Design of a Grid Connected Photovoltaic System for Institutional Use

A Photovoltaic power system is a system that uses light energy from the sun by converting it into electricity which might or might not be connected to the national grid. Solar radiation was collected by a Pyranometer installed at house rooftop in Otjomuise, Windhoek. The data was used to determine the size of photovoltaic generator required to produce electricity to meet the user demand. This project describes the steps followed while designing a PV system that will produce electricity for the University of Namibia (main campus) at a later stage. A 25.2 kWp grid connected PV system was designed and installed on Y-block rooftop, to meet the university daily energy demand and its annual energy output for the first year was estimated to be about 57.67 MWh.
