Drone thermography is a non-destructive analysis technique based on the acquisition of infrared aerial images. This occurs thanks to the radiation emitted by the system, which is able to determine the temperature.
Thermography can be applied in all sectors where an aerial thermographic technical inspection is required. In fact, thanks to drone technology, it is possible to perform a complete mapping of the area, inspecting the object or surface quickly and easily.
At SG drones we have the possibility, thanks to our thermography drones, to perform area inspections with high performance sensors and FLIR, DJI XT2 and DJI H20T thermal cameras.
The census of photovoltaic panels performed with drones is an important part of the technical inspection of solar systems. It consists of an exhaustive and systematic collection of information on the photovoltaic panels installed in a specific photovoltaic plant or location. The main objective of the census is to obtain a complete and detailed view of all the solar panels present in the system, which allows to have an updated record of the configuration and distribution of the solar modules.
During the survey, the drone moves along the entire PV plant and captures high-resolution images of each panel. These images can be both visual and thermographic (infrared) to obtain a greater amount of data on the condition of the panels. In addition, the drones can carry out other specific measurements and tests to evaluate the performance and efficiency of the panels.
The mapping of defective hot spots is an essential part of the technical inspection of photovoltaic panels with the use of a drone. It consists of using the thermographic images obtained during the technical inspection with drones to identify and precisely locate the hot spots (“HOT SPOT”) present on the solar panels.
During the technical inspection, thermographic cameras mounted on the drone capture infrared images of the photovoltaic panels in operation. Hot spots are generated when faulty, poorly connected or malfunctioning cells cause excessive heat buildup in those areas.
The mapping of defective hot spots involves the following steps:
Mapping faulty hot spots is essential to ensure optimal operation and performance of photovoltaic panels. By identifying and addressing problems early, energy losses are avoided and system life is extended, resulting in a higher return on investment for solar installation owners.
Photovoltaic panel monitoring with drones is a continuous and systematic practice that involves regular tracking of the performance and status of solar panels installed at a specific PV plant or location using drones and telemetry technologies. It consists of the periodic collection of relevant data and measurements to evaluate the efficiency and performance of the PV panels over time.
PV panel monitoring with the use of a drone can include the following activities:
Drone monitoring of photovoltaic panels is a powerful tool to ensure optimal performance and long-term efficiency of solar systems. It enables proactive and efficient management of the PV plant, as well as informed decision making to maximize solar energy production and extend the lifetime of the panels.
Performance and post-production analysis is a critical phase in the technical inspection of photovoltaic panels with drones. After visual and thermographic inspections and other field measurements, the collected data is processed and analyzed to obtain detailed and valuable information on the performance and condition of the solar panels.
The performance analysis and post-production process includes the following stages:
Performance and post-production analysis is essential to obtain a detailed and accurate picture of the status of the PV panels and overall system performance. This provides valuable information to make informed decisions on system maintenance, optimization and improvement, helping to maximize solar energy production and extend the life of the panels.
In general, drone thermography is an effective technique for the technical inspection of photovoltaic panels. By using this technique, owners of solar installations can ensure that their systems are working properly and that they are generating the expected energy.
