Photovoltaic Modules, Curve Tracer, I-V Curve, P-V Curve, Sampling Frequency
Abstract
The I-V and P-V curves are an effective way to analyze the efficiency and degradation of photovoltaic modules. Devices known as photovoltaic characterizers are responsible for plotting these curves and typically use the same sampling frequency to obtain all points of the curve. Since the maximum power region is of great interest, this work proposes a methodology that models this region with higher resolution, providing superior accuracy. Tests were conducted in various scenarios demonstrating the efficiency of the methodology.
