The term solar radiation is used in many different applications with different meanings. Solar radiation is defined as the energy reaching the Earth from the sun. A large part of this is sunlight, but the solar spectrum extends into the UV and the near-infrared.
Although based on a simplified representation of the underlying physics, the main solar radiation factors are considered and the model is able to characterize the spatial variability of the landscape processes. However, it is designed for modelling of topo- and mesoscale processes and the calculation over large territories is also limited.
Conclusions Solar irradiance is of utmost importance for PV energy generation and can be affected in different ways. To a lesser extent, it is the variation of sunlight reaching the top of the atmosphere due to the sun cycle as well as the variation in sun-earth distance.
