SunOyster 16

08/2021 SunOyster 16 heat receives Solar Keymark certification

The Solar Keymark is a quality mark for solar thermal products based on the standards DIN EN 12975-1 and DIN EN ISO 9806. The Solar Keymark certification also enables subsidies for customers in many European countries. For example, in Germany, customers for solar heating systems or with process heat applications can receive 30 to 55% subsidies on the total system costs.

The SunOyster combines the best of existing solar systems: Concentrated Solar Power (CSP), Concentrated Photovoltaics (CPV) and the low-cost CSP mirrors that track the sun biaxially.
In case of strong wind, the SunOyster automatically closes its mirrors into a secure flat position – just as an oyster closes its shell. Therefore, it can also be installed in the best place for solar energy: On the roofs. When installed on the ground in an unshaded environment, it can be easily mounted on steel anchors or concrete steps.


The heart of the SunOyster is a hybrid receiver which is protected by a borosilicate glass tube. 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 liquid can reach temperatures of up to 110°C. In the version of the purely thermal receiver, higher temperatures of up to 170°C can be reached, e.g. for process heat.


In sunny regions the SunOyster shall produce the cheapest solar energy wherever heat or cold are needed.

Additional Measurement Devices and Control Systems


SunOyster Systems can supply different measurement devices e.g. for the measurement of the direct normal irradiation (DNI) including data loggers and system integration.


Moreover, we can supply control systems to operate your solar cycle with storages, pumps and auxiliary equipment.

Heat Applications


With cost-efficient thermal energy of up to 170°C (SO16heat), the SunOyster opens the door to large range of heat applications.
