    cookiebear, A Siegel the Solar Energy Research Institute (now NREL) in 1978-81, we've been hearing about economic solar is just around the corner, how this or that new invention or technique will mean solar power will be the only kind we need in three years or five years or, at most, ten years. Somehow, those inventions never quite live up to their hype.

    Solar is already economic in a few places far from the grid that need only enough juice to run some bulbs and televisions and a water pump or two. And, of course, the cost per installed watt has come down. But, in general, it's still well above the cost of other sources, including other renewables. And, I expect, that will be true for another 10 to 20 years, perhaps longer.

      Solar is economical already on the grid where peak power prices are high enough.

      As well, there are grid connection situations where it is economical with zero subsidy.

      Know of a chain of stores that chose to put in solar/battery as their backup power since it had the lowest maintenance of any package.  They would lose $10k in sales per hour of closed cash registers (on average).  Since putting in solar: zero hours of closed cash registers due to problems with grid power.

      But, yes, could wallpaper many homes with the promise of cheap solar around the corner (along with fusion ... nuclear power too cheap to meter ... etc ...). It might be just around the corner (and there are interesting developments), but ...

      •  if the goverments and power companies (0+ / 0-)

        will stay out of the way, it may just be true  this time..
          with  this form being so light weight and working on cloudy days, I would think it would be easier to  make it available for everyone.
            it's bound to be true at some point.
        after studying the  down side of  huge industrial wind turbines,, I'll  stay positive about this  solar.
