Unless you live in an area that doesn’t get much rain, or you live in an area with high amounts of smog or dust, cleaning solar panels is not usually necessary. Fine dust or dirt do not have much of an effect on the efficiency of your panels, although this can eventually build up into hard grime that will begin causing problems.. .
One of the best aspects of solar panels is that they are basically maintenance-free; you simply set and forget. However, it’s good to make sure they are not being shaded too much and to. .
Solar panels have no moving parts and are thus basically maintenance-free! They do not need to be serviced at all, other than occasional cleaning.. Look for the green LED: when it is on, the system is producing power, if it is flashing, this means the inverter has AC power and is in Standby mode. [pdf]
