Question: Are stranded wires allowed in this installation? Or must the grounds be solid copper?

From the 2002 NEC.

250.62 Grounding Electrode Conductor Material.
The grounding electrode conductor shall be of copper, aluminum, or copper-clad aluminum. The material selected shall be resistant to any corrosive condition existing at the installation or shall be suitably protected against corrosion. The conductor shall be solid or stranded, insulated, covered, or bare.

But it should be attached to the wall or protected with conduit.

Thanks for the NEC ref Jerry, that's what I was looking for! ;-)
