1. A system for regulating power output of multiple solar substrings comprising:
a first set of solar substrings;
a first power regulator comprising:
a first power supply coupled to the first set of solar substrings and configured to receive a first input voltage generated by the first set of solar substrings;
a first adder coupled to a gain control of the first power supply and configured to modify a voltage gain of the first input voltage;
a first modulation signal generator coupled to the first adder and configured to modulate the voltage gain of the first input voltage;
a first de-modulator coupled to the first modulation signal generator and the first power supply configured to de-modulate voltage signals output from the first power supply; and
a first integrator:
coupled to the first de-modulator and the first adder; and
configured to define a voltage gain step for the first input voltage; and

a controller configured to, during a first power cycle:
trigger the first modulation signal generator to modulate a voltage gain of the first input voltage, by a first modulation signal of a first phase and a first frequency, to induce a first oscillating power signal output from the first power supply;
generate a first de-modulated signal at the first de-modulator based on the first oscillating power signal and the first modulation signal;
interpret a first voltage power point condition for the first input voltage based on the first de-modulated signal; and
modify the voltage gain of the first power supply by a first voltage gain step based on the first power point condition and in response to the first input voltage deviating from a maximum power point voltage for the first set of solar substrings.
