We test our modules in harsh conditions
We don’t just claim our modules are strong, we prove it.
At James Cook University’s renowned Cyclone Testing Station in QLD, we subjected our Q.PRO modules to two types of tests to determine their strength: a static and a dynamic test. The first applies increasing pressure onto the back of a module until it breaks, while the second simulates the effects of dynamic loads by alternately pushing and releasing pressure onto the back of a module with increasing pressure.
Q CELLS has cyclone tested all four generations of its Q.PRO range. And each generation has performed better than the last.
Our test highlights that IEC testing according to 61215, which applies only 3 compressions to the rear of the panel, only provides limited information about module strength. Yet, at Q CELLS we do not leave anything to chance and therefore decided to test the actual strength of our modules, with more than 10,000 compressions; each greater in force than IEC tests.
Results for Dynamic Test CAT C
Our modules were tested with increasing pressure to a maximum of 7kPa and subjected to a total of 10360 cycles to simulate a cyclone as best as possible. Accordingly, our modules survived pressure that is equivalent to a 1 in 500 year cyclone in wind region C.
The Safety Factor: The y-axis shows two values - the test pressure (i.e. 7.00kPa) and the equivalent pressure considering the safety factor of 1.238 (i.e. 5.65kPa). You can think of the safety factor as a precautionary measurement to ensure that any unforeseen high risk/low probability events are still accounted for without affecting the safety of the installation.
Results for Static Test
|Static Test load||2400Pa||5400Pa||11,320Pa|
|Test procedure||according to IEC 61215||according to IEC 61215||According to Cyclone Testing Station JCU Townsville|
|Real ultimate strength limit according to Australia standards based on safety factor||Unknown *1)||Unknown *1)||6,970Pa|
Most reputable module manufacturers claim that their modules can withstand 2400Pa based on IEC standards. However, IEC fails to take the safety factor into account – unlike the test we did at James Cook University. Based on those results, you can be confident that Q CELLS modules are strong enough for any wind region in Australia.
*1) The IEC 61215 test only verifies that the modules still produce the required electricity after being subjected to above mentioned mechanical loads, but does not consider any safety factors.

The independent Desert Knowledge Australia Solar Centre (DKASC) is a demonstration facility for commercialised solar technologies operating in the arid solar conditions of Alice Springs in central Australia.
The data of various photovoltaic systems and technologies compiled at the DKASC is available to the public via www.dkasolarcentre.com.au The system performance presented here is a result of an analysis of this data carried out by Hanwha Q CELLS and can be validated by accessing the DKASC data.
Test facility description
A prototype of Q CELLS Q.PRO modules and 4 other Q CELLS technologies are operating alongside a growing number of modules from leading manufacturers at the Alice Springs test site. The Q.PRO modules feature highest quality, outstanding performance and positive power sorting.
All systems in this analysis are connected to inverters with comparable performance characteristics.
The data collected by DKASC uses a singular monitoring system for all installations and data used was taken between March 1, 2010 and August 31, 2013. For this analysis, if data points of any one system were missing for a certain period of time, data for all systems was not considered during that period to maintain a level playing field.
The data reveals that Q CELLS Q.PRO modules are top-performers in terms of generating electricity compared to modules in equivalent system configurations from other manufacturers.
