[ExI] Inkjet printing could change the face of solar energy industry

I hate to disagree with you twice in one day Jeff...
But NanoSolar has been in production with a continuous printing
process for a couple of years now. The high cost of solar
photovoltaics really isn't so much about the panels themselves, but
all the equipment to store and distribute the electricity thus
generated. The cost of batteries, inverters, and so forth swamps the
cost of the panels themselves in small scale applications (like MY
house). Nanosolar proposes to solve this problem by creating
neighborhood sized installations covering a few acres and serving a
few hundred homes. This gets the required economies of scale for the
parts of the system that are not the panels themselves.
I would get really excited if someone figured out how to make
inverters cheaper, or batteries. Working on the panels themselves is a
Here's the thing. If solar panels were absolutely 100% FREE, it
wouldn't come close to solving the problem. More than half of the
current costs are in the batteries and inverters.
