Why the solar panels must be cleaned?
Solar panels are made from a variety of materials, some of which are quite sensitive. Cleaning solar panels is as essential as the installation process. When these materials are not cleaned properly, they can cause corrosion and begin to damage the panel. It is essential to clean solar panels, carefully, to avoid damage.
​
Many solar panel owners overlook the importance of regular panel cleaning. If you don't do this frequently enough, the layer of dirt on your system will reduce the overall performance of the system, costing you extra money to run each time.
​
Dirt buildup on solar panels can be caused by a variety of things, including lichens, soot, bird droppings, dust particles in the air, sticky tree and plant sap.
​
Rain is not enough to remove this layer, it can even make the situation worse. Because of the air pollution we encounter in some parts of the country, the rain is not clean, which can be seen on your car as soon as the rain stops. Imagine how affected your panels are!

What major manufactures say?
Trina Solar, one of the market's top producers of solar panels, emphasizes the need of frequent cleaning of its panels in its user handbook: "The amount of electricity generated by a solar module is proportional to the amount of light falling on it. A module with shaded cells will produce less energy and therefore it is important to keep the module clean."
In their frequently asked questions, Panasonic, major global manufacturer of solar photovoltaics advise to wash dust and dirt off your solar panels more than twice per year.
Some of Panasonics limited warranty exclusions are; "Inadaquate maintenance", "damage or corrosion resulting from environmental pollution such as soot and mold".
