Our expertise

The different application areas of aerial thermography

Heat network thermography

Since 2014, we have inspected more than 200 km of heat network by drone. Primary, secondary, gutter, pre-insulated, HP, BP… In France and abroad.

Photovoltaic park thermography

We inspect solar power plants from 50KWH to 100 MWH. From the simple roof to the park of several hectares through the agricultural roofs.

Building thermography

Identification of thermal anomalies specific to building pathologies. Collective, individual and industrial. Thermal bridges, degradation or lack of insulation.

Industrial thermography

Thermal inspection without production stoppage. No human commitment. Aerial thermography on sensitive sites: SEVESO, nuclear, army… Team trained in industrial risks.


Thermal inspection process



Characterisation of your inspection expectations and definition of rendering.

On-site capture

Creation of a secure area, flight plan, aerial thermography, customer video feedback.


Exploitation of renderings

Post-inspection meeting. Exchange on the use of renderings.

The prerequisites for each subject

Certain meteorological conditions must be respected to ensure a reliable thermal inspection : sunshine or cloud cover, humidity, wind, outside temperature and the temperature of the subject.

Questions about your subject to thermograph?

Our thermal inspections and reports also consider the following :


  • 5The emissivity of the inspected material
  • 5The nature of the surfaces
  • 5The thermal sensitivity of the camera
  • 5Thermal conductivity
  • 5The inspection angle relative to the observed surface

The conditions of the thermal inspection

In the case of aerial thermal inspection, each subject requires its own capture methods and conditions.

A thermal inspection of solar panels

will require clear skies, clean panels, and maximum sunlight so that the plant produces at least 70% of its capacity.

Aerial building thermography

is carried out at night, so that the sun does not imprint the facades. The building must be heated to increase the difference between the outside and inside temperature.

Learn more about building thermography >>

The thermal inspection of heat networks

is carried out during winter periods with maximum load on the network. The outside temperature should not exceed 10°.

Frequently Asked Questions

What do your thermal reports look like?

Our thermal reports evolve according to your expectations and the subjects to be inspected. During the first customer exchange, we define with you what is most useful to you and we adapt the results accordingly. The mobility of the drone allows us to perform a fast and complete thermal scan. We combine our know-how with that of a doctor in thermography to define a capture strategy and offer a calibrated and usable rendering. For the aerial thermography of solar panels, we provide a thermal map of the plant in PDF and TIFF format with the various defects identified and positioned. Learn more about photovoltaic power plant inspection. For building thermography, we provide a PDF report of the various defects listed and analysed in order of priority. These faults are also geolocalised on a map. Learn more about aerial building thermography. Rendu thermique de qualité

What thermal camera do you use?

Working on major projects in the field of aerial thermography, such as the scanning of 250 homes for GrDF, or the inspection of 75,000 photovoltaic panels for Akuo Energy, has enabled us to improve our acquisition processes and our know-how.

Caméra thermique

To guarantee optimal quality and a high-resolution image, we are equipped with the Flir XT2 thermal camera, which has the most efficient onboard thermal sensor on the market (640 x 512 pixels) and offers a thermal sensitivity of 0.04 °C.

We have an RGB sensor coupled with the thermal sensor, which allows to compare the thermal image with a real photo and thus have more details of the subject to be inspected.

How is aerial thermography performed?

Schéma de déroulement d'une thermographie aérienneWe plan our flight plan and adapt our aircraft to different projects depending on the subject to be thermographed, the location, the area to be covered and the time of year. We use two capture modes depending on the applications. During the thermography operation, our onboard measuring devices record the thermal image as well as a digital photograph serving as a reference. The point of view chosen for the thermal measurement is immediately identifiable and allows to accurately validate the covered space and the defective zones (thermal bridges, missing insulation, energy-consuming zones). Thermographie d'un bâtiment, vu des fenêtres sur un thermogramme The choice of a thermographic video capture is suitable for the inspection and detection of heat leaks on large surfaces. Once the leak has been detected, the photo takes over to record a geolocated thermogram of the area of ​​interest, allowing precise analysis.

Who takes care of the thermal data acquisition?

The StudioFly Technologie team dedicated to aerial thermography by drone is made up of a remote pilot operator and an engineer. This team carries out the follow-up of the operation, the scan, the reading of the data on the ground, as well as the diagnosis necessary for the interpretation of the thermograms. Thermographie d'un immeuble We couple our thermal camera to a video feedback, ensuring a pre-rendering to guarantee the quality of the capture. The drone inspection of a building is done in a few minutes and our operator can thus carry out several dwellings or buildings per flight. Our drone thermography solution, developed in partnership with France Infra Rouge, is one of the few to have been approved by the DGAC (General Directorate of Civil Aviation). Our advance in this area has pushed us to develop ever more efficient and reliable solutions, and our partnerships are moving in this direction.

How are data analysis and recovery carried out?

Drone thermography shooting follows very specific rules. It is essential to respect them to maximise the recorded information and minimise artefacts, thermal reflections and other alterations that could compromise a rigorous analysis.

Prise de vue par drone pour un relevé thermographique

Once the thermograms have been calibrated (emissivity, atmospheric temperature, temperature range, etc.), we suggest writing a report offering different degrees of analysis: from simple interpretation of the thermograms to writing a heat balance of your installation by our expert partner in thermography. Finally, we are able to offer you a series of recommendations to reduce your energy bill.

What is the inspection of photovoltaic parks?

In parallel with these services, we have developed a methodology for inspecting photovoltaic power plants on the ground and on roofs. Our onboard thermal measurement solution allows us to quickly identify bypass cells, damaged connections, defective panels or rows of panels thanks to their particular thermal signature. Prise de vue par drone d'un parc photovoltaïqueOur solution is innovative, reliable and very competitive. It is now used regularly by manufacturers in the sector.

As part of a diagnosis of the operating condition of your solar park, we provide an exhaustive list of identified hot spots associated with a geolocalisation of defective panels. Incorporation d'un thermogramme sur une photo RVB d'un parc de panneaux solairesWe also offer an initial diagnosis of the sources of malfunctions: identification of shadng, bypass cells or faulty connection boxes. Our aerial thermography inspections by drone carried out on photovoltaic power plants allow to detect the majority of malfunctions.

What is heat network thermography ?

StudioFly Technologies specialises in the inspection of heat networks by drone. Our technologies and our skills allow us to obtain net results from the evolution of heat networks, whatever their size. The thermal anomalies detected are clearly visible on the thermal image and, unlike other methods, the examination of the installed networks is possible without intrusion and during their normal operation. Using a FLIR XT2 thermal camera allows us to obtain extremely detailed images :
  • Thermal sensitivity less than 34 mk
  • Temperature range from -40 °C to +650 °C
  • Embedded GPS allowing the georeferencing of infrared images
  • Simultaneous thermal / RGB shots.
