That’s part of it, but America is also a country that routinely achieves economies of scale and loves to build stuff so there is clearly more going on here. Look back at what was commercially and technically available 15 years ago and it is not a viable mainstream energy supply at the scale needed to have the deployment we see today. The US developed a number of key innovations that made this feasible. A lot of this was funded under Obama era energy policy, but no efforts were made to protect the native industry from an unsustainable market force which sadly meant that the policy did not get the ROI that it might have otherwise achieved.
