Abstract
The present invention is directed toward a solar power system including an array of photovoltaic panels. The photovoltaic array may include a first module electrically coupled to an AC load and a second module electrically coupled to a DC load. The array may be reconfigured such that individual panels may be transferred from the first module to the second module, and vice versa. The arrays may generate power that is selectively distributed to direct current and alternating current power loads. The system further includes a power management device effective to maximize the power generation of the second module.
