Victron panels may be different but unfortunately most other panels do lose most of their output if put in series and there is some shading on one of them. I have done this testing myself (similar to what you did) and documented it. I think the most valuable thing about your video is that people should test their panels before setting things up so as to guide their set up and what is necessary for optimum efficacy
I was thinking about rigging my panels (4x 100w Renogy cheapies that don't like shade) so that I could switch them between series and parallel so as to be able to choose how to best deal with shadows, or cloudy days when the voltage is too low. Do you think this would be worthwhile?
If the panel and cells have integrated bypass diodes, it will not block the whole string. Cheap panels don't have integrated diods and will block the whole string...
I guess most people with a Victron MPPT will not have Victron panels. More useful to most of us would be the same test with non Victron panels. This would also show us why we should get Victron panels in the future. Assuming that they are better etc...
