A PV Panel is a Constant Current Source?
A cell can be drawn as a current source with a diode across it. The current source will push the voltage up to the diode conduction point, about 0.6v depending on the chemistry, and there it will stay unless something else loads the cell, ie the thing we are trying to power. Once the thing draw enough current the cell voltage will fall.
