LONGi Claims Solar Panel Efficiency of 22.38%

Chinese solar manufacturer Longi says it has set a world record for monocrystalline passivated emitter rear contact (PERC) solar panel efficiency, at 22.38%. The figure overhauls the previous landmark of 21.65%, set by Longi last month.

The result, which the solar manufacturer says is a record for monocrystalline solar panels, was confirmed by German testing and certification provider TÜV Rheinland. No details were provided on how the improvement was achieved.

Longi has long dominated the milestones for that type of solar panel and had set a record of 20.83% in November 2018 which at the time beat its previous achievements of 20.66% and 20.41%.

In February 2018, Longi announced a solar panel efficiency of 23.6% for monocrystalline PERC solar cells. That result also surpassed the solar company’s previous record solar panel efficiency of 22.71%, achieved in October 2017.

“Longi has continuously pushed the module efficiency limits of our high performance monocrystalline products to further improve the price-performance ratio,” the solar company announced. “This breakthrough once again confirms the development headroom of monocrystalline module technology.”
