[RE-wrenches] The Demise of Reason, SunPower and WEEBs

[Peter Parrish]

I think we have made some progress here on the story line. So let’s see if
we can understand what happened "due to UL testing changes".

One other random question. I believe that SunPower permits drilling their
frame for the purpose of accommodating the lay-in lug, for example the
outside of the shorter dimension. Can anyone confirm this?

Peter,

The document that you have was correct at the time.  Then, in December of
2008, SunPower issued a tech bulletin which stated that SunPower modules
were no longer listed for use with "grounding clips".   This bulletin states
that lay-in lugs are the only grounding option available that will comply
with their warranty.  We continue to nag SunPower about getting their
modules relisted for use with a WEEB or equivalent, but it has not yet come
to pass.

SM does refer to UniRac SolarMount.

Thanks,

Mark
