Abstract/Summary:


Photovoltaic (PV) technology has the potential to be integrated on many surfaces in various environments, even on water. Modelling, design and realization of a floating PV system has more challenges that conventional rooftop or free standing PV system. In this work, we introduce two innovative concepts for floating bifacial PV systems, describing their modelling, design, and performance monitoring. The developed concepts are retractable and enable maximum energy production through tracking the Sun. Various floating PV systems (mono facial, bifacial with and without reflectors) with different tilts and tracking capabilities are installed on a Dutch lake and are being monitored. Results of thermal study showed that partially soaking the frame of PV modules into water does not bring a considerable additional yield. Electrical yield investigation concluded that due to low albedo of in land water areas (5%), bifacial PV systems must have reflectors. Modelling result showed that such system can have 18% more annual energy yield compared to a mono facial PV system installed on land.
