This study presents a methodology to assess suitability of a site for small scale concentrated solar power (CSP) systems for its energy conversion efficiency and make-up water requirement. Energy conversion efficiency of CSPs relies not only on the level of direct solar radiation but also on the performance of the cooling system. Regions with high solar potential have to deal with heat rejection at elevated temperatures which causes reduced energy conversion efficiencies due to high condenser temperatures. It is desirable to utilize wet cooling systems as they can achieve temperatures lower than the dry bulb temperature by evaporative cooling. On the other hand, such regions usually lack water resources which deteriorate the sustainable nature of CSP applications. This study combines various available models for both solar resource estimation and cooling systems' performance considering (i) the influence of ambient temperatures, and (ii) the influence of humidity levels. These models are integrated together to analyze the use of dry or wet cooling systems in terms of overall energy output and water consumption at a selected site in northern Cyprus. The model inputs consist of only annual hourly surface weather data and the location of the site of interest. The results show that dry cooling unit at northern Cyprus is capable of saving water about 18.7ton/MWh while it produces 27% less energy compared to the wet cooling alternative for the representative annual weather data.

A Feasibility study for external control on self-organized production of plasmonic enhancement interfaces for solar cells
Zolfaghari Borra, Mona; Bek, Alpan; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2013)
The present study is about the improvement of the energy conversion efficiency of solar cells in which plasmonic light-trapping approach has been investigated. In this study, metal nanoparticles are allowed to form in a self-organized fashion on both flat and textured full scale monocrystalline silicon solar cell. These metal nanoparticles with strong optical interaction cross-sections at localized plasmonic resonance energies, improve coupling of the incoming light into the active area of solar cells by wa...
A system level modeling and performance evaluation of concentrated solar power plant
Hasany, Syed Zaid; Uzgören, Eray; Sustainable Environment and Energy Systems (2013-12)
This thesis presents a system level study for a solar thermal power plant comprising of parabolic trough collectors (PTC), an organic Rankine cycle (ORC) and a wet cooling tower. A transient numerical model is developed for the PTC accounting the thermal losses and coping up with the intermittent and inherent variable solar input. The transient PTC model is validated with the experimental and numerical results and extended to the double pass counter flow PTC configuration. It is found that there is no signi...
An investigation of optimum PV and wind energy system capacities for alternate short and long-term energy storage sizing methodologies
Al-Ghussain, Loiy; Taylan, Onur; Baker, Derek Keıth (Wiley, 2019-01-01)
The goal of this study is to find the optimal sizes of renewable energy systems (RES) based on photovoltaic (PV) and/or wind systems for three energy storage system (ESS) scenarios in a micro-grid; (1) with pumped hydro storage (PHS) as a long-term ESS, (2) with batteries as a short-term ESS, and (3) without ESS. The PV and wind sizes are optimally determined to accomplish the maximum annual RES fraction (F-RES) with electricity cost lower than or equal to the utility tariff. Furthermore, the effect of the ...

The olive mill sludge treatment system developed in this study is an indirect solar dryer driven by a solar parabolic trough collector (PTC). A heat exchanger is implemented to heat air with hot oil coming from the solar collector. The developed hot air dryer can treat up to 50 kg of olive mill sludge distributed over six trays at once. The designed system and its components are described, along with their experimental and simulated performance evaluations. With a mean direct normal irradiation (DNI) higher...
A new economic feasibility approach for solar chimney power plant design
Okoye, Chiemeka Onyeka; Solyali, Oguz; Taylan, Onur (2016-10-15)
Solar chimney power plants have been accepted as one of the promising technologies for solar energy utilization. The objective of this study is to propose an effective approach to simultaneously determine the optimal dimensions of the solar chimney power plant and the economic feasibility of the proposed plant. For this purpose, a two-stage economic feasibility approach is proposed based on a new nonlinear programming model. In the first stage, the proposed optimization model which determines the optimal pl...
