Method and Apparatus for Reflecting Solar Energy to Bifacial Photovoltaic Modules

摘要

A method and apparatus for using a solar energy reflecting article, encompassing at least one ordered arrangement of reflector elements, each of which elements has a relatively flat, highly reflective face at an angle of primary reflection, with said article designed for a particular solar installation, such that when the article is appropriately placed between rows of bifacial solar photovoltaic modules or underneath the modules, solar energy that would otherwise strike the ground (or supporting surface, such as a rooftop) is instead, when said solar energy strikes the article from at least one angle within at least one defined range of angles relative to the solar reflecting article, reflected onto the side of at least one bifacial module that faces away from the sun. In this manner the article will increase the amount of electricity produced by at least one bifacial solar photovoltaic module.
