  However, in the proposals described in Patent Documents 1 to 5 and the like, the snow stopper prevents the snow from falling, but by preventing the snow from falling, the snow cover portion reduces the light receiving area of the solar cell, and as a result. There was a problem that led to a decrease in power generation. In addition, in the said patent document 1, although the transparent member was used in consideration of the light shielding of a snow stopper, it did not consider about the light shielding of the snow covered with a snow stopper.

  Therefore, an object of the present invention is to propose a snow stop structure using a solar cell that can guide the snow on the surface of the solar cell to the back space and can melt the snow smoothly in the back space.

  The present invention has been proposed in view of the above, and is a snow stop structure constructed by arranging a plurality of solar cells in the eaves direction, and laying solar cells on a lower layer material having rain performance. In addition, a space is formed between the lower layer material and the back surface of the solar cell, and the solar cells adjacent in the eaves ridge direction are disposed through openings at regular intervals, and the solar cell surface communicates with the back surface space through the opening. In the solar cells adjacent to the eaves building direction, a solar cell characterized in that an upright portion is provided on the lower side of the lower side end of the solar cell disposed on the side of the eaves is used. It relates to a snow stop structure.

  Further, the present invention provides a snow stop using a solar cell, wherein the upright portion is provided at a water upper end of the solar cell disposed on the eaves side in the snow stop structure using the solar cell. A structure is also proposed.

The snow stop structure using the solar cell of the present invention can drop the snow on the surface of the solar cell to the opening or from the opening to the back space, and smoothly the snow dropped in the opening or the back space. Can be melted.
That is, by providing openings at regular intervals between the solar cells in the eaves building direction, snow that slides on the solar cells can be dropped into the openings. Alternatively, it can be further dropped from the opening to the back space. Therefore, no snow dam is generated, and a decrease in efficiency due to the dam (which is shielded from light) is prevented. Moreover, since the back surface space of a solar cell becomes high temperature, the snow which fell to the opening part or the snow which fell to the back surface space can be melt | dissolved smoothly. Moreover, suppressing the temperature rise of the solar cell has the significance of preventing a decrease in power generation efficiency of the solar cell, so that snow that is originally discarded can be used efficiently. At that time, the upright portion serves to surely drop the snow that has slid down from the building side into the opening, and also releases the warmed air in the back space from the opening to the surface side of the solar cell, thereby melting the snow. In addition, the back space can be maintained at an appropriate temperature, and the snow on the front side can be easily slid.

  Further, when the upright portion is provided at the water upper end of the solar cell disposed on the eaves side, the width of the opening for guiding snow is most effectively used.

Solar cells may be directly attached to the members constituting these lower layer materials, or solar cells may be attached via attachments such as various mounting brackets, mounting brackets, carry-out brackets, horizontal rails, and vertical rails. May be. That is, the lower layer material in the present invention includes a lower roof or a mounting material attached thereto.

  In the first embodiment of the present invention shown in FIGS. 1 (a), (b) and (c), snow is constructed by arranging a plurality of solar cells 1 on a folded plate roof which is a lower layer material having rain performance. It is a stop structure, a space 11 is formed between the lower layer material and the back surface of the solar cell 1, and the solar cells 1 and 1 adjacent to each other in the eave building direction are disposed through the openings 2 at regular intervals. The solar cell 1 surface and the back surface space 11 communicate with each other, and among the solar cells 1 and 1 adjacent in the eave building direction, the lower side end of the solar cell 1 disposed on the building side is located on the lower side. In this configuration, the upright portion 3 is provided.

The sliding direction of snow (S) in FIGS. 1 (a) and 1 (b) is from top to bottom as indicated by arrows in the drawings, and the flow direction of wind (W) is indicated by white arrows in the drawings. As shown, it is from bottom to top, and the roles of the opening 2 and the upright portion 3 for these are shown in FIG.
In FIG. 2A, snow slides from the right side to the left side, that is, the right side is a ridge and the left side is an eave.
As shown in the figure, the snow (S) slides from the right side to the left side, and a part of the snow (S) collides with the upright part 3 as indicated by the dotted line, and then falls from the opening 2 to the back space 11.
In FIG.2 (b), when the wind blows from the left to the right side, ie, the blowing wind to a roof is assumed, the left side is an eave and the right side points to a building.
As shown in the figure, when the wind (W) blows from the left to the right, the wind hitting the upright portion 3 causes upward turbulence as indicated by the dotted line, and the upper end of the opening 2 is in a reduced pressure state. Therefore, the air in the back space 11 is sucked out to the front surface side.
2A and 2B, the right side indicates the ridge and the left side indicates the eaves. Snow (S) is guided from the opening 2 to the back space 11, and the air in the back surface 11 is discharged from the front surface 10. It became clear that

Moreover, since the back surface space 11 of the solar cell 1 becomes high temperature, the snow which fell to the back surface space 11 can be melt | dissolved smoothly.
Further, the upright portion 2 not only performs the function of guiding snow to the back space 11, but also releases the warmed air in the back space 11 to the front surface 10 side of the solar cell 1, thereby reducing the back space 11 appropriately. The temperature can be maintained, and it also serves to make the snow on the surface 10 side easy to slide down.
Moreover, in this 1st Example, since the standing-up-like part 3 was provided in the water side upper end of the solar cell 1 arrange | positioned at the eaves side, the width | variety of the opening part 2 for guiding snow is most effectively utilized. The

  The folded plate roof as the lower layer material to which the solar cell 1 in FIG. 1 is attached is a lower layer material having rain performance, and the lower holding member 5B and the upper holding member 5C, which are tight frames, are fixed on the housing 5A.
