Top 1% of the N-type 600-650 W segment, against a median of 22.77%. Ranked 303rd in the whole database.

Top 1% of the N-type 600-650 W segment, against a median of 227.7. Ranked 332nd in the whole database.

Top 6% of the N-type 600-650 W segment, against a median of 52.7. Ranked 749th in the whole database.

The efficiency of up to 24% significantly surpasses direct competitors: HT-SAAE HT66-18X(ND)-F and Weran Solar LR7-72HTH, which achieve 23%, and MY Solar G&A TOPCon Bifacial at 22.95%. The ABC technology eliminates shading caused by collective rails, maximizing the active surface area – this is the main reason for the ~1 percentage point efficiency advantage without increasing the module size.

The temperature coefficient of -0.26%/°C is approximately 35% better than the industry standard for TOPCon and PERC cells (~-0.40%/°C). On hot days, when the cell temperature reaches 65-70°C, AIKO loses approximately 10% of its power, while standard TOPCon cells lose approximately 15-16%. This translates into a significantly higher annual yield in the Polish climate (peak production season).

The manufacturer guarantees a degradation of ≤1% in the first year and ≤0.35%/year in years 2-30, compared to the typical 0.40-0.45%/year degradation rate for Tier-1 TOPCon modules. After 30 years, this means maintaining at least ~88% of the nominal power, which, at 620 W, yields approximately 545 W – a significant difference in the long-term financial balance of the installation.

The warranty on power parameters is 30 years, while most comparable TOPCon models on the market (e.g., MY Solar, Weran Solar) offer standard 25-year warranties. The extended warranty directly reduces the financial risk for the investor and is a key argument when seeking bank financing for C&I projects.

AIKO is listed on the BNEF's bankable tier-1 list and has a European subsidiary – AIKO Energy Germany GmbH, based in Düsseldorf – which provides local technical and service support for the EU/PL market. This distinguishes AIKO from smaller brands without a European infrastructure.

The series is monofacial, while the direct competitor – MY Solar G&A N-Type TOPCon Bifacial – offers the same power output of 620 W with bifaciality. When installed on a light-colored surface or on a light-colored flat roof, bifacial modules can achieve an additional 5–15% power gain from the back side, which could offset the efficiency advantage of AICO in certain installation scenarios.

The warranty on the product (material defects, workmanship) is 15 years, which is below the standard of 25 years offered by leading tier-1 manufacturers (JA Solar, Trina, Longi). For commercial installations financed with credit or leasing, a shorter product warranty period may be a formal obstacle in the risk assessment process by a bank or insurance company.

The ABC technology has historically been more expensive than TOPCon. Although the price difference is narrowing in 2026 (rising silver prices affecting TOPCon, while ABC uses copper metallization), AIKO continues to be positioned in a higher price range compared to comparable 620 W TOPCon modules from HT-SAAE or Weran Solar. This may not be justified in typical low-priority residential installations where minimizing roof space is not a primary concern.
