Tested at the James Cook University’s Cyclone Testing Station (CTS) in Townsville, Australia, Hanwha Q CELLS ‘Q.PRO-G3’ modules have passed tests that include withstanding wind speeds of up to 240 km/h.
The Q.PRO-G3’ modules differ from conventional modules by employing a thinner (35mm) frame design features a high-tech aluminium alloy that allows for wind loads of up to 5,400 Pa while reducing module weight to 19 kg.
“Passing the Cyclone Test at James Cook University’s renowned Cyclone Testing Station showcases the superior quality of our solar modules, engineered in Germany”, said Andreas von Zitzewitz, COO of Hanwha Q CELLS. “Withstanding a 1 in 500 year cyclone in Australia’s most severe wind region is something only very few PV modules are capable of.”
According to the company, the CTS undertook two types of testing to ascertain module strength, a static and a dynamic test.
In the first test, pressure was increasingly being applied onto the backside of the modules’ back until it collapsed. The second test simulated the effects of dynamic loads by alternately pushing and releasing pressure onto the back of the module, all the while increasing the pressure.
During the test, a maximum pressure of 7kPa was applied in a total of 10,360 cycles to simulate a cyclone as best as possible.
The company noted that under such conditions the modules would have withstood cyclone Larry (2006) with wind speeds of up to 215 km/h. The modules were also deemed to have been strong enough to survive a 1 in 500 year cyclone in wind region C, the most severe region for Australian cities.
