Consultation Announcement: Solar PV Installation Standard

MCS have today published a one-month consultation on changes to our installation Standard for Solar PV systems (MIS3002).

This new draft of MIS3002 adopts the IET Code of Practice for the installation of Solar Photovoltaic Systems, but fills in gaps and re-enforces certain requirements. It also incorporates the energy performance method from the old guide but separates the shade assessment into a new guidance document MGD005.

This shade assessment method has been known to have practical issues and so is now optional such that MCS Certified Installers can use other shade assessment methods, provided they are no less valid.

We are also interested in suggestions for other simplified shade assessment methods which could be adopted instead of that within MGD005. Any such methods should not be reliant on proprietary software packages as it would not be appropriate for MCS to adopt or endorse software from any one particular vendor.

MCS would like to invite comments from stakeholders.

The deadline for submitting comments is Friday 15th May 2020.

Please send consultation responses to using the form provided.

Until the submission deadline, the IET will provide stakeholders with free online access to the ebook of their Code of Practice for Grid-connected Solar Photovoltaic Systems. Access or additional information can be requested by contacting the IET directly at: (Please note: access requires the creation of a VitalSource account.)
