How to remove frame rubbing residue on the glass from mis-handled stacking of panels?

How to remove frame rubbing residue on the glass from mis-handled stacking of panels?

Per the title. I've got a pretty significant marring on the glass of a particular panel - it's not a scratch, precisely - but it's rubbed off (aluminum?) from another panel being dragged across it during re-stacking in the warehouse.

I'm wondering 2 things:

(A) how best to remove that rubbing (I've found instructions to not use sodium hydroxide (lye) that could normally dissolve the aluminum (assuming it is aluminum)).

(B) what kind of math /power am I loosing on this if it gets installed? The rubbing is over a single cell, and i have no idea what kind of "shade" the mar will cause.

What do you guys know?

EDIT: also - any you guys ever put a meter on a panel that has that rubbing on it to see what we're really loosing?

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well.
