Comparison对比

Hybrid capacity structure混合式装机结构

Most of the project’s capacity comes from photovoltaics, while the smaller CSP component adds thermal storage and evening-generation capability. This combines high daytime generation capacity with a solar-based source that can operate after sunset.项目大部分装机来自光伏，而规模较小的光热部分提供储热和晚间发电能力。这种组合将较强的白天发电能力与可在日落后运行的太阳能电源结合起来。

Storage links daytime and evening supply储能连接白天与晚间供电

Electric heaters transfer surplus daytime photovoltaic output into the CSP plant’s molten-salt storage. After sunset, stored heat and heat from the receiver drive a steam turbine to serve the evening demand peak.电加热器将白天富余的光伏电力转化为光热电站熔盐储能中的热量。日落后，储存的热量与吸热器产生的热量共同驱动蒸汽轮机，以满足晚间用电高峰。
