How to do cleaning and maintainence for solar power system?

Cleaning and maintaining the photovoltaic system is a comprehensive and meticulous process aimed at ensuring the efficient operation and long-term stability of the system. The following are detailed steps and precautions:

1. Cleaning work
Regular cleaning of photovoltaic modules
Frequency: It is generally recommended to clean once every half a month or a month, which can be adjusted according to local environmental and climatic conditions.
Method: Use a dry or damp soft and clean cloth to wipe the surface of the photovoltaic module, and avoid using hard and sharp tools, as well as corrosive solvents and alkaline organic solvents.
Time selection: It is best to do it in the morning or late afternoon, and avoid working when the sun is strong at noon.
Safety precautions: It is forbidden to stand less than 1 meter away from the edge of the roof for work, and it is forbidden to clean in severe weather conditions such as strong winds, heavy rain, thunderstorms or heavy snow.
Clearing shelters
Regularly clean the bird droppings, leaves and other shelters on the photovoltaic modules to ensure that the photovoltaic modules can receive sunlight to the maximum extent.

2. Inspection work
Bracket inspection
Check whether all bolts and welded bracket connections of the bracket are firm. If there is any looseness or cracking, repair it in time.
Inverter maintenance
Check whether the inverter structure and electrical connections are intact and free of rust, and disconnect the AC output side circuit breaker once regularly.
Ensure that there should be no large vibration and abnormal noise when the inverter is running, and the cooling fan should start and stop automatically according to the temperature.
Line inspection
Regularly check whether the photovoltaic power generation line is connected normally, whether there is a poor line connection or line shedding, etc.
Check whether the cables and connectors are damaged or aged, and replace and maintain them in time.
Merger box maintenance
Check the appearance of the DC combiner box, wiring terminals, high-voltage DC fuses, output bus insulation resistance, DC circuit breakers and lightning arresters to ensure their normal operation and safety performance.

3. Monitoring and data analysis
Real-time monitoring
Establish a complete monitoring system to monitor the power generation, temperature, voltage and other parameters of the power station in real time.
Use advanced monitoring systems to track the power, power generation, voltage, current and other parameters of the components to detect and handle abnormalities in a timely manner.
Data monitoring
Through data analysis, identify potential problems in system operation and take measures to intervene in advance.

4. Safety and maintenance management
Develop operating procedures
Photovoltaic power stations involve power transportation, panel installation and system maintenance, and detailed operating procedures need to be developed to ensure the safety and standardization of operations.
Establish emergency plans
Establish corresponding emergency plans for various possible faults and problems to ensure that they can be responded to quickly when problems arise.
Conduct safety training
Regularly conduct safety training for operation and maintenance personnel to improve their safety awareness and emergency response capabilities.
Maintenance cycle development
According to the operation status of the equipment and the manufacturer's recommendations, formulate a reasonable maintenance cycle to ensure that the equipment operates in the best condition.

5. Environment and safety
Environmental safety
Ensure the safety of the surrounding environment of the photovoltaic power station to avoid fire, theft and other incidents.
Equipment protection
It is prohibited to trample on photovoltaic power generation systems such as solar panels, brackets, cable trays, etc. to avoid damage.
In summary, cleaning and maintaining the photovoltaic system is a comprehensive task that requires comprehensive consideration of multiple aspects. Through regular cleaning, inspection, monitoring, data analysis and safety maintenance management, the safe and stable operation of the photovoltaic system can be ensured, and the power generation efficiency and operation management level can be improved.
