Knowing electricity production potential of a photovoltaic (PV) system prior to installation is very beneficial for the investor to see the feasibility of the investment. There are three procedures that can be followed to calculate the potential electricity production of any system under different conditions. These are installation of sample systems and gathering data over time, the use of some databases/software programs to reach the performances and developing new model/methodology to make these estimations. It is obvious that installation of PV systems everywhere is neither technically nor economically conceivable. On the other hand, global software programs may not reflect local conditions to calculations. Consequently, there is a need to develop methodology that is able to derive location specific equations and coefficients and make accurate estimations. Its accuracy can be controlled by validating the results for some locations with the measured values from already installed PV power plants (PV PP). So, in this study we initially develop a methodology to calculate efficiency and electricity production performance of some modules for Ankara and compare the results with the measured values owing to the system installed on the roof of the Middle East Technical University Solar Energy Research Center (METU GUNAM) in Ankara/Turkey. The methodology initially calculates solar irradiation falling on the modules that is the input. Then the performance of the module is calculated by using developed methodology. There are also some online software programs to calculate the performances, such as EU PVGIS and PV WATTS. We analyzed and used these software programs and compare their results with the results of newly developed methodology. As proven through mean-bias error (MBE), root-mean-square error (RMSE) and mean absolute error (MAE) statistical comparison methods, the methodology of this study has given the most accurate results.

Technical potential of rooftop solar photovoltaic for Ankara
Kutlu, Elif Ceren; Durusoy, Beyza; Ozden, Talat; Akınoğlu, Bülent Gültekin (2022-02-01)
Turkey, which has immense solar potential, has recently shifted towards solar energy and new renewable energy deployment regulations, including implementation and commercializing rooftop PV technologies. Thus, these require a detailed assessment to determine the power source's capability and convince the policymakers. To the authors' best knowledge, there is no available data or a city-based study for the rooftop PV potential in Turkey. Here, we present the first city-based rooftop PV potential study in Ank...
Optimal sizing of stand-alone photovoltaic systems in residential buildings
Okoye, Chiemeka Onyeka; Solyali, Oguz (2017-05-01)
Solar photovoltaic (PV) system is one of the matured solar-to-electricity conversion technologies with a great potential for residential applications. For wider adoption of PV systems, there is a need for an accurate sizing and economic assessment tool to inform decision makers. In this study, we propose a new optimization model based on integer programming for the adoption of stand-alone PV systems in the residential sector. The proposed model not only determines the optimal number of PV modules and batter...
Analytical Modelling, Simulation and Comparative Study of Multi-Junction Solar Cells Efficiency
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...
LONG TERM PERFORMANCE AND DEGRADATION RATES OF PV MODULES IN CENTRAL ANATOLIA
Cantürk, Zeynep; Akınoğlu, Bülent Gültekin; Özden, Talat; Department of Physics (2021-9-09)
Outdoor tests of photovoltaic modules are crucial for the market, and technological development. It is vital for manufacturers and researchers to conduct tests not only in the long term but also in different climatic conditions. In this thesis, 12 modules are tested in Middle Anatolia climate conditions for nine years in three different module groups, which are mono-crystalline (Mono-Si-1 & 2 & 3, Bifi-Mono-Si, HIT), polycrystalline (Poly-Si-1 & 2), and thin films (CIS-1 & 2, CIGS-1 & 2, µSi/a-Si). We analy...
Daily and Monthly Module Temperature Variation for 9 Different Modules
Özden, Talat ; Tolgay, Doga; Akınoğlu, Bülent Gültekin (2018-11-14)
One of the main parameter affecting the efficiency of PV modules is the module temperature. In this respect, outdoor testing of modules is very important to determine the temperature dependent performances and degradation rates. In this work, we analyzed the module temperatures of 9 different modules tested in the outdoor testing facility of METU-GUNAM, Ankara (latitude similar to 40 degrees N, in Central Anatolia and the climate is dry continental). The tested module types are two CIS (identical), one mu c...
