“…In Türkiye, several studies in the literature have been carried out by the researchers for different purposes and regions about optimization of tilt angle, the orientation of solar surfaces, and calculation of solar radiation values. Most of the studies to determine the solar radiation potential of a certain location were focused on the determination of total radiation falling on a horizontal surface using measured data [4][5][6][7]. Several solar radiation calculation models are performed in the literature by using Artificial Neural Networks [8,9] and Machine Learning [10,11].…”

Solar energy has gained increasing importance in today's world and become a viable primary energy source in the recent decade. Solar radiation obtained by the solar surface is highly affected by its orientation, azimuth, and tilt angles. Therefore, in this study, the performances of the fixed-axis system, one-axis, and two-axis solar tracking systems are investigated to enable maximal solar radiation in solar systems to be installed in Antalya by using climatic and latitude data provided by NASA. Furthermore, the optimal tilt angles are determined by examining the values of angles for which the total solar radiation falling on the tilted surface is maximal. The case study and measurement data investigations are conducted for the four districts of Antalya. The obtained radiation values throughout the year for one-axis and two-axis solar tracking systems are compared to an annual fixed system for evaluating the existing solar potential in Antalya province. Besides all these, solar system cost analyses including the average payback period for residential, commercial, and large-scale solar systems based on LCOE are investigated. The proposed methodology can be implemented for performance and cost analysis of the solar potential in a certain location of Türkiye and extended to any place in the world.

Global solar radiation estimation is crucial for regional climate assessment and crop growth. Therefore, studies on the prediction of solar radiation are emerging. With the availability of the public data on solar radiation, computerized models have been developed as well. These Predictive Models play significant role in determining the potentials of regions suitable for renewable energy generation required by engineering and agricultural activities. Herein a computerized model has been presented for estimating global solar radiation. The model utilizes random forest algorithm and reached predictive value of 93.9%.

“…The clearness index K t is a dimensionless number, which ranges between zero and one and measures the attenuation degree of extraterrestrial solar irradiation H 0 along its path from the external surface of the atmosphere to the earth surface. The monthly clearness index is defined as follows [9,26]:…”

“…The first work which was carried out by Angstrom in 1924 [6][7][8], proposed a relation between the global radiation on a horizontal surface and sunshine fraction. After some year, exactly in 1960, Liu-Jordan proposed a relation between the diffuse fraction and the clearness index [9]. Considering that, these two proposed correlations were original discovers in this field at that time and which were developed to be applied for daily intervals, they were used for the calculation of the diffuse fraction as a function of the clearness index k t and as a function of the sunshine fraction σ for hourly intervals.…”

This paper presents a comparison study between the measured solar radiations on site and the calculated solar radiation based on the most theoretical models presented in the literature up to date. Indeed, for such purposes, this paper focusses on the analysis of the data of the measured solar radiation collected on two sites in Algeria such as Tlemcen (34°52′58″ N 01°19′00″ W, elevation 842 m) and Senia (35°39′ N 0°38′ W, elevation: 77 m). In order to check the accuracy of the proposed model, the experimental collected data of the solar radiation obtained from the existing radiometric stations installed at the two locations under investigation, are compared with the estimated or predicted solar radiations obtained from the Capderou and R.Sun models, where four days under clear skies are selected from different seasons to achieve this comparison. Second, the daily averages of the experimental global solar irradiation are compared to those predicted by Mefti model for both the sites. Finally, a validation is carried out based on the obtained experimental monthly global irradiations and with those estimated by Coppolino and Sivkov models. A relative difference is used in this case to judge the reliability and the accuracy of each model for both sites.
