Humans have been accustomed to burning fossil fuels to generate energy for a long time. It has become an alarming problem that the climate is changing day by day and the demand for fossil fuels is increasing. The burning of coal, oil and other fossil fuels is used to produce electricity, but this pollutes two vital elements such as air and water in our environment. Say no to plagiarism.

With a population of 163 million, Bangladesh is one of the most densely populated countries. Rapid urbanization fueled by stable economic growth has created enormous demand for energy. In Bangladesh, electricity comes from burning gas or fuel. The electricity sector in Bangladesh has a national grid with an installed capacity of 15,379 MW as of February 2017. The government of Bangladesh plans to increase power generation and the electricity demand in Bangladesh is expected to reach 34,000 MW by 2030. There is an ambitious target to generate 2,000 MW of electricity from renewable energy by 2021 and of which at least 10% should be achieved from renewable sources, including solar energy system. To this end, the government is currently working to install solar panel-based power projects connected to the national grid, which will have a capacity of 572 MW. Of the 2000 MW of solar energy, 1000 MW would come from the rooftop system. There is an urgent need to employ renewable energy in every possible form and move towards the sustainable energy sector. The photovoltaic system is one of the most important and promising technologies capable of producing electricity to meet the electricity demand of the whole world. Since the last decade, the photovoltaic industry has been growing more than 40% per year due to the decrease in photovoltaic systems. There are two effective systems for designing solar photovoltaic systems. One is a stand-alone system and the other is a grid-connected system. P. Karki et al. perform an analysis for grid-connected PV system in Kathmandu and Berlin using PVsyst software. In the simulation it was found that Kathmandu produces more solar energy than Berlin with the same system. Y. M. Irwan et al. do an analysis study for a 150kW solar system. In the study we found that Cyprus has a high number of sunny days in a year, so the investment in solar system is very effective. Shukla et al. performed the design and analysis of the solar photovoltaic system on the roof of the hostel building at MANIT and determined the payback period to be 8.2 years. Raturi et al. studied the grid-connected photovoltaic system for Pacific island countries in the case study of the 45 kWp GCPV system located at the University of the South Pacific (USP) marine campus in Fiji. Furthermore, Dawn et al. showcased India's recent developments in the solar sector. Matiyali et al. evaluated the performance of a proposed 400 KW grid-connected solar PV system in Dhalipur. The performance ratio and different types of power losses were calculated. The obtained performance ratio value was 78.1% from the results where the practicality of solar photovoltaic system was discussed. Please note: this is just an example.
