42 JA N UA RY / F E B RUA RY 2 0 1 9 Hanwha Hanwha's new Q.PEAK DUO BLK-G6 module will be assembled in the U.S. at Hanwha Q CELLS' new Dalton, Ga., module facility — the largest module manufacturing facility in North America — slated for completion in January. The 6x20 monocrystalline Q.ANTUM half-cell design allows for higher yield per surface area and higher power classes. The Q.PEAK DUO is ideal for residential applications. Warranty: 12-year product, 12-year linear performance. LONGi The combination of elements in LONGi's Hi-MO — a half-cut, p-type, monocrystalline PERC, bifacial module — is compelling. LONGi says the bifaciality results in a 10 to 25 percent higher yield at a cost similar to a monofacial PERC module. The bifaciality factor, which is the ratio of efficiency on the rear side as compared to the front, is upward of 75 percent. These are ideally suited for utility power plants and commercial rooftop applica- tions and areas with a greater surface albedo. Warranty: 30-year for extra linear power out- put, 10-year for materials and processing.
