HELIOSTAT CONCENTRATOR PHOTOVOLTAIC POWER GENERATING AND CONTROL SYSTEM

摘要

A photovoltaic power generating system and method, the system comprising: a receiver comprising a dense array of photovoltaic devices; a plurality of mirrors (such as provided in heliostats), each adapted to reflect sunlight onto the receiver; and a control system for controlling the angular orientation of each of the mirrors as the sun moves so that the sunlight is reflected towards an illumination position on the receiver. The control system is adapted to vary the illumination positions of at least a subset of the mirrors over time to provide or maintain a desired total flux distribution over all or part of the dense array. A solar thermal power generating system and method and a hybrid photovoltaic/solar-thermal power generating system and method are also provided.
