Mr. Wang, the certification director of a multinational photovoltaic enterprise, once struggled with the certification of huge components: "Our 3m×5m ultra-large photovoltaic modules required 15 segments of testing using traditional small light spot simulators, which took 3 days and resulted in a 8% error in assembly. When submitted for certification by TÜV Rheinland, the product was rejected directly. The plan to enter the European market was postponed by 6 months. What was even more challenging was that some overseas markets required xenon lamp equipment for testing, but traditional xenon lamps had a small surface area and poor stability, and simply couldn't meet the requirements."
The implementation of the 3A level xenon lamp steady-state solar simulator by Saifan Photovoltaic completely solved the certification problem. The equipment is equipped with an imported 1500W ultra-high pressure short arc xenon lamp array, achieving full coverage of a 3m×5m ultra-large area, without the need for segment testing, reducing the single-module testing time from 72 hours to 14 hours, increasing efficiency by 5 times, and reducing certification costs by 65%. The core performance meets the 3A full indicator standards: spectral matching degree A+ level (0.875-1.125), light intensity uniformity ≤ ±3%, time stability ≤ ±0.2%/h. The data is 100% recognized by international institutions such as TÜV and UL, and perfectly adapts to the certification needs of different regions around the world.
"After introducing the Sevan equipment, our large-scale components passed the certification test successfully and smoothly opened the doors to the European and Australian markets." Mr. Wang calculated, "Previously, the annual electricity cost for 10 small spotlights was 400,000 yuan, and the downtime loss due to equipment replacement was 1.2 million yuan; now, with one Sevan equipment, electricity consumption is reduced by 60%, and the annual electricity savings are 240,000 yuan. The xenon lamps support rapid replacement in 15 minutes and have a lifespan of 1,000 hours. In just over a year, the output value has exceeded 30 million yuan." In response to the mass production demand, the Sevan LED steady-state model has more advantages. The light source has a lifespan of up to 100,000 hours, and the annual energy consumption of the 1GW production line has decreased from 1.2 million kilowatt-hours to 400,000 kilowatt-hours, achieving a 66.7% energy saving and significantly reducing the long-term usage costs.
