[Max Balchowsky]

The early Siemens solar kits came with a heavy Gage plastic box that mounted on an "S" bracket tucked neatly under the panel.......It worked  well....

 You can get metal NEMA 4 and NEMA 12, gasket sealed boxes made by Hoffman.  There should be no deformation issues.  The only possible issue could be the temperature of the gasket, but it would be held in place by the clamped cover.  Have the gaskets had an issue with the deformed PVC boxes?
