AIKO-A660-MDE72Mw

Top 24% of the Back Contact 650-700 W segment, against a median of 49.7.

The ABC (All Back Contact) technology allows for a module efficiency of 24.2–25.2%, while comparable modules from SpolarPV, Solaria, and Vikram Solar (SPV680, PARADEA) have efficiencies of 21.89–21.92%. This represents a gain of 2.3–3.3%, which directly translates to higher power output from the same roof or ground area.

The temperature coefficient of Pmax is -0.26%/°C, compared to -0.30%/°C for typical TOPCon modules and -0.35%/°C for PERC modules. At a module temperature of 70°C (a realistic summer in Poland), the difference compared to PERC on a 680W module is approximately 9-10W less in actual power loss – which is significant for commercial and industrial installations that operate for many hours during the peak of summer.

The manufacturer guarantees ≤1% degradation in the first year (LID) and ≤0.35%/year in subsequent years, with a retention of 90.6% after 25 years and 88.85% after 30 years. For comparison, a standard Tier-1 PERC/TOPCon offering typically achieves 84.8% after 25 years – the difference in cumulative energy yield over the lifespan is measurable in thousands of kWh per inverter.

The back-contact architecture eliminates busbars and metallic fingers from the active surface of the cell, thereby removing the primary cause of micro-crack degradation and hot-spot formation due to partial shading. For large modules installed in industrial halls (where the risk of point contamination is high), this represents a real operational advantage.

AIKO is listed on the BNEF Tier 1 PV Module Manufacturers (Q1 2026) list, which is a formal requirement for obtaining bank financing for PV farm and large C&I project installations. Tier 1 status signifies documented deliveries to at least 6 projects exceeding 10 MW, financed by independent commercial banks, over the past 24 months.

The Comet 3N72 series is a single-glass design, which eliminates reflection from the ground. On ground-mounted farms with a light-colored surface, bifacial modules typically generate an additional 5–15% of energy. AIKO offers bifacial ABC variants in the Stellar 3N+72 and Comet 3N+72 series – for ground-mounted installations, it is worth considering these series instead of the Comet 3N72.

The standard product warranty is 15 years (with the option to extend it to 25 years under separate terms), while some Tier-1 manufacturers, such as Longi Hi-MO X10 and Canadian Solar HiKu7, offer 25 years as standard without any additional costs. For projects with long financing terms, a separate analysis of the terms of extension may be required.
