Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a solar cell module frame for mounting a solar cell module on a roof or the like. In particular, the present invention relates to a solar cell module frame suitable for mounting a solar cell module on a substantially horizontal roof such as a folded roof or a flat roof.

[0002]

2. Description of the Related Art In recent years, as the problem of global environment and energy depletion due to increased consumption of fuel such as coal and petroleum has become more serious, a solar cell mount as disclosed in Japanese Patent Application Laid-Open No. 8-274364 has been developed. On the roof of a house, etc.
Attention has been paid to a solar power generation device on a roof that supplies clean and infinite solar energy into electric power and supplies it to a house by using the solar cell panel.

[0003] The solar cell stand described in Japanese Patent Application Laid-Open No. 8-274364 includes a solar cell panel, a plurality of legs for fixing the solar cell panel by being inclined at a predetermined angle, and a space between adjacent legs. And a protection plate provided on the substrate. Here, the solar cell panel is a panel formed by connecting a plurality of solar cell modules.

[0004]

However, a solar cell panel in which a plurality of solar cell modules are connected is a plate-shaped body having a large area. The wind hits strongly. Therefore, in order to prevent the solar cell panel from being blown away by the wind, a sturdy leg or a protective plate is required, which is expensive.
Further, when the leg portions and the protection plate are made strong, the weight increases.
For this reason, the mounting work for mounting the solar cell gantry requires assembling a heavy solar cell gantry at a high place called a roof, and this mounting work is difficult and requires a large number of mounting steps.

[0005] Further, since a large load is applied to the legs supporting the heavy solar cell panel, when the legs are installed on a slate tile or a metal sheet roof material such as a folded roof,
A concentrated load is applied to the roofing material under the leg, and the roofing material is easily damaged. Therefore, in order to prevent the roofing material from being damaged, it is necessary to attach a wide support plate for widely dispersing the load on the legs, which is further expensive.

Accordingly, an object of the present invention is to provide a solar cell module frame in which a solar power generation device can be easily mounted on a roof.
