Definition - What does Insolation mean?
Insolation, also known as solar irradiance, is the power which is produced in a pattern of electromagnetic radiation by the Sun. It can be measured at the surface of the Earth or in space after atmospheric scattering and absorption. It varies based on the solar declination, latitude, atmospheric conditions, time of the year and the distance between the Earth and the Sun. It has a great impact on the temperature. The greater the Insolation, the higher the temperature will be.
Petropedia explains Insolation
When Insolation reaches an object, a part of it is absorbed by the object and the remaining is reflected back. The absorbed radiation is generally converted into thermal energy and thus increases the temperature of the object. Some natural and man-made systems convert the absorbed radiations to other forms liked chemical bonds or electricity in plants or in photovoltaic cells. Insolation is largest on a surface when it faces the Sun directly. When the angle between the Sun and the surface moves, Insolation reduces. Moreover, Insolation is received if the duration of the daylight is longer as it depends on the duration of the daylight.
