The new Q.PRO-G3 is the reliable evergreen for all applications. The third module generation from Q CELLS has been optimized across the board: improved output yield, higher operating reliability and durability, quicker installation and more intelligent design.
INNOVATIVE ALL-WEATHER TECHNOLOGY
Maximum yields with excellent lowlight and temperature behaviour.
ENDURING HIGH PERFORMANCE
Long-term Yield Security due to Anti PID Technology1, Hot-Spot Protect, and Trace able Quality Tra.Q™.
Long-term stability due to VDE Quality Tested – the strictest test program.
SAFE ELECTRONICS
Protection against short circuits and thermally induced power losses due to breath able junction box and welded cables.
Increased flexibility due to MC4-intermateable connectors.
PROFIT-INCREASING GLASS TECHNOLOGY
Reduction of light reflection by 50%, plus long-term corrosion resistance due to high-quality »Sol-Gel roller coating« processing.
LIGHTWEIGHT QUALITY FRAME
Stability at wind loads of up to 5400 Pa with a module weight of just 19 kg due to slim frame design with high-tech alloy.
MAXIMUM COST REDUCTIONS
Up to 31% lower logistics costs due to higher module capacity per box.
EXTENDED WARRANTIES
Investment security due to 12-year product warranty and 25-year linear performance warranty2.
THE IDEAL SOLUTION FOR:
Rooftop arrays on commercial/industrial buildings
Ground-mounted solar power plants
Rooftop arrays on residential buildings
APT test conditions: Cells at -1000 V against grounded, with conductive metal foil covered module surface, 25°C, 168h
