Principles of Cathodic Protection Using Solar Panels for Marine Structures Located Away from Stationary Electric Power Sources

Abstract

The operability of the device for cathodic protection of metals in natural seawater using the solar panel as the only direct current source was experimentally studied. It was shown that the cathode device, powered only by a solar battery, allows cathodic protection of marine structures with a degree of protection of up to 86% without the use of additional energy sources. Protection is achieved by the formation of calcareous coatings in the daytime, which provide protection in the nighttime, when the cathode current is absent
