dc.description	Solar photovoltaic systems provide direct conversion of sunlight into electricity and the intensity of solar radiation is the most important parameter which is linearly related to the solar system performance. Hence, the solar radiation received on the surface and performance of the solar system should be investigated with regards to climate zone. Estimation of the solar radiation received on the surface and performance of a solar system under clear sky conditions is detailed and developed models are accurate with the least prediction and calculation errors, while random and anisotropic nature of diffuse radiation in tropical climate makes it extremely difficult to accurately predict the incident solar radiation on the receiver and evaluation of a solar system performance. The principal theme of this thesis relates to achieve the accurate models and approach for the estimation of the solar radiation received on the surface and the solar photovoltaic system performance with regards to the tropical climate of Malaysia. This study is based on a combination of experimental and theoretical work to validate modeling and simulation by simultaneous experimental measurements of global solar radiation and electrical performance of the PV system as a function of angle, orientations, and climate zones. Modeling and simulation on PV system include the mathematical model for predicting incident solar radiation on the PV module as a function of climate zone, slope angle and orientation of panel, the mathematical model for characterizing the thermal response of solar module, and mathematical and numerical methods aimed at optimization of solar radiation and manage output power. Furthermore, the impact of all significant parameters on solar photovoltaic system performance has been considered separately along with a comprehensive review of the impact of the solar radiation intensity, climate zone, direction, and angle of a panel on the solar system. The results indicated that the combination of Louche and Gueymard models was appropriate to estimate global solar radiation components under tropical climate and new optimization algorithms based on this combination model were capable to determine optimum angle and orientation. Based on obtained results, the yearly optimum angle was determined 4.25-degree at the south direction for Bandar Baru Bangi. Finally, the results exhibited that using the energy balance model based on the heat diffusion equation to achieve module temperature and a combination of Gueymard and Louche models to estimate global solar radiation received on the module was appropriate to accurate predictions of solar system performance under Malaysian climate. In general, obtained results indicated that the accuracy reduced with increasing slope angle, and in raining and cloudy skies, due to non-uniform solar radiation distribution and high level of diffuse radiation, the intensity differences between various orientations reduce and the accuracy of prediction is decreased. In summary, this thesis indicated the capability to predict solar radiation incident on the horizontal and sloped surface, determine the optimum angle and orientation, and evaluate the performance of a solar photovoltaic system with low errors in Malaysian climate. In addition, evaluation of modeling and simulation developed in this study in terms of the accuracy at higher slope angles, using similar studies in other types of solar systems and different climates, and utilizing solar concentrating systems are recommended.,Ph.D.
