Estimation of global solar radiation: A case study of Gaziantep

In this study, the relationship between the global solar radiation and the meteorological variables (average temperature, relative humidity, wind velocity and vapor pressure) for limited data from 2000 to 2010 years obtained from the Gaziantep central meteorological observation station is estimated by formulating using genetics programming technique. The prediction results are compared with the observed ones statistically, and also based on their trend characteristics. The model comparison efforts revealed that linear genetic programming gave the best prediction results. It is believed that the derived genetic programming formulations can successfully be used in feasibility and design stage of solar power plants.
