insolation

(solar irradiance)
(solar energy received per unit area in given time)

Insolation (or solar irradiance) is the amount of solar EMR energy striking a given amount of surface during a given time interval. Some units:

The amount is dependent upon the distance from the Sun and the angle at which it is striking the surface and is of particular interest regarding solar power generation on Earth, as well as its effect on temperature and weather.

The term is also used for off-Earth situations, i.e., other solar system bodies and sometimes for extra-solar planets regarding radiation energy from their host star.
