AbstractRenewable energy sources have been placed as the key to facilitating to provide source of electricity generation. Solar power is one of the most preferable one among renewable energy sources due to the easy to generate in suitable environment. However, there are concerns with the location of solar power plants installation which causes low efficiency and ineffective use. Hence, determining the location for the usage of solar power sources is critical to mitigating those concerns. In addition, Turkey has been focused on investments on sustainable renewable energy sources and there are few studies which work on cities to reveal potential sources. In this study, GIS and intuitionistic fuzzy set based multi-criteria decision-making method is proposed for determining the most suitable areas for solar energy power plant potential site selection in Erzurum province, Turkey. Firstly, a solar energy power plant potential site selection map is made using a GIS program along with considering ecological risks and ecological criteria. Secondly, 20 districts of Erzurum are investigated in terms of 10 criteria (slope, aspect, solar irradiation, land use, wind speed, air temperature, air pressure, air humidity, land surface temperature and transmission line) using intuitionistic fuzzy sets. In these parameters the first time we looked the land use surface. The land use surface is affected the efficiency of the solar power plant. Finally, the comparisons of two methods are done to check consistency of results obtained. The results indicate that both approaches achieve same areas as the most suitable locations for solar power plants installations for Erzurum province in Turkey. The aim of this work is first to investigate possible locations for solar power plant installation using a mapping method, GIS, and then, Intuitionistic Fuzzy is applied to the problem to obtain optimum areas for solar energy. Also, more accurate results are provided comparing results of two methods, GIS and Intuitionistic Fuzzy. The results expose that 25,065.3 km2 for solar power plant suitable for solar power plan installation.

The article aims to study current trends in the use of solar energy in Ukraine and the world as one of the main directions of decarbonization of the national economy. The authors systematize the prospects, advantages and disadvantages of the development of renewable energy sources. They conducted a comparative analysis of the "efficiency" of solar energy in some countries and Ukraine. The authors determined that the leading position in terms of the share of energy consumed from renewable sources is occupied by countries with developed economies due to the availability of effective motivational mechanisms. From the experience of EU countries, the authors concluded that renewable energy sources form a prerequisite for obtaining additional socio-economic and environmental effects. In the presence of favorable market conditions, renewable energy sources can increase the level of energy security in the country and its energy independence. The article analyzes the legislation of Ukraine on stimulating the development of alternative energy. The authors proposed two opposed ways of further developing solar energy in Ukraine. In particular, the country can implement methods of using alternative energy, which developed countries have successfully implemented. Another area involves increasing research and innovation in implementing, using, maintaining, and utilizing energy-generating devices from alternative energy sources. Despite the polarity of the proposed directions for further development of renewable energy, in both cases, the state policy on attracting investment and promoting the use of energy from alternative energy sources is crucial. In addition, the authors noted the benefits for society from the development and implementation of alternative energy sources. The scaling up and promotion of energy production technologies from alternative sources can reduce carbon emissions, which has been an urgent problem globally.

The decrease in fossil-based energy sources and increasing environmental problems increase the tendency to renewable energy sources day by day. The potential of renewable energy sources differs according to the region where the energy will be produced. For this reason, it is crucial to conduct a good feasibility study that deals with the selected systems from a technical and economic point of view before making an investment decision on energy conversion systems based on renewable energy sources. In this study, the most suitable equipment and capacities were investigated by examining the techno-economic analysis of a hybrid system created with wind-solar renewable energies for a detached house, which is considered off-grid, in a rural area of Tekirdağ province (40o58.7ı N, 27o30.7ı E). Investigations were carried out using the HOMER Pro (Hybrid Optimization Model for Electric Renewable) program. The wind and solar energy potential of Tekirdağ province were obtained from the NASA renewable energy resources database added to the HOMER Pro program. The daily electricity requirement of the sample house was chosen as 11.27 kWh, and the current peak electrical load was chosen as 2.39 kW. A wind turbine is connected to the AC busbars, solar collectors and battery group connected to the DC busbars, and a converter that converts energy between AC and DC busbars in the energy conversion system. In order to determine the optimum capacities of the system elements, 27486 different simulations were performed by HOMER Pro. The selection of the most suitable system among these was determined according to the lowest net present cost (NPC) value. In addition, the energy production capacities that will occur in the case of different wind speeds were also investigated. Accordingly, the system to be installed with a solar panel with a capacity of 6.25 kW, PV-MPPT with a capacity of 1 kW, 2 wind turbines with a capacity of 1 kW, 8 Lithium-ion batteries with a capacity of 6V-167 Ah, and a converter with a capacity of 2.5 kW has been determined will generate electrical energy of 5433 kWh per year. In addition, it has been determined that 61.8% of this produced energy will be obtained from solar energy and 38.2% from wind energy, and the simple payback period of the investment will be 14 years. It is thought that this study will provide valuable information to researchers and investors.

Energy use always increases, especially fossil energy. Through the National Energy Policy, the government continues to strive to increase the role of new and renewable energy sources so as to reduce dependence on fossil energy. Solar power generation is a type of renewable energy generator that capable to convert solar energy to electric energy. The main components of solar power generatios are batteries, solar panels, charger controllers, and inverters.  Solar power generations technology itself is always being developed, such as automatic monitoring and sun tracking systems designed to improve system performance. One of the applications of solar power generations is in the household sector. In this sector consumes 49% of the national electricity energy in 2018. This type of generator is categorized as a roof solar power generations. Based on existing data, there were 1400  roof solar power generations users in September 2019. The development of solar energy utilization for the household sector is very appropriate because it can help achieve renewable energy about 23% in 2025 and 31% in 2050 in the national energy mix.
