Type: article
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 studyempirically examines how reflector geometry affects photovoltaic (PV) system performance by contrasting flatand parabolic reflector designs. The two reflector types were tested in a controlled outdoor area with the sameambient 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 betterat 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 hotspotdevelopment and more uniformity in light distribution. The results provide useful insights for developingreflector-integrated PV systems in a variety of climatic settings by highlighting the trade-offs betweenoperational stability and efficiency benefits.
