AIKO Neostar (AIKO-A-MAH54Db) was designed to achieve maximum energy yield from the same rooftop surface - where every square meter counts and real energy production under varying conditions is key. The key difference is the application of ABC (all-back-contact) technology, or a cell architecture without visible front connections. This allows the module to utilize light more effectively while simultaneously offering a uniform, aesthetically pleasing surface - especially important in premium projects.

Neostar also features N-type cells, selected when investors expect stable performance over the years and reduced sensitivity to typical degradation phenomena. In practice, this translates to a more predictable yield and easier planning for self-consumption.

In everyday use, you'll notice optimized performance under partial shading, which is useful on rooftops with chimneys, gable ends, or nearby trees. The glass-glass construction increases resistance to environmental conditions and micro-cracks, while full black facilitates matching modern architecture. This is a series for single-family homes and small commercial installations, where efficiency and appearance hold equal importance.

What owners get
Efficiency of 23.3% – leading the comparison group

The module achieves an efficiency of 23.3%, surpassing comparable models such as Sunlike SKT455 and IBC Solar LS-TA2 (both 22.8%, +0.5 pp), as well as Waaree ARKA (20.93%, +2.37 pp). This means a higher power output from the same roof area, without the need to install additional panels.

Temperature-dependent maximum power coefficient: -0.26%/°C

The ABC N-type technology offers a temperature coefficient of −0.26%/°C, which is significantly better than typical TOPCon (−0.35%/°C) or PERC (−0.45%/°C). This translates to a significantly higher energy yield on hot, summer days – precisely when the installation has the greatest opportunity to generate the most energy.

30-year linear warranty with a degradation rate of ≤0.35%/year

The manufacturer guarantees a degradation rate of less than 1% in the first year and ≤0.35%/year in subsequent years – over a 30-year warranty period. Comparable products (Waaree ARKA, Sunlike SKT) offer standard 25-year warranties, which, when calculating the Levelized Cost of Energy (LCOE) over a 25–30-year period, makes this series more financially attractive.

ABC: 100% active surface area of the cell

The absence of electrodes on the front of the cell (All Back Contact) eliminates shading losses from metallic pathways and maximizes photon absorption. Since March 2023, AIKO has consistently held the top position in TaiyangNews' Top Solar Modules ranking for mass production efficiency (current record: 24.8% for a commercial module).

Glass-glass construction with certified durability.

The dual-layer construction increases resistance to micro-cracks, moisture, and mechanical stress compared to standard glass-foil modules. For roofs with large temperature fluctuations or exposure to moisture (coastal or mountainous climates), this represents a significant advantage over modules with a backsheet.

Trade-offs
Only one power option available (455 Wp)

The scope of this series includes only the 455 W version, without the option to choose a lower or higher power within the same series. Installers designing systems with an unconventional number of modules or limited space may find it difficult to optimize their choice without combining it with another series.

Single-sided glass

The module has a glass-glass construction, but does not utilize bifaciality (is_bifacial = false). In ground-mounted or rooftop installations using light-colored materials, where a light surface typically provides an additional 5-15% gain, a glass-glass module without bifaciality does not fully realize the benefits of this design.

Common questions

6 answered
What is the warranty on Aiko Neostar AIKO-A-MAH54Db panels?
The AIKO Neostar series is covered by a 25-year product warranty (for physical defects and workmanship) and a 30-year performance warranty. After 25 years, the manufacturer guarantees that the panel will maintain at least 90.6% of its nominal power, and after 30 years, a minimum of 88.85%. This is one of the longest and most stringent warranty packages available on the photovoltaic panel market, which directly translates into predictable returns on investment.
What is the ABC technology used in AIKO Neostar panels, and is it worth paying extra for?
ABC (All Back Contact) means that all the electrodes of the module are located on the back, without metallic strips on the front glass. This creates a double benefit: more active surface area captures light, and the temperature coefficient is only -0.26%/°C, meaning the panel loses less power on hot days compared to a typical TOPCon module. This is a real advantage, not just a marketing claim, for roofs with limited surface area or in locations with high summer sunlight.
Do AIKO Neostar 455W solar panels suitable for roofs with chimneys or trees nearby?
Yes. ABC architecture and N-type cells are better able to withstand partial shading than older PERC technology, as the current flow is more evenly distributed across the cell surface. In practice, this means a smaller drop in production when the shadow from a chimney, skylight, or branch falls on part of the module. However, the Neostar series will not replace an optimizer or microinverter in extremely shaded installations.
What are the dimensions and weight of the AIKO-A455-MAH54Db module, and does it fit a typical Polish pitched roof?
The panel measures 1757 × 1134 × 30 mm and weighs approximately 24.5 kg. It is a standard 54-cell (half-cut) format that easily fits on typical pitched roofs in Poland, both gable and four-pitched. The glass-glass (two 2.0 mm thick glass) construction slightly increases the weight compared to glass-film modules, so when installing on an older roof, it is advisable to check the roof's load-bearing capacity with an installer beforehand.
What differentiates the AIKO Neostar from the popular TOPCon panels available at a similar price?
The main difference lies in the cell architecture. TOPCon is an evolution of the traditional cell design with contacts on the front, while ABC moves all the contacts to the back, resulting in a higher module efficiency of 23.3% for the same surface area. Both types utilize N-type cells with low degradation, but AIKO Neostar achieves higher energy yield per square meter of roof area and better performance at high temperatures. ABC modules typically have a higher price, which is particularly advantageous where roof space is limited.
Is the AIKO Neostar AIKO-A-MAH54Db panel available in Poland, and is AIKO a reputable manufacturer?
Yes, modules from the Neostar series are available from Polish distributors of renewable energy systems (RES). AIKO Solar is a Chinese manufacturer, classified as Tier 1 by Bloomberg NEF, which indicates financial stability and confirmed production volume. The company is known for its focus solely on ABC technology and holds IEC and MCS certifications. However, it is advisable to compare offers from several suppliers before making a purchase, as prices in this segment can vary.
