The best consumer panels today do about 20%. If the efficiency was
2-3 times better that would be 40-60%. I would not be holding my breath. 

Compare that with price developments from Solarbuzz. Future
does look bright indeed.

Right now the demand has again skyrocketed. Once again production is
completely overwhelmed -- just try buying an inverter right now,
or try finding people to install it (this is Germany, YMMV, about 3 GW
to be installed this year).

I haven't seen any such mixture in any other blog yet. It made

can't he tell which is which?
