What happens when solar panels are exposed to sunlight but their output isn’t connected to any system?
In: Engineering
One thing that hasn’t been mentioned in the other (excellent) comments is that the voltage across the two wires will be a good bit higher than the typical rated voltage of the panel. You will see in the specifications of a panel that there is a max power voltage and an open circuit voltage. Basically the electrons are still being pushed by the sunlight and so charge builds up on one side.
