When a 65°C module is heated in a typical Polish summer, the 3S54 series loses approximately 10.4% of its power, compared to approximately 16% for standard panels – resulting in a higher power output during months with the most sunlight. - **ABC Technology – eliminates optical losses from the front** - N-type ABC (All Back Contact) cells move all electrical contacts to the back of the cell, eliminating shading caused by busbars and ribbons. This allows for maximum efficiency of up to 24.3% and maximizes the capture of diffuse light, which is particularly important in the cloudy climate of Poland. - **Exceptionally low long-term degradation** - The manufacturer guarantees a degradation rate of ≤1% in the first year and ≤0.35%/year from year 2 to 30, resulting in ≥88.85% of the nominal power after 30 years. Typical Tier-1 PERC/TOPCon panels (e.g., Jinko, Trina) offer a degradation rate of 0.40%/year and 84.8% after 25 years – the 3S54 series offers a more realistic production forecast throughout the entire lifespan of the installation. - **30-year power guarantee** - The linear warranty on power output extends for 30 years (along with a 25-year product warranty), which exceeds the standard market warranty of 25 years. For banks and insurers, the longer warranty offered by Tier-1 manufacturers reduces project risk and improves financing parameters. - **Premium aesthetics: a fully black design without busbars.** - The absence of metallic busbars on the front surface and the dark glass create a uniform black appearance, which is highly valued in premium roof installations and areas subject to aesthetic requirements. Only a few manufacturers achieve a similar visual effect – for example, Gokin GK-5-54HG – but AIKO, as a Tier-1 brand, offers superior reliability. ## Cons - **Lack of bifaciality – exclusively mono-glass** - The 3S54 series is a single-sided panel (is\_bifacial: false), which means it does not generate additional power from reflected light from the ground. In installations on light, flat roofs or with white membranes, bifacial versions can generate 5–12% more energy per year without any additional surface area cost. - **This series does not stand out from the rest of the ABC market in terms of performance.** - The maximum efficiency of 24.3% is identical to that of the Gokin GK-5-54HG and GK-5-54HGb (comparable products in the same power segment of 485 Wp). Any price or availability advantage offered by AIKO must be verified individually – the efficiency itself is not a differentiating factor. ## About this series The AIKO Neostar 3S54 (Mono-glass Module) is designed to achieve maximum yield from limited rooftop space, without compromising on aesthetics or reliability. Its key feature is the **N-type ABC (All Back Contact)** cells- with contacts moved to the rear, minimizing optical losses and maximizing light utilization under real operating conditions. In practice, this means higher energy output where every square meter counts. A major advantage is **cell-level optimization for partial shading**, which helps mitigate production losses caused by factors like chimneys, antennas, dirt, or tree shadows. Additionally, the modules maintain a more stable power output in hot weather thanks to their **favorable temperature coefficient**, which is particularly important on heated rooftops during summer. This is an excellent choice for investors seeking to expand installations in limited spaces, as well as for premium homes where a **uniform, all-black appearance without visible busbars** matters. Compared to many competitor panels, the 3S54 series places greater emphasis on real-world shading resistance, aesthetics, and long-term predictable performance. ## Notable figures - Efficiency of 23.8% matches the \*\*Back Contact 450-500W\*\* median - At 237.7 W/m² power density, roof space requirements are typical for \*\*Back Contact 450-500W\*\* panels - Temperature coefficient of -0.26%/°C matches the \*\*Back Contact 450-500W\*\* median - Weight of 21.0 kg (2.5 kg below \*\*Back Contact 450-500W\*\* median of 23.5 kg) allows easier transport and roof mounting - In the top 3% for efficiency among all Back Contact panels ## Questions ### What is the ABC technology used in AIKO Neostar 3S54 panels, and why is it important? ABC (All Back Contact) means that all the electrical contacts of the solar cells are located on the back of the module. This eliminates visible junction strips on the front surface of the panel, which would reflect or obscure light. In practice, ABC-type N-type cells convert solar radiation