If you are bonding dirt, it has to be copper. If this is encased in concrete it can be the steel rebar or presumably after 2008, steel mesh.
I understand some people do not think a single #8 is sufficient but Florida decided in 2006-7 that this would work and adopted the 2008 rule early as an add

Is there an exception for solar PV operated pool pumps?
That is the one thing on the PV biz that looks particularly attractive to me.
