Description

[0001] The present invention relates to an angle adjusting device for a solar module,

 The present invention relates to an angle adjusting device for a solar module, which can easily change an installation angle of a solar module array according to a change in incident angle of sunlight in a solar power generation system.

Generally, when installing a photovoltaic power generation system using solar light, the output efficiency of the solar cell is considered.

In order to achieve the maximum power generation efficiency, it is best to form an angle of 90 degrees with the solar panel with the solar cell installed.

In order to achieve the above object, there are three methods of adjusting the direction and angle of the solar panel according to the altitude of the sun, namely, a fixing method, a fixed variable method, and an automatic tracking method depending on the installation type of the solar panel.

Conventionally, the above-described automatic solar tracking method for automatically adjusting the direction and angle of the solar panel by tracking the altitude change of the sun has been used as a method for realizing the maximum power generation efficiency.

In addition to the structure for supporting the solar panel, the solar automatic tracking system includes an operation mechanism for moving the solar panel to the position of the sun, a solar tracking for operating the operation mechanism while continuously tracking the position of the sun, .

However, unlike the expectation, the solar cell automatic tracking system is less efficient than the fixed system in which the solar panel is fixed at a certain angle.

This is because the installation cost and operation cost are higher than the fixed type in consideration of the facility cost for the solar tracking and the energy cost consumed for operating the solar panel depending on the position of the sun.

In addition, it is a tendency that it is not installed well in recent years because maintenance is costly because of frequent breakdown.

Therefore, most of the photovoltaic power generation facilities currently being built in Korea are fixed type.

And, it is a tendency to adopt a fixed variable method which is an intermediate form of fixed and tracking method by mixing the advantages of the solar tracking method with the fixed type.

In other words, a fixed variable system that manually adjusts the inclination of the solar panel in accordance with the maximum altitude of the sun, which changes seasonally or monthly, while adopting a fixed method for changing the position of the sun occurring during the day is considered as an alternative.

This system, which can manually adjust the angle of the solar panel, is expected to improve the power generation efficiency relatively well while minimizing installation costs.

What is needed at this time is a device that can manually convert the installed angle of the solar panel.

As a proposal for such a device, the Korean Registered Patent No. 0711550 (manual control method for increasing the power generation efficiency of solar panels according to the seasonal solar altitude, published on Apr. 27, 2007) And an apparatus and a method for constructing an economical power generation system by operating the height of the cradle by adjusting the height of the cradle.

In addition, Korean Patent No. 1035388 (Angle adjustable solar structure, published on May 20, 2011) discloses a solar cell module capable of adjusting the angle of the solar cell module, The present invention relates to an optical structure comprising a fixed frame fixed to a ground at a predetermined interval and supporting an upper portion of the fixed frame, an inclined frame fixed at an upper end of the fixed frame at a predetermined interval, An angle regulating member formed on the support frame and adjustable in a plurality of steps; a rotation bar coupled to the angle regulating member and rotating; An angle adjuster comprising a plurality of solar cell modules arranged at regular intervals on a bar There is a photovoltaic structure is provided.

However, such conventional apparatuses are liable to cause safety accidents of the human body and equipment when the operation is performed.

Normally, when the installed angle of a solar panel is manually changed, a solar cell array having a weight of 400 Kg to 900 Kg is manually lifted or pressed by a human force to change and fix the solar cell array.

Therefore, in the process of changing the angle while handling the large weight of the solar cell array by manpower, there is a high possibility that a safety accident of the human body and equipment occurs.

In addition, there is a problem that the attraction force is increased to cover a large weight of the solar cell array.

In addition, there is a problem that it is difficult to precisely control the angle in the operation of changing the installed angle of the solar panel.
