来自于日光的电能是真正“绿色”和廉价的能源，但是需要基于光伏(PV)电池和存储设备(例如电池)的能量转换系统。

Electricity from sunlight is truly "green" and inexpensive but requires an energy conversion system with photovoltaic (PV) cells and a storage unit, such as a battery.

能量转换系统也称为二回路系统，其主要功能就是将SG的热能转化为机械能，然后转化为电能。

The main function of the power conversation system, also called secondary system, is to convert the thermal energy from the steam generators to mechanical energy, in turn, electrical energy.
