Abstract

A power harvesting system including multiple parallel-connected photovoltaic strings, each photovoltaic string includes a series-connection of photovoltaic panels. Multiple voltage-compensation circuits may be connected in series respectively with the photovoltaic strings. The voltage-compensation circuits may be configured to provide respective compensation voltages to the photovoltaic strings to maximize power harvested from the photovoltaic strings. The voltage-compensation circuits may be include respective inputs which may be connected to a source of power and respective outputs which may be connected in series with the photovoltaic strings.

Dependent claims

A system comprising:

a series string of photovoltaic modules comprising at least a first photovoltaic module and a second photovoltaic module,
wherein each of the first photovoltaic module and the second photovoltaic module comprise a first terminal and a second terminal;
wherein the second terminal of the first photovoltaic module is connected to the first terminal of the second photovoltaic module;
and
a compensation circuit, the compensation circuit comprising:
a power converter;
a first input terminal connected to the first terminal of the first photovoltaic module;
a second input terminal connected to the second terminal of the first photovoltaic module and the first terminal of the second photovoltaic module;
a first output terminal connected to the first input terminal of the compensation circuit;
and
a second output terminal connected to a direct current (DC) bus.
