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.
