A system and method for optimizing load current in a string of solar panels a string of solar panels includes a microprocessor coupled to the string of solar panels. The system includes a first DC-to-DC converter comprising input terminals coupled to a load and output terminals coupled to each solar panel in the str...

In a solar panel array, each solar panel in a series-connected string has a current source connected across its output terminals. The current source generates a programmable output current equal to the difference of the load current drawn from the panel and the current corresponding to the maximum power point (MPP) ...
