SunOyster Systems GmbH

The SunOyster is a new concentrating solar technology which converts the direct sunlight into both heat and electricity from the same device, achieving efficiencies higher than anything else available in the market. Up to 75 % of the sunlight can be used to generate 30 % electric and 45 % theat. The heat can be converted into cold easily and economically with thermal chiller. For use in buildings, industry and smart homes. Inspired from nature: The automatic control system closes down the mirrors to a secure position in case of stormy weather - the “Oystering position”. The heart of the SunOyster is a hybrid receiver which combines the best of Concentrated Solar Power (CSP) and Concentrated Photovoltaics (CPV) technology: The 4 m long receiver is protected by a borosilicate glass tube filled with nitrogen. Inside the tube special glass lenses concentrate the light a second time to a geometric concentration of approx. 500 suns. Special solar cells with an efficiency of up to 44% convert the sunlight directly into electricity. The cells are actively cooled by a heat transfer fluid. This fluid, can reach temperatures up to 170 °C. The SunOyster can generate twice as much engergy than modern PV from the same surface. Especially suitable for hotels, offices and private houses with a pool: With this ”Tri-generation“ in sunny regions the SunOyster will generate the cheapest solar energy wherever heat or cold are needed.
