(Definition in Hindi) 1. The solar constant (S0) is the amount of incoming solar electromagnetic radiation per unit area at the mean Earth−Sun distance, measured on the outer surface of the Earth’s atmosphere, in a plane perpendicular to the rays (in W m-2). As this value is not constant in time, the term total solar irradiance is often preferred in recent years.
