Humans rely heavily on energy in their daily activities and the demand is increasing. The conventional energy resources are limited and unequally distributed. Hence, a global requirement for sustainable energy provision becomes increasingly important. A feasibility study of electricity supply with solar photovoltaic energy at the University of Ngaoundere in Cameroon is presented. Evaluations showed that, for an estimated need of approximately 969 kWh/day, 3 162 solar panels (125 W, 24 V) are necessary to overcome the energy needs of the institution. The overall investment cost is estimated to 153 301 485 US dollars (approximately 77 billions CFA). A simulation showed that the payback time of the investment is approximately nine years while a gain of 3 671 893 US Dollar (approximately 2 billion CFA) is performed.
