Instability of electricity supply in Sudan is an increasing problem; especially in the capital and other larger cities. Commercial users such as hotels are looking for alternative solutions in order to be able to deliver adequate standards to their guests. In this study we investigate and optimize combined PV/Diesel system as a main electricity source for a hotel. There is significant potential for the use of the photovoltaic solar energy in countries like Sudan which receive abundant amounts of solar radiation around the year; the present work aims to design a rooftop photovoltaic solar system; or a hybrid system (Solar and Diesel) to produce 88100 kWh/yr of electricity for Rosa Park Hotel in Khartoum. The aim of this feasibility study was to find economic and useful combinations between Diesel and PV systems based on actual electricity consumption data of the hotel; taking into consideration both economic and environmental system aspects.
The study shows that; the PV systems can be used independently or together with the Diesel generator as a replacement energy resource. Due to the high initial cost of the installation of a PV stand-alone systems; the economic optimizations shows that a combination of a relatively small Diesel aggregates with a PV system can result in low system costs taking advantage of free and clean solar energy of PV and the system flexibility of a Diesel system.
