The use of alternative energy sources, in particular solar energy, has gained rapid growth in recent years. This trend is prompting manufacturers of equipment for solar power plants to increase production volumes. At the same time, the question arises of the disposal of used modules, because each material has its service life. According to technical specifications, the average life of solar modules and batteries is 25-30 years. Decommissioning may occur earlier than this time due to the following reasons – moral and physical deterioration, mechanical damage, replacement of obsolete equipment with new, modernization of solar power plants. Already in 2030, it will be necessary to replace the solar modules installed in 2000. Therefore, there are acute questions not only regarding the development of technologies for processing waste equipment from solar power plants but also organizational and economic methods. This article discusses the main problems that arise during the utilization and recycling of solar modules, analyzes the experience of countries in resolving these issues. After all, the use of renewable energy sources should minimize the negative impact on the environment from energy production at all stages – from the production of equipment for a power plant to the disposal and recycling of this equipment.

Solar energy is considered to be one of most promising renewable energy sources because of its availability and cleanliness. The phenomenon of dust deposition on solar mirrors greatly reduces the power generation of solar power plants. In this work, the motion behaviors and deposition mechanics of dust particles are analyzed by the discrete element method (DEM). The effects of environmental and solar mirror conditions and particle self-factors on dust deposition weight are systematically studied here. The research results show that dust particles, after particle collision, immediately adhere to the mirror or rebound and finally flow away from the mirror, or they otherwise may remain stationary after making some relative motion. Alternatively, they may glide for some distance and finally come to rest on the mirror or leave from the system. Different motion behaviors after particle collision depend on different leading forces. Here, the leading forces are the liquid bridge force (Fc) and the contact force (Fb). When the leading forces are Fc, or Fc, and Fb, the dust particles will be deposited on the solar mirror. Besides, the force Fc cannot be negligible when studying the motion processes of dust particles. The dust deposition weight on solar mirrors can be controlled by altering the environmental and solar mirror conditions, and particle self-factors. In essence, dust deposition weight on solar mirrors decreases when decreasing the leading force Fc or increasing the leading force Fb. The research results give theoretical guidance for the prevention and removal of dust deposition on solar mirrors.

The Impact

The development of rural electrification is aimed at distributed energy, i.e. availability of autonomous sources of electricity and heat generation. Generation sources can use coal, fuel oil, gas, local and alternative energy sources as fuel and energy resources. This causes additional emissions of pollutants. Prediction of negative impact on the environment depends on the quantity and quality of emissions during the operation of various types of installations that generate electric and thermal energy. The purpose of the study is to select and substantiate the most attractive method for predicting the impact on the environment of generating sources in agricultural production. The widespread introduction of distributed energy using local and renewable energy sources will significantly reduce emissions of pollutants due to a decrease in energy intensity, matching the required load with the capacity of generation sources, using the most energy efficient sources, and widespread introduction of renewable energy sources. In this regard, it is advisable to forecast the impacts by the scenario method considering the implementation of the proposed distributed power supply system. The implementation of measures developed considering the analysis of the forecast of the negative impact on the environment of generating plants in agricultural enterprises will reduce the negative impact on the environment by introducing energy-efficient technologies into the energy balance of the enterprise, as well as increase production by up to 20% and increase sustainability. rural areas.

This article provides a brief overview of the state of solar energy in the world. Disadvantages of fossil energy sources are discussed. Low efficiency is considered the main disadvantage of renewable energy sources. A possible way to improve efficiency of solar modules through the use of solar tracking systems (STS) is analyzed. STS is a special device with two drives for horizontal and vertical guidance to ensure that solar modules face the highest light flux source and thereby increase generation of electricity using a special algorithm. The theoretical increase in production for systems under ideal conditions is calculated; working values thereof are given. The disadvantages of the considered type of renewable energy generators are listed. The calculation of wind loads on the STS was carried out according to the presented method. Examples of destruction of solar power plants by natural disasters are given. A new type of solar trackers with a self-deploying system is proposed; these can protect the installation from unfavorable weather conditions. We analyzed accuracy of the positioning algorithm developed for this device. The conclusion contains possible ways of using the installation, its disadvantages, as well as plans for future research.

Abstract The features of agricultural energy in the Krasnodar Territory are considered and two main problems are identified: the shortage of generating capacities and the remoteness of low-power consumers from centralized networks, for the solution of which renewable energy sources, including solar energy, can be used. The use of solar power plants at the enterprises of the agro-industrial complex of the region has been substantiated. The importance of automating the process of assessing the territory suitable for the placement of solar power facilities and the features of its implementation are substantiated. Criteria have been obtained that influence the choice of the optimal option for placing solar power facilities, based on the methodology for calculating the power and the amount of generated energy. The features of calculating the matrix of spatial characteristics for renewable energy facilities in the Krasnodar Territory are shown. An algorithm for creating a matrix of spatial data and an algorithm for choosing the optimal option for placing solar power plants are presented. The use of a high-level programming language Python is proposed to implement the created algorithm. The conclusion is made about the possibility of automating the process of assessing the efficiency of the placement of solar power plants in the Krasnodar Territory using modern computing technology in the format of a geoformation application developed in the Python programming language.

