Drone aerial thermal imaging: 2026 rates, anywhere in France
Drone thermography pairs a calibrated radiometric infrared camera with aerial mobility: in a single flight it reveals heat loss from a roof, insulation defects in a building envelope, failing photovoltaic panels (hot spots, blown diodes, dead strings), leaks in buried heat networks and water ingress beneath waterproofing membranes. Every pixel carries a usable temperature measurement, not just a colour.
Our thermal flights respect proper measurement conditions (indoor/outdoor temperature differential, absence of direct sun where required, humidity) and are paired with visible imagery to locate each anomaly. The report, produced in radiometric software by an operator trained in building thermography, locates and quantifies every defect. It is the reference tool for energy audits, photovoltaic plant operation and large-scale leak detection.

Rates
€500–1,800 per job — the 2026 French market range. The quote depends on the site, the expected deliverable and the local airspace context.
Common use cases
- Thermal inspection of a ground-mounted or rooftop photovoltaic plant
- Heat-loss audit of a commercial building or co-owned residence
- Leak detection on a buried district-heating network
- Detecting water ingress beneath flat-roof waterproofing
- Searching for people or animals (verification flights, fawns before mowing)
- Insulation checks before/after energy renovation works
Applicable regulations
Thermography follows the rules of the site being flown: open category A2/A3 for ground-mounted solar farms and buildings in clear areas (professional thermal drones usually exceed 900 g), specific category STS-01 with prefectural declaration for buildings in built-up areas. One specificity: building thermal flights are ideally flown at dawn or at night in winter, yet night flying is prohibited in the open category — it requires a specific-category authorisation or falls back on permitted dawn/dusk slots. Height under 120 m, AlphaTango operator registration, and particular care with parasitic reflections, which dictate controlled shooting angles.
Frequently asked questions
What time of year should building thermography be done?
From October to April, when the gap between the heated interior and the outside reaches at least 10°C. Flights take place early in the morning, before the sun warms the walls and skews the readings.
How much solar capacity can be inspected in one day?
An automated flight covers 10 to 20 MWp per day depending on the plant layout, with automatic hot-spot detection and each faulty module located by its coordinates.
Does the thermal camera measure exact temperatures?
Yes, provided a calibrated radiometric camera is used and material emissivity and ambient conditions are entered: typical accuracy is then ±2°C, sufficient for any building or photovoltaic survey.
