The performance of dc motors powered by a solar cell generator and loaded by two different types of loads, one a constant load and one a ventilator load, were analyzed with respect to the transient and steady state operation. Direct current motors are employed in photovoltaic water pumping systems. The performance characteristics of the dc motor are different when supplied by a solar cell generator than when supplied by a conventional constant voltage source. The transient solution was obtained by using an available computer program - SUPER SCEPTRE. The separately - excited motor with a ventilator load was found to be the most suitable for the solar cell generator. The series motor is acceptable, but the shunt motor gives poor performance.
