The data seems to be mixing a small portion of the Golmud Solar Park land mass with its latest power generation (2.2 GW). This article [1] says:
"With a capacity of 2.2 GW ac (3.1 GWp), the new plant in Qinghai’s Gonghe County is the world’s largest single solar installation. Covering over 52 sq km, it was built by Huanghe Hydropower in just 10 months and connected in September 2020."
So they're basically the same "size", though both have a lot of gaps (see pictures at [2]). Seems like the solar folks draw a convex hull around the area to use as a guide. The map views at [3] and [4] will let you decide for yourself :).
