Having a discussion with a friend.

He asserts that if a panel ( normal household / commercial NOT camping type) is direct connected to a battery, the battery can discharge back into the panel.

My belief is that the panels have diodes at least between the groups of cells and therefore this can't happen.

Anyone know what the facts of the situation are?
