What is the reason why solar energy is not hot?

Due to the low amount of sunlight received by the solar tube, it can not be converted in time, and the low heat leads to low heating water temperature. Usually because of continuous rainy weather, the vacuum tube is broken and mixed with air, or the solar energy pipeline is blocked by something, which weathers all the year round and the surface is too dirty, which affects heat absorption.

The reasons for the low water temperature of solar water heaters are summarized as follows: 1. Continuous rainy weather, dark clouds cover the sun, resulting in low solar heat absorbed by solar energy pipes. So these days, the water temperature of hot water is low and the water storage capacity is small, so it can be heated by electric heating. When rainy weather comes, you can boil water in advance and make a good reserve. 2. The external pipeline is too dirty and covered with dust and impurities, which affects the communication between the pipeline and the sun. Solar water heaters mainly rely on external metal pipes to absorb and convert solar energy. If something on the external pipeline blocks the sunlight or is covered with dust, it will affect the direct sunlight. Need to clean the dust and sundries in the external pipeline. 3. The heating device is damaged, and the water level sensor is out of order, so the cold water level cannot be sensed. There is a break in the collector tube to enter air or scale impurities, and the vacuum state is lost, so it is impossible to heat efficiently. It is necessary to clean or repair the vacuum line, and then repair the water level sensor.
