Just had a quick look at the video, and I'm sure that there is too much shading on the panel, (there is shadow below the railing) to get close to its rated output, seldom get full output anyway.

If you were looking at the same point of view that the sun is hitting the solar panel you couldn't see the entire panel, so the sunlight cant get to it either......Explanation might sound a bit simple.

To prove if the panel is working properly, it could be checked laying flat on the ground in full sunlight, that might not be possible in your location?  

Removing diodes and bypassing a row of cells will lower the overall voltage output of the panel......unless its a split panel as yours might be, then you could bypass that section, depends on which direction its split.

likely shading is still a problem in that orientation, and I don't think you will gain anymore useful power, have you got a data sheet for that panel? that would help with the panel configuration.
