This paper presents an easy and accurate procedure of the modeling of a commercially available Photovoltaic Panel by using Solar Module (Physical Model) Simulator embedded in a very powerful Simulation software known as PSIM. Methods of Photovoltaic Panel modeling including mathematical modeling and software based modeling are also discussed in this paper. Apart from modeling types, I-V (Current-Voltage) and P-V (Power-Voltage) Characteristics and some other useful results obtained from PSIM Simulation are further evaluated and compared with the laboratory test results. Limitations of PSIM Solar Module (Physical Model) are also discussed in this paper.

Developing countries like Pakistan, Bangladesh, and Nigeria etc. are facing severe energy and economic crises. The use and awareness of renewable energy system is strongly recommended for economic evolution of these countries. Moreover, they are also facing the problem of dreadful shortage of natural fuel (petrol, diesel and CNG). In order to combat this, our aim is to design a vehicle that could make efficient use of renewable energy source e.g. (the solar energy) as a replacement of natural fuels. Through our model, we have tried to depict the scenario relating to the feasibility of this vehicle on small commercial level, extracting power from solar panel, replacement of IC engine by dc motor, control of motor via dc drive and various other supporting features have been added as the part of this vehicle which can be considered as cost effective (manufacturing). Our experimental work also shows that the large scale commercial production of solar vehicle in developing countries will overcome some part of energy and economic distress because it decreases the dependence on natural fuel due to effective utilization of renewable energy resources, saving environment from pollution and low running cost which could be considered as a great revolution in transport system.
