Abstract

 Electrical motors powered by solar cell array (SCA) generators have important applications such as water-pumping for irrigation or water supply. Good matching of loads 10 solar cell generators is so important for optimum operation of the PV system and maximum utilization of solar energy. This paper applies a graphical technique to analyze the performances of directly coupled PV electro-mechanical systems for dc motors (that is, series separately excited and shunt motor) coupled to ventilator, centrifugal or constant loads. The technique depends on simulating the electrical characteristics in (I, V) plane, the mechanical characteristics in (T,𝟂) plane, and the hydraulic characteristics in (H,Q) plane. A comparison between different case studies is introduced to indicate the appropriate motor type for each load. The comparison depends on: quality of load matching, system efficiency and the insolation level at which the motor starts up. The effect of connecting a storage battery for each case study is also, investigated.
