Maintaining solar panels is the key to ensuring their long-term stable operation and efficient power generation. The following are the specific steps and precautions for maintaining solar panels:
First, regular cleaning
Purpose:
Remove dust, dirt, bird droppings and other obstructions on the surface of the solar panels to improve the light absorption efficiency.
Step:
Turn off the power: Before cleaning, be sure to turn off the power to ensure safety.
Choose the appropriate time and tools:
Time: It is best to do it in the morning or evening. Avoid doing it at noon when the sun is strong to prevent the solar panels from overheating.
Tools: Use a soft brush, sponge or clean cloth. Avoid using hard and sharp tools to prevent scratching the surface of the solar panel.
Cleaning method:
For dust and dirt, you can rinse them with clean water and then dry them with a clean cloth.
If the dirt is difficult to remove, you can use a neutral cleaner or a special cleaning agent. Dilute it in proportion and then use it. Avoid using strong acid or alkali cleaners.
Notes:
When cleaning, be gentle to avoid physical damage to the solar panels.
After cleaning, make sure the surface of the solar panels is dry and avoid water accumulation.
Second, check the connecting wires and joints
Purpose:
Ensure that the electrical connection between the solar panel and the inverter, cables and other connecting components is good to avoid current interruption or leakage.
Step:
Regular inspection: It is recommended to check the connecting wires and joints every 1-2 months.
Inspection contents:
Check if the connecting wires are loose or broken.
Whether there is any corrosion or oxidation at the joint.
Handling measures:
If loose or broken connecting wires are found, they should be tightened or replaced in time.
If corrosion or oxidation of the joint is found, sand it with sandpaper and then reconnect it, or replace it with a new one.
Third, prevent shading
Purpose:
Ensure that the solar panels fully receive sunlight to improve the power generation efficiency.
Step:
Installation location selection:
Avoid installing the solar panels in positions where there are tall buildings, trees or other obstructions.
Regular inspection
Regularly clear the weeds, branches and other obstructions around the solar panels.
Fourth, prevent water accumulation
Purpose:
Avoid water accumulation on the surface of the solar panels, reduce scale and corrosion, and improve power generation efficiency.
Step:
Installation design
Make sure the solar panels are installed at a certain Angle to facilitate the smooth flow of rainwater.
Regular inspection
After the rain, check if there is any water accumulation on the surface of the solar panels. If there is any water accumulation, clean it up in time.
Fifth, regular performance testing
Purpose:
Timely detect the performance degradation or malfunction of the solar panels and take measures to repair or replace them.
Step:
Use the testing instrument:
Use tools such as multimeters and photovoltaic module I-V characteristic curve testers to regularly test the electrical performance of the solar panels.
Detection content:
The open-circuit voltage, short-circuit current, output power and other parameters of the solar panel.
Handling measures:
If performance degradation or malfunction of the solar panels is detected, contact professional maintenance personnel promptly for handling.
Sixth, other maintenance measures
Check the bracket and frame:
Regularly check whether the solar panel brackets and frames are firm and whether there is any corrosion or damage.
If loose or damaged brackets or frames are found, they should be tightened or replaced in time.
Prevent the hot spot effect:
Regularly check the solar panels for any obstructions or damages to prevent local overheating.
If the hot spot effect is detected, measures should be taken promptly for repair or replacement.
Lightning protection measures:
In areas with frequent lightning strikes, lightning protection devices should be installed to safeguard the solar panels from damage caused by lightning strikes.
Seventh, maintenance precautions
Safety first
Before carrying out any maintenance operation, make sure to ensure safety, turn off the power supply and wear protective equipment properly.
Professional operation
For complex maintenance operations, it is recommended that they be carried out by professional maintenance personnel to avoid losses caused by misoperation.
Record maintenance logs:
Recording the time, content and result of each maintenance helps to track the performance changes of the solar panels and detect potential problems in a timely manner.
