Measurements of thirty minute and daily total solar energy from a small network of specialised ground observation stations are available at a cost recovery charge. Total solar irradiance describes the radiant energy emitted by the sun over all wavelengths that falls each This decision recognizes that no computational model is perfect and that the inputs to each model are characterized by uncertainties that depend on terrain type and environmental conditions, which leads to performance variations across locations. Solar insolation is a measure of solar irradiance over of period of time - typically over the period of a single day. 3D cloud modelling, aerosol tracking and state of the art solar radiation models.
