Photovoltaic module, photovoltaic module array, photovoltaic system, and method of detecting failure of photovoltaic module

摘要

The present invention provides a photovoltaic module comprising a photovoltaics and a signal generation means for generating a signal by application of a voltage, wherein the photovoltaics and the signal generating means are connected in parallel and the voltage is a voltage output by the photovoltaics which is connected in parallel with at least the signal generating means, thereby enabling detection of a failed photovoltaic module, regardless of the structure of a photovoltaic module array or the failure mode of the photovoltaic module.
