A PV system to operate a VHF transposer station

Thirteen yeas of cruel embargo imposed on Iraq, pushed people there to do a lot of things to keep survive. The main tradition distinguished that period is innovation and modification, depending upon the decreased available capabilities. In that spirit, a suitable PV system was designed to operate a VHF driver 50 w transposer. Modifications were made in some parts of the transposer unit to make it suitable for operation through the PV system. Different values of the inclination angle were examined, and the one with minimum peak power demand was chosen for the design. The designed PV system is composed of 144 solar modules, two regulators and 17 storage batteries. Each solar model has an area of 1 × 3 ft and a specification of 14.5 V, 759 ma and 11 W. Each storage battery has a specification of 12 V and 90A.h. The designed system provides sufficient energy to operate the transposer for 16 h daily and the storage system provides energy to the system for 3 consecutive days without insolation. The system was designed to be installed in a remote area near Baquba City. An evaluation of one year’s operation is made for the whole system.
