Techno-Economic Analysis of Integrating Residential PV Systems into Dhaka's Power Grid

다국어 초록 (Multilingual Abstract)

The abstract for the thesis “Techno-Economic Analysis of Integrating Residential PV Systems into Dhaka’s Power Grid” summaries the main goals, methods, and findings by looking at both the technical and economic aspects of Bangladesh’s move toward renewable energy. This study closely examines how the 2018 Net Metering Guidelines have influenced the use of residential rooftop solar (PV) systems in Dhaka’s power network. Using data from Dhaka Electric Supply Company Limited (DESCO) in Eastern Housing, Pallabi, Mirpur, the research assesses system performance by applying Life Cycle Cost (LCC) and Discounted Cash Flow (DCF) analysis over 25 years. It explores four practical installation options: rooftop, south-facing, east-facing, and west-facing. The analysis combines models of solar power generation with financial tools like Net Present Value (NPV), Savings-to-Investment Ratio (SIR), and Break-Even Period (BEP) to determine which setups are technically feasible and financially worthwhile. Research shows that solar panels work best when they are installed on south-facing roofs and have an average net present value of USD 2.7 million, a savings-to-investment ratio of 2.6, and a payback period of eight years. So, they are a smart and cost-effective choice. But unless the government gives more money or help, panels that face east or west usually don't make as much money. Bangladesh also wants to lower carbon emissions by installing solar panels on roofs. This does this by lowering demand during peak hours, making energy security better, and making the grid less important. The report suggests changes like updating power rates, making financing options more flexible, standardising metering systems, and encouraging better cooperation between institutions. This study helps guide renewable energy planning in Bangladesh by showing how rooftop solar can help make the city's energy use more sustainable.
