Q.Maxx 320-335

The new Q.MAXX solar module from Q CELLS impresses thanks to innovative Q.ANTUM DUO Technology, which enables particularly high performance on a small surface. Q.ANTUM’s world-record-holding cell concept has now been combined with state-of-the-art circuitry half cells and a six-busbar design, thus achieving outstanding performance under real conditions — both with low-intensity solar radiation as well as on hot, clear summer days.

Q.antum

MORE LIGHT. MORE PERFORMANCE. MORE ELECTRICITY. – Q.ANTUM
Q.ANTUM Technology supercharges ordinary solar cells and modules. Q.ANTUM delivers exceptional performance under real-world conditions. We designed Q.ANTUM to generate more power when the sun is rising, setting, or even behind clouds. You’ll also see higher yields in the middle of hot and sunny summers, and during clear fall and winter days, when the sun is not as high in the sky. We enhanced low-light performance, but also the output of our modules across a range of temperatures – all to bring you higher profits.
