Solar energy analysis of a home by considering outdoor parameters

In this thesis, solar energy analysis is performed for a home placed in Anadolu University İki Eylül Campus by considering outdoor parameters. Within the scope of this analysis, hourly global solar radiation values on horizontal surface are estimated from measured daily global solar radiation values by using eleven different models. The measured and estimated hourly global solar radiation values are compared and accuracy of the models is evaluated using statistical analysis methods. The obtained results indicate that Collares - Pereira and Rabl model modified by Gueymard (CPRG) has generally the highest accuracy among all considered models. By using Olmo et al. model, the estimated hourly global solar radiation values of CPRG model for horizontal surface are converted to values for inclined surface. In addition, cell temperature of the photovoltaic modules is estimated with seven different models that consider outdoor conditions and panel technical characteristics defined by manufacturers. Hence, based on the estimated cell temperature and global solar radiation values on inclined surface, power generation values of on-grid and off-grid systems are predicted with a model in MATLAB, and these values are compared with actual power generation values. It is seen that cell temperature values estimated by the standard approach give the best prediction values of power generation.
