A novel single sensor PV MPPT controller

Abstract

This paper proposes a novel single sensor maximum power point tracking method for PV system composed of Solarex MSX-60W PV panel operating at variable atmospheric conditions and DC-DC boost converter controlled using the proposed MPPT that uses only one sensor in order to reduce the cost and the complexity of the MPPT controller. The performance of the proposed single sensor MPPT controller is evaluated using the implemented Matlab/Simulink PV power system model. Simulation results show that the proposed single sensor MPPT controller can provide similar results using only one sensor compared to the conventional two sensors MPPT.
