The integration of renewable energy with storage technologies has become a key research focus, as it enhances resource utilization and balances grid supply and demand. This study investigates a solar-assisted thermal support system designed to provide medium-temperature heat for Compressed Air Energy Storage (CAES). The system incorporates a multi-curved parabolic trough collector whose performance was evaluated under real-weather conditions to assess its capability for stable heat delivery. Experimental measure ments were used to characterize the thermal behavior of the collector, and a coupled MATLAB/Simulink model was developed to examine how the collected solar heat affects CAES discharge performance. The results show that the solar heating subsystem can reliably provide the temperature levels required for CAES operation and contribute to an improvement in expander power output. The combined experimental and modeling analysis offers practical performance evidence for integrating solar thermal input with CAES, complementing existing studies that have primarily relied on theoretical or simulation-based assessments.
