The cleaning methods for floating solar farms mainly include the following:
Manual cleaning: Use tools such as wrenches, screwdrivers, knives, etc. First, drain the water in the solar energy, remove the cover and ground wire, L, N and temperature measuring wire and other parts, take out the circuit board and heating rod, and use tools to scrape off the scale on the heating rod and magnesium rod. When reinstalling, install the high part first, then the low part, to avoid damaging the circuit board. Finally, do a closed water test to ensure that there is no water leakage.
No-disassembly cleaning: In sunny weather, prepare a 5-10L container, add a pound of descaling agent and 60-80°C hot water, stir evenly and pour it into the water tank of the solar water heater through a funnel. Make sure that the cleaning liquid can fully contact all parts of the water tank, and then soak it in the sun for a day, so that the heat of the sun can help the cleaning liquid dissolve the scale better. Finally, drain the cleaning liquid, fill it with water and rinse it twice to ensure that the scale is completely removed.
Use cleaning equipment: For photovoltaic panels, you can use mops, wipers and other tools to scrub, and then rinse with water to remove pollutants. Be careful to avoid the hottest time around noon, and choose to clean in the morning or afternoon after the sun sets. When cleaning in winter, use less water to prevent freezing. Automated cleaning: You can use photovoltaic cleaning robots, which are divided into waterless cleaning robots and water-washing cleaning robots. Waterless cleaning robots use rotating brushes to clean, which is suitable for water-scarce areas; water-washing cleaning robots use spraying water or detergent with brushes to clean, which is suitable for areas with high humidity or sufficient water resources. These robots can significantly reduce labor costs and water resource consumption, but operation and maintenance costs and water resource recycling and treatment need to be considered.
