The solar evacuated tube collectors are designed with individual round tubes to capture and convert the maximum amount of sun rays into heat energy for the solar heating system. They are also perfect for a variety of applications such as solar hot water heating, solar space heating or solar pool heating in ice-cold climates. The solar evacuated tubes function in a closed loop, open loop, and drain back solar systems, efficiently even at a temperature as low as -40 degrees C when flat plate collectors may fail to perform. Additionally, there is little chance for weight or roof structural issues with the solar vacuum tubes as they are not required to be filled with large quantities of water. Even if some of the solar evacuated tubes break, the solar system won’t shut down fully. Rather the undamaged collectors will continue to operate until the damaged ones get replaced. However, the performance and efficiency of the solar evacuated tube system differ with a number of factors, including the hot water requirement for each household, outside air temperature, solar collector/roof pitch, collector orientation, and seasonal variation. Buyers always have the option to purchase 20 evacuated tube collectors or 30 evacuated tube collectors which often come included in the package with the frame to mount it on the roof. The desired type of collector can be used individually or connected in series with others to make larger solar systems for producing large volumes of hot water with solar energy.
Modern solar evacuated tube systems are capable to capture around 94% of the sunlight. They greatly suit residential as well as commercial applications working in cold climate regions like North America. Their growing popularity owes to the production of plenty of clean energy with high efficiency.
