The company held BloombergNEF Tier 1 status as recently as Q4 2023 but was removed from that list in 2024, a setback that affects its bankability standing with project financiers. Beyond panel manufacturing, AKCOME owns and operates more than 50 solar farms across the Asia-Pacific region with a combined installed capacity exceeding 1.5 GW, giving it a broader industrial footprint than a pure equipment supplier. DualSun is a French company whose final assembly takes place in Jujurieux, France, earning it a "Made in France" designation, with 70% of the SPRING panel's value sourced from European manufacturing. It does not appear on BloombergNEF Tier 1 lists, reflecting its position as a niche specialist rather than a volume manufacturer. On institutional scale, AKCOME is the larger player by a considerable margin. AKCOME's catalog centers on conventional bifacial photovoltaic panels aimed at commercial rooftops and utility-scale ground mounts, competing on price and volume in a crowded Chinese-dominated segment. DualSun takes a fundamentally different approach with its flagship SPRING product line - a hybrid photovoltaic-thermal (PVT) panel that generates electricity from the front face while an integrated thermal exchanger on the rear captures heat that a standard PV panel would dissipate as waste. The SPRING line uses TOPCon cell technology and is designed primarily for residential installations in Europe, coupling with heat pumps or domestic hot-water systems. In late 2024 DualSun also launched a shingle-format PVT variant optimized for air-to-water heat pump integration. These two brands are not meaningfully interchangeable. A buyer seeking competitively priced bifacial panels for a commercial or utility project would look at AKCOME, bearing in mind its current non-Tier-1 status and the due-diligence implications that carries. A European homeowner wanting to maximize energy yield from limited roof space - covering both electricity and hot water demand - would find DualSun's hybrid approach genuinely differentiated, provided the higher upfront cost and more complex installation align with their budget and system design. \---LINKS--- \- https://www.solarquotes.com.au/panels/akcome-review.html \| AKCOME solar panels independent review - SolarQuotes \| review \- https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/ \| AKCOME Solar Panels - Independent Review by Solar Choice \| review \- https://www.pv-magazine.com/2024/12/17/dualsun-presents-heat-pump-compatible-residential-pvt-panel/ \| Dualsun presents heat pump-compatible residential PVT panel \| article \- https://comparepv.com/reviews/akcome \| AKCOME Solar Panels Review 2026 - Pros, Cons and Specs \| review \- https://hjtpv.com/hjt-producers/akcome-solar-panel/ \| AKCOME Solar Panels - HJT PV Modules overview \| article Sources: \- \[AKCOME Solar Panels Review - SolarQuotes\](https://www.solarquotes.com.au/panels/akcome-review.html) \- \[AKCOME Solar Panels - Solar Choice\](https://www.solarchoice.net.au/products/panels/akcome-solar-panels-review/) \- \[Dualsun presents heat pump-compatible PVT panel - pv magazine\](https://www.pv-magazine.com/2024/12/17/dualsun-presents-heat-pump-compatible-residential-pvt-panel/) \- \[AKCOME Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/akcome) \- \[AKCOME Solar Panels - HJT PV\](https://hjtpv.com/hjt-producers/akcome-solar-panel/) Written by claude-sonnet from the figures above. ## Other comparisons - [DualSun vs A.B.
