I can’t tell how much of the growth is residential or industrial installations (IMHO residential installations is where PV belongs), as the report that would likely tell me this is $4K. Still, growth in that industry means there is more money to be spent developing PV technology to make it more efficient & affordable (through increases in durability and reductions in rare earth components).
Yes, I know it still suffers from the Dark Flaw, and that won’t be overcome until PV cells can produce more power than is needed, and battery technology advances enough to store that excess.
