Concentrating solar power (CSP) system is a favorable application because of its potential to constantly generate large-scale electricity. Today, there are many CSP plants in the world. Therefore, the aim of this study is to analyze these systems in detail. To measure the efficiencies of these systems, a model is created and a microsystem is experimentally tested. As a result, the gas boiler modeled in this study generates a monthly amount of 3.222,317 kWh, and the collector generates a monthly amount of 1.709,8 kWh. In addition, we also analyzed the CO2 emission status, and CO2 emission reduction was calculated as 5.279,6 kg, demonstrating the environment-friendly nature of the system. This study introduces a model of CSP plant prior installation. © 2017 American Institute of Chemical Engineers Environ Prog, 36: 967-974, 2017 [ABSTRACT FROM AUTHOR]

In this study, technical, economic and environmental feasibility study of applying an integrated system including grid-connected photovoltaic panels and a forced circulation solar water heater for supplying the required electricity and hot water for a school has been carried out considering international prices of electricity and natural gas by using software. This study explored the potential waste heat recuperation of PV systems for application in green school during heating seasons. In order to make the hybrid system applicable in both heating and cooling seasons, the design details to avoid the overheating need to be scrutinized and the economic impact during the cooling seasons should be examined further. The present study have shown that a school׳s entire energy needs with renewable energy sources in Kahramanmaras climatic conditions can be solved by being able to meet the optimal planning. There is a need to support energy resources, especially when there is no sun in green house application. Green school practice does not only care about the environment but also the economic. Solar energy levels in countries such as Turkey, with good green structures can be improved. Finally, the present study showed that the full energy requirements of green school were supplied.

The next century will witness a breakthrough in terms of renewable energy sources, particularly solar energy and its derivatives. This renewable and enormous energy source offers a solution to the energy problem all over the world. One of the areas in which solar energy is used is the photovoltaic (PV) systems. The main element of this sector, however, is the pure silicon technology. Because, most efficient PV cells are made of silicon and its degree of purity is very important. The most commonly used types of these materials for PV energy conversion are thin Film, mono-crystalline and poly-crystalline silicon, which are also known as silicon modules or panels. However, performances of these modules vary by region. This study focuses on analyzing different three-type PV panels and determining the optimal panel type for Kahramanmaras with three separate PV systems, each 3-kWp and grid-connected. Besides, this study is the first research project to consider all aspects to determine optimal PV power system in the region. To this aim, three different PV systems consisting of thin film, mono-crystalline and poly-crystalline silicon panels were installed. The amount of energy generated by each system, cost analysis, annual incomes, breakeven points, installation area occupied by the system and total weights of each system are evaluated for each panel type used in the installed system and potential energy to be generated by solar energy in the region was considered. Following energy generation which lasted one year and at the end of the 30-year operation period, it is concluded that poly-crystalline silicon panels are the most optimal panel for the region because it yields the highest annual incomes and the shortest breakeven point for the investors.

Solar energy plants are popular due to their low cost, and environmental friendly and renewable nature. Germany is the leading country in the solar energy market in the world. Turkey also possesses a very high potential in terms of solar energy among European countries. The present study aims to draw attention to solar energy plants and define its applicability for these two countries. Two identical photovoltaic systems, installed in Turkey and Germany, were analyzed. First, we introduced the experimental results of two installed photovoltaic systems. Second, we numerically modelled two photovoltaic systems and processed the data with PVsyst in order to compare and verify experimental results. Numerical results display a good agreement with the experimental results, indicating that the performance of the modelling system is high, and that it can be used as a tentative photovoltaic system prior to installation. In addition, the solar energy capacities of Turkey and Germany are analyzed and discussed in detail. [ABSTRACT FROM AUTHOR]

Mountain houses abound in particularly Mediterranean region of Turkey. The development of photovoltaic (PV) solar cells has offered an opportunity to supply electricity to these houses. In addition to mountain houses, transmitter stations in remote areas, sales points by the highways, nomadic communities and farmers may also benefit from PV systems for electricity. In case of insufficient radiation, diesel generators are used for this need. This study focuses on planning, modeling and cost analysis of energy supply to a off-grid house via an optimal hybrid system. [ABSTRACT FROM AUTHOR]

Photovoltaic systems have gained a great deal of interest in the world and these studies performed on this subject have been gaining more and more importance. In order to design new PV systems that will be installed to operate in more efficient and more feasible way, it is necessary to analyze parameters like solar radiation values, the angle of incidence of the genus, temperature etc. Therefore, in this study, theoretical works have been performed for solar radiation and angle of incidence values of any location, plus an experimental study was carried out on a system tracking the sun in two axes and in a fixed system. The performed prototype is also adapted into a PV system with 4.6 kW power. Theoretical data are consistent with the data obtained from the PV system with 4.6 kW power. This study will be an important guide for the future PV power stations. [ABSTRACT FROM AUTHOR]

Shading analyzer systems are necessary for selecting the most suitable installation site to sustain enough solar power. Afterwards, changes in solar data throughout the year must be evaluated along with the identification of obstructions surrounding the installation site in order to analyze shading effects on productivity of the solar power system. In this study, the shading analysis tools are introduced briefly, and a new and different device is developed and explained to analyze shading effect of the environmental obstruction on the site on which the solar power system will be established. Thus, exposure duration of the PV panels to the sunlight can be measured effectively. The device is explained with an application on the installation area selected as a pilot site, Denizli, in Turkey. [ABSTRACT FROM AUTHOR]
