Technical service solutions for photovoltaik systems

We offers a wide range of technical services based on years of expertise. These services can be tailored to your needs, whether for periodic electrical inspections or expert assessments.

• Visual inspection
• Fault analysis
• Electrical Measurements and Testing
• Electroluminescence Testing
• Expert Reports

Routine visual inspections are one of the most important procedures for PV systems. Well-documented visual inspections not only facilitate later fault analysis but also play a crucial role in asserting warranty or insurance claims.

Through regular inspections, common fault patterns can be identified early, preventing potential damage. As part of the inspection, we systematically assess all components of the system (mounting structures, modules, connectors, cabling, fuses, etc.) and their interconnections.

Additionally, we verify whether all protective functions are properly installed and maintained. In cases of poor installation or incomplete documentation, we provide professional support.

RWA Solar Solutions provides comprehensive services for testing and diagnosing faults in solar systems.

Early detection of faults and defects is critical:

• It reduces costs through preventive measures.
• It prevents significant damage (see Predictive Maintenance).

Examples of common issues include loose module clamps or scorched connectors. Regular maintenance can effectively prevent or detect such faults at an early stage.

We perform electrical measurements and testing tailored to your specific requirements. Our range of services includes:

• Grounding measurements
• Thermography of distribution systems
• DC curve tracing
• Electroluminescence testing
• Data communication tests

For every issue, we select the most efficient and effective testing method to achieve optimal results.

In addition to thermography, drone-based electroluminescence testing offers an innovative alternative. In this process, the PV modules are made to “glow” using a high-voltage power supply. The emitted light is made visible using a drone or camera.

Applications include:

• Detecting microscopic damage or defects in solar modules
• Localization and evaluation of module stringing

Electroluminescence testing acts as a “X-ray scan” for your PV system, enabling precise fault diagnosis.

Depending on your requirements (e.g., evidence, documentation, or legal matters), we provide custom expert reports tailored to your needs.
