Those solar production numbers are exceedingly exaggerated. You need to add capacity factor to the solar install. Multiply your solar production by 0.2 to 0.3 or so and you’ll be in a better ballpark range.

Peak power usage for large scale facilities is not much different than off peak. Most megawatt plus builds I’ve been part of have less than 10% difference between peak and valley in terms of watts used. Perhaps the hyperscalers see a much larger difference but I have my doubts.
