Techno-economic Feasibility of Photovoltaic System for an Educational Building in Egypt : (Case Study)
The fluctuation of fuel prices has become a concern to the Egyptian society since it influences the electricity tariff. The objective of this paper is to design a self-consumed power system for an educational building from a photovoltaic (PV) source. Two proposed systems, grid-connected and standalone, are suggested and compared to the currently running grid supply system. The comparison is implemented from a techno-economic point view through calculating the net present cost (NPC), the levelized cost of energy (LCOE) and the return of investment (ROI) when applicable. The study showed the leading of the grid-connected system over the standalone one whenever a grid is already connected to the area. an overall reduction of more than 50% in NCP and 75 % in LCOE was recorded.
