Longi unveils most efficient solar module
Longi, a prominent Chinese solar manufacturer, has introduced a cutting-edge hybrid interdigitated back-contact (HIBC) solar module with a remarkable power output exceeding 700W and an impressive production efficiency of nearly 26 per cent.
The unveiling took place at the International Solar Photovoltaic Exhibition (SNEC) in Shanghai, China, where Longi showcased the new module alongside Professor Martin Green from the University of New South Wales in Australia, a renowned figure in the field often referred to as the “Father of Solar Energy.”
Enhanced Performance and Efficiency
The newly revealed solar module by Longi, with dimensions of 2382mm×1134mm, stands out from the competition with a power density exceeding 259W per square metre and an exceptional module efficiency of 25.9 per cent. Despite being 0.4 square metres smaller than other 700W modules on the market, Longi’s innovation offers a power density that is 34W per square metre higher, resulting in an impressive overall power density of 259W per square metre.
Longi’s chairman, Zhong Baoshen, proudly stated, “This is currently the most efficient industrial photovoltaic product in the world. Through the enhancement of efficiency, which we refer to as unit yield, we have truly achieved a balance of high value and reliability.”
Professor Green also commended Longi’s advancements in HIBC technology, highlighting the company’s dedication to innovation in this field. He noted, “We recently updated the world solar cell efficiency list, and LONGi’s HIBC technology claimed the top spot, showcasing the company’s relentless pursuit of excellence in BC technology.”
Setting New Standards in Solar Technology
Longi’s latest module not only solidifies HIBC technology as the most efficient mass-produced solar PV modules but also surpasses the limitations of PERC and TOPCon technologies, thanks to the company’s pioneering work in BC technology. This technological breakthrough was exemplified earlier this year when Longi achieved a new conversion efficiency record for HIBC cells, reaching an impressive 27.81 per cent, a milestone independently verified by the Institute for Solar Energy Research Hamelin (ISFH) in Germany.
