The company built its reputation around heterojunction (HJT) cell technology and is widely cited as one of the highest-volume HJT producers globally. It held BloombergNEF Tier 1 bankability status but was removed from that list around Q1 2024, a shift that affects its standing with project finance lenders even though it does not reflect panel quality directly. By 2023 the company had reported cumulative shipments exceeding 15 GW and cell production capacity of roughly 10-11 GW per year, placing it in the mid-tier of global volume producers. AKCOME also announced a joint-venture gigafactory in the United States targeting 1.2 GW of initial module and cell capacity, with HJT expansion planned thereafter. Green Energy Supplier, by contrast, is a Bulgarian distribution company founded in 2015 and headquartered in Bulgaria. It is listed on ENF Solar as a seller - not a manufacturer - and acts as an authorized regional distributor for global brands including LONGi, Risen, Huawei, Solis, and Deye. It does not produce panels under its own brand. AKCOME therefore carries the stronger institutional manufacturing footprint of the two. AKCOME's product portfolio centers on its iTopper TOPCon series and its HJT-based modules, targeting commercial rooftop, utility-scale ground-mount, and increasingly residential applications with high-wattage formats in the 655-700 W range. Green Energy Supplier does not manufacture panels and has no proprietary product family; its value proposition lies in local logistics, warranty support, and access to the brands it distributes in the Bulgarian and broader Balkan market. These two entities are not directly comparable as peers. A buyer evaluating solar panels should treat AKCOME as the panel brand under consideration and Green Energy Supplier as a possible regional channel through which panels from various brands - potentially including AKCOME - could be procured. If the choice is strictly between buying AKCOME-branded hardware versus sourcing through Green Energy Supplier's portfolio of distributed brands, the decision hinges on which manufacturer's product Green Energy Supplier is offering for a specific project, not on the distributor itself. \---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 \| review \- https://comparepv.com/reviews/akcome \| AKCOME Solar Panels Review 2026 - Pros, Cons and Specs \| review \- https://www.enfsolar.com/green-energy-supplier \| Green Energy Supplier - ENF Solar Company Profile (Bulgaria) \| article \- https://www.renvu.com/blogs/learn/tier-1-solar-panels-list-2025-updated-manufacturers-rankings \| Tier 1 Solar Panels List 2025 - Updated Manufacturers and Rankings \| article Sources: \- \[AKCOME Solar Panels - Solar Choice\](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) \- \[AKCOME Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/akcome) \- \[Green Energy Supplier - ENF Solar\](https://www.enfsolar.com/green-energy-supplier) \- \[Tier 1 Solar Panels List 2025 - RENVU\](https://www.renvu.com/blogs/learn/tier-1-solar-panels-list-2025-updated-manufacturers-rankings) Written by claude-sonnet from the figures above. ## Other comparisons - [AKCOME vs A.B.
