Title: Comparative Evaluation Of Single Sensor Based Maximum Power Point Tracking Techniques For Photovoltaic Water Pumping Systems   

Author Name: A.Daoud, A. Midoun   

Synopsis:   

This paper presents a comparative study of single-sensor based Maximum Power Point Tracking (MPPT) techniques for solar photovoltaic (PV) systems. The proposed techniques employ conventional hill climbing algorithm to find and track the MPP, using single-sensor methods which are based on either a tachometer or manometer or voltage sensor. Description and analysis of the proposed techniques are presented and verified experimentally on DC/DC buck converter controlled by a low-cost 8-bit PIC microcontroller.
