Compared with prior art, the advantage of the invention is that：
The present invention actively turn off formula photovoltaic devices, by set PDLC panels and to transparency conducting layer thereon with it is transparent
Panel applies or cut-out voltage, you can whether controlling the sunlight of photovoltaic module to input, therefore it is defeated to reach active control photovoltaic module
The ability gone out, it has the function of actively to cut off the light source irradiation input of photovoltaic module, therefore can in the environment of needs
Exported with the closing electric energy of active；When component is installed, component actively turns off electric energy output, and installation personnel is in solar irradiation condition
Transported under the conditions of preferable, for installation photovoltaic component without additionally taking measures to prevent electric shock, reducing photovoltaic module should
Operating personnel's safety coefficient is improved with condition；After fire occurs, photovoltaic module actively cuts off illumination input, and fire fighter exists
When stamping out a fire, may not need the electric energy output of misgivings photovoltaic plant remaining component may be to the injury of personnel during putting out a fire to save life and property.
