Why does the current in solar panels pulse
BUT for a true current source you cannot cause MORE current to flow by applying a heavier load OR by applying extra voltage across the cell. SO If you place a number of current sources / PV cells in series they will each try to produce their rated current at that insolation level. - Download [PDF]
