Men have been used to burning
fossil fuels to generate energy from long time ago. It has become an alarming
problem that climate has been changed day by day and the demand of the fossil
fuels is increased. 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 163 million,
Bangladesh is a one of the most densely populated country. 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 1. The Government
of Bangladesh has plans 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 2. 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 3. Out of
2000 MW solar energy, 1000 MW would be come from rooftop system. 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 premising technology that are able to
produce the electricity to meet the electricity demand of the whole world 4.
Since last decade, the photovoltaic industry grows more than 40% per year due
to decrease in PV system 5. There are two effective systems for solar
photovoltaic plant design. One is stand-alone system and other is grid
connected system. P. Karki et al. 6 do an analysis for grid connected PV
system in Kathmandu and Berlin by the use of PVsyst software. In the simulation
it was founded that Kathmandu is more solar energy produced than Berlin with
the same system. Y.M Irwan et al. 7 do a study to analysis for a 150kW solar
power plant. In the study we 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.8
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. 9
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. 10 showed the recent developments
of India in the solar sector. Matiyali
et al. 11 evaluated the performance of a proposed 400 KW grid connected solar
PV plant at Dhalipur. Performance ratio and several types of power losses were
calculated. 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 the
best software for simulation of sizing, optimizing, loss analysis and financial
analyses of a grid connected photovoltaic system 12. In this paper we calculate
financial analyses and simulation with PVsyst V 6.43 software. Proper sizing and calculation of grid connected PV
system is done for Hajee Mohammad Danesh Science & Technology University,
Dinajpur, Bangladesh. This research is aimed at fulfill the research gap which
is missing previous. This research work is carried out to address the gap in
the research and propose sustainable HSTU campus through a case study.
