JA Solar proudly announced that all of its PV modules have passed the high-grade hailstone impact test conducted by TUV Rheinland.

During the high-grade hailstone impact test, hailstones with a diameter of 45 millimeters strike the glass surface of JA's modules at a speed of 30.7 meters per second (about 110.5 kilometers per hour). In contrast, hailstones used in the standard hailstone impact test strike are only 25 millimeters in diameter and strike modules at a speed of only 23 meters per second. The anti-kinetic energy impact performance of JA modules is ten times the original industry standard.

Mr. Jian Xie, President of JA Solar, commented, "In order for our products to withstand harsher weather conditions, it is a necessity that our modules pass the hailstone impact test under more stringent conditions. Passing the TUV high-grade hailstone impact test is further testament to the high reliability of JA Solar's PV products and our competitive advantage as a leader in industrial PV technology".
