Renewable energy sources have become an environment friendly alternative to fossil fuels. As a renewable source, solar energy becomes widespread under favor of decreasing costs in Photovoltaic (PV) cell production. Similar to the growth trend in the world, total production capacity of installed Solar Power Plants (SPP) have recently reached over 5 GW in Turkey. In a typical SPP, PV modules are mounted on steel supporting structures with a site-specific inclination angle. In the last years, damage of many PV mounting structures due to snow load has shown that characteristic ground snow load proposed in design load code TS 498 is not suitable for SPP and does not sufficiently represent regional variance of snow climate. In the present study, snow load values with 50-year mean return interval are obtained using ECMWF- ERA 5 global climate model snow data and a new ground snow load map for Turkey is proposed. Proposed map is validated by meteorological observations and compared with TS 498 snow load values on ground. Some design recommendations are made for PV supporting structures at SPP based on commonly observed snow damage patterns.

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...
A comparison of renewable energy systems (onshore wind, offshore wind, conventional pv) for Bozcaada Island
Şentürk, Ayşe Eylül; Oğuz, Elif; Department of Civil Engineering (2020)
Renewable energy sources have been considered as a sustainable solution for energy production without polluting the environment. Shifting from fossil fuel to renewable sources has been suggested by many scientists to decrease the global warming effects. As several renewable energy sources exist such as solar, wind, hydro-power, etc., it is important to determine the appropriate option for a selected region in terms of maximizing efficiency and power output as well as minimizing life cycle costs (LCC). There...
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...
Preliminary Study on Site Selection For Floating Hybrid Wind And Solar Energy Systems In Turkey
Yerlikaya, Nevzat Can; Çakan, Çağatay; Başara, Ilgın; Caceoğlu, Eray; Huvaj Sarıhan, Nejan (2021-09-08)
It is well-known that even though fossil fuels are the main energy resource in Turkey, use of sustainable energy resources such as wind and solar energy has been increasing in the past years and expected to continue on this trend in the next years to come. The suitable land for land-based wind turbines and photovoltaic (PV) systems could also be convenient for various other purposes, such as agriculture. This study aims to investigate the suitable sites for a combined floating wind and solar systems in the ...
MONITORING, ANALYSIS, AND SIMULATION OF PHOTOVOLTAIC HEAT ISLAND EFFECT IN TURKEY: SEKBANDEMIRLI SOLAR POWER PLANT FIELD STUDY
Demirezen, Emre; Akınoğlu, Bülent Gültekin; Özden, Talat; Department of Earth System Science (2022-1-18)
Today, solar energy conversion technologies, which are among the methods of obtaining renewable, sustainable, and clean energy, show rapid development. One of the most common technologies is Photovoltaic Solar Power Plant (PVPP), which provides electricity by direct conversion of the energy carried by the sunlight (or daylight). These power plants are socially accepted in environmentally-friendly and economical energy production. However, there are some debates about the environmental impacts of these power...
