Electroysis and PV mounting hardware
Options
System
Posts: 2,511 admin
I'm doing a ground install, using galvanized pipe (similar to GroundTrac system), with galvanized steel channel struts. The panels will be bolted directly to the struts. Panels are anodized aluminum coated. Does anyone know if there are any electrolysis issues with bolting anodized aluminum panels to galvanized steel? It's a dry climate here, so moisture will be infrequent.
Thanks,
Greg

use stainless for the panel to rack hardware, the coating on the frames will protect the panels and last for decades -

Hey, Solar guppy:
Are you saying to use stainless steel bolts?
The plan, so far, is to bolt the galv. struts directly to the back of the panels, using the slots in the struts to go through to the tapped holes already on the panel frames. This would put the steel struts in direct contact with anodized aluminum coating on the panels. Are you saying the anodized coating on the panels prevents electroysis with the galv steel struts? -

The Strut to panel hardware should be stainless
Yes the coating protects the frames
