Major tier-one PV manufacturer JA Solar said all of its PV module series had passed the ‘high-grade’ hailstone impact test conducted by TUV Rheinland.
The company said that the TUV Rheinland demonstrated its modules could be deployed in harsh environments, opening further markets for the fasted growing PV manufacturer in 2014.
Jian Xie, president of JA Solar said: “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.”
According to JA Solar, the high-grade hailstone impact test, results in hailstones with a diameter of 45mm striking the glass surface of the modules at a speed of 30.7 metres per second (about 110.5 km per hour), compared to hailstones used in the standard hailstone impact test strike are only 25mm in diameter and strike modules at a speed of only 23 metres per second.
The anti-kinetic energy impact performance of JA modules is ten times the original industry standard.
