It depends on whether the installation angle is correct. The best installation angle is around 60 degrees. If installed at a 90 degree right angle, the wall mounted solar panel will not be exposed to sunlight and will not be exposed to sunlight. capable of heating. There is a shield in front of the wall-mounted solar panel that blocks sunlight. The sun cannot shine on the wall-mounted solar panel. The inner tank of the wall mounted solar panel is broken and the wall mounted solar panel will not generate heat.
Due to the long-term use of wall-mounted solar power, the pipes of wall-mounted solar power will inevitably contain scale and other debris if not cleaned in time, problems such as pipe blockage will occur. waste water must therefore be drained immediately.
After the wall mounted solar power is no longer hot, wipe the dust on the surface of the vacuum collecting tube and the reflector, and remove the obconstruction; replace the vacuum collection tube; replace the heat pipe; ; use an auxiliary electric heater; Tighten the valve to prevent leakage or check the quality of the valve and replace the water valve parts.
Compared with vacuum tube solar water heaters, wall-mounted solar water heaters have slightly lower heat collection performance. It is also abnormal for a wall-mounted solar water heater to maintain a temperature of 8 degrees for a long time.
