What happens to solar if the grid is switched off |BS Chandra Mohan |Mlife daily

A solar panel will not turn solar energy into direct current until there is a circuit. If there is no circuit, the solar panel will just “sit there” as the photons will not be converted into electricity. ... Without any connection it is just potential energy.

A solar panel is an electron pump that develops a “pressure” or voltage of excess electrons at one end and a scarcity of them at the other end. Think of electrons as like water.

If you take a water pump and connect it to move a water current from one pond to another, but you put a valve at the discharge end and you leave the valve closed, no water will move.

The pump will continue running, pressurizing the system of pipes, but since no water can get out of the pipes, the pump will just get hot and nothing else will happen. The pressure is prevented by the closed faucett from causing a current flow to actually move the water, which could do useful work.

This is what happens in a solar panel where the load is switched off—the pump gets hot—but the pressure is never allowed to create a current. So the solar panel will turn the sunlight into extra heat instead of electron motion.

NOTE: If you put a wire resistance heater or incandescent bulb at the other end and turn the switch on—then an electrical current will flow, and the extra heat that would have been made at the solar panel will be moved and will occur at the light bulb or heater instead of in the solar panel.
