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.
