I have a question about stray current corrosion in reinforced concrete. I am working on a project in a parking garage with PV-panels on top of the roof. The ground is directly connected to reinforcement of the concrete, and because I know for certain that there is a small DC leakage current, that means there is a small current flowing through the reinforcement. Does this mean that the reinforcement will corrode?

I've read some articles about stray currents causing corrosion on metals when in an electrolyte, but i can't figure out what exactly triggers the corrosion process and that is why I am wondering if the reinforcement will corrode (and if so, why).
