Sudden discharge of solar cell
Now this fits. Most of the cells are still in the flat part of the discharge curve, one or more cells are getting into the upper knee area and tripping off and stopping the charge. Then once the voltages settle back, you have this situation where only a few cells are actually fully charged, and the rest could be anywhere from 30% to 75% charged. - Download [PDF]
