The pressure field on the upper and lower surfaces of a photovoltaic (PV) module comprised of 24 individual PV panels was studied experimentally in a wind tunnel for four different wind directions. The results show that the pressure distribution on the module surface is symmetric about its...

This paper presents an application of the neural networks for identification of the maximum power (MP) and the normal operating power (NOP) of a photovoltaic (PV) module. Two neural networks are developed; the first is the maximum power neural network (MPNN) and the second is the normal operating...

The outdoor performance of thin film technologies is not so satisfactorily understood as that of crystalline silicon. Despite all PV materials are influenced by the spectral irradiance, thin film PV modules are especially sensitive to it. Thus, the spectral factor (SF) is a useful index to...
