What struck me was, in the second photo, at the lower right, is a built up area that is flat on top with equipment and vehicles parked there. This is well away from the footprint of the Gigafactory structure. I suspect it is a staging area for startinging construction of a renewable energy source area, likely wind turbines.
That second photo is the best I've seen so far to clearly show that the current structure occupies only a small fraction (about a fifth) of the total factory footprint are.
Nice to see a wide angle view showing the whole area instead of drone videos up close.
