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 test 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.
02. 3 Times EL Tests in Production
Each Seraphim module has to pass 3 rounds of EL test:pre-lamination, post-lamination, and before packing. These tests minimize defective products while reducing the overall production costs.
03. HALM Inside for Performance Testing
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 the low-irradiance performance in a relatively short time.
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.
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, and etc., to double check our product.
