Detecting Progressive PID Degradation Before It Reaches String Level
A solar asset owner suspects potential-induced degradation across older arrays but cannot confirm it without invasive testing at scale.
Run on Wayam Eye · Renewable Performance

The challenge
PID develops progressively and is invisible in generation data until it is already significant.
Confirming PID conventionally requires taking strings offline for electrical testing.
Without early confirmation, remediation decisions are made too late to be economic.
How Wayam Eye solves it
Repeat Capture Comparison
Successive thermal captures of the same modules are compared over time rather than assessed individually.
Progression Detection
Modules showing consistent thermal signature drift are flagged before they reach conventional fault thresholds.
Pattern Correlation
Degradation patterns are correlated across strings and inverters to distinguish PID from isolated failure.
Remediation Scoping
Affected areas are quantified so mitigation is scoped against a known population.
Ongoing Monitoring
Flagged areas are tracked across subsequent captures to confirm whether mitigation held.
The outcome
Progressive degradation identified before it reached string-level generation loss.
Confirmation without taking strings offline for electrical testing.
Remediation scoped against a measured rather than an estimated population.
Representative scenario: a modelled industry situation showing how this accelerator applies. Figures are projections, not a named client result.
Capabilities used
Every accelerator is assembled from the same capability layer, so a workflow you adopt here shares its foundation with the rest of the portfolio.
