SWA cable

[xcentric]

Can I use 6mm2 SWA cable to take the DC output of my panels from one end of the house to the inverter - or are dedicated solar DC cables better? Looking for cost-effective, safe, solution - panels are on one roof and cable has to pass over ridge, down other roof (however I can get it done, ideally internally but not simple) then across side of house to connection box..... recommendations for suppliers of well-priced cable welcomed too (UK).

for either SWA or 6mm2 solar cable.

thanks. Any preferences for which if burying to go from one part of house to another? Do both need conduit - I assume the SWA can be directly buried across the lawn?

I always use conduit and size it so extra cables can be fitted later and leave a pull cord in place.

that's what I've done in the past but slicing a thin trench through the lawn is much easier than a thicker trench for conduit. I assume there are regs for depth but I'll do 600mm or so. I don't expect to need another connection as it's from a roof to the garage. However, I could possible route it along the guttering across the house to a different location (I plan to have 2 inverters, but either way they are a long way from these extra panels - close to the main arrays tho).
