The present invention relates to a photovoltaic power generation system having a variable angle adjustment device, and more specifically, it is possible to easily angle the photovoltaic module according to the altitude and position of the sun by using an angle adjustment device using a wire and a pulley. Rather, the present invention relates to a photovoltaic power generation system having a variable angle adjusting device which increases stability by attenuating the force applied in all directions of blue by flexibly constructing a connector connecting the solar array when installed in the water phase.

In general, photovoltaic power generation is a power generation method for converting sunlight into electric power by a solar cell, so that a solar cell made of a semiconductor material receives sunlight and generates electricity.

The photovoltaic power generation is composed of a solar module, a storage battery and a power conversion device made of a solar cell (Solar cell) that generates electricity by the photoelectric effect when the sunlight is incident.

The photovoltaic power generation has the advantages of easy installation and operation and quick installation compared to other power generation methods, but since the power generation is proportional to the installation area, it is necessary to secure a site for installation and operation to secure the desired power generation. Inevitably, it is not easy to secure a site that meets the location conditions.

In order to secure a site that can avoid this situation, it is possible to secure some sites by using a wall, a roof, and a small bare land of the building. However, this also has difficulty in installing and designing a solar cell structure.

(Patent Document 0001) The angle used on the land installed in Registered Utility Model Publication No. 20-0481150 When the control means is applied to the water photovoltaic power generation system, it is difficult to install or operate due to the narrow space at the bottom of the photovoltaic module. There was a problem.

In addition, in the case of angle adjustment using a screw thread installed in Korean Patent Registration Publication No. 10-1708854, the solar module acts as a sail when a strong wind or a blue gust blows in the water phase, and therefore, it lasts longer than 20 years. Inconsistent with the characteristics of the photovoltaic power generation system to be used, there was a problem that the replacement cost is increased due to frequent damage.

In addition, due to the time required to rotate the fine thread several times, there was a problem that the efficiency or the speed of the work is reduced at the same time to be applied to the water-based photovoltaic power generation system.

On the other hand, unlike the photovoltaic power generation system installed in the water, the solar power generation system installed on the water is caused by rolling movements swinging from side to side due to blue waves, pitching movements swinging back and forth, and complex blue waves around. Yawing movements that occur when they occur, or when side and side yaws occur together, Heaving movements shaking in the depth direction, Surging movements moving forward and backward, and left and right yo Swaying) It shall be installed to withstand the movement and other tensions and compression forces.

However, in the related art, there is no device portion that attenuates the force of the blue, and there is a problem in that the structure for connecting and supporting the array and the array in which the solar module is installed is bent or separated.
