[Problems to be solved by the invention]
However, in a private house or a building-type building, there are many roofs that do not have a predetermined inclination like the above-mentioned roof 200, for example, a flat roof building. When arranging a solar power generation module in such a flat roof building, it is necessary to construct a structural support on the roof of the flat roof building and securely support the solar power module with the structural support. is there.
[0008]
As described above, it is necessary to mount the solar power generation module at an angle on the roof of the flat roof building in order to efficiently expose sunlight. For this reason, when installing a large-scale solar power generation module having an area necessary for obtaining the predetermined power, since the height from the installation surface increases, wind and rain hit the solar power generation module is extremely strong. Become.
[0009]
For this reason, it is necessary to make the above-mentioned structural support robustly, and it is very difficult to install a large solar power generation module on the roof or flat land of a flat roof building. When installing a module, the problem is that the cost is increased by the construction of the structural support, and if the wind and rain cannot be prevented, the inclination angle must be loosened with the knowledge that the power generation efficiency will decrease was there.
[0010]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is an object of the present invention to allow a solar power generation module to be installed in a state where the height of the solar power generation module from the mounting surface is suppressed. .
[0011]
[Means for Solving the Problems]
The solar power generation module of the present invention is a solar power generation module configured by solar cells for receiving sunlight and generating power, and a plurality of the solar cells are connected to form an elongated solar cell module. In addition, a predetermined number of the elongated solar cell modules are arranged on the fixing member at a predetermined angle.
Another feature of the present invention is that the solar cell module is disposed on the fixing member at an angle of 30 degrees.

[0012]
Since the present invention comprises the above technical means, the area receiving wind and rain can be distributed to a plurality of solar cell modules, and an area for receiving sunlight in a state where the solar power generation module is installed without any inclination can be secured. This makes it possible to simplify the structure of the structural support and improve the power generation efficiency.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of a solar power generation module of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a perspective view showing an embodiment of a solar power generation system according to the present invention. As shown in FIG. 1, the solar power generation system according to the present embodiment is configured by arranging a plurality of solar power generation modules 1 on a rooftop 2 of a flat roof building. In the example of FIG. 1, a total of 24 solar power generation modules 1 are arranged in four rows and six stages to constitute a solar power generation system. As described later with reference to FIG. 4, the solar power generation module 1 includes four solar cell modules 3 arranged side by side.
[0014]
As shown in FIG. 2, each of the solar cell modules 3 is configured by arranging a plurality of solar cells 13 a to 13 g to be elongated. In the present embodiment, seven solar cells 13 a to 13 g are arranged to form one. 1 shows an example in which three elongated solar cell modules 3 are configured. Each of the solar cells 13a to 13g has a size of, for example, about 153 mm × 150 mm.
[0015]
Then, as shown in FIG. 3, each solar cell module 3 is fixedly supported at a predetermined angle X by a structural support 4. In the present embodiment, the first support 4a, the second support 4b, and the third support 4c constitute the structural support 4 described above. The angle X for supporting the solar cell module 3 is set to 30 degrees.
[0016]
The solar cell module 3 supported by the structural support 4 is arranged in four rows (a plurality of rows) as shown in FIG. Then, as shown in FIGS. 4 and 5, both ends of the four rows (plural rows) of the solar cell modules 3 a to 3 d, 3 f to 3 i are fixed to one end of the flat roof building by one fixing member 5 and the other fixing member 6. It is fixed to the roof 2.
[0017]
The DC power generated by the plurality of solar power generation modules 1 is sent to a power conditioner through a connection box (not shown), and is converted into AC power used at home in the power conditioner.
[0018]
Further, in the present embodiment, a gap 30 is provided between the front and rear solar cell modules 3 so that dust, snow and the like dropped on the solar cell module 3 fall downward through the gap 30. I have. Thus, even when the solar power generation module 1 is configured by arranging the plurality of solar cell modules 3 in parallel, dust, snow, and the like are accumulated between the respective solar cell modules 3 and the solar cell modules 3. Good prevention can be achieved, and maintenance can be facilitated.
[0019]
Since the solar power generation module 1 of the present embodiment is configured as described above, an area required for receiving sunlight can be easily secured on the rooftop 2 of the flat roof building. Moreover, since the area receiving the wind and rain can be dispersed and the roof on the roof 2 of the flat roof building can be secured without any inclination, the structure of the structural support 4 can be simplified and sufficient power generation efficiency can be obtained. Can be obtained.
[0020]
Next, a modified example of the solar power generation module 1 of the present invention will be described with reference to FIG.
The above-described example shows an example in which the solar power generation module 1 of the present invention is mounted on the roof 2 or flat ground of a flat roof building, but the example shown in FIG. 6 shows an example in which the solar power generation module 1 is mounted on the wall surface 7 of the building. Is shown.
[0021]
When mounting the solar power generation module 1 on the wall surface 7 of a building, mounting at an inclination of about 30 ° with respect to the horizontal plane is the mounting method that maximizes the power generation efficiency. However, since one side of the module is about 1 m, However, when snow is accumulated on the module, the resistance to wind and rain, and the strength of the mounting become problems, the power generation efficiency is significantly reduced by mounting the module at an inclination angle of, for example, about 60 ° with respect to the horizontal plane.
[0022]
On the other hand, in the present embodiment, as shown in FIG. 6, each solar cell module 3 is provided with an inclination of about 30 ° with respect to the horizontal plane to form one solar power generation module 1 in a plurality of rows. Things. As described above, since the cells constituting each solar cell module 3 are approximately 15 cm, the effect of snow and wind and rain on each solar cell module 3 and the strength of the wall in mounting the solar cell module 3 are lower than before. No problem, so installation is simple.
[0023]
Since each solar cell module 3 has an inclination of about 30 ° with respect to the horizontal plane, the power generation efficiency as the solar power generation module 1 can be sufficiently obtained by keeping the distance between the solar cell modules 3 constant. Was.
[0024]
【The invention's effect】
As described above, according to the present invention, an elongated solar cell module is formed by arranging a plurality of solar cells, which are minimum units for receiving and generating sunlight, and Since a predetermined number of battery modules are arranged on the fixed member at a predetermined angle on the fixing member, the solar power generation module is configured, so that the area receiving the wind and rain can be dispersed in each solar cell module, and the solar power generation module is installed. It is possible to secure an area required for receiving sunlight in a state where there is no inclination on the surface, and it is possible to simplify the configuration of the structural support and increase power generation efficiency.
Further, according to another feature of the present invention, since a gap is provided between the plurality of solar cell modules, it is possible to prevent dust, snow, and the like from being deposited on each of the solar cell modules, and to reduce maintenance. In addition to being easy, durability can be improved.
