Description

  The present invention relates to a photovoltaic power generation system.

  As shown in FIG. 9, the solar cell is generally installed on a dedicated mount 110 fixed to a rooftop, a wall surface, or the like via a rail or a frame 111 (for example, Patent Document 1).

JP 2003-20766 A

However, the conventional method for installing a solar cell has a problem in that it takes a lot of time to install the dedicated mount 110, the rails 111, etc., and the cost of materials is increased.
In addition, when solar cells are laid on the rooftop of a building having a rooftop ridge or the like, it is necessary to process a dedicated frame or the like according to the convex shape of the rooftop ridge roof, which requires labor.

  The present invention aims to solve the above-mentioned problems, and is not limited to the shape of the installation location, and provides a photovoltaic power generation system that can be installed simply and inexpensively. Let it be an issue.

In order to solve the above problems, the photovoltaic power generation system of the present invention has a fixing net fixed at a predetermined position with a gap on the back surface, a solar cell module installed on the surface of the fixing net, The solar cell module is arranged such that a vent hole is formed in an outer peripheral portion of the fixing net, and the fixing net combines wires in a lattice shape. The wire has a two-piece structure of a first thread that locks the solar cell module and a second thread that maintains the shape of the fixing net and is fixed to the building. A battery module is fixed to the first thread .

  In such a solar power generation system, the fixing net can be deformed according to the shape of the installation location, and therefore can be easily installed at a desired position regardless of the shape of the installation location.

Moreover, since the number of members is small, it is inexpensive.
Moreover, since the back surface is provided with a gap so that ventilation is possible, the wind pressure acting on the solar cell module is reduced.

Furthermore , since the fixing net is not deformed by fixing the solar cell module, the fixing degree is prevented from being lowered.

In the solar power generation system, a plurality of the solar cell modules may be arranged at intervals.
By arranging the solar cell module in this way, a ventilation path is formed around the solar cell module, so that the wind pressure exceeding the wind resistance standard is prevented from acting on the solar cell module.

  According to the photovoltaic power generation system of the present invention, it is possible to easily and inexpensively install without being limited to the shape of the installation location.

Preferred embodiments of the present invention will be described with reference to the drawings.
This embodiment demonstrates the solar power generation system 1 installed in the roof of the building 2 which has a rooftop ridge.

  As shown in FIG. 1, the solar power generation system 1 includes a fixing net 10 and a solar cell array 20 provided on the surface of the fixing net 10.

The solar power generation system 1 is installed with a gap S between the back surface and the building 2 as shown in FIG. In addition, as shown in FIG. 2B, the solar cell array 20 is arranged in the center portion of the fixing net 10, so that the vent holes Sa leading to the gap S are arranged around the solar cell array 20 (for fixing). The outer periphery of the net 10 is formed.
This facilitates ventilation of the front and back surfaces of the solar cell array 20 through the vent holes Sa during strong winds, and installs the solar cell array 20 while avoiding the outer peripheral portion of the roof surface where the wind pressure (negative pressure) is inherently large. As a result, the wind pressure acting on the solar cell array 20 can be reduced.

As shown in FIG. 2A, the fixing net 10 is fixed with a gap S between the surface of the building 2 and a fixing member 30.
In the present embodiment, as shown in FIG. 1, the fixing net 10 is fixed at least at the four corners of the fixing net 10 and the corners of the rooftop building. In addition, arrangement | positioning of the fixing member 30 is not limited, It can set suitably.

  The fixing member 30 includes a support column erected on the surface of the building 2, and the fixing net 10 is locked at the tip of the support column so that the fixing member 30 is interposed between the back surface of the fixing net 10 and the surface of the building 2. The fixing net 10 is fixed in a state having the gap S.

  In addition, the space | interval (height dimension of the fixing member 30) of the net 10 for fixing and the building 2 is set to the dimension which can reduce the wind pressure which acts on the solar cell array 20 by allowing a wind to pass through at the time of a strong wind. .

  The fixing net 10 is formed by combining metal wires (first thread 11 and second thread 12 shown in FIG. 3) in a lattice shape. In addition, the 1st thread | yarn 11 and the 2nd thread | yarn 12 which comprise a wire may be one steel wire (needles etc.), and may be a strand. Moreover, the wire which comprises the net | network 10 for fixation may be comprised with the super strong fiber, The material is not limited.

