2. Description of the Related Art Most of the solar cell modules that make up a solar power generation system employ a so-called superstrate structure. FIG. 11 is a perspective view of the disassembled state, and FIG. FIG. 13 is a partial sectional view thereof.

This super straight type solar cell module 50 includes a large number of solar cells 51a, 51a.
Are connected in series or in parallel by an interconnector or the like, and the solar cell array 51 is filled with a filling material 5 made of a transparent resin.
A rectangular plate-shaped solar cell assembly is formed so as to be sandwiched by a white tempered glass plate 53 forming a light receiving surface and a weather resistant film 54 on the back surface via 2, 52, and the peripheral edge of the solar cell assembly. The long side frame bodies 55, 55 and the short side frame bodies 56, 56, which are extruded products of aluminum or the like.
The elastic packing material 5 for cushioning and waterproofing
It has a structure in which the frame body 55 for long sides and the frame body 56 for short sides, which are adjacent to each other, are fitted and supported via 7 and are connected by a screw 58.

Further, fixing ribs 55a, 55a for fixing to a frame (not shown) are formed over the entire length of the long side frame bodies 55, 55, and these fixing ribs 55a, 55a,
There are provided screw insertion holes 59, 59 ... For fixing to the frame.

A terminal box 60 is attached to the back surface of the solar cell module 50, and an output cable 61 is led out from the terminal box 60.

A solar cell module 50 having such a structure
A grid-connected solar power generation system for homes, which is installed in a general house, is becoming widespread.

FIG. 14 shows a state in which such a grid-connected type photovoltaic power generation system for a house is installed in a general house.

This solar power generation system includes a frame 70 mounted on a roof and a plurality of solar cell modules 50.
Solar cells array A connected in series or in parallel and arranged in a flat plate, a connection box 71 into which direct current power generated in the solar cell array A is guided via a cable, and this connection box 71
An inverter 72 for converting DC power derived from the AC power into AC power, and an indoor distribution board 73 guided from the inverter 72 and connected to a commercial power system.

The generated power from each solar cell module 50 is supplied to the electric equipment in the home from the indoor distribution board 73, and the surplus power can be sent to the commercial power. Therefore, the measuring unit 74 equipped with two watt-hour meters measures the electric power input from the commercial power system and the electric power sent to the commercial power system, respectively.

The solar cell module 50 having such a configuration
As a general structure for attaching the roof to the roof, as shown in FIG. 15, a roofing material 8 that is roofed with roof tiles, slates, metal plates, etc.
5, a mount 70 made of a metal material such as steel or aluminum is installed on the mount 5, and the solar cell module 50 is mounted on the mount 70.
