1. A method for generating a three phase ac mains power supply from a plurality of photovoltaic panels, the method comprising:

  • connecting dc power outputs from the plurality of photovoltaic panels in parallel to an input of a power conditioning unit; and

    converting an input flow of dc power from the dc power outputs into the three phase ac mains power supply using the power conditioning unit, wherein the converting comprises converting the input flow of dc power into an intermediate flow of dc power on a dc link of the power conditioning unit coupled to an energy storage capacitor having a ripple voltage that is proportional to the intermediate flow of dc power on the dc link, and converting the intermediate flow of dc power to the three phase ac mains power supply with a dc to ac converter that is controlled to maximize the ripple voltage on the energy storage capacitor.
