Description

[0001] The present invention relates to a photovoltaic power generation device,

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 manually adjusting an inclination angle of a solar cell module according to a change in altitude of the sun.

Recently, construction of eco-friendly power generation facilities using solar energy, wind power, and tidal energy, which are clean energy sources that do not cause environmental pollution problems, are gradually increasing, replacing fossil fuels.

Among these power generation facilities, a photovoltaic power generation apparatus that generates electricity by installing a plurality of solar cells that convert sunlight into electric energy is capable of generating electricity that can generate enough power to generate daily hot water for one household. It is being installed on a large scale to further increase.

The solar power generation apparatus has a problem that the efficiency of utilization of the sunlight can not be improved in the case of the conventional stationary photovoltaic power generation apparatus because the power generation amount is dependent on the solar radiation time and the incidence angle of the sunlight to the solar battery module.

In order to solve these problems, many tracking solar photovoltaic devices have been proposed that track the position of the sun using the power so that the direct sunlight of the sun can vertically enter the front surface of the solar photovoltaic module. Such power systems are disclosed in Korean Utility Model Registration No. 20-297771, Registration No. 10-044021, Registration No. 10-0483291, Registration No. 10-0369897, and the like.

However, in the case of such a power system, since some power is generated by the power required to operate the driving facility, the increase in the power generation amount that is increased compared with the fixed type by tracking the sunlight is less than the consumed power amount required for operating the driving facility The actual power generation efficiency may not be improved.

In addition, the structure becomes complicated by the addition of the drive facility, and the maintenance cost due to the economic burden and maintenance resulting therefrom can not be ignored.

In order to solve the above problem, a photovoltaic power generation apparatus configured to manually adjust the tilt angle has been proposed in Korean Patent No. 10-0760043. However, in the above photovoltaic apparatus, when the inclination angle is adjusted, the solar panel is backed by its own weight or wind in the process of disassembling the bolt and nut fixing the solar panel to be positioned at a certain angle, There is a risk of accident or twisting and safety accidents.
