Description

Solar power gensration apparatus for growing plant that can be installed in plantation

The present invention relates to a photovoltaic device, and more particularly, to a photovoltaic device capable of cultivation of plants in a region where the photovoltaic device is installed.

Typically, solar technology is distinguished from solar technology that uses radiant heat energy transmitted from the sun. The power generation using solar energy uses infinite clean energy, so there is an advantage that no separate energy or drive source is required, and the construction of a large-scale system is simple at a small scale and is not affected by installation restrictions due to environmental problems.

On the other hand, it is important to note that the amount of power generation depends on the sunshine time, that many solar power generation modules are required to obtain large power, are more expensive than commercial power, and that DC power is first obtained.

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

The solar tracking device is a device that moves the solar power module to increase the light collecting property while tracking the moving sun. The tracking method is largely divided into program tracking and sensor tracking. Program tracking is a tracking method that rotates the light-receiving body by inputting the rotation of the earth and the movement of the sun in advance into the program. Sensor tracking is a sensor that detects the movement of sunlight and controls the direction of the light receiver, and various improvements have been made in accordance with advances in various related element technologies. The tracking device technology includes a solar position detection method, a tracking member, a tracking driving method, and driving power.

An example of a conventional solar tracking alignment method is disclosed in Korean Registered Utility Model No. 297771. The disclosed solar tracking alignment method is integrated with a solar module that focuses sunlight, and includes a tracker with an encoder that senses a rotational position while rotating the solar module. Patent No. 044021 discloses a solar tracking method of an automatic solar tracking device.

In the disclosed solar tracking method, when the normal azimuth angle of the photovoltaic module is lagging the first angle by the azimuth of the sun, the solar light so that the azimuth of the normal of the photovoltaic module precedes the azimuth of the sun by a second angle. It has a configuration to drive the power generation module.

Patent registration No. 0483291 discloses a method for tracking the solar location of solar-related equipment, and registration patent No. 0369897 discloses a hybrid solar tracking control device for a condensing solar collector, and registration utility model No. 0404291 A solar tracking device having a light collecting unit for photovoltaic power generation is disclosed, and in Utility Model Publication No. 199-00186, an angle adjustment device for a solar panel by wireless calling is disclosed.

As described above, a solar location tracking device that tracks the location of sunlight has a problem in that its structure is relatively complicated and the location is not accurately fixed. In particular, it is difficult to maintain a set sun tracking angle due to weak support for strong winds. Since the conventional semi-fixed type can adjust only the angle according to the altitude of the solar light, it is difficult to increase the power generation efficiency of the solar light, and there is a problem in that the relative occupied area is widened by the interference of the shadows of the solar power device.

On the other hand, as the photovoltaic power generation device receives the photovoltaic power generation module from the photovoltaic power generation, the construction of the photovoltaic power generation device requires a relatively large area of land or a lake, etc. Do. However, recently, there is not enough land to install photovoltaic power generation modules, so it is installed in cutting grounds, quarries, and slopes.

In view of this, the Korean Patent Publication No. 2014-0052719 discloses an organic shade plant cultivation facility, and the Korean Patent Publication No. 2010-123130 discloses a sunlight blocking structure for cultivating a shade plant equipped with a solar cell.

The facility for cultivating such a shade plant has a problem in that a photovoltaic module cannot be installed in a one-way farm.
