It's a significantly bad thing if something as straightforward as buying and plugging in solar panels requires special knowledge to not get screwed over.

Oh come on.
And it's even plausible that ERCOT currently can't handle additional PV in whatever area the Roby parcel was in without adding BESS, although the person you're responding to has no idea if that's true or not, since neither they nor I knows where that is.
The conclusion in the post:

Okay, how small of a connection would they have to restrict him to for me to be correct?
> BESS, simple curtailment at peak hours, or angle diversity would solve the problem.
That much extra curtailment is a major problem. That much extra angle diversity hurts output. Batteries are a workaround for not being able to properly hook up the panels.
Onsite BESS permits you to not only get by with a smaller hookup but also sell your energy at times when people are willing to pay for it.
I did my calculation already. It said that a 1/3 drop in hookup for panels that were already hookup-constrained is not a proper hookup.
Straightforward math.
He was doing it for the tax credits. Without the tax credits, this project wouldn't have come close to making sense.
That doesn't make pure solar installs bad. Pure solar installs are net positive.
