Danger from Concentrated Sunlight
Parabolic troughs concentrate solar radiation up to 80 times, parabolic dishes or solar towers up to more than 1000 times. It is better to wear special sun glasses when looking into the focus.

DISS - Direct Solar Steam Generation
The 550 m long DISS trough collector has a thermal power of about 2 MW. Water evaporates directly at a pressure up to 100 bars and is overheated up to more than 400 C.

DISS - Direct Solar Steam Generation
The 11 parabolic trough DISS-collectors for the solar direct steam generation have an aperture width of 5.76 m each.

Dish/Stirling System Eurodish
The European Dish/Stirling system Eurodish was tested here successfully. The mirror concentrates the solar radiation on a focus. It is converted there to heat that drives a Stirling motor and a generator.

SSPS Solar Tower
The 43 m high SSPS tower reaches a thermal power of 2.7 MW. 113 heliostats concentrate the sunlight here.

CESA I Solar Tower
Behind the DISS-system you can see the 80 m high CESA-tower. The heliostats (mirrors) are placed in the North of the tower and provide a maximum thermal power of 7 MW.

CESA I Solar Tower
On the 80 m high tower various concepts for solar tower plants are tested.

CESA I Solar Tower
300 heliostats with 39.6 square meters each follow the sun with two-axis tracking. In one axis the heliostats may only have a tracking errors of 0.06.

Solar Chemistry
Two-axis tracked parabolic trough collectors concentrate solar radiation for chemical processes.

Solar Furnace
Four heliostats with a size of 54 square meters reflect the sun light on a concave mirror. The sun oven can reach a thermal power of 60 kW and temperatures up to 2500 C.
