Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a solar cell array,

The present invention relates to a supporting apparatus for a solar cell array, and more particularly, to a supporting apparatus for a solar cell array, and more particularly, to a solar cell array supporting apparatus for a solar cell array, The present invention relates to a supporting device for adjusting the inclination angle of a solar cell array so as to stably obtain power generation efficiency.

The need to use alternative energy is becoming increasingly recognized as concerns about environmental pollution begin to emerge and environmental problems are directly linked to energy issues. Solar energy is pollution-free clean energy that can be supplied indefinitely and can replace fossil fuels. It is becoming an eco-friendly energy source.

Unlike solar power generation, which converts solar energy into thermal energy, solar cells, which convert solar energy directly into electrical energy, use solar cells made of materials such as semiconductors, dyes, and polymers to convert sunlight It generates electricity and it attracts attention as the most suitable technology for future growth industry.

These solar power generation systems can be largely divided into independent type and grid type depending on whether there is a connection with a commercial power system.

Stand-alone photovoltaic power generation system is a system to supply electric power to the mountainous areas and remote areas where the power system is not supplied. It is independent of the commercial power system and supplies power to the load with only solar photovoltaic power. It can be stored in an energy storage device (ESS) and used for the required time or night.

The grid-connected photovoltaic power generation system is installed on the rooftop, wall, window or ground of a house or a building by directly connecting the DC power from the solar cell to the AC through the inverter and directly connecting to the commercial AC power network. And large-scale power generation systems.

The power output of a solar power generation system fluctuates greatly depending on the amount of solar radiation and temperature, and when the sunlight is incident at a right angle to the surface of the solar cell, the density is greatest. In order to obtain the maximum amount of power, The inclination angle should be optimally set according to the altitude and azimuth of the sun.

Generally, the solar power generation system tracks the position of the sun through power or device manipulation so that the direct sunlight of the sun always enters the front of the solar panel vertically according to the installation form of the solar array (PV array) A semi-fixed array in which the inclination angle of the solar panel is changed vertically or horizontally according to season or month, and a semi-fixed array in which the installation area is limited or the external influence is small. And can be classified into a fixed array fixedly installed at an inclination angle.

Among these, in the case of the tracking type array, a separate power source for the automatic tracking operation, a sensing sensor, a control program, and the like are required, so that the structure is complicated, and there is a limitation in the operation cost burden and maintenance thereof. The output of the power generation is lowered due to the change of the angle of incidence of the sunlight and the generation of shading due to the change of the locus of the sunlight.

On the other hand, semi-fixed arrays are more widely used than stationary arrays because they generate more than 20% of power and are more stable and economical than the tracking array.

As an example of such a semi-fixed array, Korean Patent Registration No. 10-0760043 has proposed a tilting angle-adjustable solar photovoltaic device. However, as shown in FIGS. 1 and 2, A supporting frame 170/172 to which the solar cell 120 is fixed is freely rotatable on the support 110 by a rotation shaft 160. The support frame 170/172 is mounted on the solar cell array 120 Is fixed by the pillars 110, the bolts 182 and the nuts 184 so as to maintain a predetermined inclination angle with respect to the sun. Therefore, when the inclination angle of the solar cell array 120 is adjusted, There is the inconvenience and inconvenience that the fastening state of the bolts 182 and the nuts 184 fixing the installation angle of the support frame 170 is unfolded and disassembled. In this process, the weight of the solar cell array 120 The solar cell There is a possibility that a short circuit or accidents such as breakage of the twist and electrical wiring.

In addition, Korean Patent Laid-Open Publication No. 10-2009-0025724 discloses a structure in which the column is installed back and forth to improve the safety of the structure, the column at the rear is separated into two upper and lower columns, So that the inclination angle of the solar cell array can be changed.

However, due to the structural characteristic of changing the inclination angle by the screw coupling method, it is very difficult to change the inclination angle of the solar cell array by the operator alone when the power generation capacity is large, so that the workability and safety are considerably lowered, There is a problem that power loss due to shading of buildings, clouds, trees, electric poles, artificial structures, or other solar cell arrays located on the front surface can not be effectively coped with.
