ABSTRACT:
A solar power array includes solar power panels, where each solar panel provides output current and voltage, separate DC-DC converters, where each solar panel is connected to a unique DC-DC converter, where each DC-DC converter is designed to maximize the power from each solar panel, and where each DC-DC converter produces a high voltage output, a high voltage DC bus coupled to the DC-DC converters that receives the high voltage output, and a DC-AC inverter that inverts the high voltage DC on the high voltage DC bus to an AC power signal for distribution to one or more AC loads.
