solar panels on space station [RE-wrenches]

[Travis Creswell, Ozark Solar]

I originally heard 65 kW of power but then this morning on NPR I heard the
42 kW.  That got me to thinking...

240'x38'= 9120 ft2 or 847m2

Using 1000w/m2 (ideal conditions on earth) there is 847 kW hitting that
array

847kW (potential) vs. 42kW (actual) = 5% efficient

How can that be?  Wouldn't it be higher than 1000w/m2 in space?  Don't they
use much better cells (GA AS)  Sounds like they need a good RE-wrench up
there?  Is the frame taking up that much?  at $32,000 oz to get something in
space you think they would use as little frame as possible?
