How To Clean Solar Panels For Home Photovoltaic Power Plants? Solar Panel Cleaning Note

After the installation of the photovoltaic power station will inevitably encounter such a situation: dust, leaves, bird droppings, and other accumulation of components on the surface, significantly affect the power generation of the photovoltaic power station, so regular cleaning of photovoltaic power station solar panels is necessary. According to industry statistics, cleaning photovoltaic solar panels can effectively improve the annual power generation by about 8%.

So, how to clean photovoltaic solar panels? How often is the cleaning more appropriate? What is the best tool to clean photovoltaic panels? Today, we answer for you one by one.

From the current point of view, the home photovoltaic power station solar panel owners can clean themselves without exceptional circumstances. There is no need to spend money to find a professional operation and maintenance team.

The solar panel cleaning tools are also relatively common, commonly used high-pressure water gun, soft brush, cotton mop, etc.; these tools are a meager cost and are very convenient.

When cleaning, if there is only a tiny amount of dust on the surface of the solar panel, use the high-pressure water gun for a simple rinse.

If there is sand, mud, and other granular pollutants on the surface, you can first use a high-pressure water gun to rinse away the particles and then use a soft brush to scrub to avoid the particles from sticking to the electric panel.

If there are sticky pollutants such as bird droppings and oily pollutants on the surface, you need to use a clean rag to wipe them off, clean them with glass water, and finally, rinse with a water gun.

In the process of using a high-pressure water gun, pay attention to the pressure of the high-pressure water gun. Too much water pressure may produce damage to the solar panels.

What matters need to be noted when cleaning solar panels?

  • The best time to choose the cleaning time is in the early morning, evening, or night, avoid the noon and other high-temperature time cleanings so as not to cause damage to the solar panels.
  • When cleaning, pay attention to avoid using complex objects, sharp objects directly touching the solar panels.
  • Do not step on solar panels, brackets, and other parts, which can easily damage the power station and affect its service life.

According to the current industry operation and maintenance experience, winter and other rainy and snowy seasons, general cleaning once a month can be (if there is snow phenomenon, to clean up in time), it can clean the rest of the month twice a month. Northwest and other windy, dusty areas, depending on the specific circumstances to determine.

It should be noted that: component cleaning try not to use soapy water; usually, we wash our hands with soap, hands will remain a thin film, the same reason, after cleaning the components with soap, will also leave a film or residue on the surface of photovoltaic modules, will prompt the dust and other faster adhesion and accumulation, affecting the power station power generation. In addition, it is not easy to use other corrosive cleaning agents.
