Abstract: A method for deriving a predetermined unit of power from a power generator using a renewable energy source is disclosed. It comprises determination of a power generation capacity of the power generator, by a control unit, based on application parameters received by the control unit associated with generation of the predetermined unit of power, operational parameters associated with the power generator, and environmental parameters associated with a location of derivation of the power from the renewable energy source. A value of resistance is then determined by the control unit to reduce power loss during power generation, wherein a resistor unit having the determined value of resistance is electrically coupled with the power generator. The control unit then derives the predetermined unit of power across the resistor unit from the power generator.
