IMO they have no intention to ever install those panels, just using them to keep naive shareholders happy to continue this dump fest... They have sold 46 Million shares per day for the last 3 months... That's 4 BILLION shares added to the A/S..
They are polyfoam filled which won't get damaged if it gets wet and the walls are aluminum not steel. They are light in weight and very easy to install. Used this type of panel on a project already.
