SOLAR DEVELOPMENT IN UZBEKISTAN. STEP 1: SOLAR DATA COMPILATION

Solar radiation resource data serve as fundamental information for programs of large-scale deployment of solar energy technologies. While solar resources in the Republic of Uzbekistan are estimated to be significant based on limited information, comprehensive understanding requires considerably more data and analysis in order to optimize the process of planning and siting solar energy power plants. This paper highlights the analysis of the four-year of solar resource measurements from new ground meteorological stations in Uzbekistan which were installed within the framework of the project of the Asian Development Bank TA 8008 "Development of solar energy in Uzbekistan" in 2013.The current study should have significant applications for preliminary technology selection, power plant modeling, and resource forecasting. The analysis uses4-year (January 2013–December 2016) data from 6 stations located in the south-eastern part of the republic based on ten-minute measurements of Global Horizontal Irradiance (GHI), Diffuse Horizontal Irradiance (DHI), Direct Normal Irradiance (DNI), and related meteorological parameters.
