The weather is good, but the water temperature of the wall-mounted solar panel on the balcony is not

Generally, there are two reasons why the water temperature of the water tank of the balcony wall-mounted solar water heater system does not increase. The first reason is that the solar collector panel does not fully absorb heat, which is usually manifested by too large collector installation angle or vertical installation. Since the installation angle of the collector is too large, the solar radiation area received by the front side is reduced, which affects the heat absorption effect of the solar collector panel. At this point, the tilt angle of the collector panel must be adjusted. The second reason is that the transmission of solar heat is blocked, which usually manifests itself at the connecting pipe between the heat collector plate and the water tank. When one end of the solar collector's inlet and outlet pipe is lower than the other end, solar heat absorbsed by the collector plate cannot be exchanged with the water tank in time, resulting in large heat retention, making it impossible to heat the water tank, and the water in the water tank still not hot. At this time, the height of the heat collecting plate should be adjusted to ensure a normal height difference, thereby realizing a normal cycle of heat collection management.
