The maximum efficiency of this series reaches 23.6% – slightly higher than direct competitors (Recom Lynx 23.52%, Sunlike Solar SKT 23.52%) at the same power rating of 470 Wp. - **The lowest degradation rate in this segment – 0.35%/year** - The guaranteed annual degradation of ≤0.35% (years 2-30) is better than the typical 0.40%/year for N-type TOPCon modules. In practice, the module retains ≥88.85% of its power after 30 years, which, for a 10 kWp installation, translates to a real increase in cumulative energy generation of approximately 1.5–2 MWh over its entire lifespan compared to 25-year TOPCon products. - **30-year power guarantee** - The manufacturer guarantees performance for 30 years, with a degradation rate of ≤1% in the first year and ≤0.35% per year thereafter, while comparable products (Recom Lynx, Sunlike Solar) typically offer a 25-year performance guarantee. The longer warranty period directly improves the IRR (Internal Rate of Return) of the project and facilitates bank financing. - **Temperature coefficient: -0.29%/°C** - The Pmax tc value of -0.29%/°C is more favorable than the typical -0.35%/°C for PERC modules and -0.30%/°C for average TOPCon modules. At an operating temperature of 70°C (typical summer temperatures in Poland), the difference in terms of thermal losses compared to PERC is approximately 1.7%, which translates to a real increase in output during August and July. - **BNEF Tier 1, Q1 2026 – Fully bankable** - AIKO is listed on the BloombergNEF Tier 1 PV Module Manufacturers list for Q1 2026 (confirmed in Q3 2025 and Q1 2026). This status indicates acceptance by banks that finance commercial installations and reduces counterparty risk in long-term PPA or leasing agreements. ## Cons - **Lack of bidirectional functionality** - Despite its dual-glass (glass-glass) construction, the module is not bifacial (is\_bifacial: false), which means that energy cannot be generated from the rear surface. For carport and flat-roof applications with a clear membrane, as the manufacturer specifies in the product description, bifacial versions can generate an additional 5–15% of energy per year. - **Higher weight in the dual-glass version** - The glass-to-glass construction increases the weight of the module to approximately 24 kg (1757 x 1134 mm), compared to approximately 21 kg for the glass-to-film equivalent. In installations on older roofs with dense configurations, it is necessary to verify the structural load-bearing capacity, which could result in additional costs for a structural analysis or reinforcement. ## About this series The AIKO Neostar 2S+ Dual-Glass (AIKO-A-MAH54Db) is designed for investors seeking to extract maximum energy from limited rooftop space while simultaneously minimizing risks typical of long-term operation. Its key advantage is the **N-type ABC (All-Back Contact)** technology - free from front busbars, which enhances light utilization and provides a uniform, elegant module appearance. In practice, this also ensures reliable performance under real-world conditions, where installations don't always have ideal sunlight exposure. The module's **dual-glass** construction increases resistance to micro-cracks, moisture, and material fatigue, translating to stable energy production for years. The applied **optimized performance under partial shading** helps reduce losses when shade from chimneys, trees, or dirt covers only part of the panel. Additionally, **superior performance in high temperatures** supports efficiency during summer months. This is an excellent choice for premium homes, complex roof geometries, carports, and projects where durability, aesthetics, and predictable yield are key priorities. ## Notable figures - At 23.1% efficiency, this panel is on par with typical \*\*Back Contact 450-500W\*\* modules - 230.9 W/m² power density is 4.3 W/m² below \*\*Back Contact 450-500W\*\* median (235.2 W/m²) - requires larger installation area - At -0.26%/°C, hot weather performance is typical for \*\*Back Contact 450-500W\*\* panels - At 24.5 kg, weight matches the \*\*Back Contact 450-500W\*\* median - Ranked #1570 out of 14005 panels for efficiency in the database ## Questions ### What is the ABC technology used in AIKO Neostar 2S+ panels, and how does it differ from standard solar cells? The ABC (All Back Contact) technology means that all the electrical connections of the solar cell are located exclusively on its back side – the front surface is