Endeas All-in-One takes module testing further
Optimizing the total cost of ownership is one of the most essential keys to improved production efficiency in PV module manufacturing. The All-in-One concept developed…
The QuickSun 650 is a fully automated and highly productive PV module testing station. Thanks to the ability to handle up to 150 modules per hour, QuickSun 650 is an ideal solution for mass production of solar panels.
QuickSun® 650 is compatible with Endeas All-in-One concept. This means I-V test, EL imaging, optical inspection, bypass diode test, and electrical safety tests are integrated into single machine. Less machines needed translates into saved floor space and higher production uptime.
As the All-in-One concept reduces the need for floor space, it opens up new possibilities for line upgrades. In addition, shorter production line can be ramped up faster, including the training of operators and engineers.
QuickSun® 650 has outstanding measurement stability with Pmax repeatability smaller than 0.1 %. Combining superior productivity with durability and low maintenance costs, QuickSun® 650 is able to provide an exceptionally low cost of ownership as a complete tool for PV module testing.
QuickSun 650 achieves A+A+A+ classification. Irradiance non-uniformity of < 1% is maintained over the test area. The spectrum produced by the Xenon flash extends from 300 to 1200 nm, fully compatible with the new standard IEC 60904-9 Ed.3. The spectral coverage of the spectrum is 100% making sure variation in PV module materials does not go unnoticed.
Long-term instability (LTI) is < 0.5 % during the 60 ms long flash pulse. Even the high efficiency modules are measured accurately with Capacitance Compensation (CAC) method. The PV module testing station is designed to enable the single-side testing of bifacial modules at elevated intensities. The applied tests and reports comply fully with the standards IEC 60904-1 and IEC 60904-9.
EL images with 200-μm pixel resolution are recorded with six 20MP cameras. The high resolution images enable software-based automatic image analysis to identify and categorize small faults, such as micro-cracks and finger interruptions. Bypass diodes are tested according to the functionality test specified in the standard IEC 61215-2. A high-resolution image of the cell side of the module is recorded and used to analyse such features as cell-to-cell distance, particle contamination, and ribbon misalignment.
QuickSun 650 has the capability to perform hipot and ground continuity testing. The actual leakage current is measured with a sensitive enough instrument that enables a run-time diagnosis of both contacting reliability and real module leakage characteristics. A 100% coverage of electrical safety testing for UL certification is achieved.
