Computer-Aided Design Of A Stand Alone Photovoltaic System A Case Study Of Faculty Of Engineering Bayero University Kano.

Abstract In this paper the electrical energy demand load of the Faculty of Engineering Bayero University Kano BUK was estimated based on watt-hour energy demands. A stand alone Photovoltaic PV system was designed based on 10 of the estimated load to supplement power supply to the faculty. Based on the equipment selected for the design 96 PV modules 24 batteries 5 voltage regulators and an inverter will be required to supply 10 of the electrical energy demand by the faculty. A computer program was developed for the system for ease of design. The cost estimate of the systemN2 788 272 is relatively high when compared to that of standby fuel generator used by the faculty. The payback period of the system is estimated to be 3.6 years which is obviously much shorter than the lifespan of the selected PV module.
