Operational precision to maximise the lifespan of a photovoltaic plant
Solar energy is expanding across the region. New photovoltaic parks are being integrated into the energy matrix, while existing facilities continue increasing their capacity. However, the real challenge lies elsewhere: maintaining the performance of each panel over time. A photovoltaic plant may contain thousands of modules, yet when even one loses efficiency, overall generation gradually declines and hot spots or internal faults may emerge. At this point, inspection stops being a periodic check and becomes a strategic management tool.
Beyond visual inspection
For years, solar panel maintenance relied on manual inspections or partial performance analyses. The challenge is that many faults are not visible to the naked eye. Microcracks, faulty connections, uneven degradation or overheated cells require thermal analysis and data processing to be accurately identified.
At Uali, we operate drones equipped with thermal and optical sensors capable of surveying large areas in significantly less time than traditional methods. Data capture is systematic and repeatable, enabling comparison between inspection campaigns and the detection of subtle variations in module behaviour.
From aerial images to operational decisions
Each inspection generates a massive volume of information. Without an appropriate management tool, this material can quickly become difficult to analyse. For this reason, the service does not end with image capture.
Within Uali’s management platform, data is processed using artificial intelligence models specifically trained for energy assets. The system identifies anomalous thermal patterns, classifies events and organises them according to criticality levels.
This enables teams to:
- Detect hot spots before they impact production.
- Identify panels with irregular performance.
- Locate connection failures or advanced degradation.
- Prioritise interventions based on real generation impact.

Efficiency is not only about producing more. It is about losing less
In photovoltaic plants, small accumulated losses can translate into significant differences in annual production. An unattended faulty module can affect the performance of an entire string, while an ignored thermal anomaly may lead to major damage.
Periodic inspections enable preventive action, reducing downtime and avoiding unnecessary replacements. They also provide clarity for maintenance planning by focusing interventions only where required. Instead of inspecting the entire plant uniformly, technical teams can act precisely where intervention delivers real value.

Scalability across large-scale solar fields
In Argentina, many photovoltaic plants are located in vast territories exposed to variable climatic conditions. Manual inspection logistics in such environments can be complex and costly.
The combination of automated flights, precise mission planning and intelligent analysis enables thousands of panels to be inspected within optimised working periods. This not only reduces operational time but also minimises field exposure for personnel and improves data traceability.
At Uali, we develop solutions that connect monitoring, analysis and action. Solar panel inspection forms part of a broader strategy for intelligent energy asset management. In a context where solar energy continues to expand in Argentina, having precise and actionable information is just as important as solar radiation itself.
