Modelling solar data: reasons, main methods and applications

The main aim of this research work is to analyse the importance of modelling solar data. Should engineers and scientists spend time modelling solar data from other variables or it is a simply waste of time? Which applications truly need a precise forecast of the solar variables? Which spatial and time resolution is needed? In this work we have proposed to analyse these questions and give a brief description of the currently existing methods and the targets demanded by industrial and scientific applications in this field. In the field of modelling solar data there exist many methods and techniques which cannot be completely described here. The authors just want to analyse the relevance of improving these methods for the development of the solar energy.
