Under the conditions of high solar activity in the Khatlon region, improving the efficiency of photovoltaic systems becomes particularly relevant. The aim of this study is to evaluate the impact of solar irradiance variability and temperature on the output power of solar panels. The experiment was conducted at a 10 kW autonomous solar power plant using a lux meter and an infrared thermometer to measure insolation and temperature. A correlation analysis was performed, confirming a direct relationship between the level of insolation and output power, as well as identifying the negative influence of temperature on efficiency. The results demonstrate pronounced daily and seasonal fluctuations of solar radiation, which significantly affect electricity generation. The practical significance of this work lies in the development of recommendations on the placement, orientation, and operation of solar installations to improve their performance under the conditions of Tajikistan.
