When I put "rolling shutters" into Google Images, I got lots of pictures of the same thing, so I guess that's what they're called. I don't have any need to refer to them very often so I wasn't sure what we called them.
I also Googled "electric shutters" and got many of the same pictures.
Without a photo, if I just saw "shutters", I would imagine the small wooden ones which are on the outside of many Mediterranean residential homes' windows and which you simply reach out and open and close by hand.
