Guidance for plug in solar for Electricians

We are now a few days from plug in solar being legal. The likes of Martin Lewis is recommending people should ask an electrician to check their installation before plugging a solar system in.

I have seen various comments referring back to changes in the law and changes to the specification for a 13A plug.

But I haven't seen any guidance from IET, NAPIT or NICEIC for electricians stating under what conditions it's acceptable to plug one of these systems in.

Personally as it stands today based on what I have seen I would not be willing to say iny installation is acceptable unless it was a single socket on it's own circuit protected by a bidirectional type A RCBO. Which I am sure isn't what the government wants.

Have I missed something, is something in the pipline?

I know lots of people will just do it, but in those situations I am not responsible.

  • Anyone feel confident enough to do a PAT inspection and test on a plug in PV unit, and then certify it as safe to use and attach a sticker to it with your contact details on it?

  • Well I probably would, assuming it looked like mounted for no water ingress, and mechanically OK, albeit I'd skip any hi-pot test. But then for work I'm fairly used to signing off on the manufacturing end of CE marking and similar def-stan paperwork for things I have designed.  My outlook on 'reasonable levels' of product safety is perhaps a bit different.
    Being more than half outdoors I'd suggest a short ( 1 or 2 year) retest interval.

  • So you’re going for visual only?

  • Apologies if it was not clear -  vis + earth bond + 500DC L+N to E, no Hipot insulation tests.
    Mind you if it was on the eaves of the house and out of reach, maybe visual is good enough.
