Abstract

First and second engaging members (15) each including an engaging portion (15n) are attached to a ridge-side end of each of first through third solar cell panels (11) and are disposed with an interval in a beam direction. First and second engaged members (21) each including an engaged portion (21i) are attached to an eaves-side end of each solar cell panel (11) and are disposed with an interval in the beam direction. The engaging portion (15n) of the first engaging member (15) of the first solar cell panel (11) is engaged with the engaged portion (21i) of the first engaged member (21) of the second solar cell panel (11), whereas the engaging portion (15n) of the second engaging member (15) of the first solar cell panel (11) is engaged with the engaged portion (21i) of the second engaged member (21) of the third solar cell panel (11).

First claim

The invention claimed is:

1. An installation structure of solar cell panels, the installation structure including first through third solar cell panels disposed on a roof surface such that the first solar cell panel is adjacent to an eaves side of each of the second and third solar cell panels, wherein
first and second engaging members each including an engaging portion are attached to a ridge-side end of each of the solar cell panels, the first and second engaging members being disposed with an interval in a beam direction,
first and second engaged members each including an engaged portion are attached to an eaves-side end of each of the solar cell panels, the first and second engaged members being disposed with an interval in a beam direction, and
the engaging portion of the first engaging member of the first solar cell panel is engaged with the engaged portion of the first engaged member of the second solar cell panel, whereas the engaging portion of the second engaging member of the first solar cell panel is engaged with the engaged portion of the second engaged member of the third solar cell panel.

2. The installation structure of solar cell panels according to claim 1 , wherein
relative positions, in the beam direction, of the engaging portion of the first engaging member and the engaged portion of the second engaged member relative to each of the solar cell panels are identical, and relative positions, in the beam direction, of the engaging portion of the second engaging member and the engaged portion of the first engaged member relative to each of the solar cell panels are identical.

3. The installation structure of solar cell panels according to claim 1 , wherein
one of the engaging portions of the first and second engaging members or the engaged portions of the first and second engaged members are grooves extending in the beam direction, and
another of the engaging portions of the first and second engaging members or the engaged portions of the first and second engaged members are projecting strips inserted in the grooves.

4. The installation structure of solar cell panels according to claim 3 , wherein
the engaging portions of the first and second engaging members are grooves extending in the beam direction and open to a ridge side, and are located at a front side of the ridge-side end of the solar cell panel to which the first and second engaging members are attached, and
the engaged portions of the first and second engaged members are projecting strips extending in the beam direction and projecting to the eaves side, and are located at a back side of the eaves-side end of the solar cell panel to which the first and second engaged members are attached.

5. The installation structure of solar cell panels according to claim 1 , wherein
ridge-side holding members holding the ridge-side end of each of the solar cell panel at both sides in a thickness direction are attached to the ridge-side end of the solar cell panel, and are disposed with an interval in the beam direction, and
each of the first and second engaging members includes a ridge-side contact face in contact with the ridge-side holding member at the back side of the solar cell panel, and a ridge-side projection projecting to the front side of the solar cell panel relative to the ridge-side contact face at both outer sides of the ridge-side contact face in the beam direction and facing both outer sides of the ridge-side holding member in the beam direction.

6. The installation structure of solar cell panels according to claim 1 , wherein
eaves-side holding members holding the eaves-side end of each of the solar cell panel at both sides in a thickness direction are attached to the eaves-side end of the solar cell panel, and are disposed with an interval in the beam direction, and
each of the first and second engaged members includes an eaves-side contact face in contact with the eaves-side holding member at the back side of the solar cell panel, and an eaves-side projection projecting to the front side of the solar cell panel relative to the eaves-side contact face at both outer sides of the eaves-side contact face in the beam direction and facing both outer sides of the eaves-side holding member in the beam direction.

7. The installation structure of solar cell panels according to claim 1 , wherein
each of the first and second engaging members is formed of a metal,
a first connection portion is provided in at least one of the first and second engaging members attached to the first solar cell panel,
a second connection portion is provided in at least one of the first and second engaging members attached to the second solar cell panel, and
the first and second connection portions are connected to each other through a ground wire to thereby electrically connect the first and second solar cell panels to each other.
