Seraphim Energy has announced that its 210mm modules have passed TÜV SÜD’s high-grade hailstone impact test, with a performance degradation rate as low as 0.2 percent.
Hailstones used in standard impact testing are only 25 millimeters in diameter and strike the modules at a speed of only 23 meters per second. However, for testing of the Seraphim modules, the parameters were upgraded to incorporate hailstones of 45 millimeters in diameter striking the glass surface of the modules at a speed of 30.7 meters per second (about 110.5 kilometers per hour). The results indicated the anti-kinetic energy impact performance of the modules to be ten times the industry standard.
Thorough testing included strikes to 11 defined impact points on the collector surface, after which the appearance, safety and power output of the modules was shown to be only slightly affected, with performance degradation as low as 0.2 percent.
“Passing the hailstone impact test proves that Seraphim’s PV products are highly reliable, a direct result of our dedication in improving product performance, introducing innovation and conducting strict quality control,” commented Polaris Li, Seraphim’s President.
