I know most of us disclaim them, by FYI here's a good article on inspecting PV installations:

"...some systems will be installed with a dc grounding electrode conductor connected to a dc grounding electrode or to the ac grounding electrode."

What's the difference? And what's the difference between an ac GEC and a dc GEC?

[Greg Fretwell]

Since the code requires all ground electrodes on a premisis to be bonded together in one grounding system it is somewhat moot.
