The plexiglass is 95+% of the added weight, and it's probably about 20 pounds. It would be about 10 pounds if I wasn't stupid and got the right thickness (the thinnest Lowes sells is much more flexible than what I got)

Yes! I have one string producing 7.25V up there that I can't come up with a use for unless I add more somewhere else later. I was thinking probably the hood, or also a neat idea would be the top 6" of the windshield, where it's tinted dark blue or black anyway. Hood is the flattest, and most ideal, though.

They were $2.50 each. Each was rated at 1.8W

These are those ones from Ebay, and most looked like new. Some had chipped edges, and a couple had cracks. Even the cracked ones work fine.
I got them from ebay seller fred480V, it looks like he sells lots of solar cells from his feedback, and he's got some new ones for sale now that are way more powerful than these. His auctions state something like, "best in the world right now" or "best available on Ebay at this time"
