Description

Solar development system solar location tracking system

The present invention relates to a solar position tracking device for a solar power system, and more particularly, to control the angle of the solar power generation system including a light collecting plate (Solar Cell) to correspond to the movement (trajectory) of the sun. The present invention relates to a solar position tracking device for a solar power generation system that can increase the cost and reduce the manufacturing cost of the angular joint.

In general, power generation systems using solar energy are classified into fixed and solar tracking methods.

In the photovoltaic power generation system divided into the fixed type and the solar position tracking method, in order to maximize the utilization efficiency, the plate-shaped power generation module or the heat collecting plate must face the sun to maximize its efficiency.

In particular, the photovoltaic power generation system composed of the above-described solar position tracking method should always face the sun from the time when the sun starts to rise in the east to the west, and automatically tracks the position (trajectory) of the sun. The control device is provided to face the sun.

When the sun rises from the east, the sun starts at the lowest altitude and gradually moves to the west, passing the highest altitude at the southern midnight, and gradually lowers until it reaches the west.

Therefore, the power generation module or the heat collecting plate should be able to rotate left and right and at the same time has been manufactured and installed in the form of two-axis control that can be rotated up and down.

The conventional technology is designed to track the sun by automatically calculating the sun's trajectory by inputting the longitude and latitude of the location where the power generation system or the heat collecting system is installed according to this logic.

However, in this method, even though the hardness and latitude of the system installation location are the same, an error may inevitably occur in the height of the installation system, that is, the angle of the power generation module or the heat collecting plate facing the sun according to the installation altitude.

In this case, there is a fundamental problem in that the efficiency is lowered due to an error caused by a decrease in the sensing function of the sensor due to a sudden decrease in external temperature.

Accordingly, the present invention has been made to solve the above-mentioned problems, and because the low-cost sensor is provided to fundamentally solve the problems shown in the solar trajectory tracking device, it is not affected by the change in the external temperature, so that the sensing function is more stable. The purpose of the present invention is to provide a solar position tracking device for a solar power generation system that can improve the condensing efficiency as well as the convenience of overload removal and maintenance of the driving unit caused by continuous control and operation. have.
