More particularly, the present invention relates to a unit structure for supporting a solar cell module generating electricity using solar light in an inclined state, and an assembly including the unit structure.

Recently, the depletion of fossil fuels, the generation of carbon dioxide due to their use, and the climate change caused by them have become serious social problems, and new energy sources to replace fossil fuels are being developed worldwide. The most promising of these alternative energies is solar energy, which is continuously supplied and does not cause air pollution as long as the sun and the earth are present.

Power generation using the solar energy is performed using a solar cell module made of GaAs, monocrystalline silicon, polycrystalline silicon or the like, which is a compound semiconductor that can expect a photoelectric effect.

However, the power generation using such a photovoltaic module is not only higher in energy production cost than thermal power, hydroelectric power, and nuclear power, but also has a spectrum range of 250 to 1100 nm, which accounts for about 60% ultraviolet rays (UV) and visible light are used, the power generation efficiency is low.

Accordingly, in a country located at a latitude of 38 degrees, such as South Korea, in order to maximize the power production efficiency, the solar cell module is installed so as to be inclined by using a separate support structure so as to be exposed almost perpendicularly to the sunlight .

At this time, the support structure may have a structure in which a plurality of unit bodies are assembled together so that the solar cell module can be installed in various places in any place. Here, the unit body has been generally formed in the form of a square block so as to be rigid and easy to assemble, without a gap therebetween.

In this case, when an impact is applied to the supporting structure in which the rectangular unit-shaped unit bodies are assembled, or when expansion and contraction occur due to external temperature changes, the stress generated therefrom is concentrated in the unit bodies There is a concern that the unit bodies may be damaged.
