PVSST 1.0 sizing and simulation tool for PV systems

Panoply of tools is available for sizing and simulation of Photovoltaic Systems but none of them fulfill with accuracy our local needs. In order to have a useful tool adapted to our environment, our team is elaborating a photovoltaic Sizing and Simulation Tool (PVSST 1.0). In this article we focus on the Sizing part of the software which is dedicated, as a first step, for Stand Alone PV System (SAPVS) and PV Pumping System. The results obtained for some examples with our software are presented and compared to the results obtained with PVsyst 5.0 and EOS 1.1 (BP Solar). It was found that our sizing tool gives appreciable results even if some improvements must be introduced on it.
