It's the ones around the cells you will have to address. Are you planning on just replacing those and leaving the shingles under the cells? Even if it is touted as being a 30 year roof we all know how that works out.
On the main back roof of the house, no shingles will be (should be) exposed. The garage/bonus room, well, that's another story. The north facing roof will have no panels on it. If money were no object, I'd put them there, though. Just to honk off my HOA - cause they can't do anything about it and stuff.
