<p>A photovoltaic module capable of being electrically isolated and an electrical isolation method thereof. The photovoltaic module is composed of a plurality of solar battery modules (1) which are interconnected, wherein the power output circuit of each solar battery module (1) is connected with a breaker. When an interruption of power supply is required as in emergency, the electric connection circuit of the photovoltaic module is utilized to load and transmit a power interruption signal. The power interruption signal triggers each breaker to cut off the power transmission line of each solar battery module (1), thus the whole photovoltaic generating system stops outputting power. When the emergency is lifted, the power interruption signal is disconnected so that the breaker is switched on to turn on the power transmission line of each solar battery module (1), thus the power supply is normal. The photovoltaic module has the advantages of simple structure and reliable operation.</p> |
