Experimental Investigation of 4E Performance of A Vertical Bifacial Solar Module During Summer and Winter

Abstract The proposed research work presents the performance analysis of vertically mounted bifacial module (VBFM) with and without tracking during summer and winter season. Also various parameters like Energy Efficiency, Electrical Efficiency, Electrical Exergy, Thermal Exergy, Exergy Efficiency, Environmental analysis, Economic analysis, Exergo-Economic analysis, Enviro-Economic analysis and Exergo-Enviro-Economic analysis of VBFM were studied and presented. The comparative analysis was carried out between two Bifacial solar modules installed in two different orientations (East-West and South – North). The experiments were conducted in the real climatic condition of Minjur, Tamilnadu, India. Under the summer and winter climatic condition, when the life time period of 10, 15 and 20 years are considered higher Energy production factor and higher Life cycle conversion efficiency was obtained from VBFM-EW with tracking during summer and VBFM-SN module without tracking during winter season. Exergetic cost was calculated by considering 15, 20, 25 and 30 years of the system with 2 %, 5% and 10% Interest rate. The maximum exergetic cost was obtained from 30 years of the system under 2 % Interest rate. The Enviro-economic and Exergo-Enviro-Economic analysis provides the carbon credits earned from E-W module was maximum with Rs. 11036.18 during summer season & Rs. 12413.48 from VBFM-SN module during winter season considering the life of the system as 15 years.
