Solar tracking solar power generation device

[0001] The present invention relates to a photovoltaic power generation device, and more specifically, to a photovoltaic tracking type photovoltaic power generation device.

[0002] Solar power generation is the process of converting sunlight into electrical energy using solar panels, which are solar cells. A solar power generation device is composed of a basic structure comprising a solar panel, which is a solar cell that produces electricity when sunlight is incident; a module frame that arranges and fixes multiple solar panels on a surface; a post that allows the module frame to be installed at an angle; and a rotation axis that fixes the module frame to rotate relative to the post, thereby enabling the module frame to have a rotation angle around the rotation axis.

[0003] In addition, a tracking device has been proposed that rotates the module frame relative to the post to ensure that sunlight is always incident according to the movement of the sunlight; this device allows the module frame to rotate according to the direction of the sunlight's movement to track and incident the sunlight. As mentioned above, numerous technologies have been proposed in the past to enable incident sunlight while tracking it.

[0004] Conventional solar power generation systems had problems such as difficulty in adjusting the angle of solar panels or performing maintenance, and the inability to utilize the land three-dimensionally due to restrictions on land use caused by the installation of the systems. Additionally, there was a problem of damage occurring because it was difficult to respond to typhoons or heavy snowfall.

[0005] The present invention is proposed to solve the problems of the conventional technology described above, and aims to provide a solar tracking type solar power generation device that is easy to maintain and enables three-dimensional land use.

[0016] The above-described solar panel is installed along its length direction on the second drive shaft and rotates integrally with the second drive shaft, and rotates integrally with the panel installation member through the rotation of the first drive shaft.

[0017] In the above, the side portion is provided with a plurality of footrests that protrude outwardly, are arranged in an up-and-down direction, and extend along the length of the side portion, and a plurality of support members that protrude outwardly from the outer end of each footrest;

[0018] When the solar panel rotates to be parallel with either of the two side portions by the driving of the first driving unit, the panel installation member faces the footrest and is positioned on the upper part of the support member, and is characterized in that its lower part is supported by the support member.
