There are about 243 marine tanker vessels operate in Bangladesh, and they might serve as an effective location for solar photovoltaic (PV) plants, where solar energy would be the most suited renewable energy to replace the fossil fuel used in the ships. Such PV on maritime vessels does not need land mass, as landmass is a scarce resource in Bangladesh, and is thought to boost efficiency. The quantified vessel navigates between Bangladesh-India, Bangladesh-Malyasia, Bangladesh-Singapore, Bangladesh-Indonesia, Bangladesh-Mumbai, Bangladesh-Sri Lanka. In this paper, a novel approach to the PV array on marine vessel is presented and realistic calculation of energy output is carried out of the planned PV system. Finally calculated the realistic CO2 emission reduction by using this approach for a sustainable future. Applying “globalsolaratlas” software (for horizon and sun’s path estimation); HOMER Pro, PVsyst 7.2, and NREL’s PVWatt calculator (for solar radiation calculation); shiptraffic (for vessels path analysis), vesselfinder (for number of vessels analysis); this research suggests that marine vessels are one of the best places to construct a proposed “tree-shaped solar PV tower” power plant. Estimation reveals that about 35.64 GW of electricity can be generated annually by 181 tanker vessels and will save approximately 9,357.21 tons of CO2 gas emissions annually to the environment when fossil fuel-based power plant for electricity is used.
