Abstract
This article investigates the main technical challenges arising during the operation of solar photovoltaic power plants in the Karshi region based on a scientific and technical analysis. The climatic and energy conditions of the region, including annual global solar irradiation (1500–1700 kWh/m²), high summer temperatures (up to +45°C), and dust accumulation (soiling) effects, have been evaluated in terms of their impact on photovoltaic system performance.
It is estimated that although a 5 kW photovoltaic system can generate approximately 8,500 kWh/year under ideal conditions, energy losses due to high temperatures and soiling may reach 20–25%. Based on the temperature coefficient (β ≈ −0.45%/°C), it was calculated that the power output may decrease by 15–20% during summer months. Furthermore, it was determined that soiling causes an average annual energy loss of 10–12%.
Based on the research findings, technical recommendations have been developed to reduce operational losses and improve system efficiency.
