Bangladesh, as a populous South Asian nation, grapples with the dual challenge of meeting escalating energy demands while tackling environmental degradation and reducing dependency on fossil fuels. In response to the imperative of sustainable development and the pressing global issue of climate change, the adoption of renewable energy sources has emerged as a critical strategy. This paper explores the viability and potential of solar photovoltaic (PV) power plants as a solution to Bangladesh’s energy challenges, with a specific focus on the Patenga region.Situated advantageously for solar energy harnessing, Patenga offers a promising locale for solar PV power generation. Through the establishment of a 40 MW solar PV power plant, this study proposes to address the energy requirements of the South Patenga City Corporation High School while also contributing surplus energy to the national grid. The geographic coordinates of Patenga (latitude: 22.235128°N, longitude: 91.806085°E) along the Bay of Bengal present an ideal coastal setting for solar energy exploitation.Detailed analysis reveals the economic viability and environmental benefits of the proposed solar PV project. With a projected payback period of seven years and an estimated revenue exceeding Tk 9 billion, the project promises profitability and sustainability. Leveraging solar energy not only ensures a stable and cost-effective electricity supply for the school but also aligns with the United Nations Sustainable Development Goals (SDGs), particularly in advancing industry, innovation, infrastructure, decent work, and economic growth.The feasibility study conducted through platforms such as the Global Solar Atlas, PVGIS, and PVsyst underscores the viability of solar PV power generation in Patenga. Utilizing advanced software tools, including PVGIS for optimization, the project design aims for maximum efficiency and reliability. By harnessing solar energy, the school endeavors to reduce its carbon footprint, promote green energy adoption, and contribute to climate change mitigation efforts.
