Aerial thermography by drone is mainly used for the thermal diagnosis of industrial sites and buildings or in the search for malfunction points on electrical transport and production installations.
420 thermal inspections since 2012
Our teams have thermographed solar panels, heritage, heat networks, heavy industries and many more. These different aerial inspection frameworks have enriched our expertise and provide you with qualified results. We provide you with a precise and synthetic report that accompanies you in your decision-making

years of experience
Teams trained and qualified in aerial thermal analysis by drone.
The different application areas of aerial thermography
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.
Identification of thermal anomalies specific to building pathologies. Collective, individual and industrial. Thermal bridges, degradation or lack of insulation.
Thermal inspection without production stoppage. No human commitment. Aerial thermography on sensitive sites: SEVESO, nuclear, army… Team trained in industrial risks.
Thermal inspection process
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.
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?
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.
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?
Who takes care of the thermal data acquisition?
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.
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. Our 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. We 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 ?
- 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.
France Télévision Interview
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.
