Abstract

Our project consists in designing of an autonomous and portable instrument which allows the on field measurement of IV feature as well as of the main parameters of a single panel and of the whole photovoltaic (PV) in order to compare them with the data provided by the PV panels manufacturer. The comparison between the measured and the provided data allows immediately whether the current panel features coincide with those reported by the manufacturer.

The instrument in question is essentially an electronic load controlled by a microcontroller PIC18FXXX who will trace the IV curve and display principals characteristics of the photovoltaic panel on a GLCD (Graphic LCD), in particular its current of short-circuit, open circuit voltage and maximum power. All this tests are carried out under temperature and solar irradiation conditions.
