This translates to greater power output from the same roof or ground area – which is particularly important when space is limited. - **Exceptional temperature coefficient** - The Pmax coefficient is -0.22%/°C (AIKO-A-MAH72Dw G datasheet), which is significantly better than standard TOPCon modules (-0.29%/°C) and competing bifacial N-type modules (~-0.26%/°C). At the module's operating temperature of 70–80°C (typical for summers in Poland), this difference translates to a real increase of 1.5–2% in daily energy yield compared to the competition. - **ABC – an advantage in shaded conditions** - The All Back Contact technology eliminates front-side busbars, which reduces shading losses and hot spots. According to the manufacturer's data and TÜV Rheinland certification (Class A shading resistance), the module can generate up to 30% more energy than a standard TOPCon module with shading of a single cell – a unique feature in this power class. - **Low degradation + 30-year power warranty** - The manufacturer guarantees a degradation rate of ≤1% in the first year and ≤0.35% per year from the 2nd year onwards, which, with a 30-year power warranty, provides a level of predictability rarely seen in comparable series. Comparable products from DAH and Leapton typically have a lifespan of 25-27 years or a worse annual degradation rate. - **Tier-1 bankable, active since 2023** - AIKO is listed on the bankability (Tier-1) list, which facilitates project financing. The product line remains active and is not discontinued, and the manufacturer is investing in subsequent generations (Gen III INFINITY, with 25% efficiency in 2024), which reduces operational risk over a 30-year horizon. ## Cons - **A lower bifaciality ratio compared to TOPCon** - The datasheet confirms a bifaciality factor of 65±5%, while LONGi Hi-MO 7 achieves ~80%, and typical TOPCon bifacial modules – 80–85%. In ground-mounted installations with high albedo (light gravel, snow, light membrane), this means a realistically smaller yield from the rear side of 2–5% compared to the competition, which partially offsets the advantage resulting from higher front-side efficiency. - **Price premium within the TOPCon segment** - The ABC technology requires specialized production lines, which translates to a higher price, estimated to be 10–20% higher than comparable TOPCon tier-1 modules (e.g., LONGi Hi-MO 7 or DAH). For a typical PV farm, where the cost of initial investment (CAPEX) per kWp is optimized, this difference requires an IRR analysis specific to the location and solar radiation profile. ## About this series The AIKO N-Type ABC Dual-glass Bifacial Module is designed for maximum yield where every square meter counts, alongside stable performance over time. Its key advantage is the **ABC (All Back Contact)** technology - free from front busbars and "cell shading" on the surface, enabling more efficient light utilization while maintaining a uniform appearance. In the **bifacial** version, the module operates on both sides, effectively boosting yield from reflections off light-colored ground, roofs, gravel, or structures - translating to a better energy balance without increasing installation footprint. The **dual-glass** (glass-glass) construction enhances durability, rigidity, and resistance to external conditions, while simultaneously helping mitigate operational risks associated with degradation and high-temperature operation. In practice, this is the series for investors seeking **lower LCOE** and predictable outcomes - especially in utility-scale PV farms, ground-mounted installations, projects in uneven irradiance areas, and floating or more demanding applications. Thanks to solutions focused on minimizing partial shading losses and risk control of hot-spots, these modules distinctly differentiate themselves from conventional TOPCon/PERC constructions under real operating conditions. ## Notable figures - Efficiency of 23.7% is 0.9pp above the \*\*N-type 600-650W\*\* median (22.8%) - 237.3 W/m² power density - 9.6 W/m² more than \*\*N-type 600-650W\*\* median (227.7 W/m²), more power per roof area - Temperature coefficient of -0.29%/°C matches the \*\*N-type 600-650W\*\* median - Bifacial design (55% factor) captures reflected light - adds 3-8% yield on ground-mount or white roof - #517 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What is the ABC technology used in AIKO panels, and how does it differ from the popular TOPCon technology? ABC (All Back Contact) means that all the electrical connections of the cell are located on its back. The front surface is completely free of busbars, allowing for more light to reach it and achieving an efficiency of up to 23.7%. Standard TOPCon panels still have visible busbars on the front, which cause minor losses due to shading. In practice, this translates to a higher yield from the same roof or ground area. ### What warranty does the AIKO N-Type ABC Dual-glass Bifacial Module series offer? The manufacturer provides a 15-year product warranty covering material and workmanship defects, as well as a 30-year performance warranty. Degradation is limited to just 0.35% per year for the first 30 years of operation, after the first year, ensuring predictable energy production throughout the entire investment period. Both warranties are standard for Tier 1 modules from Aiko. ### Does the Aiko ABC bifacial solar module actually produce more energy, and when is it cost-effective? Yes, provided that the back side of the module has access to diffused or reflected light. Installations on a light-colored gravel, concrete, or a light-colored roofing membrane, or structures like floating platforms, can achieve a real energy gain of several to fifteen percent. The brighter the surface and the larger the space under the panel, the more noticeable and faster the bifacial effect becomes, and the quicker the module's cost is recouped. ### How do the AIKO N-Type ABC Dual-glass series perform in hot weather and at high operating temperatures? The N-type ABC technology is characterized by a low temperature coefficient of power, approximately -0.26%/°C, which is better than most PERC panels and comparable to the best TOPCon panels. This means that on a hot day, when the cell temperature is around 65°C, the module loses less power than typical P-type cells. The dual-glass design further reduces the risk of thermal degradation and hot spots over the long term. ### Are Aiko N-Type ABC Dual-glass solar panels with a 625W output suitable for large-scale photovoltaic farms and ground-mounted installations? Yes, the series is clearly positioned for PV farms and ground-mounted installations. A power output of 625W with a format of 2323×1134 mm allows for a reduced number of modules and connections per string, which lowers BOS (Balance of System) costs. The high resistance of the dual-glass module to moisture, mechanical loads, and PID degradation makes it suitable for even more challenging environments, including floating installations. AIKO is listed on Tier 1, which facilitates financing from banks. ### Can the AIKO ABC 625W module be connected to standard inverters and optimizers available on the market? Yes, the modules are equipped with MC4-compatible connectors and work with standard string and hybrid inverters available in Poland (SMA, Fronius, Huawei, SolarEdge, and others). When installing with optimizers or microinverters, it's important to check the maximum input current of the inverter, as ABC cells generate a higher short-circuit current than typical PERC cells. Before selecting, it's advisable to verify the electrical parameters with the module's technical specifications. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/N-Type-ABC-module-Aiko-A-MAH72Dw-G-605-625W-en-897dcb7ec6a0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +1.5 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +1.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +1.1 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +1.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.1 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, cooler, +1.1 pp | | [AIKO AIKO-A605-MAH72Dw G](https://comparepv.com/panel/aiko-aiko-a605-mah72dw-g) | 605 W | -20 W, -0.7 pp | | [AIKO AIKO-A610-MAH72Dw G](https://comparepv.com/panel/aiko-aiko-a610-mah72dw-g) | 610 W | -15 W, -0.5 pp | | [AIKO AIKO-A615-MAH72Dw G](https://comparepv.com/panel/aiko-aiko-a615-mah72dw-g) | 615 W | -10 W, -0.4 pp | | [AIKO AIKO-A620-MAH72Dw G](https://comparepv.com/panel/aiko-aiko-a620-mah72dw-g) | 620 W | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +55 W, lighter, +1.5 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a625-mah72dw-g Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
