To russell2030 (1 week ag) why do you ever need empty aluminum cans in there?

I think it ists in acting as another separation, but if you use recycled double glazing, matt black paper should work really well as it has a flash point well above any temp you will ever get in the cabinet, or a matt-blacked slim radiator or fire-bricks which will slow-release late into the night. Full sealed out-of-date cans of liquid will store heat the best for slow release after the sun goes down though:o)

What an excellent …
What an excellent idea. So if you have enough cans and link them all to flow one tower to the next with the cold air coming in at the bottom & zig zaging up to the top (horizontally not vertically), then you’d probably not even need the solar panel to drive the air! Hot air rises naturally, coz of convection. I knew someone who had a home made solar water heater that used covevection (no pump) simply because the panel was on the garden & the tank was in the attic. Hot water rises too!
