Beskrivning av examensarbetet
Agrivoltaic systems are photovoltaic systems that combine electricity production and farm activities. As compared to ground-based photovoltaic systems, agrivoltaic systems present several advantages: higher electricity yield, crop yield and water savings as compared to common practices. The combination of revenues can lead to high land use efficiency and shorter payback time. The first agrivoltaic system installed in Sweden consists of 3 rows of vertically mounted bifacial PV modules facing west/east. Bifacial modules are nowadays more accessible and with multiple benefits compared to monofacial modules as they can receive solar irradiance on both faces of the solar panel, hence increasing the power output.
Modelling and simulation of the performance of a bifacial model is a complex task due to an increase in the number of factors to be considered that for monofacial modules are not significant enough. This thesis aims at studying the current available bifacial photovoltaic modelling techniques, specially view factor approaches OptiCE bifacial model, NREL SAM, PVSYST and ray-tracing models Radiance and provide a comprehensive comparison of the benefits and drawbacks of each technique with performance simulation of existent site measurements if possible, from the agrivoltaic system installed in Kärrbo to find which technique has better accuracy.
It can be adapted for 15HP and 30 HP.
