It s unit is j min m m this constant is determined by instruments called pyroheliometer. It is defined as the energy received from the sun on unit area exposed normally to the sun s rays at the average sun earth distance in the absence of the earth s atmosphere.

Define the solar constant. Solar constant is defined as the energy received form the sun per unit time on a unit area of surface perpendicular to the direction of propagation of the radiation at the earth s mean distance from the sun outside the atmosphere it is denoted by i on and the latest value of i on is 1395 w m 2 world radiation center wrc has adapted a value of i on 13671w m 2. It is measured on a surface perpendicular to the rays one astronomical unit au from the sun roughly the distance from the sun to the earth. The dimensional formula for solar constant is a m l t b mlt c ml t d mt.

Definition of solar constant. The solar constant gsc is a flux density measuring mean solar electromagnetic radiation solar irradiance per unit area. What is the number value for the solar constant. Therefore it is called the solar constant.

The amount of solar energy striking the top of earth s atmosphere. The 1970 ises congress in melbourne accepted the value of 1353 w m 2 for the solar constant with an error of about 1 5. Solar constant is defined as the amount of solar energy received per minute per unit area of a black body placed on the earth s surface in the absence of earth s atmosphere the area being set at right angles to the direction of the solar radiation. A solar constant is a measurement of the solar electromagnetic radiation available in a meter squared at earth s distance from the sun.
