Can you bury SWA cable with DC solar power ???

We get into the regulations and rules regarding DC distribution on PV systems. Using our views and experiences as installers and designers. But we want to know what others think about the new innovation from  @Doncaster_Cables . Do you think it can be buried direct? Does it need the armours earthing? Can we blend ADS and other protective measures. Should we mix AC system earths into DC distribution? Is this cable type even needed? Get involved in the comments
