ABSTRACT
This paper evaluated the design and installation of a stand-alone photovoltaic (PV) system in the office of (HOD, Electrical and Electronics Engineering department in Olusegun Agagu University of Science and Technology, Okitipupa, Ondo State, Nigeria. An energy audit of the office was carried out by inspection and interaction with the occupants of the office. Information obtained was used to evaluate the total power estimated and actual consumption over 6 hours daily. The total energy demand for seven appliances captured in the office was calculated to be 1.92 kW (2.4 kVA) and the total photovoltaic (PV) power required was estimated to be 2.77 kWh. It was established from the design analysis that a minimum of three (3) solar panels rated 180 W each, a battery of 220 AH at 12V, a 1.5 kVA inverter, and a charger controller rated 30A were required to power the office. The efficiency of the PV system is found to be 98.6% at peak load of 765 W.
