AIKO Neostar 2P (AIKO-A-MAH54Mw) are modules based on N-type ABC (All Back Contact) cells, meaning a construction without front busbars and conventional metal mesh interconnection. In practice, this means better light utilization and a cleaner, uniform front appearance - particularly valued in rooftop installations for homes and premium buildings. The applied architecture also helps reduce losses associated with temperature, ensuring more stable performance during hot days when many competing panels noticeably lose power.

The Neostar 2P is distinguished by high resistance to microcracks, which is important for long-term operation, transportation, and use on structures exposed to stress. Users also benefit from lower degradation over time, meaning greater predictability in energy production over years and easier planning for investment profitability. This is an excellent choice for those who wish to maximize the use of limited rooftop space and for companies where high output per square meter is crucial. Thanks to its refined aesthetics and ABC technology, the series clearly stands out from standard PERC and classic TOPCon modules.

What owners get
Record-breaking efficiency of ABC – up to 24.3%

The All Back Contact technology (no metal grid on the front) allows for efficiency levels up to 24.3%, which is comparable to the best competitors in the segment (Gokin GK-5-54HG: 24.3%) and significantly exceeds the ZNShine ZXM7-UHLD120 (22.47%). AIKO holds the world record for mass production at 24.4% (TaiyangNews, June 2025), which confirms the real potential of the technology in practical applications.

Low thermal expansion coefficient: -0.26%/°C

The temperature coefficient of -0.26%/°C is significantly better than typical TOPCon (-0.30%/°C) and PERC (-0.35%/°C) modules. In Polish conditions, where the roof can heat up to 60-70°C in the summer, this difference translates into a significantly higher summer yield without incurring additional costs.

Low degradation: ≤0.35%/year from the 2nd year

The declared degradation of ≤1% in the first year and ≤0.35%/year in years 2-30 is better than typical TOPCon (≤0.4%/year) and PERC (≤0.45%/year) modules. Over a 30-year lifespan, this difference accumulates to several percentage points more energy production.

30-year linear power guarantee

The manufacturer offers a 30-year linear power guarantee and a 25-year product guarantee – exceeding market standards (comparable companies Gokin and ZNShine do not publish comparable 30-year guarantee terms). This provides the investor with a longer period of predictable cash flow from the installation.

BNEF Tier-1 Award, InterSolar 2023 Prize

AIKO is listed on the Tier-1 BloombergNEF list (validated for Q1 2026), which is crucial for securing commercial financing. The Neostar 2P series won the Intersolar Award 2023, confirming the independent validation of ABC technology by industry experts.

Trade-offs
This series does not have a dual-sided version.

The AIKO-A-MAH54Mw series is monofacial only (is_bifacial: false), while AIKO offers parallel versions with dual glass (Neostar 2P+ Dual-Glass). For installations on bright surfaces (gravel, concrete, snow), the installer loses the potential gain from reflection, which is available, for example, in bifacial modules from the TOPCon segment.

Common questions

6 answered
What distinguishes the ABC technology used in Aiko Neostar 2P panels from standard PERC and TOPCon modules?
The ABC (All Back Contact) technology moves all electrodes to the back of the cell, eliminating front busbars and metallization grids. This allows for more of the cell surface to absorb light, resulting in higher efficiencies of up to 24.3% in the Neostar 2P series. PERC and TOPCon modules have electrodes on the front, which partially cover the active surface and reduce their performance potential.
What is the warranty for Aiko Neostar 2P panels, model A-MAH54Mw?
The Neostar 2P series comes with a 25-year product warranty covering material and workmanship defects, as well as a 30-year performance warranty. Degradation is no more than 1% in the first year and a maximum of 0.35% per year in years 2-30. This means that after three decades, the module should still be operating at a power close to 87% of its nominal value.
What is the maximum power output of Aiko Neostar 2P solar panels, and is it sufficient for a typical single-family home?
The top-of-the-line model in the series achieves a power output of 485 Wp with an efficiency of up to 24.3%. For a home with an annual consumption of approximately 4000 kWh, it typically requires 8-10 such modules (approximately 4-5 kWp). The high individual power output means that you need fewer panels, or you can generate more energy from the same number of modules compared to standard 400-420 Wp units.
Do the Aiko Neostar 2P solar panels experience a significant loss of power on hot, sunny days?
The N-type ABC technology is characterized by a lower temperature coefficient than P-type PERC cells, which means less power loss at high temperatures. In practice, when the roof heats up to 60-70°C in the summer, Neostar 2P modules lose less energy than typical PERC modules, resulting in more stable and higher yields during the summer months.
Are the AIKO Neostar 2P solar panels suitable for a small roof with limited surface area?
Yes, this is one of the main reasons for choosing this series. With an efficiency of up to 24.3% and a power output of 485 Wp in a 54-cell format, it allows for generating more energy per square meter than standard modules. If you have a roof with an area of 20-30 m², the difference compared to cheaper 400 Wp modules could be several hundred kilowatt-hours per year.
Are Aiko Neostar 2P panels bifacial, and can they be mounted on a freestanding structure with reflected light from the ground?
No, the AIKO-A-MAH54Mw Neostar 2P modules are monofacial – energy is generated solely from the front side of the panel. Therefore, you won't benefit from the albedo effect (reflected light) as you would with bifacial modules. However, these modules are perfectly suitable for standard rooftop installations, where bifaciality wouldn't offer significant advantages due to the lack of access to light on the back side.
