Abstract

In photovoltaic power system, both photovoltaic module and switch-mode converters show non-linear and time- invariant characteristics, which is very difficult control. In this paper a small 50W photovoltaic module BP-350 is studied. The operating principle is studied and modeling of non-linear equations is done and unknown parameters like series and shunt resistance are calculated. The performance analysis of this 50W photovoltaic module is presented and simulation results are obtained. The characteristics are plotted by varying at different insolation conditions from 100 % to 20%.
