When we tested the neural network with different irradiance and temperature, we see that the neural network can accurately predict the maximum power point of a photovoltaic array. The data collected from the system is used to train the neural network. We collected a set of data from the Simulink model of PV array after simulated under a range of irradiation and temperature. The Simulink model is tested with different temperature and irradiation and resultant I-V and P-V characteristics proved the validation of Simulink model of PV array. The MATLAB/Simulink is used to establish a model of photovoltaic array. In this paper, we present our work on Maximum Power Point Tracking (MPPT) using neural network.
