ABSTRACT

The tilt angle has a major impact on the solar radiation incident on a surface. For a fixed tilt angle, the maximum power over the course of a year is obtained when the tilt angle is equal to the latitude of the location. A detailed procedure of how to achieve an optimum output from solar power system was done. This process was done using both software and manual analysis, to determine the tilt angle, azimuth degrees, PV module etc. The method used in the thesis is very helpful to calculate the maximum number of solar insolation as a function of latitude and module angle.A mathematical model is used for estimating the total (global) solar radiation on a tilted surface, and to determine the optimum tilt angle and orientation (surface azimuth angle) for the solar collector in India at four different locations on a monthly basis, as well as for a specific period. The optimum angle was computed by searching for the values for which the total radiation on the collector surface is a maximum for a particular day or a specific period. The results reveal that changing the tilt angle 12 times in a year (i.e. using the monthly-averaged optimum tilt angle) maintains approximately the total amount of solar radiation near the maximum value that is found by changing the tilt angle daily to its optimum value. This achieves a yearly gain in solar radiation of 4.56% more than the case of a solar collector fixed on a horizontal surface. This thesis includes 10 chapters. In Ist chapter we study the global market overview and different kinds of collectors and arrays. Second chapter gives the information based on various literature reviews with problem identification and our aim for this research. Third chapter is the methodology of the thesis which includes the several models, definitions used in this work. Chapter 4 shows the calculated results based on the literature review and data available. Chapter 6 shows the conclusion of the work. Chapter 7 shows the scope for the future work. Chapter 8 consists of the references used for the study .chapter 9 is the Publications of the author in Research Journals and finally the Chapter 10 shows the curriculum vitae of author.ACKNOWLEDGEMENT
