Construction And Monitoring Of The Unique Roof Photovoltaic System In Prague

A photovoltaic system with a nominal output power of 449 kW(p) has been working reliably for almost 9 years on the roof of a sports stadium in Prague. We have used the monitoring system Solarmon-2.0 developed by us to monitor the data. A roof-mounted structure (RIPV) with flexible photovoltaic modules based on thin layers of amorphous silicon was chosen. These modules are located horizontally and lie flat over the roof so that they can not be seen from the street and do not interfere with the architectural concept of the city district. In this article we describe the unique design of the photovoltaic system and we present interesting results captured from the evaluated data. In the end, we discuss the comparison of the amount of electricity produced with the expected values in the given location and comparison of the data with similar photovoltaic systems.
