This research addresses the impact of the building integrated photovoltaic (BIPV) solutions on the performance of a residential building with the area of 2247 m2 at different regions of Coastal Anatolia. Three cities are chosen with respect to their solar heat gain as the lowest, highest and average. Hourly performances are calculated using the DOE software of Energyplus and installed peak PV power calculated as 84.2 kW. Our preliminary results showed that the annual heating and cooling energy consumption for the three locations vary between 1.44 kWh/m2-9.12 kWh/m2 and 22.2 kWh/m2-56.9 kWh/m2, respectively. The cooling demand is much higher than the heating demand for these coastal locations of Anatolia (as expected). The maximum use of the three cities is 56.9 kWh/m2 and according to results this load can be easily supplied by an 84.2 kWp PV. As these are preliminary results they can be treated within margins of ± 20 kW depending on the orientation of the building facades and the type of the solar cells.

Energy supply to a regional grid for water pumping systems is sometimes difficult. But utilization of solar energy systems may meet energy requirements for such pumping systems. A pumping station covering an area of 16290 m2 is studied in this research. The station is located in Tabriz city, Iran which has an annual solar insolation of 1884 kWh/m2. The energy need for the pumping station is planned to be provided by an 800 kW photovoltaic (PV) power plant which uses one-axis sun tracker to increase the energy generation. The simulations are carried out using both PVSYST and HOMER software. The proposed PV power plant design has a performance ratio of 83.7%, and the electrical losses and geographic location of the designed area are considered along with the hardware equipment and environmental profits. Simulation results demonstrate that the land and climatic conditions –as the main factors- are strongly suggestible for the implementation and construction of the aforementioned PV power plant that reduces system losses while around 20% emission reduction for SO2, NOX, and CO2 can be achieved.

Ankara (latitude: around 40°N) is in Central Anatolia and the climate is dry continental. Due to the rapid transition to renewable energy policies of Turkey it is now a must to complete truthful feasibility analyses for solar power systems countrywide. Long term performance and degradation analyses have been carried out by the authors for three different arrays and many research results appearing in the literature are summarized. Present research analyzes the outdoor testing results of two PV modules monthly data. One of the modules has multi crystalline silicon (Poly-Si) cells and the other is thin film silicon (amorphous Si / microcrystalline Si tandem structure – $mathbf{a}-mathbf{Si}/boldsymbol{mu} mathbf{c}-mathbf{Si}$) cells. The results showed that in five years the average yearly efficiency decreases from 14% to 11% for Poly-Si (14.72% is the nameplate Standard Test Condition (STC) efficiency) and from 8% to 6% for thin film modules (9.15% is STC efficiency). Our calculations are based on measured solar global-horizontal irradiance from which we calculated plane-of-array irradiation using an anisotropic sky model. We present the details of these analyses and degradation rates for the two types of modules to be used in long term feasibility analyses.

The understanding and quantifying of photovoltaic (PV) modules degradation is important to ensure their lifetime at harsh conditions. A test campaign on several pc-Si PV modules at semi-arid climate has been conducted after 3 years of outdoor exposure. As a result, 58,5% of modules showed snail trails formation. This defect has been observed increasingly during last decade whereas; the performance variation functions of snail trials have not yet been thoroughly investigated. In this work, the power drop of PV modules affected by this defect after 3 years of operating was performed. Besides, electrical parameter degradation is quantified by measuring the modules performance parameters under standard test conditions as a function of field exposure time. The degradation rate (Rd) for each PV modules have been analytically calculated with discrete data. Results show that the rate of power drop of studied PV modules could reaches 3%/years. EL imaging technic also conducted and demonstrates that the snail trails defect occurs at the micro cracks and can be considered as a simple way to its detection. In addition, 0,12%/y of yearly power drop may be due to both snail trails and cracks defects.

Multiple Exciton Generation (MEG) concept has been reported to be one of the most effective method to exceed 33% Shockley–Queisser theoretical limit. According to the recent reports, 2-D nanostructures are better alternative for MEG compared to dots. We therefore report optimized lead selenide nanorod (PbSe NRs) synthesis conditions, known to have the highest MEG yield, to reach the best performing synthesis protocol and investigate the stability of NRs against air and moisture. We found that reaction parameters such as temperature profile, oleic acid to lead ratio (OA/Pb) and the presence of catalyst have significant effects on the optical and morphological properties of the NRs. The transformation of dots to rods starts when the OA/Pb ratio increases from 1.5 to 3.5 together with an increase in both branching and length of the rods. Utilizing catalyst to improve the NR yield requires careful optimization as the unoptimized concentration of catalyst leads to the breakage of rods to dots as the reaction proceeds. We also report high sensitivity of PbSe NRs towards oxidation. Surface, being the main suspect of the degradation, plays a crucial role as oxidation starts from the surface and proceeds towards the core.

