I have installed tons of SunPower 90's without any ground connection
on RV's with noticeable loss of power. I believe the problem only
occurs when you have a path to ground from the frame.

Hi Jay,
An interesting quandary indeed.
This is another good example of an application that I was trying to
grill Sunpower about --- as far as grounding their modules that need
to be positive grounded
in order to take advantage of their higher efficiencies. They
couldn't answer this simple question. How would you use one in an
airplanefor instance ?
There are solar powered airplanes (sort of) Is a large faraday
shield enough ? Sort of like the ground radials that Larry has
mentioned. I would
imagine that if you get large enough radials that it ~might~
approach being a virtual ground. Works for antennas though.
I like questions like this one. Sure makes one think a bit.
