Abstract

Outdoor characterization of Photovoltaic modules is one of the way to determine their efficiency using MPPT (Maximum Power Point Tracker). However, environmental conditions, namely, dust and particulates, that can attack some components reducing their protecting passivation layer and/or packaging. In this context, the paper presents an experimental attempt to model load resistance used for identifying the maximum current of the PV in order to evaluate the worse condition range within which the MPPT is still capable of finding the working point of the I-V curve. These activities have been carried out on a real system.
