A Decision Support Technique to Design Solar Power System for Sindh Agriculture University Tandojam

Abstract

Pakistan's energy requirements are increasing day by day and not only economic growth but political stability is linked with the availability of energy resources. At present the total generation installed capacity is 21,000 MW. The peak demand is 15,000 MW, but the production is only 9,000-10,000 MW, resulting in 10-12 hours of load shedding. The root cause of the faulty fuel mix is the use of furnace oil as the main fuel to produce thermal electricity. This energy crisis has destroyed at least 50 percent of the industrial sector that has led to increase in the rate of unemployment. It has badly affected the fixed income group because costs of goods and services have increased. Due to the electricity crises a common man look to the available short term alternatives such as generators and Uninterrupted Power Supply (UPS) units but they are not environmental friendly nor have enough storing capacity to provide continuous energy. Due to above problems, the report has been formulated which divert the attention of the policy makers of Sindh Agriculture University Tandojam for bringing the university to the solar system. This process was done using both software and manual analysis, to determine the tilt angle, azimuth degrees, Photovoltaic module size, size of the inverters, batteries and charge controller. At the other hand we also estimated the cost efficiency of solar power system as compare to HESCO in which we analyze the basic appliances like tube lights, savers, fans and computers. The total load of the all faculties and departments are 3, 51,498 Watts per month and the monthly expenditure are paid by university is Rs.11,59,943. But as compare to solar power system the monthly expenditure for same load is just Rs.2, 68,504 and it has a 25 years life as well. If we compare the HESCO and solar power system we would save approximately 76.8% monthly cost. The result of this study can be referred by the policy makers and decision takers of Government and as well as private sectors. We all are causing the problem of pollution, but we need to realize that there are many other power sources for running appliances, and that these options need to be taken advantages.
