Development of a neural network model to predict daily solar radiation

Modelling, interpolation and stochastic simulation in space and time of global solar radiation

“…Examples of this approach are the works of Brinsfield et al (1984), Bristow and Campbell (1984), Hargreaves et al (1985), Donatelli and Marletto (1994), Donatelli and Campbell (1998). Other methods also use rainfall measurements (Hodges et al, 1985;Reddy, 1987;McCaskill, 1990;Bindi and Miglietta, 1991;Hook and McClendon, 1992;Nikolov and Zeller, 1992;Elizondo et al, 1994). Hunt et al (1998) compared several of the above methods.…”

An application of the Multilayer Perceptron: Estimation of Global Solar Radiation and the Establishment of Solar Radiation Maps of Togo

“…In another study, Yang and Koike [16] utilized upper air humidity values for the estimation of solar radiation on the surface of the earth through ANN method. Other authors used MLP method as can be seen from these references (Elizondo et al [17]; Al-Alawi and Al-Hinai [12]; Mohandes et al [18,19]; Togrul and Onat [13]; Hontoria et al [20,21]; Tasadduq et al [22]; Kalogirou et al [14]; Tymvios et al [23]). The present paper utilizes the air temperature, relative humidity and the latitude of Lomé, Atakpamé and Mango data as input in neural networks for the prediction of global solar irradiation (GSR) on horizontal surfaces in seven other cities in Togo, and to establish its solar maps.…”

Evaluation of an improved daily solar radiation generator for the southeastern USA

“…The availability of recorded daily solar radiation (SR) data has been limited to recent years, mainly due to the high cost of the instrumentation, maintenance and calibration of pyranometers and other sensors (Elizondo et al 1994). However, daily SR data have become more readily available with the introduction of automated weather stations (Hook & McClendon 1992).…”

“…Then, a location-specific linear and cosine correction factor was determined and introduced to their equation. Elizondo et al (1994) used a neural network approach to estimate daily SR as a function of recorded weather variables, including daily precipitation, maximum and minimum air temperature, and calculated variables, including clear sky radiation and day length.…”
