Perspectives of using Israel's experience in solar hot water supply in Ukraine

Abstract

This article raises questions about the use of alternative energy sources, the relevance of which currently and in the near future does not cause any doubts. Particular attention is paid to the problem of the average use of alternative sources in the energy sector of Ukraine. At the same time, the emphasis is placed on such a direction of ensuring comfortable living conditions as satisfaction of the population with stable and inexpensive heat for heating and hot water supply systems with the use of modern solar energy systems.To achieve this goal, the article formulated a number of problems that could more fully represent the disturbed topic.Some aspects of the state of the world energy market and the need to develop renewable energy sources, including solar radiation, are set out in the material to highlight the problems raised.With a view to possible use in the Ukrainian energy sector of solar radiation, Israel's many years of experience in the successful use of hot water heliosystems for domestic needs was considered.The estimation of the climatic conditions of Ukraine, which represents the good possibilities of using solar thermal energy in providing the proper conditions for comfortable living, is given.The state approaches in Ukraine and Israel for realization of national programs of development of solar energy, aimed at increasing the share of heat received in this direction in the general energy system are considered.The international, European and national standards of both states regarding the requirements for solar collectors with comparative analysis of indicators for their testing are presented.The state of production, practical use of equipment for solar hot water supply systems is analyzed, the main manufacturers and suppliers of this equipment are presented in the markets of both countries. In the tabular form a comparative analysis of the main technical characteristics of flat solar collectors of the leading manufacturers of the European Union and the State of Israel, presented in the Ukrainian market is presented.The list of problems, which is a restraining factor in realization of tasks on development of solar power systems, is shown. After the article conclusions and recommendations on the above-mentioned problems are made.
