At the heart of the collector system lies a high performance absorber. Sunlight, intensified to the equivalent of 13 suns, is focused onto a spherical absorber surface, which is vacuum insulated behind glass. Inside the sphere, a capillary layer (similar to heat pipe technology) ensures that condensate is naturally redistributed based on solar input, where it evaporates again. The steam is returned in a saturated state.

This is an innovative valve controlled system that responds optimally to load fluctuations. As a result, the efficiency remains consistently high even in partial load operation. With a solar thermal output of 300 kW-TH (10 Oktosol), approximately 90 kW-EL can be produced. All components are easy to manufacture according to the current state of the art. A detailed process calculation is available.
