Vacuum tube and flat plate solar energy performance of PK

  At present, the world market for solar energy solar flat plate and the vacuum tube solar water heating system of coexistence, from the point of market share, China mainly to the vacuum tube, vacuum tube accounted for 86%; Europe and the United States and other developed countries is the exact opposite, plate type accounted for more than 90%. This situation is caused by history and characteristics.

  Flat plate solar high thermal efficiency, long service life, reduced maintenance, reliable operation, and the building of the combination of appearance, flexible installation, is not restricted, bearing operation, antifreezing antiscaling, any area in any season can use, strong practicability, so in the developed area has become the mainstream product. And the vacuum tube solar water heater because of low efficiency, short life, the operation is not reliable, high maintenance, high maintenance cost, difficult to achieve and building integration, installation is limited, not beautiful, easy to freeze in winter, not in alpine region. So the poor usability, in the use of less developed area. But in China, because of its cheap price, not tall to the installation requirements, so sales, has become the mainstream of the domestic market.

  Vacuum tube solar products after ten years of market testing, has been exposed many serious problems, in order to solve these problems, enterprises and research institutions have devoted a lot of manpower and material resources, but these problems are caused by the products of its own structural defects, so difficult to work. Recently, several large domestic vacuum tube water heater manufacturers already prepared to the flat transition. In the not too distant future, will become the mainstream of flat plate solar energy efficient solar energy in China, in the high-end market.
