ANALYSIS OF THE GEOGRAPHICAL RESOURCE OF SOLAR ENERGY IN THE TERRITORY OF THE AGRICULTURAL OBJECT

Abstract

One of the tasks of a multifactorial assessment of the solar energy resource in the territory under consideration is to assess the impact of limiting the utilized resource by the building conditions of the location of the environment. When searching for suitable enclosing structures for installing photovoltaic modules, the geometry and spatial orientation of buildings, their relative placement, and shading effects are taken into account. The purpose of the study is to develop a criterion for identifying prohibited and permitted areas of the territory of an agricultural complex for the installation of photovoltaic modules. By eliminating areas with uneven lighting conditions, the photovoltaic installation can operate at maximum efficiency. Prohibited areas for the installation of photovoltaic system modules can be considered those that are shaded during a typical summer day, as well as during the peak intensity of solar radiation on all characteristic days of the year. Permitted areas for the installation of photovoltaic system modules can be considered those that are illuminated during every day of the year. The remaining areas must either be excluded from the installation plan for photovoltaic system modules, or various methods must be used to reduce the impact of module shading on their efficiency (installation of bypass diodes, the use of various module connection schemes, etc.). Using the example of the territory of an existing agricultural processing enterprise, the possibility of installing modules on the roofs of industrial buildings was analyzed, taking into account changes in the illumination of the receiving surface of the building roof slopes for peak intensity during characteristic days of the year. With an area of the enterprise territory of 55,748 m², of which 13.8% - 7,737 m² - is allocated for development, 2,377.5 m², or 30.7% of the roofs of buildings, can be used for the installation of photovoltaic modules, taking into account the insolation conditions of the territory.
