SunOyster Systems is a Hamburg based start-up developing a new concentrating solar technology which is able to convert the energy of the sun into both electricity and heat. With the "SunOyster Technology" we combine the best of Concentrated Solar Power (CSP) and Concentrated Photovoltaics (CPV) technology to beat PV to a new concentrating solar technology which produces both heat and electricity from the same device, with a total efficiency up to 75%. And as cooling is mainly required when the sun is shining, it is our objective too to use the abundant solar energy to generate cold. With the help of thermal chillers the SunOyster can convert the heat into cold.
Semi-parabolic mirrors follow the sun all day and concentrate the sunshine on a line. In this line, the 4 m long receiver. receiver is protected by a borosilicate glass tube filled with nitrogen. Inside the tube, special glass lenses concentrate the light a second time to reach 500 times the power of the sun. Highly efficient (44%) solar cells developed for spacecraft convert this directly into electricity. The cells are liquid cooled but remain operational at temperatures up to 170°C. The heat extracted from cooling the receiver can therefore be used at the temperature level of process heat. The proprietary control system of the SunOyster tracks the sun automatically all day from East to West. It allows online monitoring of the SunOyster, so that the customer can admire the energy generation via their mobile phone. In case of danger like storm the SunOyster mirrors close into a secure flat position. This allows to build the system light and cheap and it can be easy installed.
