Q.PEAK DUO BLK-G8⁺ Maximum performance and outstanding efficiency

Q.PEAK DUO BLK-G8⁺ 335-350

Our Q.PEAK DUO BLK solar modules have been developed for use on truly exclusive buildings. To this end, we utilise black half-cells and black anodised aluminium frames in conjunction with black rear foil. Ultra-thin connecting wires on the solar cells allow the solar modules to look like a uniformly black area. Our monocrystalline solar modules of the Q.PEAK DUO BLK family are also distinguished by outstanding yields thanks to power classes of up to 350 Wp and efficiencies of up to 19.8 %. A new generation of the unrivalled Q.ANTUM DUO cell concept, which is now combined with state-of-the-art circuitry and 6-busbar cell design, makes these tremendous values possible.

The Q CELLS Anti LID Technology prevents light-induced deg-radation (LID), which can reduce system performance drastically – or almost totally. Conventional solar cells lose much of their initial power through normal insolation.
