Product Description
Supreme Solar 250 ETC PC
250 litres Evacuated tube collectors are the most common solar thermal technology in the world.[7] They make use of a glass tube to surround the absorber with a high vacuum and effectively resist atmospheric pressure. The vacuum that surrounds the absorber greatly reduces convection and conduction heat loss, therefore achieving greater energy conversion efficiency.
Supreme Solar models are manufactured with high-standard machinery and precision technology.
Supreme Solar 250 ltr price
Supreme Solar Manufactures products keeping in mind the price, quality and performance, Hence ETC systems are the best for these requirements. As you are aware glass price is much cheaper than Copper used in FPC-type solar, here we save a lot of money in materials costs. Secondly, glass is easily maintainable compared to copper tubes and there is no wear and tear, because of glass transparency solar light is easily captured and converted heat. Hence by using this technology we greatly save manufacturing costs and affordable to the common man

What are Evacuated tube collectors?

Evacuated tube collectors are the most common solar thermal technology in the world.[7] They make use of a glass tube to surround the absorber with high vacuum and effectively resist atmospheric pressure. The vacuum that surrounds the absorber greatly reduces convection and conduction heat loss, therefore achieving greater energy conversion efficiency. The absorber can be either metallic as in the case of flat plate collectors or being a second concentric glass tube (“Sydney Tube”). Heat transfer fluid can flow in and out of each tube or being in contact with a heat pipe reaching inside the tube. For the latter, heat pipes transfer heat to the fluid in a heat exchanger called a “manifold” placed transversely with respect to the tubes.[citation needed] The manifold is wrapped in insulation (glass wool) and covered by a protective metal or plastic case also used for fixing to supports.
Glass-metal evacuated tubes are made with flat or curved metal absorber sheets same as those of flat plates. These sheets are joined to pipes or heat pipes to make “fins” and placed inside a single borosilicate glass tube. An anti-reflective coating can be deposited on the inner and outer surfaces of such tubes to improve transparency. Both selective and anti-reflective coating (inner tube surface) will not degrade until the vacuum is lost.[8] A high vacuum-tight glass-metal seal is however required at one or both sides of each evacuated tube. This seal is cycled between ambient and fluid temperature each day of collector operation and might lead to failures in time.
Glass-glass evacuated tubes are made with two borosilicate glass tubes fused together at one or both ends (similar a vacuum bottle or dewar flask). The absorber fin is placed inside the inner tube at atmospheric pressure. Glass-glass tubes have a very reliable seal, but the two layers of glass reduce the amount of sunlight that reaches the absorber. The selective coating can be deposited on the inner borosilicate tube (high vacuum side) to avoid this, but heat has then to flow through the poorly conducting glass thickness of the inner tube in this case. Moreover, moisture may enter the non-evacuated area inside the inner tube and cause absorber corrosion in particular when made from dissimilar materials (galvanic corrosion).
A Barium flash-getter pump is commonly evaporated inside the high vacuum gap in between tubes to keep the internal pressure stable through time.
The high temperatures that can occur inside evacuated tubes may require special design to prevent overheating. Some evacuated tube collectors work as thermal one-way valves due to their heat pipes. This gives them an inherent maximum operating temperature that acts as a safety feature.[9] Evacuated tube collectors can also be provided with low-concentrating reflectors at the back of the tubes realising a CPC collector.[10]

Hey everyone! To be honest I am really impressed with this product, especially the price point at which it’s selling. So couldn’t resist me from uploading a review on uniletsolar

the best solar water heater i bought, it produces such hot water, you just cant imagine. It’s really dangerous childrens opening the hot water tap, they might burn their fingers. The water is too hot, i seen its boiling and spewing hot water from air vent pipe. This is the reason i called balan, who helped me resolve this issue in such a simple way. As per his suggestions Just covered the tubes with some waste cloths, and removed two buckets of hot water, and the issue resolved.
