At SDC, we take pride in engineering innovative, custom solutions for solar module testing. As the solar industry continues to evolve, manufacturers require reliable, high-precision testing equipment to ensure the quality, efficiency, and longevity of photovoltaic (PV) modules.
With years of experience in automation, our team has developed a wide range of advanced testing and inspection systems designed specifically for PV module manufacturers. Our automated solutions provide accurate, repeatable results while optimizing throughput and minimizing manual handling.
Our automated solar testing equipment is designed for precision, efficiency, and long-term reliability. We work closely with manufacturers to develop systems that enhance quality control, reduce waste, and improve overall production efficiency.
Automating solar panel testing with the latest technology and intelligent programming ensures every module meets the highest standards for quality, efficiency, and energy output. Here are six key advantages of implementing advanced automation in solar testing:
Advanced automation ensures consistent and highly precise testing, eliminating human error and providing accurate performance data for every solar panel.
Automated systems significantly speed up the testing process, allowing manufacturers to inspect more panels in less time while maintaining quality standards.
Cutting-edge technology such as electroluminescence (EL) and flash testing identifies microcracks, electrical faults, and performance issues before modules reach the market, reducing warranty claims and improving reliability.
By rigorously testing each panel’s power output and efficiency, automation ensures only high-performing modules reach the field, maximizing energy production for end users.
Automated systems collect, store, and analyze test results, providing manufacturers with real-time insights, traceability, and data-driven quality control improvements.
State-of-the-art automation ensures every module meets strict industry certifications (IEC 61215, IEC 61730, UL 1703), guaranteeing safety, durability, and long-term performance.
The wet leakage current test is a critical evaluation used in the solar industry to assess the electrical insulation of photovoltaic (PV) modules under wet operating conditions. This test ensures that moisture—whether from rain, fog, dew, snow, or condensation—does not penetrate the active electrical components of a solar module, which could lead to corrosion, ground faults, or potential safety hazards.
This test is crucial for verifying the durability and safety of solar panels in outdoor environments where exposure to moisture is inevitable. Inadequate insulation can lead to electrical leakage, performance degradation, and increased safety risks such as electric shock or system failure. Ensuring compliance with this test helps manufacturers prevent long-term reliability issues and costly field failures.
The wet leakage current test is a mandatory component of IEC 61215 certification, a key industry standard for PV module safety and performance. It is performed after the initial insulation resistance test and repeated at the end of the quality control sequence to verify that all modules meet the necessary safety and reliability benchmarks before deployment.
By implementing rigorous wet leakage current testing, manufacturers can ensure that their solar panels are built to withstand real-world environmental conditions, providing safe and efficient energy generation for years to come.

Durability and Reliability Testing for PV Modules
SDC’s mechanical load test systems provide a comprehensive approach to evaluating the strength and longevity of photovoltaic (PV) modules. These systems simulate the mechanical stresses that solar panels endure in real-world environments, such as wind, snow, and handling during installation. By integrating both static load testing and dynamic load testing, we ensure the durability and reliability of solar modules under a variety of external forces.
The static load test evaluates a solar module’s resistance to pressure and deformation. Our system applies a predefined weight to the module, simulating the effects of typical wind and snow loads. This test ensures that the module can withstand external pressures without compromising its structural integrity. The test setup includes a zone control feature, which allows for testing specific areas of the module to target potential weak points.
Dynamic load testing is used to assess the resilience of solar modules against dynamic forces, such as those produced by strong winds or typhoons. Our system uses a controlled setup to simulate the push-pull forces that occur during high winds. This test evaluates the module’s ability to endure the extreme conditions of tropical storms and other wind-related natural disasters, helping manufacturers optimize module durability for regions prone to such events.
By conducting static and dynamic mechanical load testing, manufacturers can ensure that their PV modules meet the rigorous demands of the solar market and perform reliably in a variety of environmental conditions.
