The main focus of this paper is to present the current prospects, potentials, research activities, future concerns, and applications of solar photovoltaic (PV) systems in Bangladesh. Despite the existence of several articles in the literature on solar energy prospects in Bangladesh, the diffusion of several solar PV applications throughout the country, their rapid progress analysis, and existing feasibility study outcome analysis are still unrevealed. Therefore, an endeavour has been made for the first time to condense the government and non-government contributions to disseminating solar energy throughout the country. Twenty-one feasibility studies at different locations of Bangladesh are reviewed and analysed, in terms of financial viability, sensitivity analysis, and greenhouse gas emissions, to foresee the prospects of solar energy in Bangladesh. Sensitivity analyses are performed, with six sensitivity variables, which reveal that the total net present cost of the solar project implementation may be increased by 20% (maximum) in the lowest solar potential area than the highest one with an average payback period of 13 years. This paper also identifies the policy gaps, classifies the barriers into eight categories, and discusses the conceivable approaches to defeat those barriers, followed by recommendations in six different aspects.
INTRODUCTIONElectricity is an essential prerequisite for the sustainable advancement and modern progress of the world [1]. Its utilisation is expanding worldwide with the pace of technological development and quick urbanisation. The global primary energy consumption increases to 13,946.2 million tonnes of oil equivalent (Mtoe) in 2019 from the energy consumption of 11,531.96 Mtoe in 2009, which shows a rapid increment in the demand during the gap of 10 years [2]. Oil represents the most noteworthy contribution of 33.1%, followed by coal (27%) and natural gas (24.2%) among the available energy resources [2]. International Energy Agency (IEA) [3] expected that the supplies of coal, oil, and natural gas would be depleted by 122, 42, and 60 years, individually [4]. Therefore, there is a global need to search for alternative energy sources. It is anticipated that from the year 2011 to 2030, the worldwide essential energy utilisation will increase by 36% with aThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.
