Solar panels being inspected by a drone

Solar farm drone inspection Full-site thermal fault detection for utility-scale solar farms. Pre-construction topographic mapping for solar developers.

Thermal coverage of the entire site. Panel-level GPS references for every fault.

A large utility-scale solar farm may have tens of thousands of panels — a ground inspection team can take weeks to survey the full site manually, and many faults are invisible to the naked eye. Our thermal drone surveys cover the entire site in a single sortie, without removing or de-energising a single panel. Every fault — hotspot, bypass diode failure, string underperformance, soiling pattern — is captured in flight and delivered as a georeferenced, annotated fault map your maintenance team can act on directly.

Thermal fault detection

Hotspots, bypass diode failures, and underperforming strings are invisible to the naked eye under normal operating conditions. Our drones carry thermal imaging cameras that detect heat anomalies across every panel in a single sortie — identifying failing cells and components before they cause measurable production losses. The thermal survey runs alongside the visual inspection with no additional flight time and no panels removed or de-energised.

Full site covered in a single sortie

A large utility-scale solar farm may have tens of thousands of panels. A ground inspection team covering the same site manually can take weeks. Our drones survey the full array in a single flight, capturing thermal and high-resolution visual data simultaneously — with no downtime, no scaffolding, and no interruption to generation.

GPS-tagged, audit-ready records

Every fault is GPS-tagged at the point of capture and referenced on a full-site orthomosaic. The output is a panel-level annotated fault map — your maintenance team can locate any identified fault in the field without guesswork. The same dataset provides a timestamped baseline record of your array’s condition for performance monitoring, warranty claims, and insurance purposes.

Pre-construction mapping for solar developers

Before a solar farm can be designed, developers need accurate topographic and photographic data of the proposed site. This feeds directly into specialist solar design CAD software for panel placement, shading analysis, sun angles by season, and site suitability assessment. We produce a survey-grade orthomosaic, Digital Elevation Model, and Digital Surface Model in a single flight — with all site features (trees, hedgerows, walls, buildings, watercourses) captured and positioned to survey accuracy.

Why use drone inspection for solar farms?

No panels removed or de-energised

The array stays live throughout the inspection. No panels are removed, tilted, or shut down — which matters because faults are only visible at operating temperature.

Thermal and visual in one flight

Thermal imaging detects hotspots, bypass diode failures, and string faults invisible to the naked eye. Visual RGB captures physical damage. Both run simultaneously in a single sortie with no additional flight time.

Entire site covered in one sortie

Tens of thousands of panels surveyed in a single automated flight — what a ground team might take weeks to cover is completed in a day, with no downtime and no interruption to generation.

Panel-level GPS references

Every fault is GPS-tagged at the moment of capture and referenced on a full-site orthomosaic. Your maintenance team can locate any fault in the field without guesswork.

Fault classification report

Faults are classified by type and severity — hotspots, bypass diode failures, string faults, soiling, physical damage — giving your team a prioritised maintenance schedule.

Pre-construction surveys for developers

Solar developers need accurate topographic and photographic data before design can begin. We produce a survey-grade orthomosaic, DEM, and DSM in a single flight, ready for solar design CAD software.

A single sortie covers the entire site

A large utility-scale solar farm may have tens of thousands of panels. Our drones capture thermal and high-resolution visual data across every panel in a single automated flight — producing a full-site thermal orthomosaic that your maintenance team can use to locate every fault to within centimetres, without a ground crew covering the field.

What the data enables

The delivered thermal orthomosaic and annotated fault map contain panel-level GPS references for every identified fault. Your maintenance team can locate each fault in the field without guesswork. Faults are classified by type and severity — hotspots, bypass diode failures, string faults, soiling, physical damage — giving you a prioritised maintenance schedule. The same georeferenced dataset provides a timestamped baseline record for ongoing performance monitoring, warranty claims, and insurance purposes.

A complete, structured evidence package

Every inspection delivers a thermal orthomosaic of the full site, an annotated fault map with panel-level GPS references for each identified fault, visual imagery of flagged panels, and a fault classification report — ready to hand directly to your maintenance team, and suitable for warranty claims and insurance purposes.

Pre-construction mapping for solar developers

Solar design CAD software needs both an accurate overhead orthophoto and elevation data before panel placement, shading analysis, or site suitability assessments can begin. Photogrammetry delivers both in a single flight — a survey-grade orthomosaic, Digital Elevation Model, and Digital Surface Model, with all site features (trees, hedgerows, walls, buildings, watercourses) captured and positioned to survey accuracy. We liaise directly with landowners to confirm access, and large rural sites typically operate under Open Category rules with no special permissions required.
