The 120-cell half-cut monocrystalline PERC module of Longi Solar has exceeded 360W.

Longi Solar announced that its 120-cell half-cut monocrystalline PERC module has exceeded 360W, as certified by TÜV-Süd. Average cell efficiency reached 22 percent.

This achieves a new world record for the highest power 120-cell half-cut monocrystalline PERC module, adding to Longi’s world record for 60-cell monocrystalline PERC module for power and conversion efficiency. Longi 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 65GW of capacity and about 40 percent of shipments.

Increase yield in low-light conditions

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 percent; 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 performance in low-light conditions and has excellent resistance to hot spots.”

8 GW of PERC cell supply capacity

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, 8GW 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.

Strong R&D investments

“Longi is proud to be a world-class technology-oriented PV manufacturer and is committed to innovations through strong R&D investments across its entire monocrystalline industry chain”, Jun Lv said. R&D spending reached RMB 2.38 billion (USD 380 million) the past 5 years, including RMB 1.108 billion (USD 175.9 million) in 2017 alone.

Li Wenxue, President of Longi Solar added, “Longi has achieved a good balance between high power and high efficiency, focusing and taking the leads in both areas. As a driver and pioneer for high-efficiency and high-quality products, our PERC modules bring customers higher value and return on investment, generate more clean electricity and effectively advance grid parity and the sustainable development of clean energy worldwide.” (HCN)
