Commercial & industrial · Drone thermal inspection

Drone thermal inspection of commercial solar arrays: every module, from the air.

Infrared (IR) thermography by drone, with radiometric capture across every module. Hot cells, failed bypass diodes, bad connections and dead optimizers show up as temperature deltas long before production data notices.

Nationwide, 500+ technicians. All 50 states covered.

Small losses hide well

A string at 2% loss disappears into weather variance in production data and shows up unmistakably in infrared thermal imagery.

1

At commissioning

The baseline. Defects found at commissioning are the installer's to fix. Defects found in year three are yours.

2

Warranty windows

A defect documented while the warranty is live is the manufacturer's. Timing is most of the value.

3

Ongoing

Periodic sweeps catch new faults and show which old ones are progressing.

How a drone thermal sweep works

1

Baseline

Inspect at energisation so handover defects stay with the installer.

2

Sweep

Aerial drone thermography: radiometric capture across the whole array.

Work order

Findings classified, located and prioritised.

What you get back

Questions about drone thermal inspection

What does a drone thermal inspection find?

Hot cells, failed bypass diodes, bad connections and dead optimizers. They show up as temperature deltas in radiometric infrared (IR) imagery long before production data notices.

Is every module inspected, or a sample?

Every module is inspected, not a statistical sample. Capture is radiometric and runs across the whole array.

What do we get back?

Radiometric infrared thermal imagery of every module, a geolocated aerial thermal orthomosaic, defects classified by type and severity with module-level location (row and position), and a prioritised remediation list. Repeat sweeps add a comparison against prior sweeps.

When should an array be flown?

At commissioning, as the baseline, so handover defects stay with the installer. Again while the warranty is live, because a defect documented in that window is the manufacturer's. Then periodically, to catch new faults and show which old ones are progressing.

How does this relate to the thermal inspection page and electroluminescence?

The thermal inspection page covers infrared solar panel inspection in general; this page is about the drone sweep itself. Thermal imagery shows faults as heat, while electroluminescence finds cell-level cracks before they show.
