One of the challenges of solar power is keeping the panels clean, because dust and dirt drastically reduce your energy efficiency. This is particularly difficult to achieve in large solar parks, and especially those in the desert, where there is little water.

Israeli society Ecopia solved this problem with a smart robot that cleans solar panels every day, which increases the efficiency of solar panels by up to 35%. This week the solar park Kibbutz Ketura He was the first to install Eccopia robots, making it the world’s first self-cleaning photovoltaic park.

the robot increases the efficiency of solar panels

Every night while the world is sleeping 100 robots will work in Ketura Park to clean its solar panels, so that the next day they can better enjoy the sun’s rays.

Each robot uses multiple microfiber cloths and controlled airflow to gently clean the panels without the need for water. Each robot can clean around 100 m2 of panels per minute. Before, Ketura’s solar panels were only cleaned 9 times a year because it took 5 days with a lot of work and expense.

The robots are remotely controlled and operate simultaneously, starting and ending at the same time. Even better, They are energy independent, as they are self-sufficient with their own solar panels.
