Solar Collectors
A solar collector is basically a flat box and are composed of three main parts, a transparent cover, tubes which carry a coolant and an insulated back plate. The solar collector works on the green house effect principle; solar radiation incident upon the transparent surface of the solar collector is transmitted through though this surface ...
Evacuated Tube Solar Collectors
The fact that the collector is a tube with a circular shape, as opposed to a flat plate collector, means that the sun is always hitting the collector at a 90 degree angle throughout the day. This optimizes absorption with passive tracking. The Sunbank collectors are made more efficient by the three target selective coating of Al-N/Al.
