कुल सौर विकिरण (Total solar irradiance Meaning in Hindi)
The total solar irradiance is the radiant energy (i.e., the energy of electromagnetic waves) emitted by the Sun over all wavelengths, that falls each second on 1 square meter perpendicular to the Sun’s rays at the mean Earth−Sun distance, measured at the top of the Earth’s atmosphere. It measures the solar energy flux in W m−2 , and is sometimes called solar constant.
