Who the hell ever told you that?

New technology is usually where we FIND large economies of scale.  Manufacturers
invest in new technologies that promise new efficiencies and lower unit costs,
which gives them a temporary advantage in the marketplace until their
competition catches up by either adopting, improving, or taking the next jump to
yet another new technology.  For a wonderful example, look at the memory market
over the last 40 years.


Boy do you have THAT right!  That seems to be especially true in the PV world.
Two or three times a year we hear of some new technology that is going to take
PV prices through the floor.  So far, the changes we have seen have been more
evolutionary than revolutionary.

There's certainly no guarantee that it will materialise, but
experience does suggest that there is reason to be hopeful.

And "inventing a different technology" is making an artificial
distinction between the small incremental improvements which we know
about and expect and the slightly larger improvements that look less
obvious in highsight. Improving technology always involves changing
sonething, and some of the changes are more obvious than others.


They certainly look cheaper to me than they did when I was a graduate
student. Battery technology certainly hasn't improved dramatically
over the last fifty years - the inventors who were busy in that area
around the nineteenth century do seem to have picked off all the low-
hanging fruit, but the inventors did lose interest once the internal
combustion engine put paid to the electric car (whose popularity
peaked in 1912).

Perhaps the current market is just too small?

NONE of the subsidies address the economies of scale of emerging solutions.

Instead, they REWARD ripper offers for business as usual, paying people

And SETTING BACK eventual net pv breakeven by many DECADES!

Actually quite "cost effective" for a school!

Many schools are "building rich" and "operating budget" poor. That is they
can easily find millions and millions of dollars to build new buildings -
and this money can only be spent on that.

Yet they can't find enough money to pay day to day expenses. They might have
trouble coming up with an extra $ for blackboard chalk. Seriously!

So quite smart of them to use that construction money for something like
solar which would reduce their day to day expenses. Perhaps they will be
able to buy chalk in the future?