Renewable energy resources such as solar resources are suitable alternatives for the use of fossil fuels as they are abundant, can be harnessed in affordable ways and are considered environmentally friendly. However, renewable energy resources fluctuate with time which decreases the matching between the energy produced by the renewable energy system and the demand and also decreases the reliability of the power supply. There are several potential ways to increase the matching and reliability of renewable energy systems such as the hybridization of renewable energy resources and the integration of energy storage. A techno-economic analysis of different configurations of Photovoltaic, Hydrogen Fuel Cell (HFC) and Pumped Hydro Storage (PHS) is carried out where Middle East Technical University Northern Cyprus Campus (METU NCC) is the case study. The optimal configurations of the PV system with different energy storage system configurations for the university are found based on maximizing the renewable energy (RES) fraction with Levelized Cost of Electricity (LCOE) equals to the grid tariff. However, the objective of the optimization becomes the maximization of the RES fraction with the minimum LCOE if there is no a feasible configuration. The results show that the integration of HFC and PHS system with the PV system increases the RES fraction and the demand-supply fraction from 36.2% to 45.4% and from 23.9% to 35.1%, respectively. The proposed system consists of 2.57 MW PV, 1.16 MWh HFC and 4.14 MWh PHS where such a system has LCOE of 0.181 USD/kWh.

Ankara is in the Central Anatolia region of Turkey where the climate is dry-continental with an annual solar insolation of around 1750 kWh/m2. In the transition to renewable energy, detailed analyses are required to ensure effective and economic utilization of the available solar resource. An essential part of these analyses is to calculate expected energy yield. For photovoltaic (PV) systems, this includes the effect of temperature on the PV efficiency, which determines the power yield of the PV modules. In this study, a first-principles thermal modeling approach is improved by adding the speed and direction of wind across the PV module into a forced convection term as well as including the temperature dependency of the module conversion efficiency. The analytical model is based on the principle of conservation of energy and uses meteorological data that are readily available from most state meteorological services. The mathematical analysis is suitable to predict the performance of a proposed PV installation without the time and expense of installing and monitoring a pilot system. The mathematical model is compared against measured data from the METU-GUNAM Outdoor Test Facility in Ankara to validate the methodology. Preliminary analyses showed that the model performs well especially during sunrise and sunsets shoulders of the diurnal cycle with a deviation of only a few W/m2 for the electrical power yield and about 2°C for the module temperature. However, these deviations could become as large as 12 W/m2 and 8°C at solar noon which suggests that the model still requires further improvement. In general, this error was found to be less that obtained by using basic explicit correlation methods and offers the advantage that it can be used for other geographical environments for which insolation and meteorological data is available without needing to construct a test-site.

Nowadays, the investments in large-scale photovoltaic power projects is increasing around the world and more especially in the MENA region. To encourage investors to install more PV capacities, it's important to provide guaranties on the benefits in term of production especially in harsh and semi-arid climates. For this reason, modeling of photovoltaic performance in such conditions is required to predict accurately the plants energy yield. The aim of this study is to adapt a non-linear empirical model to simulate the photovoltaic production under semi-arid climate. The new developed model represents the output power of the PV module as a function of in-plane irradiance and ambient temperature, and a number of semi-empirical coefficients determined by fitting the outdoor measured data. The model has been validated using one year of high accurate measured data at ground level of a polycrystalline module at Green Energy Park research facility. Results of this study show that the proposed model is a good approach to predict the output photovoltaic power under semi-arid climate with an hourly nRMSE of 3.1% in comparison to ground measurements.

The photovoltaic (PV) module has several models in the literature, the popular ones are the single and double diode models. As well as, these two models possesses five and seven parameters respectively, therefore these parameters must be defined. In this paper, the flower algorithm is used to extract the optimal parameters values of both models. The purpose of this algorithm is to find the optimal reproduction of the plants species by the transfer of pollen which is considered as an optimization process. Experimental validation was carried out by comparing the simulation results with measured data, this data represents a measurement campaign of I-V curves for the three most used technologies in the photovoltaic market in order to test and validate the both models.
