Could I cut down scrap car windows?

Nope they are toughened and will shatter into lots of little bits.

Guess you could use glass but someone has already mentioned how one
would clean between them when the algae builds up. Wonder if copper
nails and a copper wire along the ridge would keep the algae at bay?

If they are near enough the right size they won't need cutting, just
cut the other slate to fit.

IIRC flat side panels are sometimes laminated or were. They can be cut
witha scratch and meths in the scratch set aflame.

Whatever it would be silly not to try. Failing that glass cutters
might sell seconds and sheep ends. A thin layer of clear silicon
smeared between two sheets would give you a reinforced ply.

If you use a galss pane you must ensure no dopey druggy will stand on
it, he might get hurt and sue you.
