Design of Off - Grid Solar Photovoltaic (PV) System for Cottage Hospital

Abstract

The provision of adequate and sustainable power supply to the country’s citizen has been a mirage since the 1980’s when the nation neglected to improve its power generation capacity. The rapid population and increase in industrial activities necessitate the injection of solar photovoltaic technology into nation’s energy mix. The need to power cottage hospital in developing country like Nigerian is too enormous. This seminar paper is an attempt to design off-grid solar PV system for cottage hospitals. In this study, I consider the appliances needed for cottage hospital to function effectively, the end used application include (Energy saving bulb, fan, DVD player, radio, television and refrigerator). The power is derived from fifteen 100W PV solar panel unit and the total load power of these appliances is 4925Wh/day.
