Solar energy, as a clean and renewable source, plays a crucial role in reducing GHG emissions. However, sustainable utilization of solar power relies on maintaining the solar panels. Traditional cleaning methods consume a substantial amount of water. To protect solar panels and minimize water waste, Ecoppia’s fully autonomous robotic cleaning solutions utilize soft microfibers and controlled airflow. The cleaning system is energy independent, requiring no external power source and drawing power from its own on-board batteries that are charged via each robot’s dedicated solar panels. Independent testing by the PI Berlin Institute found no power degradation or change in electroluminescence of solar panels after 20+ years of daily cleaning by Ecoppia E4 robots. Moreover, Ecoppia’s water-free solution has thus far saved 6.4 billion liters of water.
