Men have been habituated to burnfossil fuels to generate energy from long time ago. It has become an alarmingproblem that climate has been changed day by day due to increasing use of thefossil fuels. Burning coal, petroleum and other fossil fuelsis used to produce electricity, but which pollutes two vital elements like airand water in our environment.  Renewalenergy is alternating source to produce energy and it do not any bad impact toenvironment and keep safe of our environment. With a population of 163 million,Bangladesh is a one of the most densely populated country. Rapid urbanization fueled bystable economic growth has created a huge demand of energy. In Bangladesh, theelectricity comes from burning gas or fuel.

Theutility electricity sector in Bangladesh has one National Grid with aninstalled capacity of 15,379 MW as on February’ 2017 1. The Governmentof Bangladesh has planned to increase power generation and the demand forelectricity in Bangladesh is projected to reach 34,000 MW by 2030.There is anambitious target to generate 2000 MW of renewable energy electricity by 2021 andwhose at least 10% would be met from renewable sources including solar powersystem 2. For this purpose, the government is currently working to installsolar panel-based power projects connected with the national grid, which willhave a 572 MW capacity 3.

From the statistics of solar system use in thecountry we assume that 1000 MW energy might be come from solar system to meetthe 2000 MW renewable energy target. There is an urgent need to employrenewable energy in every possible form and move toward the sustainable energysector. Photovoltaic system isone of the most important and premising technology that are able to produce theelectricity to meet the electricity demand of the whole world 4. Since lastdecade, the photovoltaic industry grows more than 40% per year due to decreasein cost of PV system 5. There are two effective systems for solarphotovoltaic plant design.

One is stand-alone system and other is gridconnected system. Karki et al. have done an analysis for grid connected PVsystem in Kathmandu and Berlin by using PVsyst software 6. In the simulationit is found that Kathmandu is able to produce more solar energy than Berlinwith the same system.

Irwan et al. 7 have done a study to analyze for a 150kWsolar power plant. In the study we found that Cyprus has a high number of sunnydays in a year so investment of the solar plant is very effective.

Shukla etal. 8 performed the design and analysis of rooftop solar PV system for Hostelbuilding at MANIT, and determined the payback period of 8.2 years. Raturi etal. 9 studied the grid connected PV system for Pacific island countries incase study of 45 kWp GCPV system located at the University of the South Pacific(USP) marine campus in Fiji. Further, Dawn et al.

10 showed the recentdevelopments of India in the solar sector. Matiyali et al. 11 evaluated the performance of aproposed 400 KW grid connected solar PV plant at Dhalipur. Performance ratioand several types of power losses were calculated.

Value of the performanceratio obtained was 78.1% from the results practicality of the solarphotovoltaic power plant was discussed.  From literature review, we found that PVsyst software is oneof the best software for simulation of sizing, optimizing, loss analysis andfinancial analyses of a grid connected photovoltaic system 12. In thispaper we calculated financial analyses and did a simulation with PVsyst V6.43 software. Proper sizing and calculation of grid connected PVsystem is done for the administrative building of Hajee Mohammad Danesh Science& Technology University, Dinajpur, Bangladesh.

In most of the previousresearch studies, we found that research has mainly been done in sizing andoptimizing of solar systems but cost analysis is not carried out. Thus this researchis aimed at fulfilling the research gap which is missing in previous studies.
