecting member ( 12 ) than other portions of the transition wiring ( 20 ).
1. A solar cell module comprising:
a surface protecting member,
backing film, and
a plurality of solar cell strings arranged between the surface protecting member and the backing film, and electrically connected by transition wiring; wherein
each of the solar cell strings comprises: solar cells and a wiring member electrically connecting the solar cells,
each transition wiring includes a soldering connection area where the transition wiring is connected to the wiring member with solder,
an end portion, outside of the soldering connection area, of transition wiring positioned in a corner portion of the solar cell module is positioned closer to the surface protecting member than other portions of the transition wiring,
the end portion, outside of the solder connection area, of the transition wiring positioned in the corner portion of the solar cell module being positioned closer to the surface protecting member than other portions of the transition wiring is not in contact with and does not penetrate through the surface protecting member.
2. The solar cell module according to claim 1 , wherein the transition wiring is bent towards the surface protecting member so as to position the end portion of the transition wiring closer to the surface protecting member side than the other portions of the transition wiring.
