This paper presents a practical method to detect any accidental partial shadowing on an operating photovoltaic (PV) panel in a smart generation system including a control center. Given a known solar irradiance level and temperature it is possible to make an automatic estimation of the output electrical power and to trigger an alarm in case of an accidental shadowing occurrence. Preliminary field measurements...
This paper presents a novel application of the Design of Experiments (DoE) method as a practical method to detect any dysfunction of an operating photovoltaic (PV) panel. Electrical field measurements data are used to evaluate the PV panel parameters once and for all. A mathematical model describing the variations of the maximum power versus solar irradiance level and temperature was obtained with...
The aim of this study is to show how the Design of Experiments (DoE) Method can be put into use as a practical method to model an operating photovoltaic PV generator. Experiments were carried out and the whole current- voltage characteristics (I-V) were drawn. A mathematical model describing the variations of the Open-circuit voltage (V oc ) and Short-circuit current (I sc ) versus...
