Present article is a review of recent researches on linking the satellite image data to surface measured bright sunshine hours. It first gives some basics on estimation procedures of the daily global solar irradiation on horizontal surface with the daily bright sunshine hours. Second, a satellite based model is presented briefly. Then, two recent combined models are reviewed and compared with the conventional models. The results on using one of the presented methods are discussed and recommended, for a couple of various cases which are classified by available data of the site of interest. It is concluded that the use of one of the combined model gives one of the best estimation performance for the daily global solar irradiation at the Earth's surface, whenever both of the data of bright sunshine and cloud index are available. However, satellite based model HELIOSAT also performs with high accuracy except for a number of days of one of the data sets. Hence, another conclusion is that, for the daily estimations, the use of HELIOSAT type satellite based models should be preferred, instead of using an Angstrom-Prescott type correlation of a location at a far point and/or having a different climate. Finally, a quadratic correlation which was tested for too many locations all over the world also performs quite accurately. Therefore, if only the bright sunshine hour data is available for a site, use of this quadratic correlation should be preferred. (C) 2013 AIP Publishing LLC.

The analysis on sun tracking and cooling systems for photovoltaic panels RÜSTEMLİ, SABİR; Dincer, Furkan; ÜNAL, EMİN; KARAASLAN, MUHARREM; Sabah, Cumali (Elsevier BV, 2013-06-01) This paper presents a review study on the effects of sun tracking and cooling systems. So far, many studies (and case studies too) have been analyzed and evaluated in the literature. Existing studies show that sun tracking system is significantly affecting energy generation capacity of photovoltaic panel. Other effecting parameter is the cooling system which has small effect on PV panel power generation but this totally depends on the location of installation system.

Comparisons and critical assessment of global and diffuse solar irradiation estimation methodologies Karaveli, Abdullah Bugrahan; Akınoğlu, Bülent Gültekin (Informa UK Limited, 2018-01-01) Defining better methodologies of accurate predictions of the amount of monthly mean daily global and diffuse solar irradiation exposed is of utmost importance in order to determine the potential for utilizing the solar energy. This study compares and discusses the main methodologies, databases, and software that are used in estimating the solar irradiation to be used for the short- and long-term performances and feasibilities of solar energy systems, especially photovoltaic power plants in Turkey, and addre...
CONSTRUCTION OF A QUADRATIC MODEL USING MODIFIED ANGSTROM COEFFICIENTS TO ESTIMATE GLOBAL SOLAR-RADIATION Akınoğlu, Bülent Gültekin (Elsevier BV, 1990-01-01) In this paper, a new correlation for the estimation of monthly average daily global solar radiation will be presented and compared with the correlations of Rietveld, Benson et al., Ögelman et al., and a recent formulation by Gopinathan. The overal results show that the quadratic form gives better performance in terms of global applicability. The new quadratic model should be preferred for the monthly average global solar radiation estimation when the data for bright sunshine hours are available
Technical and economic assessment of fixed, single and dual-axis tracking PV panels in low latitude countries Bahrami, Arian; Okoye, Chiemeka Onyeka; Atikol, Ugur (Elsevier BV, 2017-12-01) This study aims to contribute towards developing a sustainable roadmap for electrification program via solar energy deployment in 21 low latitude countries (0-15 degrees N) with limited access to the grid. Firstly, the available electrical energy from fixed, single and dual-axis solar tracking PV panels is demonstrated using a case study of nine selected locations in Nigeria. The annual electrical energy for the locations from a fixed 1-kW PV panel tilted at an optimal angle ranges from 1485 to 2024 kWh, wi...
Solar generated steam injection in heavy oil reservoirs: A case study Afsar, Cansu; Akın, Serhat (Elsevier BV, 2016-06-01) Combination of solar generated steam technology and enhanced oil recovery (EOR) techniques have attracted a great deal of attention due to its positive impact on economics and on the environment. Solar steam project has already proven itself as it can reduce both gas consumption and CO2 emissions by up to 80%. However, operational issues as well as geographical factors (i.e. terrain suitability, drill sites and future field development plans) may affect solar EOR operations. In this study, a heavy oil field...
