Description

  The present invention relates to a solar panel mount, a solar panel mount driving apparatus, and a program.

  Conventionally, solar panels are installed on the roofs and mounts of buildings, and are used to collect solar energy, convert it into electrical energy, and generate electricity. Moreover, by making the light-receiving surface that receives sunlight in the solar panel face the sun, the power generation efficiency is improved as compared with the case where the light-receiving surface is arranged obliquely with respect to the sun. However, the azimuth and altitude of the sun always change from the point where the solar panel is installed.

Therefore, a solar panel is mounted and one end can be rotated, a driving device that moves the other end of the gantry up and down along a column installed on the other end of the gantry, and so that it can face sunlight A solar panel mount comprising an elevation angle setting device capable of adjusting the elevation angle of the light receiving surface of the solar panel has been proposed (see Patent Document 1).
According to the technique of Patent Document 1, the other end of the mount on which the solar panel is mounted is moved up and down, and the elevation angle of the light receiving surface can be adjusted so that the light receiving surface can face the sun. To do.

  By the way, the sun usually rises from east to south and sinks to the west. For this reason, the solar panel pedestal described in Patent Document 1 is installed with the light receiving surface of the solar panel facing the south side, for example, one end that can be rotated is arranged on the west side, and the other end is placed upward every predetermined time. By moving to, the light receiving surface can face the sun.

  However, in the region where the latitude is higher than the equator, the sun rises from the northeast and sinks to the northwest in the vicinity of the summer. At this time, the solar panel mount described in Patent Document 1 cannot receive light at all when it is installed with the light receiving surface of the solar panel facing the south side. On the other hand, if the solar panel's light receiving surface is installed from the south side toward the northeast side in consideration of the position of the sun near the summer solstice, the afternoon sunlight cannot be received, and the light receiving surface is installed from the south side toward the northwest side. Then, the morning sunlight cannot be received, and the power generation efficiency is significantly reduced.
