Abstract
The use of natural environmentally friendly resources in engineering systems, in particular, solar energy technologies, helps to cut energy costs, thereby reducing production costs and anthropogenic load on the environment. Long-term hydrometeorological data were studied and processed using mathematical statistics methods, the reliability of the interaction was determined, and regression equations were obtained to predict the natural and climatic conditions along the coast of the Kara-Bogaz-Gol Gulf in the Caspian Sea. Natural solar energy resource potentials of the gulf coast were considered. Using innovative techniques, the task is to assess the thermal resource potentials of solar radiation; consider the salt deposits of the gulf as heat accumulators for the development, implementation and application of solar thermal energy technologies; and justify the technical and economic feasibility of their use in engineering systems in the gulf. For development, creation and implementation of solar thermal and electric power stations in the study area applying innovative methods with consideration of natural and climatic conditions and atmospheric phenomena, gross, technical, economic and environmental capabilities of the region were assessed. The solar energy potentials of photoconverter and heat collector at the optimum tilt angle were estimated based on theoretical studies and methodological calculations, taking into account duration of sunshine; hour angle to inclined and normally oriented surface; movement of solar declination to an inclined surface and to the horizon; scattering of radiation, albedo, angular parameters of arrival and solar radiation; average monthly and annual temperature of outdoor air and operation of a solar installation; specific energy parameters of a solar installation, etc. The obtained scientifically substantiated and systematized results can be used in the development of design and estimate documentation, preparation of feasibility studies for the creation of various solar technology complexes in the Caspian region, which will contribute to strengthening of energy security, sustainable development of energy systems when using autonomous technological units based on solar energy, growth of production of natural chemical elements, reduction of energy consumption of organic fuel, and improvement of the environmental situation in the region of the Kara-Bogaz-Gol Gulf.
