Solar panel maintenance: Everything you need to know

1. Maintenance of solar panels
2. Maintenance of inverters and various control systems
3. Maintenance of wiring systems and various connection systems
4. Maintenance of battery system

Maintenance of solar panels

• Solar panels should be checked and cleaned every 6 months. But if you feel that the performance of the solar cells has decreased, they can be cleaned as well.
• Cleaning dust and grime from solar panels is very easy. Just rinse or spray with clean water and wipe away the grime. If the stain is rubbery or difficult to remove, try washing it with cold water and scrubbing with a sponge.
• To clean the solar panel, do not use sharp objects, scotch bristles, or brushes with hard bristles. Including strong corrosive liquids to clean. Because it can cause marks on the surface of the solar panel. If there is a mark, it will block the sunlight. This causes the efficiency of solar panels to decrease.
• The best time to clean solar cells is in the morning or evening. Because this is the time when solar cells do not receive sunlight. The panel will not get hot. Makes cleaning the panel convenient.

Maintenance of inverters and various control systems

• Electrical converters or inverters and various control systems of solar cell systems There is an easy way to check the basic condition. Just see if there is dust accumulated or not. If there is dust, use a dry cloth to clean these devices to keep them in a dust-free image.
• If you want to inspect it more closely, use a flashlight to look at the seams inside the equipment to see if they are in good condition or not. If you find that there are damaged or unusable points, such as cracks in the equipment, broken wires, or loose wires, fix them as quickly as possible.
• The inverter and control system are in the form of a box. Therefore, we must be careful not to make it a source for insects, rats, or other animals to nest. If found, get rid of it to prevent problems with the system in the future.

Maintenance of wiring systems and various connection systems

• Inspecting the wiring system and connection system is another important point that should not be missed. You should check whether the various equipment is in perfect condition or not.
• There are cracks, cracks, burn marks, corrosion marks on the wires. Has deterioration of the insulation and pipes occurred? Is the ground wire still good? Or is there a spark when turning on the light switch? If you find an abnormality, immediately notify a professional technician. Or the person who came to install it should come and fix it immediately.
• Maintenance of the electrical wiring system should be inspected no different from maintenance of solar panels, that is, every 6 months.
• We recommend that you check the condition before the rainy season as it will make maintenance easier than during the monsoons.

Maintenance of battery system

• A good battery must be in perfect condition, looking clean, and free of dirt. No corrosion or leakage of electrolyte solution inside the battery.
• In checking the condition of the battery, we will mainly notice cracks around the battery pack. Look at the amount of electrolyte solution to see if it is too little or not. Are there any corrosion marks around the battery terminals? Including checking the voltage level of the battery, etc., if there is an abnormality The problem can be solved as follows.
• If the amount of electrolyte solution is too little, add more to normal use level.
• If there is corrosion around the battery terminals, which usually appears as a white stain. Clean it at least once a month.
• Voltage levels should be checked regularly. When there is an abnormality, check or replace the battery as quickly as possible.
