[0001] Solar power generation device [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solar power generation device, and more particularly, to a solar power generation device capable of adjusting the inclination angle and height of a solar cell module so that sunlight can be optimally incident on the solar power generation device.

Recently, the construction of eco-friendly power generation facilities using solar energy, wind power, and tidal power, which are clean energy that does not cause environmental pollution problem, is gradually increasing.

Among these power generation facilities, a photovoltaic power generation apparatus that generates a large number of solar cells by converting solar energy into electric energy is installed on a large scale so that the power generation amount can be further increased in a small scale capable of generating daily power consumption of one household .

Generally, photovoltaic power generation is a power generation device that installs a solar cell module on a supporting structure by installing a supporting structure on a ground, or installs a solar cell module on the outer wall of a building. While such solar power generation has an advantage of being environmentally friendly, it is required to have a large installation space that can cope with the size of a solar cell panel to be applied. Therefore, it is mainly installed in an unused space or in an area where economical efficiency is relatively low.

However, since most of the solar cells are arranged in parallel in one direction and occupy a lot of space, partial settlement may occur over time. In particular, solar power generation is often installed in soft grounds such as river sites, reservoirs, and reservoirs that are inefficiently used and economically inefficient for economical facilities. Therefore, solar power generation efficiency due to partial subsidence often arises.

In the case of subsidence of the ground installed with photovoltaic power generation, the deformation force acts on the supporting frame due to the varying depth of the supporting structures of the photovoltaic power generation. As a result, due to deformation of the structure, The degree may vary. In addition, cracks may occur in the solar module due to the deformation of the structure, which may result in deterioration of the photovoltaic power generation efficiency.

Korean Patent Laid-Open No. 10-0840400 discloses a tilt-angle-controlled solar power generation system in which the inclination angle of the solar panel can be manually adjusted according to the altitude of the sun, but there is no structure capable of adjusting height and position to be.
