## Summary

Silfab is a North American solar manufacturer with roots in Canada and a growing footprint in the United States, where it operates a 1.1 GW module factory in Washington state and a newer cell-and-module campus in Fort Mill, South Carolina that received $100 million in financing in late 2024. The company holds Tier 1 bankable status, validated by third-party labs Kiwa-PVEL and RETC, and earned "Top Performer" recognition in the Kiwa PVEL PV Module Reliability Scorecard for the seventh consecutive year in 2025. AKCOME - formally Jiangsu Akcome Science and Technology - was founded in China in 2006, listed on the Shenzhen Stock Exchange in 2010, and by 2023 had shipped more than 15 GW of modules globally while operating across 30-plus countries. AKCOME appeared on Bloomberg's Tier 1 list as recently as 2022 but was reportedly removed in subsequent updates, and a subsidiary - Zhejiang Akcome Photoelectricity Technology - filed for bankruptcy in 2024, raising near-term bankability concerns. On institutional footprint and financial stability, Silfab currently holds the stronger position.

In terms of product focus, Silfab's lineup is built around N-type TOPCon technology for both the residential and commercial-to-utility segments, with lines such as the Elite series targeting premium domestic rooftop installations and larger commercial modules aimed at ground-mount and community solar projects. AKCOME has positioned itself around HJT cell technology with an entirely bifacial portfolio, making its panels nominally well-suited to utility-scale and ground-mounted applications where rear-side gain can be harvested. The all-bifacial, HJT-centric approach is technically ambitious, though the brand's financial turbulence in 2024 complicates long-term warranty confidence.

For a typical buyer in 2025 - especially in the U.S. market - Silfab is the safer default. Its domestic manufacturing qualifies projects for domestic-content adders under the Inflation Reduction Act, its Tier 1 status is currently intact, and its third-party reliability track record is well-documented. AKCOME may offer competitive pricing and technically interesting HJT panels, but the unresolved bankability questions make it a harder sell where long-term warranty backing matters.
