Plug in solar

But if they are currently certified for UK use (wired to CU or spur on circuit), then I don't see what change there will be.

I appreciate that illegal/un-certified kit may be offered (and has been for small plug in systems for ~15yrs, typically claiming meters will spind backwards and save you money), but that is totally different to the current kit that is available today …… just without a plug fitted on the end of the wires (if for delivery in the UK).

Wiring to a spur wouldn't in itself comply with the current requirements for "normal" solar.

I thought that was OK, so long as there are no other sockets on the circuit (but wired through a spur, not a conventional plug)?

The point being that the kit is certified for UK use, but the UK is looking to widen the approved uses.

If there are no sockets on the circuit yes that could comply if the breaker is suitable. Correct RCD type, bi-directional, switching both L and N, no other upstream or shared RCD, lockable two pole isolator. Not sure I'd call that a "spur" though.

I said spur, as my understanding is that whilst normal PV can be connected to an appropriate circuit with no other sockets, it can't be 'plugged' into a socket.

In that example, the changes in regs would (simply put) mean that the PnP PV could be plugged into a socket on that circuit, and there could be other sockets.

So back to the original point, kit with UK certification, will be allowed as the UK is looking to widen the approved uses.

• Rooftop solar panels are already saving families up to £480 a month

Surely a typo somewhere there…….

Qyburn

Accepting that it's draft, there are a few interesting points in the specification ("Plug-in Solar Device Interim Product Specification"). My interpretation on a fairly quick skim.

5.7 (p20) "The device shall be designed such that it does not adversely affect the operation of upstream
residual current devices." Does that means it must be shown not to introduce the sort of DC leakage that screws up Type AC RCDs?

7. (p27) As well as being compliant with requirements of G.98, the specific device needs to be listed on the Type Test Register.

In various places it refers to the possibility that multiple systems might be permitted.

Does not cover any form of battery.

Will there be a small surcharge to cover the possibility of fire or the panel flying off and whacking something or someone, bunged into an insurance fund?

Ah, the old "up to" routine.

Of course, the "saving" has to be offset against the cost of the install.

A system saving £480/month would not have been cheap.
