Summary:The grid-connected 130 kW photovoltaic power plant, built-in Namangan district with the support of the South Korean government and technology, began operation in 2015. The photovoltaic power plant consists of four type modules and three type inverters from different manufacturers. One of the primary purposes of this pilot PV system was to promote the photovoltaic industry by researching the impact of the electrical and climate environment to the energy production. In this work, the authors simulated the 130 kW photovoltaic plant with Solarius PV software and compared the results with reference values, which were submitted by Korea sides. The power output characteristics of the PV system by varying the tilt and azimuth values of the module arrays are also estimated. The authors recognized that simulation software could be useful for photovoltaic plant design and verification. On the base of analysis of electrical energy production yields of on-grid Namangan 130 kW power plant during one-year period was shown that power production in the winter season, such as the November, December, and January has dropped significantly by up to about 80%. The analysis of the study results showed that any deviation of the actual energy production values from the values of the simulation results by more than 10% can be caused by issues (outage, overvoltage, and undervoltage) due to increasing load in the electrical grid.
