  The solar cell panel mount 10 and the solar cell device 1 described above are not particularly limited by the size of one solar cell device or the quantity (scale) in which the solar cell devices are arranged in parallel. However, the effect is particularly remarkable in a large-scale facility where a large number of solar cell devices are arranged. That is, in a large-scale facility, it is necessary to set an inclination angle for a large number of all solar cell devices. Therefore, according to the present invention, it is possible to directly obtain the inclination angle, and the construction can be easily performed. In addition, when such a large number of solar cell devices are arranged, if the accuracy of the inclination angle is poor, the variation in inclination is conspicuous, which is not preferable in terms of appearance. On the other hand, according to the present invention, since the accuracy of the inclination angle is good, the inclination angles are uniform among a large number of solar cell devices, which is preferable in appearance.

  The embodiments that are practical and preferred at the present time have been described above. However, the present invention is not limited to these embodiments, and the gist or concept of the invention that can be read from the claims and the entire specification. However, it should be understood that a solar cell panel mount and a solar cell device with such a change are also included in the technical scope of the present invention.
