Due to the increasingly dynamic climate change and the increase in the number of people in cities, renewable energy sources (RES) are contributing to a more rational use of energy. Given the importance that the use of RES in housing directly brings in terms of financial savings and reduction of CO2 emissions, the paper examines the possibility of using RES in multi-family housing from the aspect of solar energy collection and conversion respectively implementation of photovoltaic panels and electricity generation. In multi-family housing, the problem of sustainability and implementation of RES is a complex task, primarily due to the existing ways of using space and ownership, which is multi-layered, but also the need for the active involvement of the entire housing community in deci-sion-making and initiatives. The research analyzes the advantages and disadvantages of installing solar panels on the rooftops and facades of buildings, and within the common open spaces in the block, by installing solar lamps, solar power for electric vehicles, solar chargers, etc. The examina-tion of the possibilities for using solar energy was conducted on the example of the residential Block 29 in New Belgrade, using urban analysis supported by appropriate data on solar radiation for the analyzed area and Skelion software for a numerical and graphical illustration of the amount of ener-gy that can be obtained by installing photovoltaic solar panels. The paper considers two different scenarios: when panels are installed on the roofs of buildings and when they are installed in open spaces, analyzing the potential of each and the prerequisites for their implementation in practice. The results aim to compare the quantities of electricity obtained by calculation for two different scenarios.

This paper is dedicated to the research of solar energy issues, namely to increase the efficiency of solar panels and to compare the performance of solar panels in different configurations. The author researches and compares the performance of solar panels with and without trackers. The sun is an inexhaustible source of energy that mankind has yet to appreciate. Solar energy is the kinetic energy of radiation (mainly light) generated by thermonuclear reactions in the bowels of the sun. Solar energy is one such alternative, the neglect of which will in the near future lead to catastrophic consequences for humanity. Solar energy is a progressive method of obtaining various types of energy through solar radiation. Solar energy is one of the most promising and dynamic renewable energy sources (RES). Each year, the increase in commissioned capacity is approximately 40-50%. In the last fifteen years alone, the proportion of solar electricity in the world has exceeded the 5% mark. To increase the efficiency of solar panels, designers and engineers are developing new devices and devices, one of which is a solar tracker. A solar tracker is a device that allows you to control the movement of the sun across the sky, as well as move the solar panel to the position where the absorption of sunlight is most effective. After the conducted experiment , calculations an comparison we can see the next results. Without the solar tracker our panel generated maximum power in 2.4 Watt. After the solar tracking system integration, our panel generated almost 20 (19.8) Watt of power! After this comparison we can tell that the generated power increase in 8.25 Watts. We can also admit that the amount of generated power depends on light intensity. But solar panels are the most effective when the solar beam falls perpendicular to solar cell and solar panel is at an angle of 75 – 85 degrees

The provisions in the European and Polish law oblige to increase the use of energy obtained from renewable energy sources. In order to meet these demands, it is necessary to take into account the singlefamily housing sector that has a significant energy potential. Among the unconventional heat sources that have gained the highest popularity, it is worthy to note installations using solar energy for instance to prepare DHW (domestic hot water) or be used in buildings’ heating. It is also worth mentioning that this type of technical solutions can be successfully used as well in new as modernized old residential buildings. Our paper discusses the problems associated with planning of solar installations with flat and vacuum solar collectors mounted on the roofs of the single-family buildings. During the analysis we used GIS&T technology, multi-criteria decision support as well as detailed spatial data obtained by modern remote sensing techniques including airborne laser scanning. The proposed methodology and tools were used on the example of the selected part of a single-family housing estate located in Bialystok. The research focused on issues of the multi-criteria assessment of the assembly of use of roofs for solar collectors, including data on a solar potential, exposure, slope, surface and roofs’ shape. Additionally, we took into account roof zones on being in a shadow caused by roof elements, roof infrastructure and high vegetation. Based on the simulation results we analyzed possibility of plate and tube solar collectors’ application that would provide warm water for 1-4 habitants of houses. The results of our research showed high utility of the proposed methods in the field of spatial and economic assessment of the use of solar collectors in the single-family housing sector.

The use of solar energy systems among renewable energy sources is gaining importance day by day. Photovoltaic systems have a special importance among solar energy systems. Although the incident light flux increases the electrical energy produced in the solar panels, the increase in temperature caused by the radiation reduces the efficiency of the solar panels. Important methods are being studied in order to increase this falling efficiency. Dynamic cooling systems are one of the important methods used in this field. In this study, a dynamic cooling mechanism was designed and developed for a double-faced photovoltaic power generation system. From this point, it was concluded that temperature is one of the important factors affecting the efficiency of solar panels.

Study Results

The article is devoted to finding ways to improve the efficiency of using solar panels. In the mainstream of increasing the economic efficiency of solar stations' operation, methods of reducing the cost of generating electricity based on solar energy are considered. The purpose of the article is to study ways of more efficient use of solar energy and compare the types of installation of photovoltaic converters. The study's main focus is on solar tracking systems, which give the best price/efficiency ratio for solar stations. In particular, the economic feasibility of using a biaxial tracking system for solar panels has been investigated. The advantages and disadvantages of this approach are considered. The energy potential of solar radiation under terrestrial conditions is analyzed. A table of dependences of the angle of motion of the Sun in time for one light day for the conditions of the Sumy region was built. The maximum value of the intensity of solar radiation per year per 1 m2 is calculated. The graph of the average monthly electricity production was built. In the course of the work, an experiment was set up, within the framework of which four options for photoelectric converters' placement were calculated: with automatic guidance to the Sun; inclined type; vertical type; with a fixed angle. It has been established that for the city of Sumy a two-axis orientation system is most effective. According to the results of processing the experimental data, the system with the tracker provides almost 24% more power generation than the stationary installation option (fixed angle) of the photoelectric converter module. Energy organizations and enterprises can use the study results, authorities and other stakeholders in the field of alternative energy.
