TL;DR: In this paper, the global, diffuse and direct solar radiation empirically on a horizontal surface for the divisional district "Khulna" in Bangladesh (latitude 22o47΄N and longitude 89o34΄E) as well as predict correlations for it by using several meteorological data for 32 years between 1980 and 2012.
Abstract: This study is accomplished to calculate global, diffuse and direct solar radiation empirically on a horizontal surface for the divisional district “Khulna” in Bangladesh (latitude 22o47΄N and longitude 89o34΄E) as well as to predict correlations for it by using several meteorological data for 32 years between 1980 and 2012. The global radiation is found to be maximum in the month of April and minimum in the month of December here. The estimated values of the Angstrom’s regression constants a and b are 0.2388 and 0.5228 respectively. The other regression constants were also computed and the correlations proposed for Khulna can be used in future for the estimation of global, diffuse and direct solar radiation if the meteorological parameters remain available.

TL;DR: In this article, the authors investigated the solar radiation prediction in Kuala Terengganu, Malaysia and developed and tested Genetic Programming Techniques (GP) models to predict solar radiation.
Abstract: The solar radiation prediction in Kuala Terengganu located in Terengganu, Malaysia was investigated in this study to improve the solar system design. Solar radiation data and number of parameters such as solar radiation, temperature, humidity, wind speed and sunshine hours were obtained from Malaysian Meteorological Malaysia MMD. In order to predict the solar radiation, Genetic Programming Techniques (GP) models were develop and tested. Two scenarios were considered in this study in order to validate the efficiency of the proposed model. Coefficients of determination (R2) for the solar radiation during training and testing phases were ranged between 0.99402 to 0.98934 for all months of the year. This study confirms the ability of GP to predict solar radiation values precisely and accurately. The predictions from the GP models could enable scientists to locate and design solar energy systems in Malaysia.
