MSCA IF Fellow

Dr. Leonardo Micheli is a MSCA IF Fellow at the University of Jaen, in Spain. He is currently working on developing a smart algorithm for the prediction of future soiling losses based on current and historical meteorological data. If successful, this method will allow to optimize the cleaning schedule of PV systems, limiting the O&M costs and increasing the energy yield of the system. During the previous three years, Leonardo has been working within the PV Performance and Reliability Group at the National Renewable Energy Laboratory (NREL) on the U.S. Department of Energy-funded “Addressing Soiling: From Interface Chemistry to Practicality” project. At NREL, he investigated different methods to predict soiling losses using PV performance data or environmental parameters, presenting also a work on the seasonality of soiling. He was involved in the effort to develop a standard on the abrasion due to soiling and cleaning. Leonardo received a PhD in Renewable Energy from the University of Exeter (UK) in 2015, with a thesis on the concentrator photovoltaics
