Preliminary Calculation of the Solar Water-Lifting Installation

Abstract

Agriculture is one of the most important elements of the economic complex of the Republic of Crimea, which is confirmed by the high development of territories, about 70 percent of the area. To eliminate the acute shortage of water, the article proposes an autonomous system powered by solar energy. This will make it possible to provide water for irrigation on agricultural land. (Research purpose) The research purpose is in searching for and justifying optimal technical solutions for eliminating the problem of water supply to agricultural enterprises of the Republic of Crimea. (Materials and methods) Authors have analyzed the agro-climatic features of the Crimean Peninsula. The article presents the data on the depth of the aquifer on the territory of Crimea, the annual energy potential of solar and wind energy. The article proposes a variant of water supply using artesian water extraction systems powered by solar energy. Authors have calculated the parameters of the solar water supply system. The article presents a diagram of its work. (Results and discussion) The main advantage of a solar installation for water extraction is the ability to use it autonomously in remote areas, without resorting to the construction of expensive engineering structures, which allows us to solve the problem of water supply locally. To ensure the irrigation rate of the apple tree on the territory of one hectare with sufficient solar insolation, a water-based photovoltaic installation is a suitable technical solution. The article presents the total capacity and area of the photovoltaic plant. (Conclusions) The area of the photovoltaic station does not exceed one percent of the total area of the irrigated field. This installation will make it possible to solve the problem of water supply in the region, increase productivity and the overall standard of living of the population. The installation occupies a small area and has a high performance.
