Technical potential of rooftop solar photovoltaic for Ankara: A preliminary study

Kutlu, Elif Ceren
Cities are responsible for over two-thirds of total energy consumption due to the population's externalities. The buildings in the urban areas cause half of this energy consumption. 250 cities have 100% renewable energy target worldwide, including nineteen metropolitans such as London, Los Angeles, Tokyo, and Paris. Besides, these metropolitans aim at zero emissions in new buildings by 2030 and in the existing ones by 2050. By year of 2018, as a developing country, Turkey has a dependency ratio of 73.8 % for overall energy and 51.11% for electricity. In order to overcome problems like population-based pressure in cities and energy security, Turkey requires effective and realistic renewable energy solutions that can combat climate change. As policymakers emphasize, more decentralized solutions as city-wide and municipality-based policies, would provide faster and more effective results to reach renewable energy targets. The renewable energy potential is not the same for all cities. Although there are some rooftop technical solar PV potential studies in country-wide, one of the main motivations of this study is to focus on both building types and roof types to generalize for a city. We develop an accurate vi methodology to determine the rooftop technical PV potential reliable and applicable to every type of roofs. City of Ankara is a convenient starting point for this study due to its relatively high solar irradiance, high number of public buildings and increasing energy demand. In the study, buildings in Ankara divided into three categories: residential, public, and commercial (shopping mall). After the manual selection, the methodology is applied using a well-known Helioscope software program and suitable area constants (access factors) are determined for the three categories. Constant value method was used to generalize the constants to all buildings. The results indicate that the Mono-Si module application is the optimum one for both pitched-roof and flat-roof apartments. Bifacial modules have better results for detached houses, public buildings, and shopping malls, and the amount of energy production might be increased by row-spacing arrangement specifically to the building.


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...
Development of the algorithm of SOlAR TURnKEY: solar electricity software for Turkey
Karaveli, Abdullah Buğrahan; Akınoğlu, Bülent Gültekin; Soytaş, Uğur; Department of Earth System Science (2018)
Together with the increase in population, consumption, environmental threats, social inclusion and poverty eradication needs, natural resource corruption and price, rapid electrification of the world necessitates to meet energy demand in the most efficient, economic, environmental and social way. At this point with the sharp decrease in prices, increase in efficiency and development in technology in addition to environmental friendliness and social inclusiveness, solar electricity has gained importance when...
A data-driven approach for predicting solar energy potential of buildings in urban fabric
Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7)
Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
Literature review on BIM-based building energy performance optimization
Can, Esra; Akçamete Güngör, Aslı (İstanbul Teknik Üniversitesi; 2020-11-14)
Buildings comprise a large part of global energy consumption and make a significant contribution to overall CO2 emissions in the world. Therefore, increasing the energy efficiency of buildings becomes a priority to reduce these undesirable effects. Building energy performance assessments are complex multi-criteria problems as the energy performance is affected by many factors such as building orientation, envelope design, climate conditions, daylighting levels, and HVAC system usage schedules. This complica...
Estimation of diffuse solar irradiation and its effects on PV power plant production at METU NCC
Kavas, Genco; Taylan, Onur; Sustainable Environment and Energy Systems (2019-8)
Excess amount of greenhouse gas (GHG) emission is the main reason of global warming. Renewable energy systems are one possible way to decrease GHG emission and solar energy is one of options; however, fluctuations on solar energy production is one of the main drawbacks. Accurate estimation of energy production from a solar power plant, such as PV-based plant is important to satisfy energy demand successfully. To be able to estimate energy production in advance, solar energy incident on PV modules should be ...
