Drone thermography
We specialise in thermographic inspections for photovoltaic installations, power lines and wind turbine maintenance.
Thermography is the technique that helps us determine the temperature of an object from a distance without needing to interact with it. This facilitates the mapping of installations and the detection of faults and defects in the system and networks for proper maintenance. It is therefore a proactive discipline that directly impacts cost savings, detecting and locating faults before problems escalate.
Methodology
We capture infrared radiation from the electromagnetic spectrum, converting radiated energy into precise temperature information. To achieve this, we use thermovision thermal cameras: advanced technological devices that capture the exact temperature of objects and spaces through a caloric system, recording infrared radiation continuously.

Uses of thermographic analyses
Thermographic analyses are used to obtain the surface temperature distribution of the object under review. In this way, a heat map is generated that reveals hot or cold spots, accurately identifying any anomaly in materials, objects or industrial installations.
Why is a thermographic analysis useful?
Thermographic analyses have a wide range of applications in very diverse sectors, being especially useful for technical building inspections, as well as for thermographic studies of photovoltaic installations, power lines and wind turbines.
What is infrared thermography?
A large portion of failures in electrical, mechanical or electronic equipment manifest as a significant increase in temperature before breaking down completely. Infrared thermography allows these heat patterns to be detected in the infrared wavelength spectrum —invisible to the human eye—, revealing component deterioration before a critical failure occurs.
Infrared thermography detects the thermal energy emitted by an object, converts it into visible temperature values and displays the result through a radiometric image. Strictly speaking, infrared thermography consists of capturing the "temperature of the image" (thermography) "below the colour red" (infrared).
By using a thermographic camera, it is possible to obtain these thermal images without the need for direct contact with the equipment. Infrared cameras capture radiometric images that contain apparent temperature measurements for each pixel of the image.
Thanks to this technology, any anomalous thermal increase can be identified to analyse the condition of each element independently and accurately.
Likewise, thermographic cameras are key tools for solving and preventing problems related to energy losses or moisture leaks in the structure of any building.
Photovoltaic Installation Maintenance through Thermography
To ensure proper maintenance of photovoltaic installations, it is essential to carry out thermographic analyses on a regular basis. These inspections help prevent performance losses in the solar plant and act as a crucial fire protection measure.
Performing a thermal analysis on a photovoltaic plant takes little time and is carried out without the need for direct contact with the solar panels. Thermal anomalies and temperature differences become immediately visible, allowing problems to be resolved quickly before they affect production.
The main faults in solar panels are identified through the detection of hot spots. These deficiencies are diagnosed with infrared cameras that measure changes in thermal properties, which are usually due to:
- Defective bypass diodes.
- Short circuits in solar cells.
- Accumulation of moisture, dust or dirt (soiling).
- Breakage or cracking in module glass.
- Power loss due to faulty connections or wiring in poor condition.
- Degradation and natural deterioration over time.
Wind Turbine Inspection and Thermography
By using drones equipped with advanced thermal cameras, we carry out thermography on wind turbines accurately and continuously, facilitating the early detection of anomalies in wind energy infrastructures.
Wind turbines are the cornerstone of wind energy, being responsible for efficiently transforming the force of the wind into usable electricity.
The thermographic and multispectral cameras we use provide critical data that is invisible to the human eye. Thanks to these cutting-edge techniques, we perform comprehensive inspections to detect potential cracks or structural damage in the tower and blades, insulation loss in the nacelle, as well as anomalous friction in moving and rotating parts. Likewise, we assess the overall performance of the energy plant, covering from transformer stations to high-voltage power lines and electrical transmission.
Thermography in Power Stations and High-Voltage Lines
By determining the surface temperature of components without the need for physical contact, thermography is consolidated as an indispensable tool for the early detection of anomalies in power stations and high-voltage lines.
