Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for installing a solar cell module on a rooftop, and more particularly, to a structure for installing a solar cell module in combination with a heat insulating block laid on a rooftop.
[0002]
[Prior art]
When installing a solar cell module on the roof of a flat roof with a flat roof, such as the roof of a building, if the building is a new building, special foundation materials and Generally, fixed support means is provided (for example, see Non-Patent Document 1). On the other hand, in the case of existing buildings including new construction where solar cell module installation was not considered initially, new roof tops were remodeled to install solar cell modules and additional dedicated foundations were installed, Alternatively, a large-scale steel base must be installed.
[0003]
That is, when a solar cell module is installed in a newly-built building, the construction of the installation foundation prolongs the construction period of the building, and eventually increases the installation cost of the solar cell module. Similarly, in the case of installing a solar cell module in an existing building, additional construction of a rooftop and installation of a large-scale steel gantry increase the installation cost of the solar cell. In particular, when the installation foundation is additionally installed on the roof of an existing building, it is necessary to pay close attention not to impair the waterproof function of the roof surface.
[0004]
On the other hand, in a region where the solar radiation is strong, it is common practice to lay a plurality of heat insulating blocks on a flat roof having a flat roof such as a building roof to mitigate a rise in temperature inside the building due to the solar radiation. This heat-insulating block has a flat or square shape and is used by being laid like a tile on a flat roof. Conventionally, an integrated solar cell module in which a solar cell is directly incorporated into the heat-insulating block has been proposed (for example, And Patent Document 1.).
[0005]
However, since the small solar cells integrally attached to each heat insulating block are gathered together, the area efficiency of the light receiving surface is low and the power generation capacity is limited, and the heat insulating effect of the solar cell module is generally a single heat insulating block. It was considerable, and the effect of further improving the heat insulating property by incorporating the solar cell could not be expected.
[0006]
Further, since the light receiving surface of each solar cell is substantially horizontal, there is a problem that rainwater easily accumulates on the surface and the surface is easily soiled. In addition, a system will be constructed by connecting a large number of solar cells for each heat insulation block, but the wiring cost between modules, especially the number of expensive connectors that require reliability and waterproofness, will increase, and the time and effort for implementation will increase. This was the cause of the cost increase. Furthermore, these wirings need to be housed under the heat insulating block, and there is a problem that the wiring work is extremely troublesome.

If the height is higher than 200 cm, it will be necessary to strengthen the base in the seismic design and work at a high place during installation work, which will require special safety equipment, which will increase the cost, and in some cases, modify the lightning rod It is necessary to add more.

It is preferable that the mounting structure is a heat insulating block located at the intersection of the base frame and the mounting frame, and the upper and lower frames are connected by the fixing means.
[0012]

Further, when the roof surface on which the heat insulating block is laid has irregularities, a clogging material is installed at a lower portion of the heat insulating block installed on the concave portion so that the upper surfaces of the plurality of heat insulating blocks are substantially flat. Is preferred.
[0016]
Further, an installation structure provided with a connecting means for connecting a predetermined heat insulating block to which the gantry is fixed and another heat insulating block disposed adjacent to the predetermined heat insulating block is preferable.
