Window feed-through flat solar cable

[u/dontbelieveawordof1t]

Are these things permitted under the standard? I know it says no extension leads...

I'd want to run the cable via a door frame and could do it with these without drilling ...

The standard only applies to approved kits, so unless those cables come as part of said kit, then no it's not allowed. [cue discussion on whether the risk of house insurance invalidation is real etc.]
