“…There are different methods of seawater and brackish desalination appropriate for Egyptian environment and recommended the method of selection of the technology to be used in each particular site where the possible energy sources are screened. A small scale reverse osmosis (RO) desalination system powered by renewable energy sources presents an ideal solution to provide freshwater to small communities isolated at remote areas [5]. In the last decade, desalination, especially by RO, has become one of the principal safe sources of supply of potable water, and even water for agricultural use, it is in the Mediterranean, Africa, the Middle East, and so on, where the potable water supply is a high priority problem.…”

The main objective of this work is to design an optimal—efficient economic power renewable energy system that feeds the required electric load of a small scale brackish reverse osmosis desalination unit and a tourism motel located in Hurghada, Egypt. Four renewable energy power systems are presented in this paper to select the most optimum one of them. These suggested renewable energy systems are PV-wind hybrid system, stand-alone wind system, stand-alone photovoltaic system and PV-wind-fuel cell hybrid system. The sizing, optimization and economic estimation of the proposed systems were performed using HOMER software. HOMER solves the optimization problem to minimize the global cost and provides the optimum wind turbine, PV, battery and fuel cell ratings. In addition, a comparison between the four different suggested power system configurations is illustrated in details. PV-wind hybrid system realized the lowest net present cost and levelized cost of energy. Also, this system was able to provide energy approximately all the day. The battery state of charge varies between 83% and 99% and it was found that, the PV-wind hybrid system is more suitable than the others for the selected site and the suggested electrical load

a b s t r a c tIn this work complete analytical modeling, simulation with experimental verification of photovoltaic system driving reverse osmosis water desalination is presented. In photovoltaic system, solar radiation and PV generation modeling is done and investigation of the effect of fixed and tracking PV panel on the collected insolation and PV power is carried out. In the RO section, complete model of RO membrane is developed that estimates the feed water pressure and permeate flow rate. The developed PV and RO models are validated individually as well as integrated (combined PVRO) by experimental data and show good agreement. By using this validated model the effect of slope and azimuth angle of the PV panel is studied on the permeate flow rate for the whole year. The increments in the clean water flow rate for the yearly tilt, monthly tilt, single and double axis tracking PV panels with respect to traditional flat panel is computed. The estimated results reveal that yearly optimal tilt angle of PV panels due south is close to the 0.913 times latitude of the Dhahran city. Yearly permeate gain with the yearly optimal tilt, monthly optimal tilt of PV panel relative to flat panel installation is 10% and 19% respectively. The optimization of photovoltaic system suggests the adjustment of the PV orientation (tilt angle and azimuth angle) by using a single and dual axis tracking system installations. The yearly permeate gain made by single and double axis continuous tracking PV panels is 43% and 62% respectively.

“…Among the renewable energy powered RO desalination applications, stand-alone PVRO plant has been demonstrated to be feasible both in terms of techniques and costs in lab-scale and pilot-scale systems [14e17]. At present, it is considered as a proper solution for small-scale desalination applications in rural areas with high solar insulation [18]. The effectiveness of the stand-alone plant depends on the location, geographical conditions, topography of the site, and the capacity of the plant.…”

a b s t r a c tA novel RO seawater desalination plant powered by PV (Photovoltaic) and PRO (PVROPRO) is proposed and the feasibility of two stand-alone schemes, SSRO (salinity-solar powered RO) operation and SRO (salinity powered RO) operation, are investigated. First, the stand-alone feasibility of the plant is thermodynamically analysed. In doing so, on the basis of mathematical models describing RO, PRO and the PV array, the stand-alone feasibility is numerically investigated and the feasible operational windows for the two operation schemes, SSRO and SRO, are identified. In addition, the detrimental effects, CP (concentration polarization) and RSP (reverse salt permeation) in the mass transfer, on the operational windows are investigated. Finally, a case study of the proposed PVROPRO plant is developed based on the hourly solar data of Perth Australia in a year. The highest weekly production rate is found to be almost 20 times the rate in PVRO in the same week. Annual production is increased more than nine times compared to the stand-alone PVRO plant. Furthermore, it is found that, due to detrimental effects the weekly PW (product water) production rate is decreased in the range of 16e20% and the overall annual reduction is 18.07%.Crown
