You fly the drone. We report the findings.

Solar PV Array Inspections

String-level faults, bypass diode activation, hotspots and shading losses, with DTAT spot-temperature quantification and a severity rating on every finding.

THERMAL + RGB

What we check for

Cell, substring and module-level hotspots
Bypass diode activation patterns
String and section-level thermal elevation consistent with electrical faults
Shading losses from vegetation, plant or adjacent structures
Cracked, delaminated or physically damaged panels (RGB)
Junction box and connector heat signatures
Soiling and general array condition

An example of what you get back

Every finding in every report follows the same structure — location, frame reference, affected area, confidence, probable cause and recommended action, rated Red / Amber / Green. Here's a worked (illustrative) example from this survey type.

Finding 1: Array Section — Section-Level Thermal Elevation

Location	East array, columns 4–7
Frame reference	0006_T / 0006_RGB
Estimated affected area	Multiple panel columns; estimated 20–40+ panels
Confidence	Moderate-to-high
Severity rating (RAG)	AMBER

Observation: A distinct section of the array shows consistently elevated thermal signatures compared to an immediately adjacent section which reads cool. Both sections appear visually identical in the corresponding RGB imagery — no damage, soiling, or shading.

Probable cause: On balance of probability, a string-level or circuit-level electrical issue causing this section to generate little or no electricity.

Recommended action: String-level electrical inspection, including string open-circuit voltage and current measurement. Priority finding.

How the RAG rating works

Every finding on every survey type is rated against the same published definitions, so a Red on one job means the same thing as a Red on the next.

● RedA live risk of water ingress, structural risk, or a safety hazard — flagged for prompt action.

● AmberLikely to progress to failure if left unaddressed, but not currently causing a problem.

● GreenCosmetic or early-stage — worth recording, not urgent.
