Abstract

A solar panel includes conductors each having a first base portion, which is connected to a third base portion with a first connecting portion, and a second base portion, which is connected to the third base portion with a second connecting portion. Output leads include a distal end portion and an extending portion. The distal end portion extends in a first direction along a second front surface of a back cover and is connected to the third base portion from the side opposite from a solar cell. The extending portion is continuous with the distal end portion and extends in a first direction toward the solar cell along a second back surface of the back cover. The first connecting portion and the second connecting portion are elastically deformable in the first direction and a second direction, which intersects the first direction.

Claims8

Dependent claims

A solar panel comprising:

a plastic protective cover having light transparency allowing light to pass through from a first front surface to a first back surface;
a plastic back cover;
a solar cell;
a conductor, which is arranged next to the solar cell in a first direction and is connected to the solar cell to permit electricity to flow therebetween;
a sealing member, which retains the solar cell and the conductor between the protective cover and the back cover in a sealed state;
and
a plurality of output leads configured to transmit electricity generated by the solar cell, wherein
the back cover includes a second front surface joined to the sealing member and a second back surface located on an opposite side to the second front surface,
the conductor includes
a first base portion, which is secured to at least one of the protective cover and the back cover, is arranged next to the solar cell in the first direction, and is connected to the solar cell,
a second base portion, which is located at a position away from the first base portion in a second direction, which intersects the first direction, is secured to at least one of the protective cover and the back cover, is arranged next to the solar cell in the first direction, and is connected to the solar cell,
a third base portion located between the first base portion and the second base portion,
a first connecting portion, which is located between the first base portion and the third base portion and connects the first base portion to the third base portion, and
a second connecting portion, which is located between the second base portion and the third base portion and connects the second base portion to the third base portion,
each output lead includes
a distal end portion, which extends in the first direction along the second front surface and is connected to the third base portion from a side opposite from the solar cell, and
an extending portion, which is continuous with the distal end portion and extends in the first direction toward the solar cell along the second back surface,
at least part of the extending portion is secured to the second back surface, and
each of the first connecting portion and the second connecting portion is elastically deformable in the first and second directions.
