[RE-wrenches] third time charm

[Sindelar Solar]

Hmm... As I read this I think of the 23 year old array of 18 BP90 
modules that powers my own home. Back then modules were typically 36 
125mm cells, and the standard dimension for these was 21" by 47". So I 
don't think of a 16-module or 18 module array as large. Mine is on an 
early Wattsun tracker (I leave the tracking turned off so that it'll 
still be working when the time comes to sell my home) on a 6" sch. 40 pole.
