After the solar water heating system is put into use, it should be managed and regularly maintained according to the characteristics and working conditions of the system to ensure the continuous normal operation of the solar water heating system. This paper analyzes the maintenance methods of various parts of the solar collector system, focusing on the analysis of the cleaning and descaling methods of the solar system.

S.A.P is a distributed central heating system. Each building system is relatively independent, and can be gradually invested according to the progress of the project to increase capital liquidity. The S.A.P system of each building can also gradually invest according to the actual utilization rate, further increasing the liquidity of funds. If you use financial leasing or BOT to rent and sell, use the saved energy costs, and repay the principal and interest, you can get the S.A.P system for free, and the investment is almost “zero”.

The balcony wall-mounted solar collector is the basic component of solar low-temperature heat utilization, and has always been the leading product in the world solar market.

The weather is getting colder and colder, and many people's solar water heaters are no longer used. However, if the antifreeze measures are not done, in the winter, the components of solar water heaters are likely to be frozen. For example, if the pipeline is not well insulated, Pipe bends, over-walls and other parts are particularly easy to freeze, and even cause cracks and leaks to form waterfall ice. Since solar water heaters are generally installed on the roof, water leakage and icing will cause the appearance of the building. Destruction, causing trouble for other households.

A solar hot water system is a device that converts solar energy into heat to heat water. It usually includes solar collectors, storage tanks, pumps, connecting pipes, supports, control systems and auxiliary energy sources that can be used if necessary.

Traditional thermal power generation converts energy stored in fossils into heat by combustion and then into electricity. Solar thermal power generation uses a large number of mirrors to focus the direct light of the sun, convert it into heat by heating water or other working medium, and then use the same process as the traditional thermodynamic cycle to form a high temperature. The high-pressure steam promotes the work of the steam turbine generator set, and finally converts the thermal energy into electrical energy. The principle of the typical solar thermal power generation thermal cycle system is shown in the figure.
