_Potential of Renewable System Powering a Mosque in Libya

This paper presents a techno-economic analysis of a hybrid renewable system powering a remote mosque in Libya. Daily energy consumption profile for the four seasons is estimated based on a medium size mosque. In Libya, spring and autumn weather conditions are not as extreme as winter and summer; this decreases the load demand during these seasons. Therefore, summer and winter weather conditions are used as the basis where peak energy demand is expected because air-conditioning and heating loads are dominant. Winter electrical load is found to be the highest. HOMER software tool was used to determine the optimum size and specifications of renewable power system. When solar and wind are at their minimum values (4.32 kW/m2/d, 3.79 m/s) and the fuel price is assumed as a maximum (0.75$), the most economically power system is PV/Gen/Battery with total net present cost (NPC) of 184094$, cost of energy (COE) of 0.478$/kWh, and renewable fraction (RF) of 31%. When solar, wind and fuel price are assumed at average values of 6.34 kW/m2/d, 4.81 m/s, and 0.5$, the optimal solution is also PV/Gen/Battery with (NPC) of 147485$ and (COE) of 0.383$/kWh, and (RF) of 33%. When the solar and wind are assumed at maximum values of 8.06 kW/m2/d, 6.02 m/s, and the fuel price is assumed minimum (0.25$), the most feasible economically system is still PV/Gen/Battery with (NPC) of 119311$ and (COE) of 0.310$/kWh, and (RF) of 29%. The excess electricity from the hybrid renewable power system during spring and autumn can be sold to the utility or used for other applications. This will enhance the feasibility of renewable power systems at remote mosques.
