[RE-wrenches] Sunpower micros and mysterious outages

[Hilton Dier III]

Friends of mine got a Sunpower system installed last year. Ever since 
then they have had intermittent problems with circuits in their house 
going dead.

The array is 14 each Sunpower SPR E20 327 C AC. The array is mounted on 
a corrugated steel roof on their garage, about 20 feet from the house.

What happens is that a circuit in their house will either go dead or 
brown out so lights barely glow. This happens to various circuits and at 
any time of day or night. The rest of the circuits will work fine and 
the event will last an hour or two. The breakers don't trip. They have 
had two different electricians there to check the house wiring and it's 
all solid.

Any ideas? Some kind of metal roof capacitance?

Many thanks,

Hilton
