Everything downstream — every diagnosis, every plan, every euro — stands on measurement, not estimation. Four layers carry the signal from the junction box to the answer.
Voltage + temperature of every module, every 15 seconds — from inside the junction box.
U + T · 15 sReads all module signals over the DC line, samples string current 16× per second, hears DC arcs.
I · 16 HzMoves the plant data to the cloud. Dual-processor watchdog — it restarts itself, not your visibility.
uplink · 24/7TrueSTC™, DiodeVital™, LossTrace and PVLib run on every reading — continuously, automatically.
5,760 pts / module / dayThe inverter reports one number for a hundred modules or more — never grounded against irradiation and temperature. You see production is down, but not which modules, and not whether fixing them pays. SunSniffer turns that one number into a decision, in three steps:
One number for the whole MPP input. Production is down — that is all it says.
Every module measured, every 15 seconds — each loss gets a place and a size, whatever the cause: soiling, cracks, diodes, PID, hotspots.
Losses grouped, priced against your 20% ROI rule — act, or leave it.

In a published Helmholtz comparison, power-loss estimates from thermography carried 8.3% uncertainty — electrical losses below 5% were not reliably identified. Teubner et al. (2017), Energy Procedia 124
Four engines turn every module signal into evidence: what it delivers, whether it is safe, what the weather allowed, what each loss costs.
Ask in plain language — a performance summary, a warranty report, a portfolio overview. Every answer traces back to a measurement, so you check the trail instead of trusting a feeling.
Findings are labelled in IEA PVPS Task 13 fault categories — a shared language for operators, manufacturers and insurers. Read the science →
This is the beauty of measuring every module: every loss comes with a location, a magnitude and a history — and a financial impact. Ray — the AI analyst inside the portal — turns that evidence into prioritized work, and the ROI planner checks each action against your economic threshold.
Ask in plain language — no dashboards to learn, no diagnostic trip just to find out where the loss is. Field work starts with a prioritized target; targeted inspection is added where cause, safety or warranty requires it.
