The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device that increases the light collecting efficiency of a photovoltaic module and reduces its footprint.

In general, photovoltaic technology is distinguished from solar technology using radiant heat energy transmitted from the sun. Solar power generation uses infinite clean energy, which does not require additional energy or driving source, it is easy to construct small to large-scale systems, and it is not affected by the installation restrictions due to environmental problems.

On the other hand, the amount of power generation depends on the sunshine time, in order to obtain a large power, a large number of photovoltaic power generation module is required, it is expensive compared to commercial power, it should be noted that the DC power is obtained first.

The above-described photovoltaic module tracks the position of the sun through power or device manipulation so that the sun's direct sunlight always enters the front of the photovoltaic module vertically in order to maximize power generation efficiency. There are semi-fixed type where the position is changed up and down, and fixed type is fixed regardless of altitude with the sun.

The solar tracking device is a device that moves the solar power module to increase the light collecting while tracking the moving sun. The tracking methods are mainly program tracking and sensor tracking.

Program tracking is a tracking method in which the light receiver is rotated by inputting the movement of the sun due to the rotation and revolution of the earth to the program in advance. Sensor tracking detects the movement of sunlight with a sensor to control the direction of the light receiver, and various improvements have been made in accordance with various related element technologies. Tracking device technology includes solar position detection method, tracking member, tracking driving method, driving power.

An example of a conventional solar tracking alignment method is disclosed in Korean Utility Model Model No. 277771. The disclosed solar tracking alignment method is integrated with a solar module that focuses sunlight and includes a tracker with an encoder that rotates the solar module and detects a rotational position.

Patent No. 044021 discloses a sun tracking method of an automatic sun tracking device. According to the disclosed solar tracking method, when the normal azimuth angle of the photovoltaic module becomes a first angle behind the azimuth angle of the sun, the azimuth angle of the normal line of the photovoltaic module is advanced by a second angle than the azimuth angle of the sun. It has a configuration for driving the power generation module.

As described above, the position tracking device for tracking the position of sunlight has a problem in that its structure is relatively complicated and its position is not accurately fixed. In particular, it is difficult to maintain the set sun tracking angle because the bearing capacity for strong winds is weak.

In particular, since the conventional semi-fixed type can only adjust the angle according to the altitude of the solar light, it is difficult to increase the generation efficiency of the solar light, and there is a problem in that the relative occupancy area is widened by the interference of the shadows of the solar power generator. In particular, since the solar power module cannot be transported according to the azimuth of the sun, the light condensation of the solar light is reduced.

The present invention is to solve the problems as described above, it is easy to adjust the angle of the photovoltaic module according to the altitude of the sun, and to provide a photovoltaic device capable of tracking the photovoltaic module along the sun in the east-west direction. Has its purpose.

Referring to the operation of the photovoltaic device according to the present invention configured as described above are as follows.

As shown in FIGS. 1 to 6, the solar cell apparatus 10 according to the present invention maintains the horizontal state of the photovoltaic module 100 supported by the second sub-frame 13 while maintaining the horizontal state. When the sun rises in the east in one state, the first angle adjusting means 40 is operated to rotate the first sub-frame 12 installed in the north-south direction in the main frame 11 counterclockwise to correspond to the sun. . And a photovoltaic module 100 installed in the second subframe 13 by adjusting the angle of the second subframe 13 with respect to the first subframe 12 using the second angle adjusting means 50. ) Is exposed to the sun as much as possible to receive a lot of light from the sun. Here, the photovoltaic module 100 is preferably set to an angle that can receive the maximum amount of light per day since it can not be followed to squeeze the sun during the day. However, the azimuth angle changes as the sun moves along the ecliptic, and the operator recognizes the azimuth angle of the solar light emitting module and the azimuth angle of the sun, and the operator periodically adjusts the first and second angle adjusting means 40, 50. The angle of the photovoltaic module 100 can be adjusted according to the altitude and azimuth of the sun. Therefore, the solar power module 100 can be repeatedly followed along the sun all day, maximizing power generation efficiency.

When the super strong wind blows, such as a typhoon, the first sub-frame 12 is rotated using the first angle adjusting means 40 with respect to the main frame 11 to maintain a horizontal state. At this time, since the flat portion 21b is installed in the first support portion 21d of the first bracket 21, the first sub-frame 12 is prevented from being inclined in the clockwise direction (see FIG. 1). In this state, the second sub-frame 13 is rotated with respect to the first sub-frame 12 by using the second angle adjusting means 50 to maintain the solar power module 100 in a horizontal state. . This state can protect the photovoltaic device from the strong wind by minimizing the resistance by the wind of the photovoltaic module 100.

As described above, the photovoltaic device according to the present invention can be rotated in the north-south direction and can be highly adjusted, and the solar power generation module can follow the sun in the trajectory of the ecliptic, that is, the east-west direction. It is possible to maximize the amount of power generation by manually or automatically adjusting the angle of the photovoltaic module according to the altitude of the sun by month or season. In particular, since the angle of the first sub-frame can be adjusted according to the seasonal increase in the sun, interference by shadows between the power generating devices can be reduced, and further, the footprint of the solar power generating device can be reduced.
