Solar PV Installations & EICR's

I'd be interested to hear how others are handling solar PV installations as part of an EICR, especially the DC side.

The AC connection to the inverter is relatively straightforward to include, but the DC wiring, roof array, connectors and DC isolators are more challenging, particularly where access is limited or the inspector does not have specific PV competence.

The question was prompted by recent press reports of a school fire where the solar installation was reported as a possible cause. The system was said to have been installed around 10 to 12 years earlier, so in theory may have been through more than one periodic inspection cycle.

So, in practice:

Do you include the PV DC side within the EICR, or limit the inspection to the AC supply circuit and inverter connection?

If excluded, how do you word the limitation?

Would visible PV defects still be coded if outside the agreed scope?

Where roof access is not available, do you recommend a separate specialist PV inspection?

And more broadly, should PV systems have their own defined periodic inspection regime, especially on schools, commercial buildings and higher-risk sites?

I’m interested in how this is being handled in the real world, because there seems to be a possible gap between a building having an EICR and the PV system being meaningfully inspected.

  • From October 2026, if you are a member of a CPS and you are involved in solar PV or battery installations, you will need to have the relevant Electrician+ qualification. If you do not, you will not be able to demonstrate appropriate competence. The reasonable implication would seem to be that if you do not hold these qualifications that cover design, installation, commissioning, inspection and testing, you could not demonstrate competence if you are carrying out a periodic inspection of such systems.

    I guess it is a bit like not having formally recognised competence in understanding the requirements of 7671. One might conclude that you can hardly be formally recognised as competent to carry out periodic inspection activity of any type of installation within its scope.

    We make it abundantly clear under the Extent and Limitations section on the EICR that the scope of the inspection specifically excludes all parts of the solar PV and battery system.

  • How does Electrician+ fit in with MCS certification please?

  • Good question Chris, really not sure, but the OP didn’t limit his question to small scale PV. Many of our inspections would be for clients who may have hundreds of Kw, multiple inverters, complex gateway and usage controls. 
    I think GTB has summed up my approach in terms of the statutory considerations. Of course, those statutory requirements also demand that operatives need to be competent. An aspect of competence is knowing one’s limitations. Pulling it all together is why we make it explicit in the extent and limitations section of the EICR that no part of the PV system falls within scope. 
    The client will need to exercise his statutory duty in relation to the PV system by employing an enterprise that has appropriate expertise in that area.
