It can not only realize power generation and use and significantly reduce electricity costs, but also relieve the peak load of daytime electricity demand. The roof of the factory is fully utilized, which not only does not need to increase the land area, but also reduces the operating cost of the enterprise.

[0003] According to the principle of geography, the solar altitude angle in winter is obviously lower than that in summer. In most parts of the country, the solar altitude angle in summer can reach 70-90 degrees, and the sunlight is almost vertical. The solar altitude angle in winter is usually 20-50 degrees, and the sunlight is more oblique.
