Estimated lost production: 3,287 kWh
Your system may already be losing production. You might only find out weeks later.
A stopped string, abnormal inverter value or gradual performance decline can silently remove energy that could have been produced. Sentinel monitors, remembers and alerts.
The calculator provides an indicative estimate based on your inputs.The cost begins when production starts to fall.
The system may appear operational while the deviation grows day after day in the background.
- 01Operational deviation
A string, inverter or data connection starts behaving abnormally.
- 02Hidden production loss
The system continues running but no longer delivers its potential output.
- 03Lost energy
Energy not produced today cannot be recovered later.
- 04Financial impact
Missing energy must be purchased from the grid.

Estimated lost production: 640 kWh
This is an indicative seasonal estimate. It allocates 42% of annual production to summer, 8% to winter and 50% to spring–autumn. Actual production depends on weather, orientation, shading, the consumption profile and individual settlement terms.
The production curve is only the end of the story.
Sentinel stores not only how much the system produced, but also the available AC, DC, string, temperature, status, fault, communication, weather and sensor data.
“Manufacturer monitoring shows how much the system produced. Sentinel remembers how it operated.”
Operational history may also help reveal a possible cause of a deviation in certain cases.
Data only creates value when a deviation is noticed.
Primarily focuses on displaying production
Preserves a more detailed operational history
The user must check the portal regularly
Automatically monitors incoming data
Usually tied to one manufacturer
Can handle data from different manufacturers consistently
Technical interpretation may be left to the customer
Turns defined deviations into communicated alerts








Who bears the cost of late detection?
When your system produces less, your company buys more electricity from the grid.
Sentinel helps make deviations visible earlier without requiring constant manual portal checks.
Start registration →An institutional energy investment can lose output while appearing to operate normally.
Sentinel helps make deviations visible earlier without requiring constant manual portal checks.
Request consultation →A running inverter does not necessarily mean the system is producing as it should.
Sentinel helps make deviations visible earlier without requiring constant manual portal checks.
Start registration →See which site needs attention without checking separate manufacturer portals.
Sentinel helps make deviations visible earlier without requiring constant manual portal checks.
Partner consultation →An alert, not a false sense of security.
Sentinel evaluates incoming data and communicates an alert when a defined condition is met. This indicates that the system may require attention or further investigation.
- 1Data collection
Operational data is received and preserved.
- 2Deviation detected
A defined alert condition is met.
- 3Notification
Sentinel communicates the condition requiring attention.
- 4Further action

Sentinel supports earlier detection; it cannot guarantee that every fault is prevented.
Historical data may help investigation, but expert diagnosis is a separate service.
