Mick, I'm working at a site where four PV identical to your description (below) are mounted on a Zomeworks tracker about 20' in the air. I can't be certain about the cell count, but they appear to be 40 poly cells (4x10 and counted from the ground in a heavy rain, so I could be off count by a row), and definitely have a round bayonet-style j-box. Unlike the PV you mention, these haven't yellowed, but there does appear to be some delaminating of the backing. The labels also look to be intact and read-able. When it stops raining, I'll try to get some front/back photos and send them directly to you.
Dan ------------------------- I failed to mention that the mystery modules have 36 cells in a 4 x 9 layout pattern. Thanks to all for helping. I promise to declare one or more "winners" and close out this thread soon, to keep the noise level low on the List.
