    The current commodity solar panel uses 20 year old technology. That technology has been optimized and I don't think will get cheaper. I do think solar can be less expensive, but with the adoption of new technology.

      but the bottom line seems to be that new technology is in the works, looks promising, will be more efficient at producing electricity, lowering costs so that in the future solar will be able to provide much more electricity at competitive costs, so the trendline will probably continue as predicted.

      It makes not sense to assume no technological advances.  I remember the stories about the suggestion to close the patent office as surely everything had already been discovered more than 100 years ago.  Human history doesn't support a prediction that new technology won't appear.   Will it be enough, soon enough, to stop us from destroying the climate to the point where life is vitually unsupportable as we know it,  that seems to be the question, not will solar continue to expand and be cheaper.

    •  IC chips use 50 year old silicon (0+ / 0-)

      we've been optimizing silicon for 50 years.

      I suspect there is a lot more room to optimize silicon PV.

      Remember a lot of very bright people lost their asses
      betting against silicon.

      GaAs which was going to be everything, well, Silicon
      ran it down.

      SIlicon ran down CIGS, which should have been 6X cheaper.

      Who knows, i think there is still a lot of room to go.

      What did Feynman say? Lots of room at the bottom?
