A radiometric thermal payload paired with a visible camera on the same flight — surfacing heat-loss, trapped moisture, failing solar strings and overheating components, ranked and explained.
What it covers
- Heat-loss through insulation gaps and thermal bridging
- Trapped moisture under flat-roof membranes
- Failing strings and hot cells on solar PV arrays
- Overheating electrical components and connections
- Damp ingress patterns on elevations
- Visible + thermal pairs, side by side
What you get
- Paired visible and radiometric thermal frames
- Marked and ranked temperature anomalies
- An annotated PDF with plain-English findings
- Full-resolution archive of all captures
- Clear limitations (weather, surface, time-of-day)
Who it's for
Energy assessors, facilities and maintenance teams, solar O&M, and property owners diagnosing damp, heat-loss or PV underperformance.
Compliant by default
Every flight is planned and flown under Recon's CAA Operational Authorisation, with A2 CofC / GVC qualified piloting, CSCS site readiness and £5M public liability cover. Each job is scoped against airspace, access, weather and permissions before we commit to a date.
Common questions
What can a thermal drone survey detect?
Radiometric thermal imagery surfaces temperature anomalies that often correlate with heat-loss, trapped moisture under flat-roof membranes, failing solar strings and overheating electrical components. We mark and rank the anomalies; a specialist diagnosis on site confirms the cause.
When is the best time for a thermal survey?
Thermal contrast is clearest when there is a temperature difference between inside and outside, and away from direct midday sun heating surfaces. We plan the flight window around weather and time-of-day for the most reliable readings, and note any limitations in the report.
