The article describes the construction of the photovoltaic (PV) system and shows the unique data measured during the solar eclipse on the 20th of March 2015. The data are discussed. The PV power plant was installed on the roof of the football stadium in the year 2010. Considering the location on the atypical roof and integration into the architectural style of the surroundings, flexible photovoltaic foils based on thin semiconducting layers of amorphous silicon oriented horizontally were used at this location. Some data obtained during five-year operation and testing of the PV power plant are also presented. (C) 2016 Elsevier Ltd. All rights reserved.
