Ecoppia has announced that its commercially-deployed E4 robotic cleaning system has now cleaned over one million panels.

Soiling - the accumulation of dirt and dust on photovoltaic solar panel surfaces - is one of the greatest impediments to solar energy production efficiency, and can reduce solar panel energy output by up to 35%.

Ecoppia - the only market player deployed at this scale - presents a paradigm shift; a move away from existing labor-intensive, water-based, high-risk panel cleaning solutions.

The autonomous energy-independent water-free E4 robots use a soft microfiber and controlled air flow cleaning system to remove 99% of dust daily, keeping panels at optimal production 24/7/365.

"We are proud to have reached this important milestone, as planned, while continuing to exceed customer expectations for reliability and cost-effectiveness," said Eran Meller, Ecoppia CEO. "We are on track to meet and exceed our expansion plans, such that Ecoppia robots will be cleaning 5 million panels a month by the end of the year, while adhering to the highest standards of operational excellence and customer satisfaction," he concluded