completely free of metal collecting strips. This allows for greater surface area to absorb sunlight, resulting in a module efficiency of up to 23.6%, which is difficult to achieve with traditional PERC or TOPCon technologies. An additional benefit is a uniform and aesthetically pleasing appearance, with no visible lines on the front surface. ### What is the warranty for Aiko Neostar 2S solar panels? The manufacturer provides a 25-year product warranty covering physical and material defects, as well as a 30-year linear warranty on power output. After 30 years, the module should maintain at least 88.85% of its original performance, with a degradation rate of only 0.35% per year – after the first year of operation. These are among the most favorable warranty terms currently available in the photovoltaic panel market. ### How well do the Aiko Neostar 2S+ panels perform in the summer with high temperatures on the roof? The Neostar 2S+ series has a power temperature coefficient of -0.26%/°C, which is one of the lowest values among available modules. This means that it loses less power compared to standard PERC panels (-0.35%/°C) when the roof temperature exceeds 60°C in summer. In Polish conditions, where roof surface temperatures exceed 60°C in the summer, this difference translates into a significantly higher annual energy yield. ### Is the Aiko Neostar 2S+ dual-glass 470 Wp panel suitable for a pitched roof or carport? Yes, the 1757 x 1134 x 30 mm module, weighing 24.5 kg, is suitable for typical roof and carport structures. The dual-glass construction can withstand snow and wind loads of up to 5400 Pa from the front, meeting the requirements of the Polish climate zone. In carports, the mechanical durability of the double glass and the aesthetically pleasing appearance of the module, without visible rails on the front, are particularly appreciated. ### What is the dual-glass construction in the AIKO Neostar 2S+ series, and why is it a better choice than the version with a film? "Dual-glass" refers to replacing the backsheet (protective film) with a second glass – in the Neostar 2S+, these are two layers of 2mm thick tempered glass each. This design reduces moisture ingress, minimizes the risk of micro-cracks in the cells, and extends the lifespan of the module in harsh environments, such as near the sea or on agricultural sites. This translates to lower power degradation over the entire 30-year warranty period. ### Are Aiko Neostar 2S+ solar panels available in Poland, and is Aiko a reputable manufacturer? Yes, the AIKO Neostar 2S+ (AIKO-A-MAH54Db) modules from the AIKO series are currently available from distributors in Poland and are not being discontinued. AIKO Solar has a Tier 1 manufacturer status, which confirms its financial credibility and ability to fulfill long-term warranty obligations. The company specializes exclusively in ABC technology and is considered a leader in this technology on the global photovoltaic market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/neostar-2s-plus-188-aiko-a-mah54db-440-470w-1757x1134x30mm-d-ff3a18e59e43.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +1.6 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, lighter, +1.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +1.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, lighter, +1.4 pp | | [AIKO AIKO-A435-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a435-mah54tm) | 435 W | 16 kg lighter, -1.3 pp, -5 yr warranty | | [AIKO AIKO-A440-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a440-mah54tm) | 440 W | 16 kg lighter, -1.1 pp, -5 yr warranty | | [AIKO AIKO-A445-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a445-mah54tm) | 445 W | 16 kg lighter, -0.8 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a450-mah54tm) | 450 W | 16 kg lighter, -0.6 pp, -5 yr warranty | | [AIKO AIKO-A450-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a450-mah54mw) | 450 W | -10 W, lighter, -0.5 pp | | [AIKO AIKO-A455-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a455-mah54tm) | 455 W | 16 kg lighter, -0.3 pp, -5 yr warranty | | [AIKO AIKO-A455-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a455-mah54mw) | 455 W | Lighter, -0.3 pp | | [AIKO AIKO-A460-MCE54Db](https://comparepv.com/panel/aiko-aiko-a460-mce54db) | 460 W | Very close match | --- Source: https://comparepv.com/panel/aiko-solar-aiko-a460-mah54db 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.
