A thermal camera flown over a solar array resolves individual panels well enough to tell a failed component from a simple patch of soiling.
The thermal imagery is processed into a georeferenced map and joined to standard photography from the same flight, so every anomaly is identified by its position in the array rather than by a frame number.
Conditions are part of the spec
Thermal results are only meaningful in the right weather: strong sun, light wind and a stable array. We record the site conditions throughout the flight and publish them with the results, because a thermal report without them cannot be defended.
Findings
Anomalies are classified by severity and type, tabulated with coordinates and module references, and delivered with the imagery so your maintenance team can re-check any of them.
