The Department of Visual Arts, University of Cross River State operates within the Visual Arts Building, a 2-storey block with offices, 18 undergraduate and postgraduate studios. Students spend day times learning and night times doing practicals and assignments within each studio. Since the studios are enclosed, lighting is needed even in the day time. Sadly, lighting has remained a major limitation in all the studios. Power supply from the Port Harcourt Electricity Distribution Company (PEDC) hardly comes, and the university’s central diesel generator is epileptic and inadequate to provide enough power to light the studios through days and nights. Much work time is lost to darkness, and lectures, tutorials and practicals are severely hindered by the darkness that envelopes the studios. Using a hybrid configuration of 24V 200W ver,cal axis wind turbine, 3 pieces of 24V 200W solar PV and 40 pieces of DC 24V panel lights, this study sought to design and install a DC 24V 800W rooftop solar-wind-mains hybrid energy system to light the studios of the Department of Visual Arts, University of Cross River State.
