Efficient health check for your PV system

PV systems lose money every day – mostly unnoticed.

Yield losses, hotspots, and gradual degradation often remain invisible for years because traditional monitoring only sees average values ​​and inverters are blind to many faults. This costs yield, compromises safety, and renders warranty and insurance claims worthless.


Profit losses happen quietly – dronalise listens.


From flight to report: dronalise is the first highly automated drone thermography system with AI, providing an efficient health check for every PV system. Our technology combines state-of-the-art thermal inspection with AI-supported photogrammetry – for precise, reproducible, and exceptionally efficient inspections.

About the technology

Automated drone inspections for PV systems

We are developing AI-based segmentation models for the detection of PV modules and module areas.
In conjunction with a specially developed photogrammetry method, the drone can autonomously survey the system, fly it optimally, and comprehensively analyze the data.

During the flight, a complete 3D model of the system and a detailed thermographic report are created – automatically, quickly, and reproducibly at any time.
This enables particularly efficient and cost-effective condition analysis as well as reliable comparability during recurring inspections.

INTELLIGENTE FLIGHT PATH GENERATION (coming soon)

To eliminate manual planning errors or gaps in the flight plan from the outset, we are currently working on automated, AI-supported flight path optimization. This ensures a perfectly coordinated flight over every facility.

FAQ

1

Why is thermography useful?

Photovoltaic systems are generally very low-maintenance and often run smoothly for many years. Nevertheless, there can be various reasons why a system might not operate optimally and produce less electricity than expected.


Thermography – an inspection using infrared thermal imaging – allows for the reliable detection of faults in modules or electrical wiring.
The unique aspect of this method is that each fault exhibits a characteristic pattern in the thermal image. This often enables the identification of the cause and potential solutions during the inspection itself.

What types of defects can be detected using thermography?

Faults in PV modules, in the system wiring, or external influences such as soiling or shading lead to uneven current flows. These manifest as noticeable temperature differences in the thermal image.

Typical causes for underperformance include, for example:

  • Cell or contact breaks within a PV module

  • Poor or corroded electrical connections on modules or junction boxes

  • Detachments or discoloration of the lamination that protects the cells

  • Chemical degradation due to moisture, stray currents or UV exposure

  • Faulty or improper wiring of module series

Thermography not only enables the detection of defects but also a quantitative assessment of their severity. Furthermore, potential safety risks,  such as an increased fire hazard,can be identified early on.

When should thermography be performed?

Thermography is particularly useful in the following situations:

  • If you have the impression that your PV system is producing less electricity than expected

  • To check that the correct function is being used, e.g. after commissioning a new system.

  • For older systems, to decide on continued operation, repair or replacement.

  • To clarify whether a possible warranty claim exists.

Regular inspections help to detect performance losses early and to secure the long-term yield of your PV system.
