In order to efficiently receive sunlight, it is desirable to install the light-receiving surface so that it is always perpendicular to the sunlight, whose incident angle varies depending on changes in latitude, seasons, time, etc.

従って太陽電池の受光面に対する入射光が変化し、斜め
から照射する時には大幅に吸光効率が低下するので、−
日の総吸光量は満足できるものではな（なってしまう。When sunlight is irradiated perpendicularly to the light-receiving surface of the solar cell, it can absorb light with high efficiency, but the incident light on the light-receiving surface of the solar cell changes according to the movement of the sun, and when it is irradiated from an angle, Since the light absorption efficiency decreases significantly, -

It was not suitable for medium-sized or smaller solar cell systems.
このため従来の中型規模以下の太陽電池システムは、そ
の仰角がほとんど固定されて設置されていた。For this reason, conventional solar cell systems of medium or smaller scale have been installed with their elevation angles almost fixed.

You can change it.
