TÜV-SÜD announced that LONGi Solar’s 120-cell half-cut monocrystalline PERC module has exceeded 360 W, which would be a new world record for the highest power 120-cell half-cut monocrystalline PERC module. This adds to LONGi’s world record for 60-cell monocrystalline PERC module for power and conversion efficiency.

LONGi’s singular focus on PERC technology significantly reduces the LCOE, thereby advancing grid parity and raising the technological bar in PV. PERC has emerged as a focus technology point, especially in China’s “Top Runner” projects. Experts predict that by 2020, PERC will account for 65 GW of capacity and about 40 percent of shipments.

Dr. Jun Lv, Vice President of LONGi Solar, explained, “LONGi Solar’s 120-cell half-cut monocrystalline PERC module applies our leading PERC technology. Average cell efficiency reached 22%; degradation in the first year is less than 2%, and stabilizing at less than 0.55% per year. PERC has been proven to increase power generation per-formance in low-light conditions and has excellent resistance to hot spots.”

LONGi is accelerating the upgrade of its solar cell production line and expects to complete the move to PERC this year. Concurrently, through strategic cooperation, 8 GW of PERC cell supply capacity will be available to fully meet market demand for high-efficiency products. The company will gradually phase into mass production its world record monocrystalline products.
