Solar cells in continuous operation
Modern PV and solar cells are meant for long operating times: They are expected to convert solar energy into electricity for around 20 years or more. To prevent individual solar modules from breaking prematurely, regular maintenance is essential. Therefore, every large solar plant should be checked for damage at least once a year.
Possible damage can have various effects: Defective cells or substrings can lead to a significant reduction in the efficiency of individual modules. Prolonged weathering and UV radiation cause corrosion of electrical components over time, increasing safety and fire risks. This poses a major task for the system operator.
Thermal images with UAVs
How can defects be localised as early and cost-effectively as possible? Recently, flying drones have proven to be a valuable testing instrument. They allow easy and efficient inspection by taking infrared images from above. The temperature differences measured reveal where possible damage or inefficient yield performance exists.
Damage to solar modules
Possible reasons for damages to solar modules:
- cracks in the module
- penetration of humidity
- faulty cabling
- aging or continuous exposure
In order to find defects and damage to solar modules, we only use the best equipment: our outdoor UAVs are equipped with powerful electric motors which ensure sufficient stability – even in strong winds. High-resolution infrared cameras are used for thermal recordings. This means that no detail remains unseen.
