Abstract
Method for detecting an electric are in a photovoltaic device by ultrasound, comprising measuring at least one parameter among the amplitude, the duration and the central frequency, of an electrical signal received by an ultrasound sensor; and comparing the measurement of this at least one parameter of the electrical signal with predefined values in order to determine whether the measurement corresponds to that of an electric arc.
