Solar energy: What's new in photovoltaics?


Hanwha Q CELLS will introduce its new G3 solar modules at the Clean Energy Week in July.

The Q.PEAK-G3 and Q.PRO-G3 solar modules offer impressive energy output with advantages including superior low light optimisation, top performance in Australian conditions, hot spot protection, suitability for windy and coastal areas, and longevity of output.

Superior low-light optimisation

The Q CELLS G3 range achieves 97-98% output in low-light conditions due to optimised low-light behaviour, and by using anti-reflection technology to capture the sun’s rays instead of reflecting them. More light is therefore harnessed by the sun during early morning, late afternoon and cloudy periods, and converted to energy.

At an individual cell level, Q CELLS G3 modules reach 19.5% efficiency, which has been confirmed as a world record by The Fraunhofer Research Center for Silicon Photovoltaics in Germany.

Top performance in Australian conditions

Hanwha Q CELLS G3 modules have been tested at the Desert Knowledge Australia Solar Centre, which tests well known panels under the extreme conditions of the Australian outback. The Q CELLS G3 range achieved up to 10.8% higher output than other modules installed at the centre. 

Hot spot protection

During the production process, solar cells can be subject to stresses that can create ‘hot spots’, which means that solar energy is wasted as heat, instead of being turned into electricity. Q CELLS engineers test every module that leaves the factory for hot spots, helping Q CELLS solar modules produce up to 5% more energy over their lifetime.

Wind and coastal suitability

The Q CELLS G3 range is perfect for windy, coastal areas. The module frames are made from aluminium alloy, which is particularly tension resistant due to a special thermal treatment. Tested at the Cyclone Testing Centre at the James Cook University in Queensland, the modules have been proven to be tough enough to have survived cyclones Larry and Yassi.

Q CELLS modules feature corrosion resistant ARC glass and are safe enough to be installed in coastal areas.

Longevity of output

The combination of heat, humidity and high voltage can create Potential-Induced Degradation (PID) in modern PV cells. Q CELLS engineers have optimised cell production processes to eliminate PID at the cell level.

Tests conducted on 13 well-known PV brands in 2012 at the Fraunhofer Center revealed that Hanwha Q CELLS was only one of four brands to achieve a score of 100% energy output after PID resistance tests. Five of the major brands tested achieved scores of below 50%.

The G3 series is backed by an extended 12-year product warranty as well as a linear performance warranty that guarantees at least 83% of nominal power after 25 years.

Hanwha is the major sponsor of this year’s Clean Energy Week being held from July 24 to July 26. Clean Energy Week is organised by the Clean Energy Council.
