Large market opportunities exist for solar powered Reverse Osmosis (RO) desalination tech-nologies in fertile but arid areas with large solar and sea water resources. A challenge to real-izing these markets is the variable nature of solar resources, which for the desalination plant can lead to high water costs due to low capacity factors (CF) and increased maintenance costs due to repeated start-ups and shut-downs. A potential solution is to power RO plants using both PV and CSP with Thermal Energy Storage (TES) with an aim to reduce shut-downs, and increase CF. In this study, three solar energy systems to power RO are consid-ered: 1) PV only; 2) CSP with central receiver (CR) and TES; 3) PV and CSP with CR and TES. Two RO operational strategies are considered: 1) nominal load only; 2) variable load between minimal and nominal. The performance of these systems is simulated for Mersin, Turkey, using TMY data. The PV and CSP with TES system and variable RO operation achieved the levelized cost of water (LCOW) (1.92 USD m-3) with an RO CF of 60.8%.

Hadjdida, Abdelkader; Bourahla, Mohamed; Ertan, Hulusi Bülent; Bekhti, Mohamed (2018-12-01)
Currently, solar energy is promising the primary source of renewable energy that has a great potential to generate power for an extremely low operating cost when compared to already existing power generation technologies. Increasing the efficiency of solar cells is a major goal and the prominent factor in photovoltaic system research. Current triple junction solar cells reach 30% and the next generation will bring 35% in 5 years to peak at 40%. These cells are used in space environment and in terrestrial sy...
Dual-band perfect metamaterial absorber for solar cell applications
Rufangura, Patrick; Sabah, Cumali (2015-10-01)
The efficiency of solar photovoltaic (PV) cells has been one of the major problems impeding its global adoption as one of the sustainable substitutes to fossil fuel based technologies. Metamaterial (MTM) based solar cells offer an opportunity towards increasing the system efficiency by enhancing the total absorbed solar radiation incident on this device. In this study, a nanostructure-based MTM perfect absorber has been designed and simulated. By adjusting geometrical parameters and MTM structure properties...

Yılmaz, Arda; Kıncal, Serkan; Department of Chemical Engineering (2017)
Nowadays countries investigate to improve alternative energy technologies such as solar power, biomass, wind energy, hydrogen etc. Hydrogen gas is very useful energy carrier and fuel cells produce electricity through hydrogen gas. Hydrogen production technologies are also investigated by many researches due to its high cost production. Thermochemical production way is one of the hydrogen production methods. Solar energy is also clean, renewable and alternative energy source. It is used for heating reaction ...
Study Case of Solar Thermal and Photovoltaic Heat Pump System for Different Cities in Turkey
Moia-Pol, Andreu; Pujol-Nadal, Ramon; Martinez-Moll, Victor; Bonyadi, Nima; Baker, Derek (2016-10-14)
The combination of solar thermal, photovoltaic, and heat pump technologies is a welcome advancement in countries with large solar resources such as Turkey. These systems could have similar efficiencies throughout the year for different locations in Turkey if we adjust the solar storage according to the weather conditions. In this paper, solar heating with a heat pump system for buildings have been designed to achieve different values of the fraction of primary energy saved using Flat Plate Collectors (FPC) ...
Smart Solar Micro-grid Using ZigBee and Related Security Challenges
Qadir, Zakria; Tafadzwa, Vincent; Rashid, Haroon; Batunlu, Canras (2018-11-02)
Renewable energy is needed to preserve a sustainable environment. One particular form of renewable energy (solar energy) is one of the most important and cost-effective solutions to the energy crisis. In this study, efficient solar energy management using ZigBee technology shall he discussed. The system informs the user when solar panels produce excess power before supplying it to the surrounding users, thus making the supplier a prosumer instead of a consumer. GSM which is used to monitor energy usage over...
