The cleaning frequency of a photovoltaic system cannot be summed up in a universal rule: it depends on many factors specific to your site and environment. Climatic conditions play a major role: rain, humidity, dew, wind, and temperature directly influence the accumulation of dust and dirt on your panels.
The nature of the dirt is also decisive. Sand, dust, pollen, bird droppings, industrial or agricultural emissions, lichens, and mosses can accumulate at very different rates depending on the region and the season. Finally, the very architecture of your installation—panel layout, tilt, module type, and whether or not a frame is present—impacts the speed at which the surface becomes dirty.
In some regions, photovoltaic installations require between 10 and 25 cleaning cycles per year (e.g., India), while others require only 2 to 5 operations (e.g., the United States), with intermediate variations, such as in Mexico (7 to 15 cycles per year).
This is where AX Solar cleaning robots come in, capable of offering a personalized approach for each installation. Thanks to their intelligent systems, they can adapt the cleaning frequency and method based on the actual soiling of the panels, ensuring both optimal energy efficiency and module preservation for several decades.
Thus, cleaning frequency becomes a tailor-made process, combining efficiency, time savings, and lasting protection for your photovoltaic installation.
