Cathodic corrosion protection with solar panel
11105001 · 2021-08-31 ·

A metal section in concrete or mortar material is protected against corrosion by providing an anode and a solar panel where the solar panel and the anode are supplied for installation as a common unit where the anode is mounted to the rear of the solar panel with an optional storage component therebetween. At least a part of the anode is attached to a surface of the material and one or both of the anode and the solar panel is flexible to conform to the surface. In installation, a light meter is used to determine levels of ambient light for example in an interior location not in receipt of direct sunlight and details of the material and metal section at the location to calculate a required location and size of the solar panels and the anodes.
