Re: rust (none / 1)
Right on both counts: it's cathodic protection through the use of a sacrificial anode.

One of the most common installations for my photovoltaic systems, back when I was a PV designer in the 1990s, was cathodic protection of oil pipelines.  (others included powering hazard warning lights on oil rigs, and microwave telecom relays for PDO Oman). Renewables helping out the fossil fuel industry.  Strange world, huh?
