With the SunOyster Technology we combine the best of Concentrated Solar Power (CSP) and Concentrated Photovoltaics (CPV) and PV. The "SunOyster 16" (SO 16) is a patented concentrating solar collector with roughly 16 m2 gross mirror surface. It tracks the sun bi-axially to convert the energy of the sun into both electricity and heat (the SunOyster can convert 75 % of the solar radiation), trying to represent the cheapest form of solar energy with the best surface efficiency.
In addition it can turn heat into cold. The renowned EU grant for the project „SOcool“ focuses on the combination with thermal chillers for solar cooling of buildings and industry in order to satisfy their complete energy demand from power over heat to cold.
With this ”tri-generation“ from electricity over heat to cold the SunOyster can provide the complete energy demand – and this at lower costs than the electricity grid or fossil energies.
The heart of the SunOyster is a hybrid receiver which 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 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 relation to a horizontal roof or ground surface the SunOyster generates at least twice as much energy as photovoltaics.
