More than aerial images

Inspection data translated into maintenance intelligence.

A drone can collect imagery. ThermoSky adds the engineering context needed to understand what an observation may mean, how urgent it appears and what should happen next.

Findings are reviewed from an electrical engineering and asset-performance perspective—not presented as unexplained photographs.

Early fault detection

Identify abnormal heat patterns and visible condition concerns before they develop into larger maintenance problems.

Reduced inspection risk

Collect detailed data from difficult or elevated locations while reducing unnecessary exposure of personnel.

Faster asset coverage

Inspect extensive solar arrays and line corridors efficiently, subject to site and operating conditions.

Actionable reporting

Convert imagery into geotagged findings, priority categories and practical follow-up recommendations.

Solar PV thermography

See what ordinary imagery cannot show.

Thermal imagery can reveal temperature differences across modules and components. These patterns are reviewed alongside visual evidence and operating context before follow-up is recommended.

A thermal anomaly is an observation—not automatically a conclusive diagnosis. Further electrical or physical investigation may be required.

Power line inspection

Better visibility of assets that are difficult to access.

Drone-based thermal and visual inspection can support the review of line hardware, conductors, insulators, structures and vegetation conditions while reducing unnecessary work at height.

Temperature anomaliesCompare joints, clamps and connectors under relevant operating conditions.

Visible condition concernsReview insulators, fittings, corrosion indications and mechanical irregularities.

Vegetation and accessRecord encroachment or corridor conditions for targeted management.

Prioritised follow-upOrganise observations by asset, evidence and maintenance significance.

How it works

A clear path from asset concern to practical decision.

Every project is planned around the asset, the inspection objective and the information the client needs to act.

Consultation

Understand the asset, inspection objective and operational concerns.

Inspection planning

Review the site, flight area, safety conditions and required outputs.

Drone data collection

Capture thermal and high-resolution visual data safely and efficiently.

Engineering analysis

Compare patterns, review anomalies and classify findings for follow-up.

Technical reporting

Provide geotagged evidence, priorities and recommended next actions.

Review the full inspection process

Inspection deliverables

Clear findings. Practical decisions.

Reporting is structured to help technical and management teams understand the evidence, locate the asset and plan the next action.
