What are the advantages and disadvantages of flat panel solar and vacuum tube solar energy?
3 good pressure bearing performance. Since the heat absorbing plate of the flat plate solar collector is made of metal material, the collector and the water storage tank are connected with metal parts. Four is a stable performance of large systems. For a large number of places, such as hotels, swimming pools, factories and other places, in the use of solar water heaters, often require a large number of blocks of solar collectors constitute a large-scale water supply system.
High thermal efficiency. Because the vacuum tube solar collector is composed of a number of vacuum tubes, there is a gap between the tubes, in the light of the sun, some of the solar energy has not been accepted by collectors. The flat plate solar collector is a continuous plane, and the surface of the collector can receive sunlight. Therefore, under the same lighting area and sunshine intensity, the average daily efficiency of flat solar water heater is generally higher than the daily average efficiency of vacuum tube solar water heater 6%
Particularly suitable for building integration requirements. Flat plate solar water heater because of its planar structure characteristics in solar building integration application, flexible structure design, without form or size constraints, with easy to implement and building components. In addition, the heat collecting plate is made of metal material, which can be conveniently connected by wire bonding, welding, etc., and provides convenience for installation, maintenance and use.
Flat solar energy: flat solar water heater after decades of development, technology has become more mature and perfect, and has the advantages of other types of solar energy does not have the advantages.
