triple junction vs single crystalline [RE-wrenches]

[Matt Tritt]

Keith and Bob O,

20 year warranty.
The solar crew (three people works best) does the laminating to the 
roofing panels prior to the roofer installing them. After the roof is in 
place, the modules are inter-connected by the guys who did the 
laminating. Quick, easy. no roofing skills required (except not falling 
off, of course). I've done it this way several times and it's always 
been done in extremely short time with no problems. On the other hand, I 
strongly suggest that the laminating be done in the shade before the 
roofers get involved. We always re-stack the finished "modules" the day 
before the roofing goes up so we can be out of the way.
