<p>Bifacial solar photovoltaic technology has accrued significant attention due to its potential for enhanced energy generation. While rear-side irradiance is a primary determinant of bifacial PV performance, its complex interplay with factors such as tilt angle, albedo, and module orientation remain underexplored. This analysis looks into the effect of tilt angle on the energy output produced by a 440 W bifacial solar module that is fixed to the rooftop of the Technology Tower at the Vellore Institute of Technology in Vellore (12.97° N, 79.16° E), India. The module is subjected to tilt angles ranging from 0° to 90° during sunny days in March 2024, with performance metrics including power output, voltage, current, temperature, irradiance, and fill factor recorded at 30-min intervals. To isolate the influence of rear irradiance and simulate a ground-mounted scenario, a sand-covered ground surface is employed. Sand has been chosen due to its widespread availability, consistent optical properties, and ability to represent a typical ground surface in many regions. In reference to the experimental framework, the photovoltaic module's power generation shows a significant degree of reliability for tilt angles between 13° and 30°, with a 3% measurement uncertainty included. The findings of this investigation show the importance of optimizing tilt angles and improving ground reflectance in order to attain the highest possible energy output from bifacial photovoltaic systems. This research aligns with Sustainable Development Goals (SDGs) 7 (Affordable and Clean Energy) and 13 (Climate Action) by contributing to the development of efficient and sustainable solar energy solutions.</p>
