Classification of Electric Faults in Photovoltaic Systems Based on Voltage-Power Curves

This article presents the development of an algorithm capable detecting and classifying electric faults in photovoltaic array systems by measuring voltage-power curve. The was build based on a characterization method which multiple arrays were evaluated under different fault conditions, analyzing curves at output each array. experimentally controlled environment inside laboratory 59 conditions obtaining effectiveness 100%. Then, outdoors 124 temperature solar radiations, able to detect classify with 94.4%. proposed can be implemented standard power-inverters as low-cost solution users receive information up-to date performance their through mobile App. design app for is well.