A key advantage of this system is that measurements and technical audits are carried out with the power station in full operation. This not only facilitates the exact location of faults under real load, but also allows them to be resolved in a short time without interrupting the supply.
To ensure operational safety, these inspections must be scheduled on a continuous and preventive basis, as mechanical or electrical failures can occur at any time.
One of the most common problems in electrical networks is component overheating, caused by an anomalous increase in electrical resistance.
This resistance usually originates from damaged, faulty or worn connections over time. When resistance increases, a loss of energy in the form of heat occurs, dramatically raising the risk of fires in high-voltage installations if not corrected in time.
At Ofiteat we put at your disposal specialised infrared thermography services. We have qualified engineers and cutting-edge technological equipment to audit your infrastructures with full reliability. Do not hesitate to contact us for personalised advice.
Photovoltaic plant operation & maintenance (O&M)
"Prevention is better than cure" goes the saying, and how right it is when talking about the productivity of a photovoltaic plant.
Embarking on energy production through a photovoltaic installation entails a high cost for any business owner, so hiring a maintenance service is essential to obtain the highest possible yield from the plant. It is a proactive discipline that directly impacts cost savings, detecting and locating faults before problems escalate.
Drone Thermographic Inspection in Photovoltaic Plants
The most common breakdowns in a photovoltaic plant are caused by faults in cell connections, busbar interconnections or defects in bypass diodes. Preventing and detecting these anomalies in time is essential to optimise operational costs, since a preventive audit minimises the economic impact of unforeseen stoppages.
At Ofiteat we develop advanced predictive maintenance methodologies for solar plants. Our goal is to ensure that installations operate continuously at their maximum performance, guaranteeing significant time and cost savings for our clients.
The integration of lighter and more efficient thermographic cameras has revolutionised the industrial sector, offering highly competitive inspection solutions. Their application in the prevention and diagnosis of faults within photovoltaic installations represents a strategic technological advance.
Leadership and Aerial Technology
At Ofiteat we have state-of-the-art thermal cameras with a resolution capable of capturing details of up to 3 cm per pixel. We have enhanced this reach by integrating these cutting-edge devices into unmanned aerial vehicles (drones).
We stand out as a benchmark engineering company in the use of drones for topographic surveys, site inspections and power line monitoring. We hold all the certifications required by aeronautical authorities and strictly comply with current national and international regulations.
Aerial data capture stands out for its speed and precision. Through drone operations we can cover up to 22 hectares per working day, optimising resources compared to the average three days that an operator equipped with a handheld camera would require in the field.
Planning and Technical Criteria
Since each solar infrastructure has unique characteristics, we design customised flight plans for each photovoltaic project. The planning is meticulously adjusted according to the geographical location, plant geometry, weather variables and the ideal solar irradiance angle depending on the season.
To ensure accurate data capture, technical specifications require photovoltaic modules to record a minimum irradiance of 600 W/m², with a recommended threshold above 700 W/m². For this reason, flights are scheduled in specific time windows that guarantee high solar radiation. We also monitor atmospheric variables, limiting operations to wind speeds below 30 km/h.
Days with variable cloud cover are avoided, as clouds generate diffuse reflections on the module glass that could distort the accuracy of thermographic analyses.
During real-time monitoring, our technicians assess potential serious anomalies in order to perform more detailed passes over identified critical areas, optimising the performance of the aerial operation.
Advanced Analysis and Technical Reports
After the field phase, the thermal data is processed by Ofiteat's expert engineers. We use specialised industry tools and software (such as Pix4D, FLIR Tools, Testo IRSoft or Grayess), as well as proprietary algorithms. This allows us to consolidate reliable diagnoses and accurate heat maps in a matter of hours.
Finally, we generate detailed technical reports that geolocate and accurately identify critical faults such as cell breakage, hot spots or faulty connections.
By delegating technical inspection to Ofiteat, you will have the backing of a qualified team, anticipating serious breakdowns and avoiding costly corrective repairs.
