Chrome Nickel Vacuum Tube Solar Energy Systems

There are two nested glass tubes. The outer surface of the inner tube is covered with a selective coating which absorbs very high levels of sunlight. The rays entering through the outer tube are absorbed by 93% via the selective surface, but reflects 7% to the outside. The space between the two glass tubes prevents the heat energy accumulated on the sellective surface from escaping through the transport. In this way, the heat loss is reduced to the minimum level. This situation increases the efficiency of the system in winter months. In addition, the round of vacuum tubes during the day to ensure that the sun's rays are always taken upright.

Vacuum Tube Solar Energy Systems are divided into two types as Float and Pressure Systems.
