Technical Information
Each evacuated tube is composed of two concentric glass tubes; the inner one is coated with highly selective layer and it converts solar radiation into thermal energy, as for the outer one, it is a cover to keep the vacuum. Both of the tubes are fused together and the gap between the tubes is evacuated to achieve excellent thermal vacuum isolation.
