Q.PEAK DUO-G8 Maximum performance and outstanding efficiency

Q.PEAK DUO-G 345-360

The Q.PEAK DUO-G8 is our monocrystalline solar module with power classes of up to 360 Wp and an efficiency of up to 20.4 %. Thanks to the latest generation of unrivalled cell concept Q.ANTUM DUO, the Q.PEAK DUO-G8 solar module provide uniquely high yields on a small surface area. To this end, half-cells are combined with state-of-the-art circuitry and 12-busbar design. The black half-cells of the Q.PEAK DUO-G8 lend even the most exclusive building an aesthetic elegance.

The Q CELLS Anti LID Technology prevents light-induced degradation (LID), which can reduce system performance drastically – or almost totally. Other conventional monocrystalline solar cells lose much of their in-itial power through insolation. The Q.PEAK DUO-G8 prevents this with Anti LID Technology.
