Abstract
This study presents the design, modeling, and performance evaluation of a grid-connected
bifacial photovoltaic (PV) system for Effat University in Jeddah, Saudi Arabia. The objective
is to assess whether bifacial solar technology, combined with single-axis horizontal tracking,
can outperform traditional monofacial systems in high-irradiance environments. The
proposed 24.64 kWp system was designed within a 286.31 m² open-area site, utilizing Jinko
440 W bifacial modules mounted on horizontal single-axis trackers to maximize exposure to
both direct and reflected irradiance.
Performance simulations were conducted using PVsyst v8.0.15 and Helioscope,
incorporating real meteorological inputs, ground-albedo effects, temperature variations, and
soiling losses. The system demonstrated an annual energy yield of 57,398 kWh, a specific
production of 2,329 kWh/kWp, and a performance ratio of 79.36%. These results confirm
that bifacial modules provide a significant enhancement in energy generation, driven
primarily by rear-side irradiance gains and improved sun-tracking geometry.
The analysis also highlights the primary factors influencing system performance, including
high ambient temperatures and dust accumulation, both characteristic of desert climates.
Overall, the findings demonstrate that bifacial PV systems with single-axis tracking represent
an efficient and practical solution for campus-scale renewable energy deployment in Saudi
Arabia, supporting Effat University’s sustainability objectives and contributing to the
national clean-energy targets outlined in Vision 2030.
