Many models are available to simulate the solar radiation incident on monofacial photovoltaic panels but these models cannot be used to evaluate the radiation incident on a bifacial photovoltaic panel as it does not consider the bifacial gain due to ground reflection and diffuse sky radiation. In this paper an optical model was developed to measure the global solar irradiance on front and rear side of a bifacial photovoltaic module. The bifacial gain at the rear surface is modelled by considering the diffuse sky radiation and reflected component of light from ground and nearby surfaces. An optimised model is developed for Equatorial zone for maximum bifacial gain considering tilt and shading parameters. A comparative study on annual gain for the bifacial module compared to monofacial module also done for the topical latitude zone.
