The company claims a combined production capacity of roughly 3.5 GW across three European factories and has expanded into the United States with an assembly facility in Brookshire, Texas, initially rated at 1 GW. Sirius PV is listed on EnergySage and markets itself on bankability credentials, citing a top-in-Europe ranking among financiers. AKCOME - formally Zhejiang Akcome Optronics Science and Technology - was a Chinese manufacturer founded in 2006 and listed on the Shenzhen Stock Exchange in 2010. At its peak the group claimed roughly 3.8 GW of module capacity and held BloombergNEF Tier 1 status, making it a genuine mid-tier global player. However, AKCOME reported net losses continuously from 2019 onward, halted production at several subsidiaries in mid-2024, was delisted from the Shenzhen exchange in June 2024 after shares fell below 1 yuan for 20 consecutive trading days, and a key subsidiary was placed into court-supervised bankruptcy reorganization in July 2024. On institutional footprint today, Sirius PV is the only viable ongoing concern of the two. In terms of product positioning, Sirius PV focuses on half-cut bifacial modules targeting residential rooftops and commercial installations in Europe and, increasingly, the US market, with its Texas origin qualifying some products under domestic-content rules. AKCOME built its later reputation around heterojunction (HJT) cell technology - including a 730 W HJT module unveiled in mid-2023 - and was oriented toward utility-scale and export markets across Australia and Europe. The HJT technology emphasis was a genuine differentiator, but the production lines supporting it are no longer reliably operating. For any buyer in 2025 or beyond, AKCOME cannot be recommended as a new procurement choice. The warranty and long-term service obligations attached to panels from a delisted, partly bankrupt manufacturer carry significant risk, particularly for projects with 25-30 year lifespans. Sirius PV, while a newer and smaller brand than the dominant Chinese tier, is an actively shipping, bankable option with a traceable parent company and US manufacturing presence. Buyers seeking a proven volume supplier at scale should still benchmark Sirius PV against better-established Tier 1 names, but between these two specific brands the choice is straightforward. \---LINKS--- \- https://www.energysage.com/solar-panels/sirius-pv-by-elin-energy/ \| Sirius PV by Elin Energy - solar panel specs and profile \| review \- https://www.pv-magazine.com/2024/06/17/akcome-halts-some-manufacturing-faces-possible-chinese-stock-delisting/ \| Akcome halts manufacturing, faces possible delisting - pv magazine \| article \- https://www.pv-magazine.com/2024/06/21/chinese-pv-industry-brief-akcome-confirms-delisting-from-the-shenzhen-stock-market/ \| Akcome confirms delisting from Shenzhen stock market - 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 supply glut bites - BNN Bloomberg \| article \- https://www.solarquotes.com.au/panels/akcome-review.html \| Akcome solar panels independent review - SolarQuotes \| review Sources: \- \[Sirius PV by Elin Energy - EnergySage\](https://www.energysage.com/solar-panels/sirius-pv-by-elin-energy/) \- \[Akcome halts manufacturing, faces possible delisting - PV Magazine\](https://www.pv-magazine.com/2024/06/17/akcome-halts-some-manufacturing-faces-possible-chinese-stock-delisting/) \- \[Akcome confirms delisting from Shenzhen stock market - PV Magazine\](https://www.pv-magazine.com/2024/06/21/chinese-pv-industry-brief-akcome-confirms-delisting-from-the-shenzhen-stock-market/) \- \[Chinese solar firm forced into bankruptcy - BNN Bloomberg\](https://www.bnnbloomberg.ca/investing/commodities/2024/07/30/chinese-solar-firm-forced-into-bankruptcy-as-supply-glut-bites/) \- \[Akcome solar panels review - SolarQuotes\](https://www.solarquotes.com.au/panels/akcome-review.html) Written by claude-sonnet from the figures above. ## Other comparisons - [AKCOME vs A.B.
