There are some interesting oven designs that use rooftop solar collectors (mirrored troughs with a tube of transfer fluid running through them) connected to normal-ish form factors ovens downstairs. It’s basically the same setup for solar steam generators (if you run a business that uses a lot of steam). The only problem is it’s a direct use of the heat without much storage (from what I remember) so you can’t really start baking before sunup.
There are also some cool designs for direct solar that point a reflector dish into a hole in a wall (the inside of the hole is the inside of an oven in the kitchen). Tamara solar kitchen has one but there are lots of similar versions.
This is an awesome outlook, thank you for all your work on this design!
