What should a solar PV commissioning sheet include?

For each string: module quantity and rated Voc and Isc, protective device and cable details, measured Voc, Isc and irradiance, a polarity check, insulation resistance positive and negative to earth with the test voltage, earth continuity where fitted, and array isolator and inverter checks with the inverter's make, model and serial number.

Last updated . Facts checked on 30 September 2026 against MCS: MIS 3002 Issue 6.0, The Solar PV Installation Standard (18/03/2026).

Who uses it

The commissioning engineer or electrician testing a PV array, one sheet per string or per inverter.

When

At initial verification after installation, and again at periodic inspection or after a string is repaired.

In Integrio

Build it once in the Form Builder (Office User), attach it to projects, and your team fills it in on iOS or Android, offline if needed.

From the field

How do you get the most from a solar pv commissioning sheet?

01

Record irradiance with every Isc

Isc moves with the sun. A reading with no irradiance next to it can't be compared with the rated figure, or with the same string next year.

02

Compare strings, not just limits

On a commercial roof, identical strings should read alike. A string reading well below its neighbours points to a wiring or module problem in that string; find it before the scaffold comes down.

03

Tie the sheet to the inverter serial

Store results against the inverter and string reference, not just the job. When an O&M ticket comes in years later, the baseline readings are one tap away.

04

Fail it properly

If a reading fails, record what was found and what was done, then retest on a fresh sheet. Overwriting a failed reading hides the history the next engineer needs.

Frequently asked questions

What do people ask about the solar pv commissioning sheet?

Ask our team →

What tests does MCS require for solar PV commissioning?

+

MIS 3002 says the system is commissioned to a documented procedure and inspected and tested to Section 16 of the IET Code of Practice for grid-connected solar PV (excluding 16.4). Its Appendix E model array test report, adapted from BS EN 62446-1, records Voc, Isc, irradiance, polarity, insulation resistance and isolator and inverter checks for each string.

Sources: MCS: MIS 3002 Issue 6.0, The Solar PV Installation Standard (18/03/2026), IET: Code of Practice for Grid-connected Solar Photovoltaic Systems, 2nd Edition

Is this the same as the BS EN 62446-1 test report?

+

It covers the same readings as the model array test report that MCS reproduces from BS EN 62446-1, laid out as a mobile form. IEC 62446-1 also covers inspection criteria and the documentation handed to the customer, so keep the standard itself for the full procedure.

Sources: IEC 62446-1:2016, Grid connected PV systems: documentation, commissioning tests and inspection, MCS: MIS 3002 Issue 6.0, The Solar PV Installation Standard (18/03/2026)

Does this replace the electrical installation certificate?

+

No. This sheet records the PV array tests. The AC side still needs its BS 7671 certification, and the DNO and MCS paperwork is separate.

Is this solar PV commissioning sheet free?

+

Yes. Use the fields on paper, in a spreadsheet, or set it up in Integrio as a testing form on each inverter.

How do I use this template in Integrio?

+

Build it once in the Integrio Form Builder, which is on the Office User plan (£65 per user per month), and attach it to the inverter product so every unit gets the same test form. Engineers fill it in on the mobile app on the Field Service User plan (£15 per user per month), offline on roofs with no signal.
