AKCOME vs S-Energy - solar panel manufacturer comparison

AKCOME, founded in 2003 and headquartered in China, built an aggressive HJT production footprint - reporting a 6 GW panel factory in Huzhou - but the company's parent entity, Zhejiang Akcome Photoelectricity Technology, filed for bankruptcy in 2024 amid the broader Chinese solar price collapse. It was subsequently removed from the BloombergNEF Tier 1 list in early 2025. S-Energy, by contrast, is a South Korean manufacturer established in 2011 with a more modest but reportedly stable manufacturing base of roughly 500 MW per year in Daejeon. Neither company currently holds Tier 1 bankable status, but S-Energy's institutional footprint - a broad 91-panel portfolio versus AKCOME's three listed models, and no reported insolvency proceedings - gives it a meaningfully more secure standing with project lenders.

On paper, AKCOME's portfolio carries the stronger technical specifications. Its average module power of 672 Wp and average efficiency of 21.6%, peaking at 700 Wp and 22.54%, reflect the premium characteristics of its 100% HJT cell lineup. The temperature coefficient of -0.24%/degC is notably gentler than S-Energy's -0.34%/degC, meaning AKCOME panels lose less output during hot field conditions. Every AKCOME panel in the portfolio is bifacial, and the average product warranty runs to 30 years. S-Energy, whose portfolio leans heavily on PERC technology (roughly 59% of models), averages 512 Wp with a peak at 665 Wp and a top efficiency of 22.38%; about 77% of its lineup is bifacial, and average warranty coverage sits near 27.7 years. AKCOME's specs suit high-density rooftop or ground-mount projects where every watt-per-square-metre counts; S-Energy's wider, more varied catalog fits commercial and mid-scale utility buyers seeking a tested, standard-technology option.

For most buyers in 2025, the safer choice is S-Energy, not because its panels are technically superior - they are not - but because sourcing from a manufacturer currently in bankruptcy proceedings introduces real warranty, supply-chain, and financing risk that outweighs the efficiency and power advantage. Buyers who have already locked in AKCOME supply with escrow-backed warranty provisions may still find value in the higher-performing HJT modules, but any new procurement should treat the financial instability as a primary disqualifier until the company's legal situation is fully resolved.
