QC Key Points

Step-01

High Quality Starts from the Very Beginning

Seraphim performs thorough assessments of all incoming raw materials. There are overall 156 quality control tests including cell efficiency and pull strength detections, EL tests, EVA gel content tests, resistance tests of J-box cable, and frame stability tests. All these tests guarantee that every batch of raw materials and every single component is up to Seraphim's standard of quality.

Step-02

3 Times EL Tests in Production

Each Seraphim module has to pass 3 rounds of the EL test: pre-lamination, post-lamination, and before packing. These tests minimize defective products while reducing the overall production costs.

Step-03

High-precision Performance Tester

All production lines in the Seraphim manufacturing plants are equipped with HALM photovoltaic product characterization testers. The German-made H.A.L.M. performance tester uses state of the art Triple A+ level light source with a complex power regulation system and freely adjustable optical pulse settings. H.A.L.M. enables Seraphim to accurately and easily scan out the most important data of each module on the line, such as maximum power, temperature coefficient, and low-irradiance performance in a relatively short time.

Step-04

Innovations in QC, Improved Reliability

Seraphim innovates the QC process by installing modulator tubes behind the visual inspection checking machine. This fill-in light magnifies flaws like broken cells, micro-cracks, ribbon-less edge chips, etc. so that no defective module will be shipped to our clients. In the meantime, we use high-resolution monitors to check whether the gaps between cells meet requirements. This series of quality control tests guarantees that modules function to all the technical specifications while maintaining visual uniformity.

Step-05

Periodical Tests for Long-term Guarantee

Every quarter, Seraphim spot checks all types of modules being produced in the past three months, including thermal cycling, damp heat, PID, UV, humidity freeze, hot spot, etc., to double-check our product.

Third-party Certification

Quality is Seraphim's core competitiveness. Starting from the initial stages of production, we rigorously control every step and hold ourselves and our products to strict standards. We take pride in the quality and reliable performance of each one of our modules, even in the most extreme conditions.

After an on-site inspection and comprehensive evaluation by the expert group of Det Norske Veritas (DNV.GL), Seraphim successfully passed the three system certifications, including ISO9001: 2015 Quality Management System Certification, ISO14001: 2015 Environmental Management System Certification, and ISO45001: 2018 Occupational Health and Safety Management System Certification.

In addition, Seraphim also applied the "GB/T 19580-2012 Criteria for Performance Excellence". It is not only applicable to the selection of the National Quality Awards, but also puts forward requirements for enterprise organizers, customers, employees, suppliers, partners, etc., to guide enterprises to self-learning, pursue outstanding performance, improve product, service and operation quality, and enhance competitive advantage.
