Mechanical arms
This system consists of a brush transported by a vehicle driven by an operator, this system must be equipped with pressure sensors to avoid damage to the solar panels. Given the layout of some solar parks, this system is associated with a high risk of accidents.
Semi automatic
The cleaning system is placed at the end of the panel array and moves automatically. It is necessary to overcome some gaps between panels manually, but in general they are light and easy to maneuver.
Fully automatic
These systems are installed when the park is built, they are generally used in areas that cause daily soiling, where very frequent cleaning is necessary, however they are extremely expensive systems and, as they are always outside, can be subjected to accelerated degradation.
