This product is the All-glass Evacuated Solar Collector Tube
The all-glass evacuated solar collector tube consists two concentric cylindrical glass tubes, the inner cylindrical tube is the absorber tube on which solar selective coating is sputtered, the jacket between the two glass tubes are evacucated to extremely low vacuum to reduce the heat loss by free convection and conduction. Top quality tubes increase the solar yield of your solar system and reduce the aging problem. This technology can be utilized under all kinds of climate conditions, especially better in colder area.
Features of this All-glass Evacuated Solar Collector Tube
High absorptance a>0.93 (AM1.5) and low emittance e
