Japanese Patent No. 3700646 JP 2009-299451 A JP 2006-278671 A

However, in the proposals described in Patent Documents 1 to 3 and the like, the snow stopper itself is provided with a fixing portion, and the fixing portion is fixed to a frame or the like. There was a risk that the load of the above would cause deformation of the frame or a decrease in strength.
In the above proposal, the snow stopper prevents the snow from falling, but by preventing the snow from falling, the snow-covered portion reduces the light receiving area of the solar cell, resulting in a decrease in power generation. There was also a problem.

  Therefore, the present invention can easily install the solar cell panel, and reduces the strength of the solar cell panel itself by using a protrusion such as a snow stopper that extends from the surface of the solar cell panel to the upper surface side. It aims at proposing the installation structure of the solar cell panel which can be attached easily, and its construction method.

The present invention has been proposed in view of the above, and the mounting material fixed to the base and the bottom surface of the water-side edge are placed on the mounting material, or the side vertical surface of the edge is aligned. A solar cell panel, and a presser material that presses the water upper end of the solar cell panel and is fixed to the mounting material, and extends to the upper surface side from the surface of the solar cell panel to the mounting material or the presser material and dams The present invention relates to an installation structure for a solar cell panel, characterized in that a protruding portion is provided that can drop the stopped snow into the back surface space from the arrangement interval between adjacent solar cell panels on the water side.

  The present invention also proposes a solar cell panel installation structure characterized in that, in the solar cell panel installation structure, the attachment member or pressing member provided with the protrusions is a continuous material.

The present invention also proposes a solar cell panel installation structure characterized in that in the solar cell panel installation structure, the lower end of the solar cell panel is held and held by a fixing member.

Furthermore, the present invention is a method for constructing the solar cell panel installation structure, and after the first step of fixing the mounting material to the base, the bottom surface of the water-side edge of the solar cell panel is attached to the mounting material. Or a step (hereinafter, referred to as a panel laying step) for fixing the side vertical surface of the edge, and a step (hereinafter referred to as a pressing material) for fixing a pressing material for pressing the water upper end of the solar cell panel to the mounting material. And a mounting method of the solar cell panel, characterized in that a projecting portion is provided on the mounting material or the pressing material and is extended from the surface of the solar cell panel to the upper surface side. It is what we propose.

In the solar cell panel installation structure of the present invention, since the projecting portion extending from the solar cell panel surface to the upper surface side is provided on the mounting material or the pressing material, for example, snow or snow slides acting on the projecting portion, Loads such as wind blowing can be borne on the ground. Therefore, the load acting on the snow stopper as in the conventional structure is never applied to the frame or the like constituting the solar cell panel to cause deformation or a decrease in strength. Moreover, since it can fix firmly, without being influenced by the shape, dimension, etc. of the flame | frame etc. which comprise a solar cell panel, it can apply with respect to various solar cell panels.
Further, the bottom surface of the water-side edge of the solar cell panel is placed or the side vertical surface of the edge is aligned and held by a pressing member, and the projecting portion extending upward is also a solar cell. Since the structure is provided at the water top of the panel, snow and rain water can be dropped from the water top end of the solar cell panel to the arrangement interval, and further into the back space, or flow down at the protrusion. Therefore, it is possible to prevent a decrease in efficiency due to the blocking (which is shielded from light).
Furthermore, since the projecting portion also serves to discharge air in the back surface space of the solar cell panel, heat exhaust in the back surface space of the solar cell panel can be smoothly performed, and a decrease in power generation efficiency of the solar cell is suppressed. be able to.
Moreover, the exhaust heat of the back space smoothly melts the snow dropped in the space between the solar cell panels or the back space, and conversely, the snow dropped in the back space contributes to the suppression of the temperature rise in the back space. Become.

  In addition, when the mounting material or presser material provided with the protrusion is a continuous material, the length of the protrusion can be formed continuously, so that the snow stop function and the like can be enhanced as necessary. Is also possible.

  Furthermore, in the construction method of the solar cell panel installation structure, either the panel laying step or the pressing member mounting step may be performed first after the first step of fixing the mounting material to the base. Since the solar cell panel is disposed after the attachment material is first attached, the solar cell panel can be disposed very easily, and can be disposed at an appropriate position without causing a shift in the opposite direction. it can.

The installation structure of the solar cell panel of the present invention is (A) the mounting material fixed to the base, and one side (for example, the water side) facing the mounting material is placed or installed (B). The mounting material or the pressing material, comprising: a solar cell panel and a pressing material (C) that is fixed to the mounting material by pressing one side of the solar cell panel (in this case, the water side). And a protruding portion extending from the surface of the solar cell panel to the upper surface side.
With this configuration, since the protruding portion that extends from the surface of the solar cell panel to the upper surface side is provided on the mounting material or the pressing material, it is necessary to load the ground with a load such as snow or snow sliding that acts on the protruding portion. Can do. Therefore, the load acting on the snow stopper as in the conventional structure does not act on the frame or the like constituting the solar cell panel and cause deformation or strength reduction. Moreover, since it can be firmly fixed without being influenced by the shape and dimensions of the frame and the like constituting the solar cell panel, it can be applied to a wide variety of solar cell panels and has high practical value. Hereinafter, the (A) mounting material, (B) solar cell panel, and (C) pressing material used in the present invention will be described.

(A) Attachment material The attachment material used in the present invention is attached to a base such as an existing roof or a base attached to the existing roof, and is composed of a piece material or a threading material (continuous material), and is an edge of the solar cell panel. Is arranged in a mounting shape or a side-by-side shape.

