> The importance of noting that solar is the biggest source of new power is that is signifies the economics of power generation have changed
Not necessarily. Solar becoming the biggest source of new power doesn't mean that there aren't any new projects for gas plants etc., and if people are still building new non-solar plants then solar's economics aren't always better than non-solar sources, particularly since the economics of power generation are very much geographically dependent.
Solar becoming the biggest source of new power is an important milestone, but it's also a relatively meaningless statistic. More important would be measuring the rate of change of solar adoption in new power generation projects, if it's positive then either new solar projects are bigger than previous solar projects (for a constant rate of new projects year over year, meaning that solar is scaling well), or the number of solar projects is increasing (meaning that solar has become relevant in more and more areas), or both. Either way, if you're concerned about solar adoption, that's the real statistic to track.
