Artificial Neural Network Based Model of Photovoltaic Thermal (PV/T) Collector

This paper presents a new application of Artificial Neural Network (ANN) for modeling a Photovoltaic Thermal collector (PV/T). Both thermal and electrical modeling performed. Ambient temperature ofcollector, cell temperature, fluid temperature at duct inlet, fluid velocity in duct, solar identity and timeare used in the input layer and the thermal efficiency and electrical efficiency are outputs. Networks with different hidden layers used for modeling and performances evaluated with maximum correlation coefficient (R2), minimum root mean square error (RMSE) and low coefficient of variance (COV). Theresults showed that the ANN with 1 hidden Layer and 10 neurons in this layer has the best performance. The experimental data measured at meteorological conditions of Zahedan were used as training data. The Levenberg-Marquard backpropagation algorithm has been used for training network. The results of this work indicated that for evaluating PV/T performance researchers can use this method by conductinglimited experiments
