In the 54-cell Full Black category, it is one of the highest commercially available results in 2025. - **Temperature coefficient: -0.26%/°C** - The ABC technology eliminates front metallization and reduces resistive losses, resulting in a Pmax TC of -0.26%/°C. Standard PERC modules achieve -0.35 to -0.38%/°C – in a Polish climate with summer temperatures of 60°C on an Aiko module, it loses 9.1% of power, while a PERC module loses approximately 13%, which translates into a real saving of several additional kWh per year. - **A degradation rate of 0.35% per year after the first year.** - The declared linear degradation rate is less than 1% in the first year, and ≤0.35%/year in years 2-30, guaranteeing ≥88.85% of the nominal power after 30 years. Typical TOPCon modules from competitors (e.g., JA Solar, Trina) declare 84.8–87% after 25 years, which, with a 30-year horizon, makes Neostar 2S significantly more advantageous. - **30-year power output warranty** - The product warranty is 25 years, and the power warranty is 30 years. Most models in this segment (Recom Lynx, Sunlike SKT96D) offer a 25-year power warranty. The longer warranty period reduces investment risk and simplifies the financing of bankable projects. - **N-type ABC Full Black – combining aesthetics and resistance to mismatch** - Moving all connections to the rear of the cells creates a uniform black front without visible rails, which is highly valued in premium installations. At the same time, the ABC architecture naturally minimizes losses due to mismatched cells and performs better in partially shaded conditions than traditional PERC panels, as confirmed by an independent review by SolarQuotes (2025). ## Cons - **Premium pricing above the TOPCon segment** - According to market data from 2025 (SolarChoice AU), installing a 13 kWp system with AIKO ABC modules costs approximately $700 more than a system with comparable power output using TOPCon modules (JinKo, LonGi, Canadian). For a typical 6-10 kWp residential system, the overpayment could range from $300 to $500, without the additional disadvantage of higher costs when there are no issues with space or aesthetics. - **Lack of bifaciality** - The AIKO-A-MAH54Mb series is monofacial (is\_bifacial: false). Alternative N-type BC technologies with bifacial back glass typically offer an additional 5–15% gain due to reflected albedo (e.g., a light-colored floor, gravel, or snow). The Neostar 2S does not utilize this potential, which could be a disadvantage in ground-mounted or roof-mounted installations with a light-colored membrane. ## About this series The AIKO Neostar 2S (AIKO-A-MAH54Mb) series was designed for maximum yield from every square meter of roof - especially where aesthetics and reliable performance in real conditions matter. Central to this is the **N-type ABC (All Back Contact)** technology, which moves the connections to the rear of the cell. The result is a uniform black front surface, free from visible ribbons, while simultaneously optimizing light capture on the active surface. (\[solarvie.at\](https://www.solarvie.at/en-eu/products/aiko-neostar-2s-aiko-a460-mah54mb-abc-technologie?utm\_source=openai)) In practice, the Neostar 2S strongly defends where other modules falter - under partial shading and panel mismatch conditions. The built-in **cell-level optimization** helps minimize losses from mismatch, translating to more predictable energy production throughout the day.

The series also offers **high resistance to micro-cracking** and long warranties, genuinely reducing long-term risks.

ABC (All Back Contact) is a design in which all electrical connections for the solar cells are located on the back of the panel. In practice, this means that there are no visible busbars on the front surface, which increases the light-absorbing area and results in an efficiency of up to 23.6%. For installers, this also represents a real energy saving compared to traditional PERC or TOPCon technologies, on the same roof area. ### What is the warranty on Aiko Neostar 2S panels? The Neostar 2S series is covered by a 25-year product warranty and a 30-year linear performance warranty. The manufacturer guarantees that after 30 years of operation, the module will maintain at least 88.85% of its nominal power. The annual degradation rate after the first year is only 0.35%, placing this series among the most durable modules available on the market. ### Do AIKO Neostar 2S solar panels perform well on hot days or at high temperatures? Yes, the temperature coefficient of power for the Neostar 2S module is only -0.26%/°C, which is one of the best results in the premium module class. For comparison, a typical PERC module loses approximately -0.35%/°C. In practice, the Neostar 2S module produces significantly more energy on hot summer days than an average panel, which is particularly important for rooftop installations with good solar exposure. ### What are the dimensions and weight of the AIKO Neostar 2S panel — and is it difficult to install? The panel measures 1757 × 1134 × 30 mm and weighs 21.5 kg. These are standard dimensions for a 54-cell module, compatible with typical mounting systems used on pitched and flat roofs. The weight is within the typical market range, so two people can easily move and install it without specialized equipment. ### Will the AIKO Neostar 2S perform adequately on a roof with partial shading, such as that caused by a chimney or dormer window? The Neostar 2S series features built-in cell-level optimization that reduces losses due to mismatching under partial shading. The N-type ABC technology with front-terminalless cells also minimizes the risk of hotspot formation. This is a good option for roofs with chimneys, antennas, or skylights, although in cases of strong and consistent shading, it may be worthwhile to consider additional power optimizers. ### Who is the AIKO Neostar 2S designed for – is it primarily for large-scale installations? No, the Neostar 2S (up to 470 W) is primarily designed for residential installations where maximizing power output on a limited roof area is the priority. Its full black finish and lack of visible mounting rails make it a good fit for modern or dark roofing materials. It is particularly advantageous in situations where roof space is limited, and the investor wants a high-quality module with a long, guaranteed warranty. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/neostar-2s-188-aiko-a-mah54mb-440-470w-1757x1134x30mm-ds-en-360aa83fa979.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +40 W, cooler, +1.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +25 W, +1.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +35 W, cooler, +1.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +20 W, +0.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +30 W, cooler, +0.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +30 W, +0.9 pp | | [AIKO AIKO-A435-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a435-mah54tm) | 435 W | Lighter, -1.8 pp, -5 yr warranty | | [AIKO AIKO-A440-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a440-mah54tm) | 440 W | Lighter, -1.6 pp, -5 yr warranty | | [AIKO AIKO-A445-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a445-mah54tm) | 445 W | Lighter, -1.3 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a450-mah54tm) | 450 W | Lighter, -1.1 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a450-mah54mw) | 450 W | -20 W, -1.0 pp | | [AIKO AIKO-A455-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a455-mah54tm) | 455 W | Lighter, -0.8 pp, -5 yr warranty | | [AIKO AIKO-A455-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a455-mah54mw) | 455 W | -15 W, -0.8 pp | | [AIKO AIKO-A460-MCE54Db](https://comparepv.com/panel/aiko-aiko-a460-mce54db) | 460 W | -10 W, heavier, -0.6 pp | | [AIKO AIKO-A460-MAH54Db](https://comparepv.com/panel/aiko-solar-aiko-a460-mah54db) | 460 W | -10 W, heavier, -0.5 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a470-mah54mb Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
