Inside a building we found two of these panels, that hopefully show up in the pictures.
Can anyone tell me what they are used for?
They appear to be about 4x10 and 4 inches thick.
Thank you in advance.
I strongly suspect those are solar hot air panels, i.e. solar thermal panels. A picture of the back and sides would likely reveal two ducts for an inlet and and outlet for the air.

On my planet I'm considered quite beautiful. Thanks to the poetry in this tiny ad:
