PV Solar System for Rural area in Bangladesh, Engineering and Economical Aspects.

Abstract: The energy demand is increasing very rapidly all over the world. Solar energy is one renewable solution to cover the energy demand. Solar power is a universal green energy source, and we receive from the sun more than ten thousand times energy than it has needed on the earth. This report investigates the electricity generation by using solar PV panels for the given village as well as the transmission systems. The main priority of this report is to calculate the demand electricity of the village, plant design also considering the power losses. Three different scenarios to transmit the generated power to the consumers end were considered and studied. The three different cases and cases are, • Grid connection. • Micro-grid power supply system with full battery storage. • Micro-grid power supply system with partial battery storage. All three system were analyzed based on the technical specifications, power losses during transmission. The all calculation was completed by the help of different software, such as PVGIS, MS excel, different empirical formulas and previous research papers. To complete the calculation this, report also consider a few assumptions. After completing all analysis and calculations, the research outcome was showing that the microgrid power supply system with whole battery backup storage will be the better solution both technically and economically. Photovoltaic (PV) solar cell-based microgrid systems can be one of the most feasible solutions to provide electricity in rural areas. Therefore, this system can play a vital role in Bangladesh to provide electricity in rural areas. In Bangladesh, there are several positive aspects to promote the use of photovoltaics (PV), such as many solar irradiations, low technology and labour cost, and a few subsidies from the government.
