The urgency of the work is due to the feasibility of increasing the energy efficiency of solar power plants through the use of solar energy concentrators. Ways to improve the energy efficiency of solar panels using a sys-tem of directional mirrors, flat Fresnel lenses, spherical concentrators and trackers have been investigated. It is established that the most optimal way to improve the energy efficiency of solar panels is to use inexpensive track-ers with a simple design. The analysis of known types of solar panels, which differ in materials from which their elements are made, and the coefficients of efficiency – dependence of energy produced by a photocell on the intensity of solar radiation per unit of its surface has been carried out, and the type of solar panels by the criterion “price-quality” has been selected. A tracker design has been developed to track the angle of inclination of solar panels to increase efficiency. The electricity generated by the proposed solar power plant was calculated using an online calculator. It is projected to reduce losses when generating electricity for a given power plant due to the use of a tracker compared to a fixed power system, with the same number of solar panels. In order to reduce the cost of the tracker, it is suggested to orientate it to the south at once, and to change the inclination angles twice a year (in early April and late August). The energy efficiency of the power plant is calculated in two stages. At the first stage the amount of electricity from solar panels per year when adjusting only the angle of inclination of the panels to the south is calculated. At the second stage energy efficiency of the power plant is calculated taking into account the increase of energy efficiency of the solar power plant when using the tracker system. The calculated electricity generation of the proposed solar power plant with tracker confirmed the efficiency and feasibility of using the designed tracker system. The application of the designed tracker system allows to increase the energy efficiency of solar panels by an average of 25%.

The paper provides basic information on the 2 kWp PV solar power plant with monocrystalline silicon solar modules installed on the roof of the Faculty of Sciences and Mathematics (FSM), University of Nis, and the equipment for the investigation of its energy efficiency depending on the real climate conditions. Furthermore, results of the simulation and experimental determination of the energy efficiency of the PV solar power plant at FSM in Nis, in the period from July 1, 2013 to January 1, 2014, are given. It was found that in this time period the average values of the experimental and simulation calculated energy efficiencies of the PV solar power plant were 9.52% and 8.44%, respectively. The increase in the ambient temperature caused a decrease in the PV solar power plant energy efficiency; with an increase in ambient temperature by 1 ?C, the experimental energy efficiency decreased by 0.22%, and the simulation calculated energy efficiency decreased by 0.07%. The obtained data could be used for the planning and application of PV solar power plants in places with a similar climate.

The purpose of the Article, to make a survey on domestic energy regulation from the prospective of climate protection. The basis of the survey is the new National Energy Strategy published in January 2020, which defines those milestones being the significant climate protection topics of the next decade from economical, technical and regulation perspective. This mean three topics. The greater utilization of solar plants, in connection with I will examine the licensing procedure of small solar power plants, the grid connection process and the first experiences of the METÁR tender. The improvement of the energy efficiency, for that I will pair an inspiring austrian example. Finally, greening transport, within that I will make a fresh regulation analysis which intends to follow the lively development of electromobility.

Abstract Integration concept of energy resources can complement between the competing energy technologies. This manuscript presents a comprehensive review on the state-of-the-art of concentrated solar power (CSP) integration technology with various energy sources. Compared to CSP alone, integration of CSP and fossil fuel provides promising solution to solar energy intermittence, emissions and installation cost reduction, with 25% increase in electric power generation. On the other hand, integration of CSP with other sources such as geothermal and biomass can supply dispatchable power with almost zero emissions. The electricity produced via integrated CSP and photovoltaic (PV) has better power quality and less cost compared to that produced by PV alone or CSP alone, respectively. Integration of CSP and wind energy can meet peak demand, reduce power fluctuation and provide electrical power at a high capacity factor. However, the lack of reliable biomass, geothermal and wind data with the solar availability at specific locations is the main obstacle for the acceptance and further deployment of hybridization systems. The advantages and limitations of the hybrid technologies presented in this paper according to the literature are reviewed. Moreover, future directions of CSP such as production of hydrogen, solid particles receivers and the integration of supercritical carbon dioxide cycle are also discussed.
