What's messing with people's heads when it comes to predicting solar is the perfectly rational tendency to base projections on past and current data. I think it qualifies as a black swan event for this reason.
Batteries have become dirt cheap to make and we are very quickly getting to the point where the power electronics are actually the more expensive part of a battery deployment rather than the battery capacity itself.
The real defining fact about solar and battery storage is that it is very amenable to mass production and scaling. Small modular components that can be produced in a factory and require minimal maintenance.
I'm in no crusade to make people think like me. I am on a path of leveraging my knowledge.
