Just Solar vs AKCOME - solar panel manufacturer comparison

Just Solar and AKCOME are both smaller, non-Tier-1 manufacturers operating outside the bankable bracket recognized by lenders and project financiers. AKCOME is headquartered in Zhangjiagang, Jiangsu Province, China, founded in 2003, and has announced planned HJT cell and module capacity in the range of 8 to 13 GW, making it a mid-scale Chinese specialist. It has been rated CC+ by PV ModuleTech - a low-bankability category that signals elevated risk for institutional investors - and as of early 2025 its website became inaccessible, leading to delisting from the TaiyangNews TOP SOLAR MODULES database, which raises supply-continuity concerns. Just Solar's country of origin and production scale are less prominently documented in industry sources, and it likewise carries no Tier 1 bankability standing, giving both brands a similar institutional footprint: suitable for buyers willing to accept higher counterparty risk in exchange for competitive pricing.

At the portfolio level, the two lineups serve quite different market segments despite similar headline efficiency figures. Just Solar offers a broad catalog of 42 panels anchored by TOPCon cell technology in just over half the range, with an average output of 491 Wp, a peak of 740 Wp, and a top efficiency of 23.82% - figures that fit premium residential rooftops and small commercial arrays well. Only about 17% of its panels are bifacial, and the average warranty runs roughly 28.5 years. Its temperature coefficient averages -0.306%/°C, which is adequate but not exceptional in hot climates. AKCOME's sampled portfolio, while much smaller at just 3 panels, is exclusively HJT and 100% bifacial, with an average output of 672 Wp, a peak of 700 Wp, and a 30-year warranty. Its temperature coefficient of -0.24%/°C is meaningfully better, meaning less power loss on hot days. That combination of large-format bifacial modules and a low thermal penalty positions AKCOME's current lineup squarely at utility-scale ground-mount and agrivoltaic applications.

For a typical buyer in 2025, Just Solar is the more practical default: its larger, better-documented catalog gives installers and project developers real product choice, and the TOPCon efficiency ceiling of 23.82% is competitive with mainstream premium brands. AKCOME's HJT bifacial specifications are technically compelling, particularly the temperature coefficient advantage, but the company's recent operational instability - delisting from major tracking databases and a low bankability rating - makes it a difficult recommendation unless a buyer has already secured a confirmed supply chain and verified current panel availability. If AKCOME resolves its continuity issues it would become a strong contender for large ground-mount projects where bifacial gain and low thermal losses materially affect yield; until then, due diligence is essential before committing to it.
