Anyone ever see little dots on the solar cells themselves? These are uniform on each cell on this panel. I'm getting decent wattage during testing so I dont think they are affecting the output, mainly curious.

100 watt rated panel, peak output 82 watts at 50 F. Clear skies, panel at a nearly vertical tilt 70 or 80 degrees, winter Sun.

White dot in the cell. Same dots in the same place on every cell on the panel.

I’m sorry, but your pictures are quite out of focus… it is hard to tell what you are asking.

Can you get a picture in focus, and instead of circling the entire cell, draw an arrow pointing at the spot you mean.
 
Sorry about the out of focus pictures. I can't seem to get better pictures.

I'll not worry about the holes in the cells then. Hopefully I can get some decent sun before it snows and get some more output measurements.
