Interesting training videos on the 3M website covering recommended practices
in taping splices.

Can anyone give me the NEC reference for taping UL-listed wire splice
connectors (indoors)? Does the tape need to be UL listed? Anything else that
pertains?

Friends:

I was incorrect on one point in my previous post on the subject.  The
SolarWorld SW230 is comprised of one series string of cells.  It acts
somewhat like there are three strings because of the bypass diodes. If you
shade one cell of one group, the bypass diodes kick in and allow the module
to continue to produce power but at a reduced level.

Our test showed that if the short edge is shaded for more than half of a
cell width on the narrow edge, the total output caved.  The same shading on
the long edge reduced output minimally.
