What are the advantages and disadvantages of flat solar and vacuum tube solar energy
Vacuum tube solar:1 fragile, easy to damage, high maintenance costs.2 no overheating protection function3 no frost, minus 20 degrees can not be used normally4 no snow melting snow, snow days showed "hibernation" phenomenon5 not beautiful, installation is not convenient, can only be placed on the roof, increase roof load.6 fragile, not suitable for the realization of building integration7 is not conducive to the use of urban high-rise buildings8 not easy to transport and install9 large gap of glass tube, low effective heat collection area, low heat.10 need to occupy more space.11 easy to scale, can not drink.
6 easy to install, easy to install7 high thermal efficiency, large heat8 large lighting, effective heat area, less heat loss9 water temperature stability, easy control10 long service life11 poor thermal insulation
1 pressure2 has a unique over heat protection function.3 antifreeze antifreeze4 snow melting function, to prevent the phenomenon of solar hibernation5 with the construction of the perfect combination (balcony wall hanging wall hanging wall is widely used in the city high-rise buildings and luxury villas)
