Digital Twin — satellite monitoring with smart calibration

With version 1.3.0, Sunnix introduces digital twin monitoring: a mathematical model of your system, automatically calibrated on your real data, that compares expected vs actual production every day. If something is off, you receive an alert with the probable cause (soiling, hardware fault, weather, curtailment) and estimated financial losses.

Automatic calibration by weather regime

The system analyzes the production history you upload and calibrates the model separately for sunny, mixed, and cloudy days using a Kalman filter. The more data you upload, the more accurate the estimates become.

Three independent calibration factors (sunny, mixed, cloudy) for maximum precision
CSV upload with daily kWh from your inverter — one-click calibration
Anomaly detection with 3σ threshold: only real alerts, no false positives from bad weather
Automatic cause diagnosis: soiling, hardware fault, curtailment, or weather
