I was thinking about a power circuit in which the power can be supplied on the same rail through a solar panel or an ac adapter. I automatically thought to add diodes in series to form an OR gate, so the panel wont supply the ac adapter and vice versa. But then I thought- do I really need to protect the solar panel from reverse current? What would actually happen?
What happens if you supply power to the solar panel, not from it? I would appreciate all help.
