摘要

Deploying vertical bifacial PV modules can play a significant role in agrivoltaics, fencing walls, noise barriers, building integrated photovoltaics (BIPV), solar PV for electric vehicles, and many other applications. This research work presents the energy yield measurement and simulation of vertical bifacial photovoltaic (VBPV) modules facing East–West (E-W) and South-North (S–N) directions. Also, the VBPV modules are compared with vertical and tilted south-facing monofacial PV modules installed on the rooftop of IIT Bhilai academic building, Raipur (21.16° N, 81.65° E), India. From a series of experiments, 19 days of data were collected over the one-year period from May 2022 to April 2023, with specific inclusion of important days like solstices and equinoxes. The results show that the E-W facing VBPV module gives two production peaks, one in the morning and another in the evening, as compared to the single notable rise at midday observed for a monofacial module. It has been observed that energy generation by E-W facing VBPV module is 0.91 times of S–N facing VBPV, and 1.02 times more than south-facing vertical monofacial module during the studied time frame of 07:15 AM—04:45 PM. This study also presents the generation profiles of E–W and S–N VBPV modules, and compares them with monofacial PV modules for an experimental site located in the central-eastern region of India. Measured energy generation results are compared with PVsyst simulations, while also addressing the limitations of the PVsyst simulation of vertical PV modules.
