Grid-connected Rooftop Solar PV System in the Bangladesh Residential Area of Government Primary School

Abstract

Our Bangladesh is one of the most densely populated areas in south-east Asia. One of the major problem of our agriculture dependent Bangladesh is the shortage of electricity generation. Due to the lack of electrical energy, that is why load shedding is the common issue of our country. But electrical energy is so much important for develop living standard. Renewable energy is the best way to solve the problem and increasing power generation. For this reason solar cell can be a potential initiative that can greatly reduce the power shortage in our country. This thesis book basically highlight on-grid solar system in government primary school`s rooftop. Here is all the strategic information for the implementation of a project of 9.9 KW. The simulation section we are used PV syst software and we were run the software. This planned system of ours will meet all the needs of the school and the excess electricity will go to the grid. Full energy directly will be exported to the 3-phase AC line. We just select Dhaka, Gazipur city corporation area for experiment the simulation. This is total system power is 9.9 KWp. The software show that total cost will be $7852.49 USD that means 659610 taka. PV syst results are, production from the system is about 15888 kWh/year. Normalized production is 4.40 kWh/kWp/day. Finally cost of produced energy is $0.031 USD per unit that means 2.6 taka per unit. Most important matter is payback period is approximately 7.3 years. . If the roofs of all government primary schools in Bangladesh can be converted by the on-grid solar system field, then the country will be able to meet a huge amount lack of electrical energy by sending additional electrical energy to the grid with full-fill demand for all of government primary schools. PV systems are now available for easy installation with all necessary accessories in a competitive market of Bangladesh. Day by day people going on interested to install the PV system in our country. PV system offer enormous benefits to countries with a good solar resource and could be deployed much faster than the current rate. Finally we want to say that it can will be a great solution for our country and economy system.
