The company was at one point listed on BloombergNEF's Tier 1 bankability index, but was removed from that list, and in July 2024 a key subsidiary - Zhejiang Akcome Photovoltaic Technology - entered bankruptcy reorganization proceedings after years of net losses, forced production suspensions, and ultimately a delisting from the Shenzhen Stock Exchange. Zun Power, by contrast, is a Canadian manufacturer based in Montreal that has operated for over a decade under its GMA Solar brand, serving the North American commercial and institutional market at a far smaller scale with no Tier 1 designation. On institutional footprint and historical production scale, AKCOME once held the advantage; that standing has been severely undermined by its financial collapse. Historically AKCOME produced HJT and PERC modules, but both product lines were delisted from industry tracking directories following the inaccessibility of its website and suspension of operations at multiple subsidiaries. Zun Power's catalog spans a wide wattage range - from small off-grid and mobile panels up to bifacial crystalline modules above 650 Wp - using PERC and TOPCon cell technology. The company targets commercial property managers, farmers, municipalities, and construction contractors who need panels certified to Canadian Standards Association and TUV Rheinland standards, including the specialized CSA HazLoc rating for hazardous locations. That North American certification stack, combined with local warehousing, is a genuine differentiator for Canadian buyers. For a typical buyer in 2025-2026, Zun Power is the lower-risk choice by a wide margin. AKCOME's ongoing bankruptcy reorganization creates acute warranty and supply-chain uncertainty that most project developers and lenders will not accept. Zun Power is a niche player without the output scale of tier-1 Chinese manufacturers, but its operational continuity, North American certifications, and focus on commercial and industrial durability make it a credible option for Canadian and US projects where local support and bankability matter more than the lowest possible panel price. \---LINKS--- \- https://www.pv-magazine.com/2024/07/30/chinese-pv-industry-brief-akcome-provides-update-on-restructuring-process/ \| AKCOME provides update on restructuring process - pv magazine \| article \- https://www.bnnbloomberg.ca/investing/commodities/2024/07/30/chinese-solar-firm-forced-into-bankruptcy-as-supply-glut-bites/ \| Chinese Solar Firm Forced Into Bankruptcy as Glut Deepens - BNN Bloomberg \| article \- https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/ \| Akcome Solar Panels - Independent Review by Solar Choice \| review \- https://www.enfsolar.com/zun-power \| Zun Power manufacturer profile - ENF Solar Directory \| article \- https://zunpower.ca/solar-panels-canada-technology/ \| Zun Power - Solar Panel Technology Overview (Canada) \| article Written by claude-sonnet from the figures above. ## Other comparisons - [AKCOME vs A.B.
