Maintenance of solar system: do we need to clean solar panels?

When you start to consider installing a solar system, you may have the following questions-
Do I need to clean the solar panel?
How often does it need to be cleaned, and how much does it cost?

Sometimes a large amount of dust and dirt will adhere to the vents of the charger controller or inverter device, which may cause the internal wires to overheat due to low cooling efficiency.
Most inverters include overheating protection, which automatically shuts off when an extremely high operating temperature is detected, so it helps to avoid electrical fires.
Therefore, if the display screen of the controller or inverter transmits wrong information due to the accumulation of dust, it is also a relatively bad situation. In addition, these wiring cables may be damaged or corroded if they are exposed for a long time. Under this potential problem There is a risk of leakage.
Therefore, regular cleaning of these accessories is also an important measure to eliminate potential safety hazards. Sometimes, rain can clean the solar panels for you, so the solar panels do not require frequent manual maintenance. Unless you live in some dry climate areas, it is appropriate to clean every 3 months. As for the other accessories in the solar system, in order to avoid any power failure or risk, a careful inspection every 2 months is enough. One of the easiest ways to clean solar panels is to rinse them with ordinary garden hoses. There is no doubt that it will be more difficult to climb on the roof to wash the panels, but it is worth it. If there is material that cannot be washed off with a normal spray, you can use a soft, sponge-like spatula on the long rod to scrape off the dirty area. Soapy water can be used on solar panels without causing any harm to them. Or if you don’t have the right tools and don’t want to risk climbing, you can call a local professional solar panel cleaning team. Of course, this requires some expense.

For the maintenance of components, only need to ensure:

-No parts deterioration/corrosion

-No debris in the vents

-The switch has no defects

-Wiring is not damaged/not degraded

-Confirm that the accessories and cables are connected firmly

-Electrical inspection to ensure that all components are operating as expected

Maintenance tips for solar power system:
After the snow in winter, you may need to clean the panel. If you are removing snow with water, make sure it is warm. You can also use a long-handled eraser brush. Remember, never use hot water when removing snow from the panel. The panel is made of tempered glass, and the extreme temperature difference between hot and cold water can cause the panel to crack.
★If you don't have time to clean the solar panels, you can install an automatic cleaning device, it will work like an automatic sprinkler system, and you can even make an appointment with a solar panel cleaning company to help with cleaning.
★Do not use abrasive sponges or soap to clean the solar panels, they may scratch the glass.
★If you have to climb on the roof, please be careful, because once you start cleaning, the roof will become smooth due to water, increasing the possibility of slipping, so please use a safety rope for support.
★Do not place the solar panel in a cool place, because when the solar panel cannot absorb any sunlight, its power generation efficiency will be reduced.
