What are the precautions for cleaning solar panels?
(1) It is best to choose cleaning time in the early morning, evening or night, avoiding high temperature periods such as noon to avoid damage to the solar panels.
(2) When cleaning, be careful to avoid using hard or sharp objects that come into direct contact with the solar panel.
(3) Do not step on solar panels, brackets, and other components as they may damage the power station and affect its service life.
How long does it take to clean solar panels?
According to industry experience, in seasons with more rain and snow, such as winter, cleaning once a month is generally sufficient (if there is snow accumulation, it should be cleaned in a timely manner), and cleaning twice a month in other months is sufficient.
In areas with strong winds and heavy dust such as the northwest, it depends on the specific situation.
Attention: When cleaning photovoltaic modules, try not to use soapy water as it will leave a thin film or residue on the surface of the photovoltaic module, which will promote the faster adhesion and accumulation of dust and other substances, affecting the power generation of the power station.
In addition, other corrosive cleaning agents should not be used.
Cleaning tools and methods for solar panels
Common tools include high-pressure water guns, soft bristled brushes, cotton mops, etc. These tools are low-cost and easy to use.
(1) When cleaning, if there is only a small amount of dust on the surface of the solar panel, simply rinse it with a high-pressure water gun.
(2) If there are granular pollutants such as sand and mud on the surface, you can first use a high-pressure water gun to wash away the particles, and then use a soft bristled brush to scrub to avoid particles sticking to the photovoltaic modules.
(3) If there are sticky pollutants such as bird droppings and oily pollutants on the surface, use a clean cloth to wipe them off, and clean them with glass water. Finally, rinse with a water gun.
Attention: When using a high-pressure water gun, pay attention to the pressure of the high-pressure water gun. Excessive water pressure may cause damage to the solar panel.
