More specifically, there are many researches on solar power generation, wind power generation, Research is being conducted to replace the electricity produced by conventional power generation facilities beyond the level of obtaining a small amount of electricity.

In recent years, photovoltaic power generation facilities have become widespread, and in order to supplement the electric energy obtained through the existing power generation means through the photovoltaic power generation facilities, there is a disadvantage that the photovoltaic power generation facilities must be installed on a large scale , There is a problem that a wide flat ground is required for this purpose.
