An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

AKCOME, formally Zhejiang Akcome New Energy Technology Co., Ltd., is a Chinese solar manufacturer founded in 2006 and listed on the Shenzhen Stock Exchange since 2011, with products sold across more than 100 countries. The company had previously held BloombergNEF Tier 1 status, but was removed from that list by 2024 amid serious financial headwinds - a subsidiary filed for bankruptcy citing an inability to meet debt obligations, and AKCOME's modules were delisted from major industry tracking registries in early 2025. LONGi Solar, founded in 2000 and headquartered in Xi'an, Shaanxi Province, occupies an entirely different tier of institutional standing. It has maintained continuous BloombergNEF Tier 1 recognition through Q4 2025 and earned a double Tier 1 ranking in Q1 2026 - covering both PV modules and energy storage - a distinction held by very few manufacturers globally. LONGi's institutional footprint in project finance and global procurement is substantially larger and more established than AKCOME's.

AKCOME built its product identity around HJT and PERC cell technology, positioning its panels toward residential rooftops and premium commercial applications where higher efficiency in a compact footprint matters. Prior to the 2024 disruptions, the company also announced early-stage investment in perovskite pilot manufacturing. LONGi's current flagship family centers on the Hi-MO series, led by the Hi-MO X10, a back contact module based on proprietary HPBC 2.0 technology delivering up to 24.8% module efficiency. The Hi-MO lineup spans residential, commercial and industrial, and utility-scale ground-mount segments, making LONGi a credible supplier across essentially every project category.

For most buyers in 2025, LONGi is the straightforward default choice. Its bankability record, active global distribution network, and warranty support infrastructure present far lower long-term risk than AKCOME, whose documented financial instability and loss of Tier 1 status would give pause to any project lender or risk-conscious procurement team.
