PV modules generate the largest amount of electricity when directly exposed to the sun. In theory, using two-axis trackers would maximize the yield. For obvious economic reasons, a fixed installation towards the south is the more popular setup. But it is not the power output alone, that counts in the end, as power prices differ a lot throughout the day. They are low at noon, when there is plenty of energy available and higher in the morning and evening hours.
That is the question investigated by Matteo Baricchio and Hesan Ziar, two young researchers at the Technical University of Delft. In this episode of OTT CAST, we elaborate on their exciting research work, that compares East/West (E/W) vertical bifacial photovoltaic (PV) modules with conventional North/South (N/S) tilted configuration depending on the design choices – such as distance between module rows and installation height – and external conditions. We are joined by Marc Korevaar, our experienced Scientist at Kipp & Zonen, who supported the researchers during their complex simulations with real measurement data.
