Boosting Profitability: the Power of Vertical Bifacial PV in Modern Agrivoltaics

This study investigates the potential of fixed tilt vertical bifacial (VB) photovoltaic (PV) systems in agrivoltaics (APV), focusing on their economic viability rather than its agricultural benefits. Unlike traditional PV installations, vertical bifacial systems allow for more uniform light and rainwater distribution to crops and offer protection against strong winds. Moreover, this work states the profitability and grid integration of these systems, demonstrating energy production profiles of vertical bifacial APV in Germany. In contrast to the state of technology of south-tilted PV, vertical systems can mitigate negative midday electricity prices, making them a promising alternative for the future energy market. Simulation results comparing the Huasun/Next2Sun SHJ modules to traditional TOPCon and PERC modules indicate a significant energy yield advantage in the vertical bifacial system, if driven by precise module selection and racking system design. The production profile of the Next2Sun system in Wellingen, Germany, shows two production peaks, with minimal self-shading effects and high bifaciality. Additionally, financial analysis of vertical bifacial PV plants in Donaueschingen/Aasen and Dirmingen reveals up to 45% surplus performance over the market price, highlighting the economic potential of these systems in the context of increasing PV capacity and negative midday electricity prices. This work suggests that vertical bifacial PV installations can be a profitable and sustainable solution for integrating renewable energy into the agricultural sector.
