Description

  The present invention relates to a solar panel rotation device, which can efficiently receive sunlight and perform power storage and power feeding operations as time elapses, and in addition, a wind power generation function is also used in combination. The present invention relates to a solar panel rotating device that can improve the efficiency of the solar panel.

  2. Description of the Related Art Conventionally, there is known a wind power generation apparatus using a so-called solar cell or a windmill as a power source that uses natural energy. Of these, solar cells are formed by assembling single solar cells to form a solar panel, and the efficiency is enhanced by installing the surface of the solar panel as close as possible to the direction of sunlight irradiation.

  For this reason, traditional solar panel installations have a solar tracking function, and the solar position and incident angle of the sun at each time of the month are input to the memory. There have been proposals such as making the position of the variable variable.

  However, the solar tracking function known in the past uses a thermal expansion liquid as a drive source, so a solar panel is attached in a situation where there is no irradiation of sunlight such as cloudy or rainy weather and heat cannot be applied to the drive source. It becomes difficult to rotate around the axis. Further, in the conventional example shown as Patent Document 1, the two portions of the shaft and the piston rod are rotating portions, and it is difficult to maintain smooth sliding and rotation over a long period of time. Since the rotating part is exposed to the outside air, corrosion may occur due to rainwater or the like, resulting in a short product life.

Further, in the case of another conventionally known solar tracking method (Patent Document 2), the solar panel is displaced continuously and two-dimensionally corresponding to each time of each month, so that the control becomes very complicated. In addition, the place where the solar panel is installed also needs to be operated by a commercial power source, and the motor serving as the drive source must be limited to the roof top. In addition, a large number of sliding portions for displacement of the solar panel are required, and it is difficult to maintain smooth operation without a failure for a long time.
