Model Validation of Photovoltaic Systems

This paper presents a methodology for photovoltaic (PV) systems model validation through outdoor measurements. The paper first summarizes a PV model published by the authors in [1] which allows to precisely reproduce the current- voltage relationship of an array of an arbitrary size from information available in manufactures´ datasheets. The model is then validated through the methodology proposed herein under different PV panels configurations as well as under variable solar irradiance conditions.
