A New Model for Estimation of Energy Extraction from Bifacial Photovoltaic Modules

The energy yield from bifacial solar photovoltaic (PV) systems can be enhanced by optimizing the tilt angle. Bifacial modules boost 4% to 15% depending on module type and ground reflectivity with an average of 9%. selection angle depends several factors, including geographical location, weather variation, etc. Compared variable angle, a constant is preferred point view cost installation maintenance. This paper proposes new method for analysing modules. A simpler rear-side irradiance model presented estimate module. detailed analysis also explores optimum inclined south–north orientation obtain maximum possible Taking four regions into account, i.e., Kharagpur, Ahmedabad, Delhi, Thiruvananthapuram, in Indian climate, we studied cases. Kharagpur system showed monthly rear gain 13%, Delhi climate performance ratio 19.5%. We impact albedo GCR Finally, estimated was validated PVSyst version 6.7.6 as well real field test measurements taken National Renewable Energy Laboratory (NREL) located USA.
