AIKO vs TCL - solar panel manufacturer comparison

AIKO and TCL are both Chinese solar manufacturers, though their institutional profiles differ considerably. AIKO was founded in 2009, is publicly listed on the Shenzhen Stock Exchange (SZSE), holds BloombergNEF Tier 1 bankable status as of Q3 2024, and operates around 20 GW of module production capacity. TCL's solar division draws on the resources of the broader TCL Group - a conglomerate tracing its origins to 1981 - and has expanded to roughly 40 GW of module capacity, but the solar unit does not currently carry Tier 1 bankable status. For project-financed deals where lender confidence in manufacturer longevity matters, AIKO's Tier 1 rating gives it a meaningfully stronger institutional footprint.

The two lineups target quite different installation types. AIKO fields a large catalogue of 144 models, with an average output of 581 Wp and a peak of 805 Wp, built predominantly around its proprietary All Back Contact (ABC) cell technology, which accounts for 73.6% of the portfolio. Average panel efficiency sits at 23.65%, reaching up to 25.2% at the top of the range, with a temperature coefficient of -0.27%/degrees C - among the best in commercial production. Only 24.3% of AIKO's panels are bifacial, making the lineup better suited to premium space-constrained rooftops, whether residential or commercial. TCL's far smaller catalogue of 12 models is built entirely on TOPCon cells, all panels are bifacial, and average output is a higher 665 Wp (peak 725 Wp) - a profile aimed squarely at utility-scale and large ground-mount applications. Average efficiency is 22.9%, topping out at 23.3%, with a slightly softer temperature coefficient of -0.285%/degrees C. TCL offers a 30-year performance warranty, a marginal edge over AIKO's average of 29.5 years.

For most buyers in 2025, AIKO is the safer default - its Tier 1 status eases project finance, its efficiency lead is real and well-documented, and its broader model range supports more installation contexts. TCL's 100% bifacial, high-wattage lineup is genuinely competitive for open-field utility projects where bifacial gain matters, but the absence of Tier 1 bankability raises the bar for due diligence that AIKO clears automatically.