more efficiently into electricity, resulting in higher efficiency and greater energy yield from the same roof area compared to standard PERC modules. ### What are the dimensions and weight of the AIKO Neostar 3S54 panel, and will it fit on a typical pitched roof? The panel has dimensions of 1762 × 1134 × 30 mm and weighs approximately 21 kg. This is a standard 54-cell format that is suitable for typical mounting structures used on pitched roofs in Poland. The weight allows for convenient transport and installation by two installers. However, it is advisable to check the roof's load-bearing capacity and the spacing between rafters before purchasing, in order to select the appropriate mounting system. ### How well do the Aiko Neostar 3S54 solar panels perform with partial shading caused by a chimney or antennas? The 3S54 series employs optimization at the individual cell level, which minimizes production losses in situations with partial shading. When only part of the module is shaded, the remaining cells operate without interruption. This is an advantage over older technologies, where shading of a single cell significantly reduced the output of the entire string. In cases of heavy shading, it may be worthwhile to consider additional power optimizers or microinverters. ### What is the warranty period for the Aiko Neostar 3S54 panel, and exactly what does it cover? AIKO offers a 25-year product warranty for material and workmanship defects, as well as a 30-year linear power warranty. The power warranty terms specify a maximum of 1% degradation in the first year of operation and no more than 0.35% per year in subsequent years. This means that after 30 years, the panel should maintain at least approximately 87.4% of its nominal power. AIKO is a Tier 1 manufacturer, which indicates the financial stability of the guarantor. ### Are the AIKO Neostar 3S54 series of solar panels suitable for premium homes with a requirement for a fully black roof? Yes, Neostar 3S54 modules are available in a full black version with a black frame and a uniformly black surface without visible busbars. The ABC technology eliminates the silver strips on the front glass, which are characteristic of traditional panels. This results in a uniform and aesthetically pleasing roof appearance, which is increasingly chosen by investors building energy-efficient or premium homes. ### How does the AIKO Neostar 3S54 485W solar panel perform in high temperatures during the summer months? The Neostar 3S54 module features a favorable temperature coefficient of power of -0.26%/°C, which is better than typical PERC panels with a value of approximately -0.35%/°C. In practice, this means that when the roof is heated in summer and the cell temperature reaches 65°C, the panel loses less power than its competitors. For installations on well-sunlit south-facing roofs, this represents a real difference in summer energy yield. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/neostar-3s54-aiko-a-mce54mb-460w-485w-8fa2a595eff0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +35 W, heavier, +1.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +20 W, +1.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +30 W, heavier, +0.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +15 W, +0.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +25 W, heavier, +0.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +25 W, +0.7 pp | | [AIKO AIKO-A435-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a435-mah54tm) | 435 W | Lighter, -2.0 pp, -5 yr warranty | | [AIKO AIKO-A440-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a440-mah54tm) | 440 W | Lighter, -1.8 pp, -5 yr warranty | | [AIKO AIKO-A445-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a445-mah54tm) | 445 W | Lighter, -1.5 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a450-mah54tm) | 450 W | Lighter, -1.3 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a450-mah54mw) | 450 W | -25 W, -1.2 pp | | [AIKO AIKO-A455-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a455-mah54tm) | 455 W | Lighter, -1.0 pp, -5 yr warranty | | [AIKO AIKO-A455-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a455-mah54mw) | 455 W | -20 W, -1.0 pp | | [AIKO AIKO-A460-MCE54Db](https://comparepv.com/panel/aiko-aiko-a460-mce54db) | 460 W | -15 W, heavier, -0.8 pp | | [AIKO AIKO-A460-MAH54Db](https://comparepv.com/panel/aiko-solar-aiko-a460-mah54db) | 460 W | -15 W, heavier, -0.7 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a475-mce54mb 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.
