It depends on the type of panels. If they are fiberglass, then they will absorb sound on both sides. If you have the ceiling room (cathedral ceiing), these can make a very effective treatment option. I recently designed a very large home theater with 15 4x8 foot acoustical clouds and baffles
hanging from the ceiling!
Hanging, angled reflective panels redirect sound, and improve diffusion. You find them in laboratory reverberation rooms, which need to be extremely "live" but also to have very diffuse sound fields.
