[RE-wrenches] Sanyo Bi-facial

[Doug Wells]

Bill,

I am not going to go off about Sanyo modules, especially the bifacial  
brand.  However I will say this.
I have installed a lot of residential systems with their panels.  I  
installed a system at a retired engineers home last summer and he is  
keeping very close records of production.  We are commonly seeing  
production which is at or above nameplate rating ON THE AC SIDE.  A  
3.6 kW array is producing 3400 to 4,000 watts AC on cold sunny days.   
This is not the norm in PV production in my opinion.
This brings up 2 questions for me
	1.  Why the hell are very intelligent engineers overloading inverters  
with DC production.  I know the easy answer is Nameplate DC rating for  
incentive programs.
	2.  Is the multi-junction Amorphous approach all pumped up the first  
5 years and then going to let go in year 18?

Thoughts experience?  Can't deny the early production in VT.
