摘要

This study experimentally investigates the thermal and electrical performance, economic feasibility, and environmental impacts of a hybrid energy system integrated with a parabolic trough collector (PTC) and thermoelectric generator (TEG). In the established system, solar energy is converted into electrical and thermal energy using a steam turbine and TEG. Experimental data indicate that the system operates with an average efficiency of 71.44%, which varies depending on the intensity of solar radiation. The overall energy efficiency of the system is calculated as 14.51%. In the economic analysis, the payback period of the designed system is approximately 5.4 years, while the levelised cost of energy production (LCOE) is calculated to be 0.075 USD kWh−1. The environmental assessment indicates that the system can prevent 356.18 kg of CO2 emissions annually and save approximately 1499.72 L of water. These findings demonstrate that hybrid systems offer an economically and environmentally sustainable and efficient alternative to energy production.
