An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

Checking cache...

Resun Solar is a Chinese manufacturer founded around 2005, operating out of mainland China with a reported production capacity in the 500 MW range - placing it firmly in the mid-tier of the global solar supply chain. The company holds ISO 9001 and 14001 factory accreditations and has supplied panels to World Bank-backed projects across Europe, Australia, Africa, and the Americas. No confirmed BloombergNEF Tier 1 designation was found for Resun Solar in available sources. AKCOME (Jiangsu Akcome Industrial Group) was founded in 2006, listed on the Shenzhen Stock Exchange in 2010, and at its peak claimed annual module capacity of roughly 3.8 GW. The company formerly appeared on BloombergNEF Tier 1 lists, but that standing lapsed amid deteriorating finances. In mid-2024, a key subsidiary was placed into court-supervised bankruptcy reorganization, and the Shenzhen exchange terminated AKCOME's listing after its shares fell below 1 yuan for 20 consecutive trading days. AKCOME's website also became inaccessible in early 2025, raising serious questions about its current operational continuity. On institutional footprint and historical scale, AKCOME was the larger player - though that position has been severely undermined by its financial collapse.

In terms of product focus, Resun Solar offers a residential and light-commercial module lineup and, according to available reviews, has incorporated TOPCon cell technology into parts of its current catalog. AKCOME built its identity around heterojunction (HJT) technology - a premium cell architecture that typically delivers higher efficiency and better low-light performance - and offered an exclusively bifacial, double-glass module range. AKCOME also sold complementary aluminium racking and mounting systems as a secondary business line.

For a buyer evaluating both brands in 2025, Resun Solar is the more prudent default choice despite its smaller scale. AKCOME's financial distress, delisting, and uncertain operational status make it a high-risk procurement decision regardless of its technology credentials. Resun Solar's situation is more stable, though buyers should verify local distributor support and warranty backing before committing, as neither brand carries the institutional depth of top-tier manufacturers.
