INTRODUCTION Men have been habituated to burn fossil fuels to generate energy from long time ago It has become an alarming problem that climate has been changed day by day due to increasing use of the fossil fuels Burning coal petroleum and other fossil fuels is used to produce electricity but which pollutes two vital elements like air and water in our environment Renewal energy is alternating source to produce energy and it do not any bad impact to environment and keep safe of our environment With a population of 166 37 million Bangladesh is a one of the most densely populated country a Rapid urbanization fueled by stable economic growth has created a huge demand of energy In Bangladesh the electricity comes from burning gas or fuel The utility electricity sector in Bangladesh has one National Grid with an installed capacity of 15 379 MW as on February 2017 b The Government of Bangladesh has planned to increase power generation and the demand for electricity in Bangladesh is projected to reach 34 000 MW by 2030 There is an ambitious target to generate 2000 MW of renewable energy electricity by 2021 and whose at least 10 would be met from renewable sources including solar power system c For this purpose the government is currently working to install solar panel based power projects connected with the national grid which will have a 572 MW capacity d From the statistics of solar system use in the country we assume that 1000 MW energy might be come from solar system to meet the 2000 MW renewable energy target
There is an urgent need to employ renewable energy in every possible form and move toward the sustainable energy sector Photovoltaic system is one of the most important and promising technology that are able to produce the electricity to meet the electricity demand of the whole world e Since last decade the photovoltaic industry grows more than 40 per year due to decrease in cost of PV system f There are two effective systems for solar photovoltaic plant design One is stand alone system and other is grid connected system Karki et al have done an analysis for grid connected PV system in Kathmandu and Berlin by using PVsyst software g In the simulation it is found that Kathmandu is able to produce more solar energy than Berlin with the same system Irwan et al have done a study to analyze for a 150kW solar power plant h In the study it found that Cyprus has a high number of sunny days in a year so investment of the solar plant is very effective Shukla et al i performed the design and analysis of rooftop solar PV system for Hostel building at MANIT and determined the payback period of 8 2 years
Raturi et al j studied the grid connected PV system for Pacific island countries in case study of 45 kWp GCPV system located at the University of the South Pacific USP marine campus in Fiji Further Dawn et al k showed the recent developments of India in the solar sector Matiyali et al l evaluated the performance of a proposed 400 KW grid connected solar PV plant at Dhalipur and they calculated server types of power loss and performance ratio of the PV system Value of the performance ratio obtained was 78 1 from the results practicality of the solar photovoltaic power plant was discussed From literature review we found that PVsyst software is one of the best software for simulation of sizing optimizing loss analysis and financial analyses of a grid connected photovoltaic system m In this paper we calculated financial analyses and did a simulation with PVsyst V6 43 software Proper sizing and calculation of grid connected PV system is done for the administrative building of Hajee Mohammad Danesh Science Technology University Dinajpur Bangladesh In most of the previous research studies we found that research has mainly been done in sizing and optimizing of solar systems but cost analysis is not carried out Thus this research is aimed at fulfilling the research gap which is missing in previous studies
