Supporting device for solar power generation {SUPPORTING APPARATUS FOR SOLAR POWER GENERATION}

The present invention relates to a support device for solar power generation.

For various reasons, including environmental issues and depletion of fossil resources, technology development for the production, distribution, and use of so-called renewable energy is actively underway. Among new renewable energies, solar energy is capable of continuous energy production as long as the sun exists, so it can be used indefinitely if used on Earth. Compared to wind or hydropower, solar energy can be installed on a small scale, making it easy to enter. It has many advantages, including the fact that it is environmentally friendly as there are no substances or phenomena that cause environmental pollution during the production process, so it is currently receiving the most investment and installation. For example, it is easy to see solar panels installed in highway rest areas, on the rooftops of buildings, and in ground parking lots to also block sunlight.

In order to effectively produce solar energy, that is, to produce the highest power from the same amount of sunlight, sunlight must be irradiated close to perpendicular to the solar panel. Since the altitude and azimuth of the sun change according to the rotation of the Earth, the solar panel In order for sunlight to continuously be incident vertically (even if it is not vertical, as close to vertical as possible), solar panels have no choice but to continuously follow the sun. In other words, the elevation angle and azimuth angle of the solar panel must be controllable.

Therefore, a tracking device for solar power generation that can control the elevation angle and azimuth of these solar panels has been proposed.

However, the conventional tracking device for solar power generation generates a large load as a large number of solar panels are rotated by one actuator, and as a large number of fixing fixtures are used to fix the solar modules, the configuration is difficult. There were complex problems and frequent breakdowns.

That is, the pipe clamp 150 fixes the rotating pipe 130 and the torque tube 400. Therefore, the rotation pipe 130 rotates the torque tube 400.

The module frame 300 is extended and connected in the horizontal and vertical directions, respectively, and accommodates solar modules P1 and P2 therebetween. A plurality of supports 200 stand upright from the ground and support the upper structures. For example, the supports 200 may be spaced apart from each other with the actuator 100 in between and may support the actuator 100 and the torque tube 400 connected to the actuator 100. Here, a fixing part 160 is fastened to the tip of the support 200, and a rotating body 140 is installed on the upper side of the fixing part 160.
