“…The power supply system is decentralized, but the power supply scheme associated with the centralized system is complex. A block diagram of the use of traditional and non-traditional energy in the power supply system is shown in Figure 3 [9]. In a centralized and decentralized energy supply scheme, electricity can be obtained from traditional or non-traditional energy [10].…”

This article discusses the development of a system for the combined use of solar and water energy based on a systematic approach to power supply. An improved physical model has been developed based on a model for predicting the production of electricity, taking into account the power and time of solar radiation, the amount and speed of water flow. At the same time, the share of electricity in the use of solar and water energy was determined simultaneously, depending on the conditions for the uninterrupted supply of consumers with the daily necessary electricity. The assessment of indicators of the combined use of solar and water energy and the definition of energy efficiency were developed by the authors on the basis of an increase in the share of electricity obtained from renewable energy sources in the electricity supply, which is explained by the coincidence of theoretical and experimental results.

“…The solar energy gross potential totals 2 134 x 103 PJ, while technical potential is estimated at 7 411 PJ, which is equivalent to almost four times the country's current primary energy consumption [2]. There has been overwhelming researches and studies regarding utilization of solar energy for different purposes, mainly for heat energy and electricity production [3][4][5][6][7][8][9]. In the scientific work [10] two types of photovoltaic, monocrystal and polycrystal, modules were tested under Tashkent region environmental condition to determine the influence external condition on photovoltaic energetic performance.…”

The energetic performance of autonomous solar powered refrigerator is analyzed. In this refrigerator, the solar energy is converted into electrical energy by a photovoltaic (PV) array, then the generated electrical energy is used to power a vapor – compression system which produces cooling energy at its evaporator. The evaporator is sunk to the water so that produced cooling energy is used to formation water ice, thus accumulates cooling energy in the form of ice. While, compressor is working during the daylight hours, cooling energy is produced. During the night, the cooling energy comes from latent heat of fusion of ice which is collected in day time. The results of experiments showed that not only the solar energy has influence on the energetic performance of solar refrigerator but ambient temperature is also crucial factor in this case.

“…Nevertheless, in Brazil, the solar system is used to heat water in winter despite high initial costs that are balanced by the low cost of energy when using the solar system [21]. Solar energy is also used in agriculture in Vietnam [22], Uzbekistan [23] and Ukraine [24] and in self-powered Small Base Stations that are the constituents of nextgeneration cellular networks [25]. Solar systems are also used in combined systems for the production of both thermal and electrical energy [26].…”

“…An autonomous solar power plant was used in agriculture in Uzbekistan, but the use of solar panels may not be so profitable considering the high cost of installation and necessary repairs. In the study, only two solar panels were used with a total cost of about EUR 483, including installation and the price of only about EUR 65 per one piece of solar panel [23]. Considering 32 panels, the price would be about EUR 7700, which is much lower than the solar system in Slovakia.…”

The study deals with the analysis of data from a selected tourism facility and the implementation of a solar system and a rainwater system, which are an alternative to commonly used energy sources. The objective is to evaluate the potential savings from the use of the solar system for water heating and the rainwater system for purposes other than potable use with respect to local conditions of sunlight and rainwater variability. The facility holds 257 beds allocated in 124 rooms on 5 floors. The result of the contribution is an economic evaluation of the efficiency of investments in the proposed systems and the resulting recommendations in the field of energy flows in the selected facility. Appropriate formulas including the consumption of hot water, the amount of energy needed to heat water, the cost of the consumed energy necessary for heating and the average annual rainfall in the location, water consumption for clearly identified purposes of alternation with rainwater, the initial investment costs and operating costs of the solar and rainwater systems, were used for an economic evaluation of the investment into the solar and rainwater systems. Based on the economic evaluation, the economic efficiency of the proposed systems and the return on investment was calculated. The payback periods for the solar system used for hot water heating and the rainwater system used for non-potable purposes, accepting the local conditions, are 7 and 15 years, respectively.
