This thesis uses the results of analysis of data recorded at a solar monitoring station in West Texas and the knowledge from an existing solar radiation estimation model to develop a methodology to predict the energy output from a panel at a site using only partial radiation data - global horizontal radiation measurements. The prediction using partial data is validated against estimates acquired using the complete radiation data and constraints are defined for accurate prediction. The methodology presented in this thesis can be used to accurately predict the solar power/energy incident on a collector at any location possessing global horizontal radiation measurements. / text
