Bill and Matt,

Meggering is hard on insulation. It may, or may not, be hard or harder on PV
cells .... that is the question. Could you guys please elaborate on that?

P.S.  Bill, your recent class here in Vermont was great. Thanks.

Just to add punctuation to this thread, I always recommend that contractors
megger their arrays, because it has saved my butt several times.

I only meggered the actual arrays on projects where it was a requirement and
I only did that following specific procedures provided by the module
manufacturer. No procedure from the mfr = No array megger.
