What are Evacuated Tube Solar Collectors and How do They Work?
Evacuated Tube Solar Collectors are built with series of clear glass, vacuum sealed tubes with a special selective coating that allows solar radiation to pass through from the outside and traps it inside. This 360 degree collector design is the key principle advantage of Evacuated Tube Solar Collectors – it allows for great absorption earlier and later in the day when the sun is at odd angles for most solar collectors – leading to increased overall system efficiency and cost-effectiveness. The solar radiation then heats the copper heat pipe within the Evaucated Tube, which transfers its heat upward where it is passed to the water moving through the manifold through the specially designed condenser.