  Further, as described above, the base is a well-known roof such as an existing roof tile, slate, metal, etc. for laying a solar cell panel as described above, and is a gantry combined with steel materials attached to these existing roofs. Also good. The solar cell panel (B) to be described later is mounted on the base via a space (back surface space), and the back space communicates at least in the flow direction. Moreover, this back space also includes a lower part than the attachment location (underlay) to which the attachment material is attached.

(B) Solar cell panel The solar cell panel used in the present invention is formed into a substantially rectangular planar shape as described above, and two pairs of opposing edges are formed. ) Place or install the opposite edge of the mounting material on one side. The “opposite one side” refers to one side of the opposing sides in the state in which the solar cell panel is laid, and generally coincides with the laying direction of the panel. Even if it is considered to indicate the long side or the short side of the panel itself, there is no problem. In short, any edge of the solar cell panel may be used, but the edge on the side that is placed or installed on the (A) mounting material, and the edge that is pressed and held by the pressing material (C) described later, It shows that it is the same edge. Therefore, naturally, the arrangement direction of the solar cell panel is specified in advance before construction, and the shape of the mounting material and pressing material is also determined accordingly, so the edge can be arbitrarily changed during construction. is not. And the laying direction may be the flow direction or the carry direction of the foundation, or is not limited to these when laying in a substantially flat shape in which the flow direction (inclination) is not clear.
This solar cell panel may be a module obtained by laminating crystalline solar cells on glass or the like, or may be a thin film such as an amorphous material. It may be integrated with a metal plate or the like to be a sheet (plate) or a board.
Further, the solar cell panel may be constructed by laying the above-described module, sheet, board, or the like as it is, or by laying a frame (frame) around the periphery.
Furthermore, in order to increase the amount of power generation, a double-sided light reception (power generation) type solar cell may be used. In this case, a reflective portion may be interposed on the back side of the solar cell, and a solar cell that is also used as a base is provided separately. It may be a thing.
This solar panel is a product with a frame (frame) around the periphery of the solar cells and modules. As described above, the specifications for attaching a snow stopper to the frame are the strength of the frame. It is often not overlooked from the viewpoint of decline.

(C) Presser Material The presser material used in the present invention refers to a member that presses the opposite edge of the (B) solar cell panel, and is fixed to the (A) mounting material. For example, in the case where the mounting member is disposed along the water-side edge of the solar cell panel, the water-side edge of the solar cell panel is disposed and fixed so as to be pressed by the pressing material. . That is, (A) the edge of (B) the solar cell panel on the side placed or placed along the mounting material is fixed by this (C) pressing material. The fixing method may be a known fixing method such as direct fixing with a screw or the like, fastening with a bolt and nut, engagement or fitting. Further, the pressing material may be a piece material or a threading material (continuous material).

Furthermore, even if the protrusion used in the present invention is formed integrally with the (A) mounting member having the above-described configuration or the (C) pressing member having the above-described configuration, a separate member provided with the protrusion is used. It may be assembled (attached) to (A) the attachment material or (C) the pressing material. When attaching another member, the attachment method, direct fixing with a screw or the like, fastening with a bolt and nut, engagement, fitting, and the like are assumed. Further, the protrusion is preferably a continuous material, but is not necessarily limited to a continuous material as long as the snow stop and air discharge effects can be obtained.
In addition, as described above, the projecting portion is provided for the purpose of preventing snow and discharging air, so that, for example, the solar cell panel is arranged on a ground with a clear flow direction, that is, a ground with a gradient. However, when the solar cell panel is disposed on a substantially flat base, that is, a base with almost no gradient, the installation conditions (wind direction, etc.) are taken into consideration. Should be provided.

  In the present invention, the (A) mounting material is provided with (B) one side facing the solar cell panel, and (B) one side facing the solar cell panel is pressed with the (C) pressing material (= (B) The other side of the solar cell panel opposite to the other side is not particularly limited, but may be held by a fixing member or the like as shown in the illustrated embodiment described later.

And in this invention, since the protrusion part extended to the upper surface side from the (B) solar cell panel surface as mentioned above is a structure provided in (A) attachment material or (C) pressing material, it protrudes. For example, loads such as snow, snow fall, and wind blowing that act on the portion can be borne on the ground without acting on the frame or the like that constitutes the solar cell panel. Therefore, it does not cause deformation and strength reduction of the solar cell panel, and can be firmly fixed without being affected by the shape and dimensions of the frame constituting the solar cell panel, etc. Applicable.
Note that, as described above, the back surface space of the solar cell panel includes a portion below the attachment location (fixed portion) of the attachment material, and indicates a space between the solar cell panel and the base.

In particular a one side is water side facing, when the other side facing is Underwater side置又mounting water upper end of the solar cell panel to the mounting member (water under side) of the presser while沿設It becomes a structure to hold | maintain with a material, It becomes a structure where the protrusion part extended upwards is also provided in the water upper end of a solar cell panel. Therefore, snow and rain water can be dropped or flowed from the upper end side of the solar cell panel to the back surface space at the protruding portion, so that no snow dam is generated and light is blocked by the dam ( Efficiency) can also be prevented. Furthermore, since this protrusion part guide | induces the blown wind so that a turbulent flow may be caused upwards, it is possible to discharge | emit the air in the back surface space of a solar cell panel by the pressure_reduction | reduced_pressure by this turbulent flow, The exhaust heat in the back surface space of the battery panel can be smoothly performed, and a decrease in power generation efficiency of the solar battery cell can be suppressed.
