Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar cell module, and more particularly to a solar cell module suitable for being installed on the roof of a building such as a house where fire resistance is required, and a roof of the solar cell module. Regarding the installation method of.

[0002]

2. Description of the Related Art In recent years, a panel-shaped solar cell module has been installed on a roof of a house or the like to protect a clean solar environment due to serious problems of global environment and energy depletion caused by increased consumption of fossil fuels. Attention has been paid to a solar power generation system for homes that directly extracts electric power from energy and supplies it to homes. This type of solar cell module is a panel-shaped assembly of a large number of minimum-unit solar cells called cells. The solar cells are roughly classified into silicon solar cells, compound semiconductor solar cells, and organic semiconductor solar cells. Etc. Among these three types of solar cells, the organic semiconductor solar cell currently has a conversion efficiency from sunlight to electric energy of 1% or less, and has a long way to practical use. The production cost is high, and it is only slightly produced for special purposes. In other words, silicon solar cells account for most of the total solar cell production. Silicon solar cells include single crystal silicon solar cells,
There are polycrystalline silicon solar cells, amorphous silicon solar cells, and the like. Each of these three types of silicon solar cells has its own characteristics, but the one with the highest conversion efficiency is the single crystal silicon solar cell, and then the polycrystalline silicon solar cell. For this reason, crystalline (single crystal / polycrystal) silicon solar cells are generally used for electric power for homes.

However, these crystalline silicon solar cells cannot be directly formed on the back surface of a glass substrate as a supporting plate like amorphous silicon solar cells and compound semiconductor solar cells (for example, Japanese Patent Laid-Open No. 5-29).
9686), conventionally, as shown in FIG. 14, a large number of crystalline silicon solar cells 1, 1, ... And EVA (ethylene vinyl acetate) 2 which is a filling adhesive.
Between the glass substrate 3 and the back cover case 4, and
A2, the glass substrate 3, and the back cover case 4 are thermocompression bonded to form a laminated structure, so that the crystalline silicon solar cells 1, 1, ... Are enclosed by the EVA 2, the glass substrate 3, and the back cover case 4. A solar cell module was manufactured by fitting a metal frame 5 made of aluminum or the like into the peripheral portion of the laminated body in order to provide moisture resistance and high insulation properties, and also to provide strength of the entire module (ibid.). reference).

[0004]

By the way, the above EVA
No. 2 has excellent moisture resistance and little deterioration of light transmission due to ultraviolet rays, so it can be said that it has essential qualities as a filling adhesive (encapsulant) for solar cell modules, but unfortunately it is very difficult. It had the drawback of being easily burned. Therefore, arranging a large number of the above-mentioned conventional solar cell modules side by side on the roof is equivalent to arranging a large amount of combustible materials on the roof, and therefore the solar cell modules are arranged on the roof where the fireproof structure is not adopted. It is installed for disaster prevention,
It was pointed out that it was not preferable. Further, conventionally, in order to install a solar cell module on the roof surface after roofing,
Since a dedicated stand was required, the overall cost of the solar power generation system was high.

The present invention has been made in view of the above circumstances, and by having a function as a roofing material having fireproof performance, it is possible to omit a dedicated mount and a roofing material, and to mount a crystalline silicon solar battery cell. It is an object of the present invention to provide a solar cell module and a method for mounting the solar cell module on a roof.

A plurality of the solar cell modules in the front stage are arranged side by side in a direction orthogonal to the flow direction of the roof flow surface, and a fixture is inserted into each of the mounting fixture insertion holes of the solar cell modules in the front stage. , After fixing these solar cell modules of the preceding stage to the roof base material or roof tiles with the inserted fixtures, a plurality of the solar cell modules or slate tiles of the subsequent stage are placed in a direction orthogonal to the flow direction of the roof flow surface. And, the downstream side portion of the hollow storage portion or the slate roof tile of the solar cell module of the latter stage, the plurality of the solar cell module of the previous stage, the preceding solar cell module corresponding to the solar cell module and the adjacent solar The battery modules are sequentially arranged in a manner to straddle the above-mentioned mounting portion of the battery module, and the mounting fixture insertion holes or slate roof tiles of the solar cell modules at the latter stage are arranged. The fixing fixture is inserted through the mounting fixture insertion hole, and the solar cell module or the plurality of solar cell modules is fixed by the procedure of fixing the solar cell module or the slate roof tile at the latter stage to the roof base material or the tile rail with the inserted fixture. The method for mounting a solar cell module on a roof according to claim 4, wherein the solar cell module and the slate are mounted and fixed on the roof flow surface.