Further, as shown in FIG. 3A, the wire constituting the fixing net 10 includes a first thread 11 for locking the solar cell module 21 (solar cell array 20), and the shape of the fixing net 10. And a two-piece structure with a second thread 12 fixed to the building 2.
Note that the wire does not necessarily have a two-piece structure.

  The solar cell array 20 is configured by arranging a plurality of solar cell modules 21, 21,.

  The solar cell module 21 is an assembly of cells that convert light energy into electric power, and has a flat plate shape. The solar cell module 21 is accommodated in a box-type protective cover (not shown). In addition, the shape of the solar cell module 21 is not limited. Further, the number of solar cell modules 21 included in the solar power generation system 1 is not limited.

  As shown in FIG. 3, the solar cell modules 21 are arranged in a state of being spaced apart from each other. Thereby, a wind is passed between the solar cell modules 21, and the wind pressure which acts on the solar cell array 20 is reduced.

  As shown in FIG. 3C, the solar cell module 21 is fixed by locking a fixing bracket 22 fixed to the side surface of the solar cell module 21 to the first thread 11 of the fixing net 10.

  The fixing bracket 22 includes a module mounting portion 22a having a U-shaped cross-sectional view and a hook portion 22b formed at the bottom of the module mounting portion 22a.

The fixing bracket 22 is fixed to a side end portion of the solar cell module 21 by a module mounting portion 22a.
The hook portion 22b is formed in a letter shape, and locks the first thread 11 and prevents the first thread 11 from slipping out.

  The solar cell module 21 is fixed to the fixing net 10 by the tension of the first thread 11 by being locked to the first thread 11 via the fixing fitting 22.

  In the present embodiment, the fixing brackets 22 are installed at two locations (eight locations in total) with respect to each side of the solar cell module 21, but the number and arrangement of the fixing brackets 22 are not limited. .

  The electrical wiring connected to the solar cell module 21 is wired by being partially fixed along the yarn (second yarn 12) of the fixing net 10.

  As described above, according to the photovoltaic power generation system 1, the installation of the solar cell module is not performed by using a net (fixing net 10) that can freely change the shape, instead of using a frame, a rail, or the like. It became possible to improve the degree of freedom.

For this reason, it is possible to easily install even an installation location having a breakage point, such as a rooftop having a convex portion such as a rooftop building.
Therefore, it can be easily installed at an installation location where a large amount of sunlight can be received. In addition, since a stand for installing solar cells is not required, the material cost can be reduced.

A vent hole Sa is formed around the solar cell array 20, and a gap S is formed between the back surface of the solar power generation system 1 and the building 2. Wind pressure can be reduced.
Moreover, since the solar cell array 20 is formed by arranging the solar cell modules 21 at intervals, it is possible to further reduce the wind pressure by allowing the wind to pass between the solar cell modules 21. It becomes.
Therefore, even when a strong wind such as a typhoon is generated, it is possible to prevent the wind pressure higher than the typhoon pressure reference value of the solar cell module 21 from acting on the solar cell module 21 (solar cell array 20). .

At this time, the adjacent solar cell modules 21 are connected to each other via the fixing member 24 disposed across the adjacent frame members 23 and 23. The frame member 23 has an insertion hole 23a (see FIG. 4 (c)) or a notch 23b (FIG. 4 (FIG. 4) for inserting the wire (the first thread 11 or the second thread 12) of the fixing net 10. d)) is formed. The fixing member 24 may be fixed to the frame member 23 via a known jig such as a screw 24a. Further, the configuration of the fixing member 24 is not limited and can be set as appropriate.

  Moreover, as a fixing method of the solar cell module 21 when the wire material (wire) 11 ′ of the fixing net 10 is one, the solar cell module 21 is connected to the wire material 11 ′ via a fixing member 25 as shown in FIG. What is necessary is just to fix to. For example, as shown in FIGS. 5B and 5C, a frame installed around the solar cell module 21 on the fixing member 25 in a state where the wire 11 ′ is gripped in the wire fixing portion 25 b of the fixing member 25. The member 23 is fixed. The fixing method of the frame member 23 and the fixing member 25 is not limited, but may be appropriately performed, for example, by screwing with a screw 25a. The configuration of the fixing member 25 is not limited and can be set as appropriate.
