Spatial Analysis of Annual and Seasonal Sunlight Variation through GIS Kriging Techniques

Abstract

Today the developing countries are facing multiple types of crises especially in the term of energy crises. Also Energy has great worth because it is very essential for the development of any society as well as for the adequate standard of living, every country requires the energy i.e. Electricity, as to carry out the basic activities, however as the population is increasing rapidly so the demand of energy (electricity) is also increasing and if the required demand of energy is not supplied then it creates the energy shortage, therefore we require the alternative resources (solar energy), to control the energy crises. Sunlight has a lot of importance because it is the renewable resource and is the best alternative to control the energy crises. Pakistan is a country which is facing the energy crises. These crises take the serious shape of torment in summer season, especially in Sindh province. However due to its geographical location the province receives the enough quantity of sunlight in whole year. In this research our focus is to spot the most appropriate locations for the efficient utilization of solar energy in different seasons, based on pointed data, derived from different meteorological observatories over the last thirty years. And with the help of Geographic information system the annual average sunlight of the province has been observed which is 8.5 hrs /day and the central part of the province is spotted, which is more suitable for solar plants, because the temperature remains high in this part.
