Tom,

Turns out that they are not as I thought.  Of couse I am refering to 
SA1 (solar array number 1).  SA2 and SA3 were different, more 
conventional.  SA1 apparently had small cells "attached" to a 
flexible substrate that was rolled up.  So, the cells were not 
flexible, and the subarrays were not stiched together.

From: http://www.esa.int/export/esaCP/ESAKKXU9EYC_Life_0.html

"Designers came up with a solution where the solar cells are attached 
to a flexible
blanket that can be deployed and retracted - essentially rolled out 
and in around a
central drum, like a roller-blind. "
