Assessment of the Technical Potential of Photovoltaic Convertors: The Case of the Fergana Valley Part I: Dynamics of Climate Data Changes in the Region
Аннотация
Changeability of the energy input from renewable sources, as well as climate change, accelerating by the day, dictate the need to study the latest climate changes in the country in order to examine the possibilities of using electricity generating installations and systems based on renewable energy sources, as well as for agro–climatic purposes in this territory. The first part of the research presents the results of studying the dynamics of changes in weather and climatic conditions in the territory of the Republic of Uzbekistan, the Fergana Valley in particular, during the period of 2005–2021 by means of collecting and processing climatic data obtained from nine weather stations located in the valley and suitable for scientific research purposes. It was revealed that during the period of 2005–2021, the maximum change in the average annual temperature in the areas of Fergana oblast was 1.58°C and the number of days with an average ambient temperature above +25°C varied between 100 and 121 days; direct beam solar radiation increased significantly; there was also a sharp drop in wind speed and the number of days with dust storm and drifting dust; and the amount of precipitation in the region in recent years was significantly less than in 2005. Due to the fact that the level of warming in the valley affects the generation capacity of crystalline silicon photovoltaic modules (PVMs), in order to predict their production capacities with the least error, it is necessary to prepare the most accurate source data on climatic and actinometrical parameters for their performance evaluation and survey works in the applicable part of the region.
