Solar energy resources of Ukraine for 1990 - 2020
Abstract
The purpose of this article is to assess the potential of solar energy resources of Ukraine to determine the prospects for the use of natural energy sources for 1991 - 2020.
Main material. In the conditions of modern climate change, the energy independence of our country with the use of alternative renewable energy sources, which determine the economic feasibility of their use in energy-dependent sectors of the economy and various spheres of human activity, is gaining importance.
For this, a database of individual components of the radiation regime was formed using the archive of observations of the meteorological and actinometric network of the Borys Sreznevsky Central Geophysical Observatory of the SESU. When obtaining their spatio-temporal distribution, the methods of mathematical statistics and cartography were used.
Specialized indicators of climatic resources of solar energy for individual actinometric and meteorological stations of the country are presented. According to the changes in the components of the radiation regime, the values of these indicators are given for: 1991 - 2000, 2001 - 2010, 2011 - 2020. The contribution of direct solar radiation to the total for April - September, the contribution of total radiation for April - September to the annual sum was determined. Based on the monitoring of short-wave radiation flows, the increase in the duration of sunshine and total solar radiation during the study period is presented. Their spatio-temporal distribution is given and the possibilities of introducing solar energy resources are established under the conditions of growth of the annual sum of the duration of sunshine above 2000 h and the annual sum of total solar radiation above 4000 MJ / m².
Conclusions. The article has obtained gradual increase in the potential of solar energy resources in Ukraine was obtained.
