Airtouch Solar developed a solution for utility-scale photovoltaic panel cleaning. Airtouch Solar's solution is an autonomous water-less cleaning robot that removes heavy soiling particles. Airtouch utilizes microfiber wipes and wind-blowing technology with the aim of improving cleaning results. Airtouch's dedicated control system enables the robot to move smoothly along the panel, sensing changes in movement and outdoor condition as well as any loose screws. Together with the company's deep-learning software, the company can predict problems in advance and reduce failure rate. A sub-giga long-range communication system is embedded in each robot, allowing the robots to communicate freely with the center up to one kilometer away. This helps eliminate the need for high communication towers and helps prevent miscommunication in harsh weather conditions.
