Research ArticleOpen accessEvery word in the titleForecasting the Diffuse Solar Radiation by using a New Modeling over Saudi ArabiaSamy A. KhalilWithin the arranging and execution assessment of solar energy projects, particularly within the planning and estimation of solar photovoltaic sources as elective energy sources within the future, exact evaluation of Diffuse Solar Radiation (DSR) is one of the essential and basic issues. The target of this article is to use the new model to predict DSR in four different locations … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 5 May 2021 · 7,352 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleObservation Modeling for Continuous Predicting Global and Diffuse Solar Radiation on Horizontal SurfaceSomporn Hongkong, Singthong PattanasethanonMathematical modeling for continuous prediction of solar energy is inevitable for energy systems. General, existing models are mostly empirical and data dependent. This article has to present a variable model for predicting global and diffuse solar radiation on the horizontal plane. The model considered in this study has applied Hidden Markov Model (HMM) with two observations. The databases were measured … …American Journal of Environmental Sciences, Vol. 9, Issue 3 · 23 May 2013 · 6,797 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSolar Radiation at Total Solar Eclipse, 29-March 2006, at TobruqA. H. Hassan, U. Ali RahomaProblem statement: Measurement of the different components of solar radiation and fractions of these components for the global (horizontal and tracker), direct (white and three colors, yellow, red and infrared) and diffuse solar radiation during the solar eclipse, 29 March 2006 at Tobruq, Libya (Lat. 32.08°N and Long. 23.98°E). The time interval of solar eclipse was 2 h: 40 m … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,824 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsSimulation of Solar Radiation SystemM.S. Alam, Sushanta Kumar Saha, M.A.K. Chowdhury et al.In this research work, a mathematical model for simulation of the solar radiation system has been developed by using a system dynamics methodology. Bangladesh is used here for model validation. The simulated results obtained from this model have compared with the experimental results and found reasonably a good agreement. Therefore the performance of the model is to be expected as … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,695 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMultiple Linear Regression to Predict Electrical Energy Consumption Based on Meteorological Data: Application to Some Sites Supplied by the CEB in TogoApaloo Bara Komla Kpomonè et al.The prediction model developed in this article is based on the use of meteorological variables to estimate the consumption of electrical energy at the substations of the Electric Community of Benin. The objective is to predict this consumption in order to adapt production to it. The posts (Lomé Aflao, Légbasito, and Lomé port) are the targets that were used in … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 10 Jun 2024 · 5,785 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCritical Retrospect on Conventional and Luminescent Solar Concentration DevicesHamzah Abdul-Rahman, Chen WangProblem statement: Conventional solar concentrators are only sensitive for the beam radiation and they function poorly in overcast sky conditions. Even under a clear sky condition, trackers are always needed for conventional solar concentrators. Static concentrators always come with a poor concentration rate without a tracker and the light concentrated by normal Luminescent Solar Concentrators (LSC) could not be transported … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,924 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEstimate of Aerosol Optical Depth Using Broadband Direct Normal Observations at Highest Polluted Area in the WorldU. Ali Rahoma, A. H. HassanProblem statement: The measurement of different components of direct solar radiation for this research has been carried out in Helwan, Egypt. Helwan (Latitude 29°52 N, Longitude 31°20 E). This is a considered as the largest polluted region in the world. The level of pollution in Helwan region is higher, compared to the international limit by about 7 or 10 times … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,069 accessesView PDF Cite
