Do you like spherical shapes or true paraboloids for solar use.

your big dish has a rather slight curve but it’s still surpruising how close it’s focal length is.

it seems that if you want to focus onto something a few meters away, one only needs an ever-so-slight curve. Perhaps just a normal flat panel of something – with a slight vacuum behind it will provide enough curvature.

I wonder if a large flat GLASS mirror will be able to be tensioned like hat and not break. Perhaps it is possible.
