This difference of 0.56–1.93 p.p. translates to a real increase of 5–8% in energy production from the same roof area, without the need to increase the number of modules. - **Temperature coefficient: -0.26%/°C** - Among the lowest values in the segment – standard TOPCon technologies from competitors exhibit -0.30 to -0.35%/°C, while older PERC technologies can reach -0.40%/°C. In typical Polish summer days (module temperature of 65–70°C, i.e., ~40°C above STC), the thermal losses are 0.5–1.4% lower than those of comparable models, which directly translates into higher energy yield during the peak season. - **Degradation ≤0.35%/year, 30-year linear warranty** - AIKO guarantees a power drop of ≤1% in the first year and ≤0.35% per year for the next 29 years, which means maintaining ≥88.85% power output after 30 years. Peer comparisons with Seraphim and Resun offer 30-year guarantees, but at higher degradation rates; the linear guarantee (rather than a gradual one) eliminates ambiguity in performance-related claims. - **N-type ABC (all-back-contact) architecture** - Moving all electrical contacts to the back of the cell eliminates self-shading of the metallic fingers, increasing the active area for photoactivity. The ABC technology exhibits a lower light-induced degradation (LID) rate than P-type materials, and its improved performance under diffuse sunlight (cloudy conditions, partial shading) significantly enhances performance in Polish weather conditions for a large portion of the year. - **Bankable Tier-1, industry award 2025** - AIKO is listed on BNEF's Tier-1 bankable list, which allows for the financing of C&I projects with bank credit without requiring additional collateral from the manufacturer. In 2025, the Neostar series won first place in the SolarQuotes Installers' Choice Awards, confirming the positive feedback from installers based on real-world performance, rather than just laboratory testing. ## Cons - **Product warranty is only 15 years.** - The Neostar 3N54 mono-glass series comes with a 15-year warranty for manufacturing defects, while the current Tier-1 standard (JA Solar, Jinko, LONGi, Canadian Solar) offers a 25-year warranty. Considering a 30-year lifespan, this means that for half of the installation's life, protection against manufacturing defects is solely the responsibility of the user – a significant risk for projects with long-term financing. - **Lack of bifaciality – mono-glass** - The mono-glass module does not generate energy from the back. In installations on light surfaces (white TPO membrane, light gravel, snow), bifacial modules from competing products in the same power segment generate an additional 5-15% of energy through reflected albedo – a feature that Neostar 3N54 does not structurally offer. - **Price premium for technology ABC** - ABC modules are typically 10–15% more expensive than mainstream TOPCon modules with similar rated power. For a typical 10 kWp (approximately 20 panels) installation, the difference is estimated to be around 1,000–2,500 zł compared to comparable Seraphim YUKON N or Resun RS8K-M modules. The higher cost of premium modules may be difficult to justify with a short payback period or a limited budget. ## About this series The AIKO Neostar 3N54 (mono-glass) series was designed to maximize energy output from the same rooftop surface - without compromising on aesthetics or reliability, typical trade-offs. Its key is ****ABC N-type (all-back-contact) technology****, meaning the electrical connections are moved to the rear of the cell. In practice, this means more active surface area for light absorption, better performance in diffuse lighting, and lower resistive losses - leading to a more stable yield in real-world conditions. The Neostar 3N54 stands out with ****high resistance to partial shading****, which is beneficial in areas with chimneys, window frames, trees, or antennas. Additionally, ****favorable thermal stability**** supports energy production during summer, when standard modules often "breathe" their efficiency. This is the right choice for premium home installations and C&I projects, where ****high yield per square meter****, long-term reliability, and guaranteed performance parameters matter. Compared to many competitive modules, the advantage stems not from marketing but from the cell architecture and a consistent focus on real-world yield and system safety. ## 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 - At 21.0 kg, this panel is 2.5 kg lighter than \*\*Back Contact 450-500W\*\* median (23.5 kg) - easier handling during installation - #433 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What is the warranty on Aiko Neostar 3N54 panels, and is the power degradation linear? The AIKO Neostar 3N54 series is covered by a 15-year product warranty and a 30-year linear power warranty. Degradation is no more than 1% in the first year of operation, and no more than 0.35% per year thereafter. This is one of the best degradation rates available for premium-class modules on the market. ### What is the ABC technology used in AIKO Neostar 3N54 panels, and why should you choose it? ABC (All-Back-Contact) is a cell architecture in which all electrical connections are moved to the back of the panel. This allows the front surface to absorb more light, resulting in efficiencies of up to 24.8% in the Neostar 3N54 series. In practice, this means more energy from the same square meter of roof compared to typical PERC or topcon modules. ### Do Aiko Neostar 3N54 solar panels perform well in partially shaded conditions, such as those caused by a chimney or trees? Yes. The N-type ABC technology is characterized by high resistance to partial shading, as each cell generates electricity independently without the dominant influence of so-called "hotspots". The Neostar 3N54 series will perform better on roofs with chimneys, skylights, antennas, or nearby vegetation compared to standard PERC modules with busbars on the front side. ### How do the Aiko Neostar 3N54 panels perform in the summer when exposed to high temperatures? The Neostar 3N54 modules have a favorable temperature coefficient of power, which is -0.26%/°C. This means that they experience a smaller decrease in energy production on hot days compared to typical modules (typically -0.35%/°C or higher). In the summer, at a panel temperature of around 65°C, this difference can translate into a few percentage points higher annual yield. ### Which types of installations are suitable for Aiko Neostar 3N54 modules – single-family homes or larger projects? The Neostar 3N54 series, with a power output ranging from 470 W to 495 W, is suitable for both premium residential installations (higher energy yield from a limited roof area) and commercial and industrial C&I projects. The manufacturer is classified as Tier 1, which facilitates project financing and provides assurance of a stable supply chain. ### Is the Aiko Neostar 3N54 495W solar panel a bifacial panel? No, the Neostar 3N54 model in its mono-glass version is not a bifacial panel. It is a single-glass module, which simplifies installation and reduces weight compared to the dual-glass version. If you are looking for a bifacial panel from this technology family, you might consider other AICO series available in a dual-glass version. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/neostar-3n54-aiko-a-mce54mw-470w-495w-63788c431933.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-mce54mw 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.
