This article provides a comprehensive analysis of using parabolic trough collectors (PTCs) for industrial heating in Tashkent’s climate. It examines the energy, environmental, and economic benefits of this technology, considering various temperature modes and system configurations. Using the System Advisor Model (SAM) software, the study identifies optimal parameters for the solar multiple (SM) and thermal energy storage (TES) system to minimize the levelized cost of heat (LCOH). Optimal configurations achieve a 46% capacity factor (CF) with a SM of 2 and 12-hour storage, resulting in an LCOH of 3.6 ¢/kWhth for medium-temperature systems, and a CF at an LCOH of 4.2 ¢/kWhth for high-temperature systems with a SM of 2.5. The environmental analysis shows significant potential for reducing greenhouse gas emissions compared to conventional heating sources. The findings validate the economic viability and environmental efficiency of PTCs in Uzbekistan and can inform strategies for integrating solar technologies into the region’s industrial sector, supporting decarbonization and sustainable development goals.

Key words: Parabolic trough collector, System Advisor Model, solar multiple, levelized cost of heat, thermal energy storage.
