WebAbsorption by ozone takes place in the upper atmosphere at heights above 40 km. It occurs mainly in the ultra-violet region of the spectrum, where it is so intense that very little solar radiation of wavelength less than 0.3µm reaches the Earth's surface. About 3% of the solar radiation is absorbed in this way. Webthe solar constant, 1.353 kW/m. 2; and n is the day of the year. These variations are typically small and for photovoltaic applications the solar irradiance can be considered constant. The value of the solar constant and its spectrum have been defined as a standard value called air mass zero (AM0) and takes a value of 1.353 kW/m. 2. The Nature ...
