Need a Array Test for your own property? It's issued by the tradesperson who does the work — TradePlanr is the app they use.
The array test certificate records the DC test results for a solar PV array — the open-circuit voltage, short-circuit current, insulation resistance and polarity for each string — measured in accordance with BS 7671 Part 7-712.
TradePlanr captures the array and equipment details, the test conditions and instruments, and an unbounded schedule of string results, so you can document arrays of any size on site.

What it covers
- Module make, count and total array power
- Inverter and mounting details, and the MCS certificate number
- Test conditions: irradiance and module temperature
- The DC insulation test voltage and the test instrument
- An unbounded schedule of per-string results: Voc, Isc, Vmp, Imp, insulation and polarity
When it's required
The DC array tests are carried out at commissioning of a solar PV installation, and again where an array is investigated or extended.
This certificate records those string test results as a standalone document that accompanies the commissioning certificate and BS 7671 EIC.

Frequently asked questions
Can I record more than one string?
Yes. The string schedule is unbounded, so you can record every string on the array and they paginate cleanly across the PDF.
