The company produces solar cells, modules, inverters, and mounting systems and has reported annual export volumes of around 2 GW of modules and 2 GW of cells and wafers. Its bankability standing has not been confirmed by publicly available BloombergNEF Tier 1 data, placing it in the segment of smaller Chinese suppliers that are technically competent but carry a higher financing risk compared to the industry's top-tier names. AKCOME (Jiangsu Akcome Science and Technology Co., Ltd.) was founded in 2006, was publicly listed on the Shenzhen Stock Exchange from 2010, and at its peak claimed around 3.8 GW of annual module capacity with confirmed BloombergNEF Tier 1 status. However, from mid-2024 onward, AKCOME entered severe financial distress - a subsidiary was ordered into court-supervised bankruptcy reorganization in July 2024, production was suspended at four subsidiaries, and the company was delisted from the Shenzhen exchange after shares fell below CNY 1 for 20 consecutive trading days. As of 2025, JS Solar, despite its smaller footprint, holds the more stable institutional position of the two. On the product side, JS Solar covers a broad catalog that includes PERC-based and TOPCon modules alongside an unspecified share of older technology, spanning power classes from around 200 W up to roughly 670 W and suited to both residential and commercial rooftop installations. AKCOME built its technical identity around heterojunction (HJT) technology - an n-type cell architecture that typically delivers higher efficiency and a better low-light response than standard PERC - alongside a PERC line, targeting the premium end of the residential and commercial market. Its HJT expertise earned it recognition in specialist industry circles, including coverage by dedicated HJT-tracking outlets, but those product lines have been disrupted by the company's financial collapse and the inaccessibility of its main website. For a typical buyer evaluating these two brands in 2025, the choice is not symmetrical. AKCOME's financial and operational distress makes it a serious warranty-risk concern: if the manufacturer cannot honor long-term performance guarantees, any efficiency advantage from HJT technology is undermined. JS Solar is a smaller, mid-market supplier without confirmed top-tier bankability, but it remains an operating business. Buyers who need confidence in a 25-year or 30-year warranty are better served by larger Tier 1 names, but between these two specifically, JS Solar is the more defensible choice in 2025 purely on continuity grounds. \---LINKS--- \- https://www.pv-magazine.com/2024/06/17/akcome-halts-some-manufacturing-faces-possible-chinese-stock-delisting/ \| AKCOME halts manufacturing, faces possible Chinese stock delisting \| article \- https://www.energyconnects.com/news/renewables/2024/july/chinese-solar-firm-forced-into-bankruptcy-as-glut-deepens/ \| Chinese solar firm forced into bankruptcy as glut deepens \| article \- https://www.energysage.com/supplier/20136/js-solar/ \| JS Solar profile and reviews - EnergySage \| review \- https://www.solarquotes.com.au/panels/akcome-review.html \| AKCOME solar panels review - SolarQuotes \| review \- https://comparepv.com/reviews/akcome \| AKCOME Solar Panels Review 2026 - ComparePV \| review Sources: \- \[AKCOME halts manufacturing, faces possible Chinese stock delisting - PV Magazine\](https://www.pv-magazine.com/2024/06/17/akcome-halts-some-manufacturing-faces-possible-chinese-stock-delisting/) \- \[Chinese solar firm forced into bankruptcy as glut deepens - Energy Connects\](https://www.energyconnects.com/news/renewables/2024/july/chinese-solar-firm-forced-into-bankruptcy-as-glut-deepens/) \- \[JS Solar - Profile & Reviews - EnergySage\](https://www.energysage.com/supplier/20136/js-solar/) \- \[Akcome Solar Panels Review - SolarQuotes\](https://www.solarquotes.com.au/panels/akcome-review.html) \- \[AKCOME Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/akcome) Written by claude-sonnet from the figures above. ## Other comparisons - [JS Solar vs A.B.
