All Glass evacuated solar collector tubes are the key component of the Solar Collectors. Each evacuated tube consists of two glass tubes. The outer tube is made of extremely strong tran***rent borosilicate glass that is able to resist i***ct from hail up to 25mm in diameter. The inner tube is also made of borosilicate glass, but coated with a special selective coating, which features excellent solar heat absorption and minimal heat reflection properties. The air is withdrawn (evacuated) from the ***ce between the two glass tubes to form a vacuum, which eliminates conductive and convective heat loss. Unlike other types of solar collectors, evacuated tube solar collectors still provide excellent results on cloudy days. This is because the tubes are able to absorb the energy from infrared rays, which can pass through clouds. Wind and low temperatures also have less of an effect on the function of evacuated tubes when co***red to flat plate solar collectors due to the insulating properties of the vacuum.
As the key components of the solar collector, the evacuated tube is a production that is optimized in geometry and performance.
