Abstract

This paper presents a comparative analysis of the thermal efficiency of flat plate and vacuum tube solar collectors under the climatic conditions of Uzbekistan. Using experimental data, the study evaluates the performance characteristics including thermal gain, efficiency curves, and daily output under identical operating conditions. The findings show that vacuum tube collectors demonstrate higher performance at lower ambient temperatures and are more suitable for high-temperature applications. The study provides scientific evidence for choosing the optimal type of collector for transformer oil purification and other thermal applications.

Keywords

solar collectors, flat plate collectors (FPCs), vacuum tube collectors (VTCs), analysis, efficiency and climatic conditions.
