OK, it's panel. Not sure if the Canadian spelling is pannel.

Here's a graph of my 3x serial panels with 9 bypass diodes and each diode string is about 10V. Note how the panel voltage increases by 10V as the leafy shade moves off of the panels. For me if there is significant cost for a bypass diode for every cell then I would not be interested. Also mine and the common panel arrangement has the diodes in the junction box so easy to access if necessary and limited cost. Individual cells not so much.
With shading on one string my output is 8/9, 2 strings it's 7/9, etc. While there is an additional voltage drop of about 0.3V for the conducting diode that's rather limited.

The output is between 46 and 47 volts depending on the panel. That's a nice sweet spot for safe operation voltage.

I can't find that about those panels either.
And the full specs are listed for only one type of panel.
