Its roots trace back to 1932 as an electric-heater factory; the company entered renewable energy in 2004 and began automated PV module production in 2012. It operates at a modest regional scale and does not appear on Bloomberg NEF Tier 1 bankability lists, positioning it primarily as a domestic Polish and Central European supplier. AKCOME, founded in China in 2006 and publicly listed on the Shenzhen Stock Exchange since 2010, operates a 6 GW panel factory in Huzhou, Zhejiang province, employs more than 6,000 people, and distributes across more than 30 countries. AKCOME has appeared on Bloomberg Tier 1 lists, though a subsidiary bankruptcy in recent years has raised questions about its current bankability standing. On overall institutional footprint, AKCOME is the significantly larger and more internationally recognized entity. The two brands serve quite different market segments. Selfa's catalog targets residential and smaller commercial installations in Europe, with panels certified by Germany's VDE institute and Italy's KIWA Cermet and marketed on European build quality and a proprietary self-cleaning surface coating. Independent efficiency and technology benchmarking data for Selfa are limited given its relatively small scale. AKCOME has committed heavily to heterojunction - HJT - cell technology across its portfolio, reporting average module efficiencies around 21.6% and top-model figures around 22.5%, along with a 30-year linear power warranty on newer products. The company is also investing in perovskite-HJT pilot production in Hangzhou. That said, AKCOME did not rank as a top performer in PV Evolution Labs' 2024 independent reliability testing, a point prospective buyers should weigh. For most buyers outside Poland in 2025, AKCOME offers greater product choice, broader international service infrastructure, and a technology roadmap anchored in high-efficiency HJT cells. Selfa is a credible option for buyers in Central Europe who prioritize locally manufactured, European-certified modules and value supply-chain proximity over cutting-edge cell technology. The two brands are not interchangeable - they occupy distinct geographic and technology niches. \---LINKS--- \- https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/ \| Akcome Solar Panels - Independent Review by Solar Choice \| review \- https://www.solarquotes.com.au/panels/akcome-review.html \| Akcome Solar Panels Review - SolarQuotes Australia \| review \- https://www.pv-magazine.com/2024/01/02/chinese-pv-industry-brief-akcome-sets-up-pilot-factory-for-perovskite-pv-cells/ \| Akcome sets up pilot factory for perovskite PV cells - pv magazine \| article \- https://www.solarfeeds.com/biz/selfa-ge-s-a/ \| Selfa GE S.A. company overview and Tier 1 status - SolarFeeds \| article Sources: \- \[Akcome Solar Panels - Independent Review by Solar Choice\](https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/) \- \[Akcome Solar Panels Review - SolarQuotes\](https://www.solarquotes.com.au/panels/akcome-review.html) \- \[Akcome sets up pilot factory for perovskite PV cells - pv magazine\](https://www.pv-magazine.com/2024/01/02/chinese-pv-industry-brief-akcome-sets-up-pilot-factory-for-perovskite-pv-cells/) \- \[Selfa GE S.A. company overview - SolarFeeds\](https://www.solarfeeds.com/biz/selfa-ge-s-a/) \- \[AKCOME Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/akcome) Written by claude-sonnet from the figures above. ## Other comparisons - [AKCOME vs A.B.
