CONCENTRATOR SOLAR PHOTOVOLTAIC ARRAY WITH COMPACT TAILORED IMAGING POWER UNITS

摘要

Solar panels and assembled arrays include a collection of relatively compact, high-capacity power units. Optical components of each power unit include a front window or surface glazing, a primary mirror, secondary mirror and receiver assembly. Primary and secondary mirrors are defined by respective perimeters, which may be substantially coplanar and in contact with the front window. Some primary mirrors are configured with a perimeter of alternating full and truncated sections, and are curved to a base portion forming a pilot hole. Receiver assembly mechanical components include an alignment tube for mating with the primary mirror's pilot hole and for housing a photovoltaic solar cell. A base plate provided adjacent to the alignment tube serves to radiate heat emitted by the solar cell, and an additional heat sink may provide further passive cooling. A tapered optical rod within the receiver assembly directs received sunlight to the solar cell.
