The wavelength distribution of solar energy can be simulated with a black body radiation, the temperature of the black body is 5800K. The wavelength of solar energy is distributed in the ultraviolet, visible and infrared bands. These bands are affected by atmospheric attenuation to varying degrees. Most of the visible radiation can reach the ground, but ozone in the upper atmosphere absorbs most of the solar radiation.
As the ozone layer becomes thinner, especially in the Antarctic and Arctic regions, more and more solar radiation reaches the ground. Part of the incident infrared radiation is absorbed by carbon dioxide, water vapor, and other gases, while the longer-wavelength infrared radiation from the earth's surface at night mostly passes into outer space.
The accumulation of these greenhouse gases in the upper atmosphere may increase the absorption capacity of the atmosphere, resulting in global warming and cloudy weather. Although ozone reduction has little effect on solar collectors, the greenhouse effect may increase scattered radiation and may seriously affect the role of solar collectors.
