01Actual energy
Interval power integrated over valid elapsed time, or validated interval energy when supplied. Invalid and duplicate measurements are flagged rather than silently included.
Analysis methodology
Every KPI should be traceable to inputs, rules, and uncertainty.
These definitions describe ArraySignal’s analytical intent. Model version, site configuration, evaluation range, and quality findings are part of the result—not hidden implementation detail.
02Expected energy
A versioned, weather-adjusted physical model based on site configuration and model-ready weather inputs. Calibration is explicit and retained in provenance.
03Energy deficit
The nonnegative difference between eligible expected and actual energy. Missing telemetry is separated from measured underproduction.
04Performance percentage
Actual divided by expected for eligible energy, with divide-by-zero returning unknown instead of an artificial percentage.
05Availability
The share of eligible daylight intervals in which the system is considered available under the configured evidence rules.
06Data coverage
Valid observed intervals divided by expected intervals for the requested range, including explicit missing, duplicate, and invalid findings.
07Component comparison
Capacity-normalized component performance relative to comparable peers and periods; sparse components are not ranked as precise results.
08Health score
An explainable composite of performance, availability, data coverage, and qualified issue severity. The contributing deductions remain visible.
09Modeled lost energy
Estimated forgone energy only where expected production and data quality support inference; uncertainty is retained.
10Estimated revenue impact
Modeled lost energy multiplied by an explicit configured energy value. It is not a guarantee of recoverable savings.
