Because after the solar energy is introduced into the coal-fired power generation system as an external energy source, the total energy inputted into the TSACPG system will be increased greatly. So, the reduction of the overall system thermal efficiency is due to the introduction of the solar energy and its relative lower efficiency in comparison …
