As part of the Q.PEAK DUO-G9 series, three high-density solar modules will be launched, all of which feature Q.ANTUM DUO Z Technology, where gaps between the solar cells are closed to increase solar module efficiency in relative terms by 4%, delivering an overall efficiency of up to 21.1%, Q CELLS said.
The Q.PEAK DUO ML-G9 version has 132 half-cells to deliver a solar module with a solar power output of up to 395Wp. The larger Q.PEAK DUO XL-G9.3 increases the number of solar cells from 144 half-cells in previous iterations to 156 half-cells, delivering a solar power output of up to 465 watts. This XL version is 8.3cm longer, but only 1kg heavier and the same width as previous products.
A third version of the Q.ANTUM DUO Z range has also been developed by to specifically serve the needs of Europe’s residential rooftop solar panel installation markets. The Q.PEAK DUO BLK-G9 features 120 half-cells to deliver up to 345Wp of power and 20.8% overall efficiency. Q CELLS said that with a weight of 17.5 kg, the solar panels “can be more easily installed on rooftops”.
Further innovations featured in the Q.ANTUM DUO Z range include the use of 12 round wires to connect the solar cells, and larger solar wafers measuring 161.7 mm in size. These ingredients combine to deliver Q CELLS’ “most advanced monocrystalline solar module to date”, the company said.
“By focusing our efforts on closing the cell gaps, we offer to our customers a module range that is perfectly fit for purpose: it boasts extremely high power and efficiency, but is not much oversized nor unwieldy, striking an ideal balance between performance and ease of installation, thus ensuring a supremely competitive LCOE,” Maengyoon Kim, head of EU sales for Q CELLS, said.
