Modeling of athmospheric phenomena for photovoltaic systems

Nowadays; renewable energy sources like wind and solar energy are considered as the best solutions to substitute the fossil sources due to their big advantages such as: renewability (never finish), safety, etc. However, the cost of such resources stills to be the great inconvenient. Among other countries, Algeria is known to be a wide country with good solar potential which could exploit this energy in some applications; electricity, pumping, etc. So, in order to reduce the last disadvantage (cost), many researches are done using two different ways: (1) The first one is realized by improving the conversion efficiency based on the study of the material proprieties, (2) And the second is based on the proposition of optimal designs and appropriates sizing of the overall renewable systems. So, and in this context, our paper is based on the second approach. In fact, first we modelize the atmospheric phenomena in order to determine the available solar energy, then we propose adequate design and sizing of our system to attempt the best performances basing on the panel proprieties. At the end, we make a comparison between the obtained results and the real measurements will be done in order to validate the proposed approach. This study can help us to make some economical prevision for any place and country.
