This paper presents a procedure for the proper design of systems comprising photovoltaic solar generators directly supplying DC motors. The method is based on maximizing the total annual gross mechanical energy delivered to a mechanical load with a given torque-speed characteristic. The seasonal variations of both the insolation level as well as the ambient temperature are taken into account. From the required rated output power and the voltage-current characteristic of a single solar cell, the total number of cells can be directly determined. The two unknowns affecting the objective function (the total annual gross energy) are the number of panels in series, or equivalently, the number of strings in parallel, as well as the motor field constant (for separately-excited motors), or the armature-field mutual inductance (for series motors). The proposed technique is applied to two practical case studies, and the resulting optimal design parameters are compared with those available in the literature. A comparison is also made between the optimal separately-excited and series motor design alternatives regarding the annual gross mechanical output energy.
