Sunpower Panels

 Anyone out there have experience with Sunpower's 210 White panel? Or
any of Sunpower's modules? Good? Bad? Ugly? Thanks.

Seriously, though, I haven't heard anything bad about them. The one
thing you should be mindful of is that they're made slightly differently
from most PV modules, and for best results your system should have a
positive ground if you use them (your installer should know what that
means if you don't, or at the very least should ask Sunpower about it).
For various reasons this makes them unsuitable for off-grid use, IMO,
but they should be just fine for grid-connected applications.

 
I looked at the data sheet and I dont see the rational for your statement.
Is it a mechanical construction reason? Please elaborate...

Cheers

 
I heard something about a unique back-contact construction of their
cells, which needs a genuine earth ground to get rid of charge-
buildup.  I could be wrong, though.

 
Ok, I see. They recomend it
