The challenge

Sensor data from solar plants overwhelmed a single database outside the EU, and faults were spotted days late.

What we did

  1. Moved the platform to an EU cloud region with a time-series data store built for the load.
  2. Added fault detection that flags underperforming panels within minutes.
  3. Gave site owners a dashboard of yield, faults and savings.

The results

50×More sensor data handled
