1. A method comprising:

  • performing maximum power point tracking of a plurality of power sources connected respectively to inputs of a plurality of power converters;

    converting input power received at the inputs of the plurality of power converters to output power on outputs of the plurality of power converters; and

    regulating a voltage across a pair of terminals to a fixed constant value, the pair of terminals having connected therebetween, the outputs of the plurality of power converters connected in a series string, current in the series string varying in response to the input power varying and in response to the fixed constant value of the voltage across the pair of terminals.
