grounding plate vs. rod? [RE-wrenches]

[Scott Russell]

Hello, all. 

I'm installing PV in Nepal for a Kathmandu-based company. They typically use
copper grounding plates (18"x18") here rather than the grounding rods I'm
familiar with back in the good ol' USA. Our Nepali techs claim that the
local soil composition necessitates taking extra steps to increase its
conductivity. That is, using the larger surface area of a plate as opposed
to a rod and burying it parallel to the surface, two or more meters deep
sandwiched between two layers each of salt and coal. Does this sound
reasonable/plausible? As you might imagine, driving a grounding rod is much
more appealing to me than (hand) digging a 24-inch diameter hole, 7+ feet
deep.

Thanks in advance for you insights.
