(1874):

Like in a thermos flask the heat canbe stored for a long time.

This allows to operate the collectorwith high efficiency even in timeswith low solar irradiation or at hightemperatures.

Due to the material (pure glasstube) the design is very durable.

Vacuum

is the best physical insulator !

Double wall glass tubes

+ cylindrical evacuatedabsorbers

Copper, steel or stainless steel collector tubes + CPC reflector

CPC = Compound Parabolic Concentrator

Direct irradiation

Best possible solar yields at all weather conditions.

Sidewise irradiation Diffuse irradiation