In the last few years, the world has been turning to the exploitation of renewable energy sources due to increased awareness of environmental protection and increased consumption of fossil fuels. In this research, by applying geographic information systems and integrating them with multi-criteria decision making methods, an area suitable for the construction and exploitation of renewable energy sources is determined. The research uses not only climate, spatial, environmental, and geomorphological parameters but also socioeconomic parameters, population, unemployment, and number of tourist nights as well as electricity consumption. By applying spatial analysis, rasters of all parameters were created using GRASS GIS software. Using the analytic hierarchy process, the calculated rasters are assigned with weight coefficients, and the sum of all those rasters gives the final raster of optimal locations for the construction of solar power plants in Croatia. To test the accuracy of the obtained results, sensitivity analysis was performed using different weight coefficients of the parameters. From the sensitivity analysis results, as well as a histogram and statistical indicators of the three rasters, it is apparent that raster F1 gives the best results. The most decisive parameters in determining the optimal solar plant locations that result from this research are GHI, land cover, and distance to the electricity network.

The Future

The future of European energy is moving towards a single European electricity market and an increasing share of renewables in the overall production mix. After the expiration of governmental incentive measures, power plants based on renewable energy sources will enter the liberalized market, where electricity prices will largely depend on the production of renewable energy sources. In order to achieve the maximum possible profit of the power plant under such conditions, it is necessary to consider the possibility of investing in solutions that are less represented today, but with the prospect of being more profitable in the future. Such a solution is a solar power plant consisting of vertically placed bifacial modules whose active surfaces are oriented in the east-west direction. This configuration of the power plant can achieve higher production in periods of high prices, and thus higher profits from the sale of electricity. On the other hand, such a solution is more expensive than a standard solar power plant with monofacial modules. In this paper, a comparison of return on investment in a bifacial power plant and a monofacial power plant with existing and prospective market conditions is performed. PVsyst software was used to analyze the solar potential and production profiles of photovoltaic power plants. The influence of solar power plant production on the price of electricity was investigated on the example of Germany. Based on this research, a prognostic model of the daily price diagram on the unified European market until 2040 was formed which served for the analysis of the profitability of investments in the two considered variants of the solar power plant realization.

Additional Fuel

One of the most promising areas in the development of the electric power industry is generally regarded to lie in expanding the share of renewable energy sources (RES) in the electric energy balance of power systems in the form of wind and solar power plants (WPP and SPP), the saving of organic fuel (coal, gas, fuel oil) and the reduction of environmentally harmful emissions into the atmosphere considered to be their most important advantages. However, the impact of RES on the controllability of the modes of operation of electric power systems and on the reliability of the IPS operation remains quite unexplored.Currently, the global energy industry uses 318 million kW of WPP and about 142.4 million kW of SPP, of which the major West European countries account for about 227 million kW, or 49.3%. On average, wind and solar power plants account for almost 30% of the total generating capacity in Western Europe, with Denmark having the largest share of WPP (47%) and Germany having the highest share of SPP (18.6%). However, an uncontrolled growth in the share of WPP and SPP in the structure of generating capacities of power systems begins to manifest itself in a sharp decline in the reliability of the power industry due to the fact that a number of negative properties of WPP and SPP have not been taken into account (at least, to a sufficient extent), which manifested themselves in practice in a system accident in the UK power system that occurred on August 09, 2019, when, as a result of an "ordinary" short circuit, a system accident occurred, with up to 1.1 million consumers with a total load of 1690 MW disconnected from the power supply system for a period of 15 to 45 minutes. This is estimated to have resulted in economic losses for consumers amounting to 12.3–15.0 million USD.The reason for this is that the high sensitivity of WPP, SPP, CCGT and gas piston units to voltage and frequency drops is not properly considered in conditions of insufficient capacity of the rotating (mobile) generation reserve. Damage can be prevented by increasing the rotating reserve within the available reserve of the power system, which will require an increase in funds for maintaining the same due to additional fuel consumption. The ratio of reduction of probable damage to consumers and the cost of additional fuel consumption for maintenance of a required rotating reserve in the power system allows to economically substantiate the strategy and scale of introduction of renewable energy sources to the power industry.

Main problems of traditional and renewable energy development in the ecological context are considered in the article. The experience of developed industrial states in solving environmental problems and the work carried out in this direction in our country is presented. Today, many countries have a number of renewable energy targets: reducing greenhouse gas emissions, increasing the share of renewable energy sources in final energy consumption and meeting the growing demand for energy. Thus, the use of such sources of electricity as wind turbines, solar power plants or small hydroelectric power plants in the minimum configuration, which includes only an energy converter (wind turbine with a PVC generator or a hydraulic turbine with a generator) and a device for converting electric current parameters to standard values (inverter, stabilizer), not in able to provide high-quality and guaranteed constant power supply to the consumer.
