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 analyzed the efficiencies of solar PV modules with nine years of data ollected from Middle Anatolia. The most effective module is the Bifi-Mono-Si with 16.47 % as expected and the second effective module is HIT with 14.82 % efficiency. In addition to efficiencies, performance ratios are investigated and Mono-Si-1 has the highest performance ratio on average. Furthermore, we analyzed the weather corrected performance ratio of 5 modules (CIS-1 & 2, µSi/a-Si, HIT, Poly-Si-2) and the HIT module obtains the best corrected performance ratio on average. Finally, we utilized efficiencies and performances ratio values to estimate the egradation rates of solar PV modules. We found the following degradation rates for modules: 0.80 %/year for Mono-Si modules, 1.95%/year for CIS modules, 0.68 %/year for a-Si, 1.42 %/year for Poly-Si, and 1.09 %/year for HIT module. Considering all results, Mono-Si is the best option for long-term usage and development.

Long term outdoor performances of three different on-grid PV arrays in central Anatolia - An extended analysis ÖZDEN, TALAT; Akınoğlu, Bülent Gültekin; Turan, Raşit (2017-02-01) Long term outdoor testing of the PV systems at different climatic conditions or different systems under the same ambient conditions are extremely important in producing policies for the transition to renewables. The present research is the testing of three different PV systems under the same climatic conditions of central Anatolia, after four years of operation. The systems consist of a mono-Si, an a-Si thin film and a CdTe thin film arrays. Different calculation procedures of the input solar irradiation on...
Determining Photovoltaic Module Performance and Comparisons Karaveli, Abdullah Buğrahan; ÖZDEN, TALAT; Akınoğlu, Bülent Gültekin (2018-11-14) 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 estimatio...
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...
Assessment of solar data estimation models for four cities in Iran Jahani, Elham; Sadati, S. M. Sajed; Yousefzadeh, Moslem (2015-04-29) The estimated solar resources are important for designing renewable energy systems since measured data are not always available. The estimation models have been introduced in several studies. These models are mainly dependent on local meteorological data and need to be assessed for different locations and times. The current study compares the results of Angstrom's model and a neural network (NN) model developed for this study with measured data for four cities in Iran. The time resolution for the estimated ...
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) ...
