-A large number of regions are attractive for the application of renewable energy equipment, including those that are using the solar energy potential. But the volatile nature of the solar radiation flux requires specific forecasts and calculations of its intensity. Besides, installations under urban conditions are widely used in two forms: solar power plants which photovoltaic panels are placed at a certain angle to the horizon on a flat building roof; and integrated photovoltaic panels in the building construction. However, the use of such power supply systems is limited by the structural features of the roofs of buildings. That is why, it is necessary to take into account the mutual shading of the rows of photovoltaic panels and by the structural elements. This leads to limitation of the capacity of the installation and to shortage of the utilization of the solar energy technical potential for the installation placement. Integrating photovoltaic panels into the building structure, a decrease in the amount of generated electric energy are associated with a deviation from their optimal spatial orientation, which leads to reduction in the coefficient of the used installed capacity of electrical equipment, that is, the low efficiency of conversion of solar energy into electrical energy. That is why, an accurate assessment of the solar potential of renewable energy sources, taking into account the design features of urban development, allows one to justify the parameters of the generating unit at a design stage, and to predict its operating mode and to evaluate technical and economic efficiency.Keywords-solar energy, tilt angle of the receiving surface, orientation by the sides of the world

“…First of all, it is worth noting that the overall number of papers on this topic is rather small. At the same time, existing research is mostly devoted to the macro-assessment of RES potential and the overview of its development in Russia [28][29][30] or to the assessment of natural potential of specific renewable resources [29,31]. For instance, study by Molodtsov [28] provides an interesting insight on where each type of renewable may be the most attractive, but it is of conceptual nature and may not be used as a ground for particular actions.…”

“…However, this paper is largely devoted to the assessment of the overall attractiveness of various RES and is not case-specific. A study by Daus et al [31] provides a detailed assessment of solar potential in Southern Federal District of Russia but does not imply concrete actions based on the results. At the same time, all of the mentioned papers do not devote enough attention to the demand side of the RES potential.…”

The paper is devoted to the assessment of the prospects of implementing clean energy sources in Russia, where the current energy policy goal is to increase the role of renewable and clean energy sources. The research is based on data from the Krasnoyarsk Region as one of the largest territories but also as a representative model of Russia. The aim of the study is to identify where and which renewable energy source (solar, wind, hydro and nuclear) has the highest potential. The novelty of our research lies in its holistic nature: authors consider both geographical and technical potential for renewable energy sources development as well as prospective demand for such resources, while previous research is mostly focused on specific aspects of renewable energy development. We also consider the level of air pollution as an important factor for the development of renewable energy sources. The results of the study show that there is a strong potential for clean energy sources in the Krasnoyarsk Region. The resulting matrix identifies the potential of energy sources across all the municipal entities and also indicates whether the source of energy is primary or supplemental and where several sources may be implemented in cooperation.

Abstract. High anthropogenic load on the environment due to the intensive development of energy sector worldwide is forcing to seek environmentally friendly available sources of energy, for example, to utilize solar energy. To enhance the economic and environmental attractiveness of projects for the constructing solar power facilities there must be achieved maximum realization of existing solar energy potential and defined optimal placement of the receiving surface of photovoltaic panels regarding the Sun motion. The purpose of the article is to design software program of determining the optimal inclination angle of the receiving surface, taking into account solar radiation intensity falling on the differently oriented surfaces during the day to increase the level of utilizing solar energy potential in a given period of time, to reduce the computation time, increasing the effectiveness of the decisions. The proposed computer program can be used as a structural element of designing systems of microgrids, engineering facilities using solar energy modules, stand-alone and network, roof or ground-based solar power plants.
