Experimental Comparison of Planar and Parabolic Reflectors for Improved Photovoltaic Output

Abstract

The global demand for renewable energy sources has propelled advancements in photovoltaic (PV) technology, aiming to enhance the efficiency and cost-effectiveness of solar power generation. This study empirically examines how reflector geometry affects photovoltaic (PV) system performance by contrasting flat and parabolic reflector designs. The two reflector types were tested in a controlled outdoor area with the same ambient factors and solar irradiation. Over 30 days, important performance indicators such as power output, current-voltage characteristics, and temperature impacts were measured. Because parabolic reflectors are better at concentrating diffuse and directing sunlight, the results show that they can increase PV output by up to 28% compared to planar reflectors. Planar reflectors, on the other hand, showed less vulnerability to hotspot development and more uniformity in light distribution. The results provide useful insights for developing reflector-integrated PV systems in a variety of climatic settings by highlighting the trade-offs between operational stability and efficiency benefits.
