    "In July, it started constructing its largest solar power plant in the Gobi desert across 6,301 acres, capable of supplying power to 1 million households."

    6,301 acres translates to 25 sq km and on checking it out does not use PV panels or batteries.

    It's a heat system and uses molten salt to store the heat giving 15 hours of power (on a fine day of course).


    From Wikipedia

    Experimental salts using Lithium may have a melting point of 116°C while still having a heat capacity of 1.54 J/(g K).
