The AIKO N-Type ABC White Hole (AIKO-A-MAH72Mw) series maximizes roof surface utilization through its All Back Contact (ABC) architecture - free of front busbars, enhancing light absorption and providing a distinctly cleaner, uniform aesthetic. The application of N-type cells helps minimize typical power losses over time and stabilize module performance under real-world conditions, especially during summer operation at high temperatures.

This series is designed for investors seeking more energy from the same surface area - ideal for residential roofs, commercial buildings, and projects where high power density and appearance are key (e.g., visible installations, premium buildings). In practice, the module reduces stress on construction structures and cabling, as achieving the projected yield requires fewer panels - a tangible advantage in limited spaces. What sets it apart from the competition is its front electrode-free surface, high operational efficiency in high temperatures, and low degradation rate, facilitating long-term annual production planning.

What owners get
Efficiency of 23.2–24.0% – leading the segment

The series achieves up to 24.0% module efficiency, exceeding all three comparable products: HT-SAAE HT66-18X (23.0%), Weran Solar LR7-72HTH (23.0%), and MY Solar G&A TOPCon (22.95%). AIKO maintains the top position in the TaiyangNews Top Solar Modules ranking for over 34 months, confirming the industry-wide consistency of this level of efficiency.

Low temperature coefficient of -0.26%/°C

The ABC technology eliminates the front metal contacts, reducing carrier recombination and lowering the temperature coefficient to -0.26%/°C. Standard TOPCon and PERC modules in this power class exhibit a temperature coefficient of -0.30 to -0.35%/°C, which translates to a real increase of 4–9% in energy yield on days when module temperatures exceed 60°C.

Degradation ≤0.35%/year and a 30-year power warranty

The manufacturer guarantees ≥88.85% of the nominal power after 30 years, with a degradation rate of ≤0.35% per year (after the first year). Comparable products in the same segment do not publish degradation rates as low as this – typically 0.40–0.45%/year for TOPCon, which, when installed at 620 Wp, translates to a real increase of tens of kWh per year over a 25–30 year period.

ABC Architecture – a clean front without electrodes

The absence of front current paths eliminates internal shading at the cell level and improves light absorption at low angles of incidence (morning/evening). According to independent tests (TaiyangNews/Strategic Energy), ABC modules generate 4.9–50% more energy under partial shading compared to equivalent TOPCon modules.

Tier-1 manufacturer (bankable according to BNEF)

AIKO is listed on the Bloomberg NEF's list of bankable manufacturers, which facilitates obtaining project financing and acceptance by insurance companies. The company has been operating since 2009, has its own production lines for ABC cells, and is independent of the technology licenses of its competitors.

Trade-offs
Product line discontinued (2023)

The AIKO-A-MAH72Mw series, with a power output of 600–620W, has been discontinued and replaced by the Comet 1N (590–615W) series, as well as newer generations with higher efficiency ratings. This means that new modules for potential system expansion are now limited in availability, that matching power output may be challenging when replacing individual panels, and that active technical support for this specific series is no longer available.

Absence of bifaciality vs. peer comparison

The series is monofacial (is_bifacial: false), while its direct equivalent – MY Solar G&A N-Type TOPCon Bifacial 620 Wp – offers bifaciality, providing an additional 5–15% yield in ground-mounted installations with a reflective surface or white membrane roofs. This represents a significant disadvantage when calculating LCOE (Levelized Cost of Electricity) for commercial and industrial (C&I) and utility projects.

The product warranty is only 15 years.

The warranty for the product is 15 years, while the newer AIKO Neostar (ABC, using the same technology) line offers a 25-year product warranty. In the premium segment, institutional and project-financing banks increasingly require a minimum of 20-25 years – a shorter period can negatively impact financing terms.

Common questions

6 answered
Is the AIKO N-Type ABC White Hole (AIKO-A-MAH72Mw) series still available for sale?
The AIKO-A-MAH72Mw series has been discontinued and is no longer offered as an active product within the AIKO portfolio. Availability from distributors may be limited to remaining stock. If you are looking for a comparable ABC technology from AIKO, it is worth exploring newer series such as Comet or Nemo, which continue to use the same All Back Contact cell architecture.
What does the "ABC technology" refer to in AIKO AI panels, and why do they not have electrodes on the front?
ABC (All Back Contact) is a technology in which all electrodes have been moved to the back surface of the cell. This eliminates the grid of metallic current paths on the front of the module, increasing the active light-absorbing surface and improving aesthetics. As a result, the AIKO-A-MAH72Mw series achieves efficiencies of up to 24%, and the module has a uniform, dark appearance without visible silver strips.
What is the warranty on Aiko N-Type ABC White Hole panels, and what does it cover?
The manufacturer provides a 15-year product warranty (for physical and material defects) and a 30-year linear power warranty. Over the 30-year period, the power degradation should not exceed 0.35% per year after the first year, during which a 1% reduction is permitted. This means that after 30 years, the module should maintain at least approximately 87% of its nominal output power.
How does the AIKO-A-MAH72Mw 620W panel perform in high summer temperatures?
N-type cells, combined with the ABC architecture, provide a temperature coefficient for Pmax of approximately -0.29%/°C, which is significantly better than standard P-type panels (-0.35% to -0.40%/°C). In practice, this means lower power losses on hot days – the panel operates more stably and produces more energy compared to cheaper conventional modules with the same rated power.
How many Aiko-A-Mah72Mw 620W solar panels do I need to install a 10 kWp system on my home?
With a maximum power of 620 W per module, only 17 panels are needed to achieve an installation exceeding 10 kWp (17 × 620 W = 10.54 kWp). This is 3-5 panels fewer than with popular 400-450 W modules. A smaller number of panels translates to real savings on the mounting structure and wiring, while also providing greater flexibility on roofs with limited space.
Are AIKO White Hole series MAH72Mw panels suitable for a sloped roof with limited surface area?
Yes, its high power density (efficiency ~24%) and lack of front-mounted electrodes make this series particularly attractive for sloped roofs, where maximizing power output per square meter is crucial. The module has dimensions of 2278 x 1134 x 30 mm and weighs 27.1 kg, which conforms to typical standards for roof-mounted structures. Its uniform, black aesthetic also works well on visible premium roof tiles.
