Insolation is the solar radiation on a Solar Module – in a certain period of time and relative to the surface of the module. Insulation plays an important role in determining the appropriate Angle of Inclination of PV modules as well as the cost-effectiveness of a system. It is usually measured in watt hours per m²; insolation (Wh/m²) divided by time (h) gives irradiation strength (W/m²).
