Concentrated sunlight: how parabolic solar thermal technology works
Parabolic systems do not create electricity first. They focus direct sunlight into useful heat, making them relevant for cooking, hot water, process heating and applied research.
01
The focal principle
A parabolic surface reflects incoming parallel rays towards a focus. In a dish, that focus is a point. In a trough, it becomes a line. A receiver located there absorbs the concentrated energy and transfers it to a vessel or working fluid.
02
Why precision matters
Reflector quality, structural accuracy and alignment directly influence performance. A clean, high-reflectance surface and regular tracking help keep the receiver inside the concentrated solar region.
03
Matching the system to the need
Dish cookers are direct and practical for outdoor cooking, while larger dishes and troughs can be engineered around process temperatures, receiver types and daily thermal demand.
