This study presents an exergy assessment of an operating 1 MW photovoltaic power plant located in the Qibray district of Tashkent Region. A distinctive feature of the facility is the installation of bifacial N-Type TOPCon modules with a rated power of 640 W and an efficiency of 23.7% along the perimeter of an apple orchard on non-irrigated land. The parameters of the solar energy flow at an irradiance of 850 W/m², the exergy of solar radiation (~3.35 MW), and the calculated exergy efficiency of the system (~29.9%) were determined. The main sources of losses include module heating, reflection of solar radiation, losses in inverters and cables, as well as operational factors, including surface contamination of the panels. The results show that exergy analysis complements conventional energy auditing and contributes to identifying opportunities for improving system efficiency. The environmental and economic benefits of the project are associated with preserving irrigated land for agricultural use and reducing CO₂ emissions.Keywords
