AZ/NM have highly concentrated populations, so I would expect to see only a couple of hexagons over Phoenix and Albuquerque. Texas looking like that is pretty bad, but I suspect this has more to do with the data set.

I would expect Texans to independently go for solar, given the... complications of their power market.

I can access it fine (I am in the US). At this moment, 37.2% of the generation is from solar.

At the moment being important. Previous day it was higher at 38.8% but only for that 15min. As a percent of the whole day it’s much much lower. (California goes to 110% in the middle of the by comparison). It’s a good upward trend, I’m confident Texas will get there eventually.
