No matter where solar energy is used, there will be scaling problems. Under normal circumstances, tartar should be removed once a year. Otherwise, the temperature of solar energy will be worse from year to year. the quality is poor, do not choose a three-cavity tube (Tube within a tube). Currently, there are three methods of anti-scaling and solar descaling:
(1) Add a magnesium rod with descaling function when installing, but this has no effect, even the magnesium rod itself will be limescale, there is no difference between installed and not installed.
(2) Simply add a descaling agent. I do not recommend this method. General descaling agents are acidic or alkaline and will corrode the water tank liner and vacuum cleaner. tube The scale cannot be removed completely, and the tube must be removed after 24 hours to drain the scale.
(3) Physical descaling method. This involves unplugging the vacuum tube and drying it in the sun for two days, then installing it. Before installing the tube, inject water into it. the solar panel inside, in order to eliminate scale in the water tank. This method will not cause damage to solar energy, save money and completely eliminate scale.
