There is no current, so there's no power loss or thermal stress; It's a normal and expected state of operation. As long as the panel is not short-circuited or connected improperly, being under sunlight without a load does not harm it in any way. But what happens if PV modules, or solar panels, are disconnected when not in use? Disconnection stops energy production, which means missing out on generating electricity that could be stored for later use. Can I Leave Solar Panels Disconnected? Yes, it is ok to leave a solar panel disconnected. The PN junction electric field continues to separate charge carriers; Electrons and holes stay on opposite sides, building voltage; Since the circuit is not closed, no current flows; No energy is. But when the panel is not connected to the grid and no one is taking electricity from it, what is actually happening inside it? A photovoltaic cell is a thin wafer of silicon modified to function as a semiconductor photodiode.
