A study published in June in the journal Environmental Science & Technology Letters attempted to quantify the impact of and pollution and dust on the performance of solar energy production.


Researchers from Duke University collected data from solar panels in India and found that efficiency increased by 50% when the panels were cleaned after several weeks of dust accumulation.


Founded in 2013, Eccoppia offers its dust-removal robots to utility-scale solar farms, using data collected in the process in order to optimize performance. It lists as clients power utilities including France’s Engie S.A., NTPC Ltd. of India, and U.S.-based renewable energy company SunEdison Inc.


“The financial stability this investment grants us will enable the company to continue serving the largest energy players in the world, meeting the requirement of the top financial institutions involved in cleantech, and the growing demand in our pipeline,” Eccopia co-founder and CEO Eran Meller said in a statement.
