Latest Patents

E J Sletten holds a patent for an "Internal Absorber Solar Collector." This invention features thin solar collecting panels made from arrays of small rod collectors. These collectors consist of a refracting dielectric rod lens with an embedded absorber and a reflecting mirror coated on the back side. The design allows non-tracking collector panels to receive approximately 90% of solar radiation within a 60-degree elevation angle and 120-degree azimuth sectors, achieving a collector concentration ratio of about 3.0. The miniaturized construction of the circular dielectric rods with internal absorbers reduces the weight of the materials used, such as glass, plastic, and metal. The design eliminates the need for external parts or insulation, as heat losses are minimized due to the partial vacuum or low conductivity gas surrounding the heated portions of the collector. The internal absorbers are typically made of solid copper with a black selective surface, and the collected solar heat is extracted at the ends of the collectors using thermal conductivity along the absorber rods.
