Solar energy is the energy produced by the continuous nuclear fusion reaction process inside the sun. The average solar irradiance (radiation intensity) in the earth’s orbit is 1367kw/m². The circumference of the earth’s equator is 40000km, so it can be calculated that the energy obtained by the earth can reach 173000Tw. The standard peak intensity …
