[ For EPC Contractors ]

You Built It. Now Prove It.

Commissioning ends. Disputes begin — unless every module is documented.

SunSniffer is not sold here as a monitoring tool — it is sold as commercial protection built into the commissioning process: timestamped handover evidence.

The conventional handover gap

A folder of PDFs is not a living performance baseline.

“But we already document everything.” The facts side by side tell a different story.

* IEC 62446-1 requires string-level commissioning test records. SunSniffer exceeds this by delivering verified module-level baseline data at handover.

02
How it works

From first module to full digital twin — in one commissioning process.

SunSniffer does not add work to the commissioning process — it digitizes the process that already happens.

STEP 01
Factory pre-pairing
Sensor integrated into the junction box at production. Paired to the module serial number before it leaves the factory.
STEP 02
Barcode scan at install
Installer scans each module as it goes on the roof or racking. The scan writes exact position into PlantView.
STEP 03
Wrong-position alerts
If a module is in the wrong string or wrong position, the portal flags it on-site — before handover.
STEP 04
First clear sky day · TrueSTC
STC-equivalent performance baseline calculated automatically for every module. Timestamped.
STEP 05
Digital Birth Certificate
Deliverable handed to the asset owner: every module named, positioned, and baselined.
03
Three deliverables

Three deliverables. One handover. Zero grey areas.

Concrete, actionable, complete. Each one addresses a specific risk the EPC faces.

Instant String Validation
Every string and monitored module is compared during commissioning with its TrueSTC baseline. Any module crossing the configured performance threshold is identified for review before handover — while the crew is still on site and can act on it.

Digital Birth Certificate
A permanent record of every module at commissioning: serial number, physical position, and verified STC performance baseline. Timestamped handover evidence — for owner, EPC and insurer alike.
✓closes: baseline & position disputes

Zero-Dispute Handover
You hand over a live digital twin, not a folder of PDFs. If performance drifts later, the owner can see exactly when and which modules — and it will not be your commissioning work that is in question.
✓closes: liability for post-handover drift
Bridge to operations

The plant you hand over keeps working for you.

The Digital Twin you create at commissioning does not stop at handover. It becomes the operational baseline for every future maintenance decision.
