It can be seen in Fig. 15 that the annual power generation of the plant increases with the increase in SM and TCES capacity. This is because an increase in SM means an increase in the size of the heliostat field and more solar energy will be used for power generation. Similarly, the increase in TCES capacity means that more energy will be used

5.1 Working Principle of a solar collector . In a solar collector, the solar energy passes through a glazed glass layer and is absorbed. The solar energy excites the molecules produces heat and gets trapped by the glass layer.
In addition, the power generation efficiency of PV modules decreases as their temperature increases. The solar energy not absorbed by the PV cells during the PV power generation process is converted into thermal energy, increasing the temperature of the PV modules, and thus reducing the efficiency of PV power generation .
