After the installation of photovoltaic power station, will inevitably encounter such a situation: dust, leaves, bird droppings and other accumulation of components on the surface, very affect the power generation of photovoltaic power station, so regular cleaning of photovoltaic power station solar panels is necessary. According to industry statistics, often cleaning photovoltaic solar panels, can effectively improve the annual power generation of about 8% it.
So, how to clean photovoltaic solar panels? How long to clean a more appropriate? With what tools to clean the best photovoltaic panels? Today, we answer for you one by one.
From the current point of view, the home photovoltaic power station solar panels owners can clean themselves, if there is no special circumstances, 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 very low cost, use are also very convenient.
When cleaning, if there is only a small amount of dust on the surface of the solar panel, just use the high-pressure water gun for a simple rinse.
If the surface has sand, mud and other granular pollutants, 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 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 and clean with glass water, and finally rinse with a water gun.
It should be noted that in the process of using 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?
(1) The best time to choose to clean in the early morning, evening or night, avoid the noon and other high temperature time cleaning, so as not to cause damage to the solar panels.
(2) When cleaning, pay attention to avoid using hard objects, sharp objects directly touching the solar panels.
(3) 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 season, generally cleaning once a month can be (if there is the phenomenon of snow, to clean up in a timely manner), the rest of the month can be cleaned 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 when we wash our hands with soap, there will be a thin layer of film on the hands, the same reason, after cleaning the components with soap, will also leave a film or residue on the surface of the photovoltaic modules, will prompt dust and other faster adhesion and accumulation, affecting the power station power generation. In addition, it is also not advisable to use other corrosive cleaning agents.
