In the Polish climate (with surface temperatures of 50–60°C in summer), this translates to a significantly higher power output on hot days compared to most Tier-1 panels in this power segment. - **Ultra-lightweight: 8.6 kg per module** - The 460W module weighs only 8.6 kg, while standard panels with similar power (e.g., Risen RSM96-11-460BNDG) typically weigh around 20-23 kg. This allows for installation on roofs with limited load-bearing capacity and significantly reduces installation costs and time (lighter sub-structures, one-person installation). - **Exceptionally low long-term degradation** - N-type ABC cells exhibit an annual degradation rate of approximately 1% in year 1 and ~0.35%/year in years 2–25, which is approximately 1.2 percentage points better than comparable TOPCon modules after 25 years (data from AIKO, confirmed by independent analysis by TaiyangNews 2024). The power warranty covers ≥90.6% of the nominal power after 25 years, which exceeds the typical 84.8–87% for 25-year warranty TOPCon models on the market. - **Absence of electrodes on the front – increased light absorption** - Placing all electrical contacts on the back of the cell eliminates shading caused by bus bars and metallic fingers, which in traditional modules absorb 4–6% of incident light. This results in a module efficiency of up to 23% – on par with direct competitors (Risen 23%, SunKean 23.02%) while simultaneously eliminating LID (Light-Induced Degradation), a characteristic issue for P-type silicon modules. - **Certified resistance to microcracks and PID (Power Inverter Disturbance)** - The manufacturer subjects the modules to tests that go beyond IEC standards, with a particular focus on resistance to acid corrosion and PID (Potential-Induced Degradation). As a Tier-1 supplier listed on the BNEF (Bloomberg New Energy Finance) list, the manufacturer guarantees access to project financing and a stable supply chain. ## Cons - **Product warranty: 12 years below the standard** - The Nebular 2P series offers a 12-year product warranty, while many Tier-1 manufacturers in the premium N-type segment (including Risen, Jinko, and LONGi) have increased their warranties to 15 years since 2023. For commercial installations financed by banks, this could be a contractual risk factor. - **Designed for single-sided use only – no reflection** - The series is not bifacial (is\_bifacial: false), which eliminates the possibility of obtaining an additional 5-15% of energy from the ground's albedo. In ground-mounted or rooftop installations (e.g., gravel, metal), bifacial alternatives in a similar price range (e.g., those from Risen or SunKean) can generate significantly higher annual yields. ## About this series AIKO Nebular 2P (Mono-Facial Module 430W-460W) was designed for maximum yield per square meter, without complicating the installation project. Its key feature is the use of **n-type ABC (All Back Contact) cells**, where the conductive elements are placed on the back of the cell - this allows the front of the module to better utilize light while maintaining an elegant, uniform appearance. In practice, this translates to **higher efficiency and greater power output from the same surface area**, which is particularly important for rooftops with limited space. The Nebular 2P also focuses on **optimization for partial shading**, helping maintain production when shade appears locally (e.g., from a chimney, antenna, or tree). Additionally, the construction is designed for **resistance to microcracking**, supporting stable parameters over time. This is an excellent choice for residential and commercial rooftop installations where high yield, aesthetics, and reliable performance under real-world conditions are key. ## Notable figures - Efficiency of 21.8% matches the \*\*Back Contact 400-450W\*\* median - At 217.7 W/m², this panel generates 5.0 W/m² less per unit area than \*\*Back Contact 400-450W\*\* median (222.7 W/m²) - At -0.26%/°C (vs median -0.29%/°C), loses ~1% less power in hot conditions - Weight of 8.6 kg (12.2 kg below \*\*Back Contact 400-450W\*\* median of 20.8 kg) allows easier transport and roof mounting - In the top 50% for efficiency among all Back Contact panels ## Questions ### What is the ABC technology used in Aiko Nebular 2P panels, and does it actually make a difference? ABC (All Back Contact) means that all the conductive components of the module are located on the back, rather than on the front surface. This ensures that no metallic pathways obstruct the light-collecting surface, allowing the Aiko Nebular 2P series to achieve a module efficiency of approximately 22.5%. This is significantly higher than typical PERC or TOPCon panels of similar size, resulting in a noticeably higher power output from the same roof area. ### What is the weight of the AIKO Nebular 2P panel, and is it possible to mount it on a lightweight roof or garage? The individual AIKO Nebular 2P module weighs only 8.6 kg with dimensions of 1762 × 1134 × 30 mm. This is approximately 12–13 kg less than conventional glass panels with similar power. This makes the series suitable for roofs with limited load-bearing capacity, such as halls with light trapezoidal steel, sheds, garages, or terrace canopies, where traditional modules would be too heavy. ### What is the warranty on Aiko Nebular 2P panels, and what does it cover? AIKO offers a 12-year product warranty on the Nebular 2P series, which covers defects and material damage for this period. In addition, a 25-year linear warranty on power is provided – the manufacturer guarantees that degradation will not exceed 1% in the first year, and a maximum of 0.35% per year thereafter. After 25 years, the panel should retain at least approximately 87.4% of its nominal power. ### Will the AIKO Nebular 2P perform adequately on a roof that is partially shaded by a chimney or antenna? Yes, the Nebular 2P series is designed for better performance under partial shading. The n-type ABC cell technology, combined with an appropriate electrical configuration of the module, minimizes energy losses when only a portion of the panel is shaded. While this does not eliminate losses entirely, in practice, the installation loses significantly less energy compared to traditional PERC modules without optimizers. ### How does the AIKO Nebular 2P perform in the summer months at high temperatures? The temperature coefficient of power for the Nebular 2P series is -0.26%/°C, which is one of the lowest figures in the class of polycrystalline and monocrystalline panels. For comparison, a typical PERC panel loses approximately -0.35%/°C. This means that on a hot summer day (e.g., 55°C on the module's surface), the Nebular 2P loses a smaller percentage of power compared to the average competitor, resulting in higher annual energy yield in the Polish climate. ### Is the AIKO Nebular 2P a bifacial panel, and is it worth paying extra for a bifacial version? No, the AIKO Nebular 2P series is a mono-facial module – it collects energy only from the front. This is not a disadvantage, but a deliberate design choice: the ABC technology on the back of the module occupies the rear surface with electrical contacts. In rooftop installations, where reflections from the ground are minimal, bifacial modules rarely provide a real gain of more than 2–5%, so the Nebular 2P remains a very competitive option due to its high efficiency of 22.5%. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/nebular-2p-aiko-a-mah54tm-430-460w-1762x1134x30mm-dsdr-en-24-fab05dd40282.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, heavier, +2.5 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, heavier, +2.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, heavier, +2.5 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, heavier, +2.5 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, 16 kg heavier, +2.5 pp | | [AIKO AIKO-A440-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a440-mah54tm) | 440 W | Very close match | | [AIKO AIKO-A445-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a445-mah54tm) | 445 W | +10 W, +0.5 pp | | [AIKO AIKO-A450-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a450-mah54tm) | 450 W | +15 W, +0.7 pp | | [AIKO AIKO-A450-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a450-mah54mw) | 450 W | Heavier, +0.8 pp, +5 yr warranty | | [AIKO AIKO-A455-MAH54Tm](https://comparepv.com/panel/aiko-solar-aiko-a455-mah54tm) | 455 W | +20 W, +1.0 pp | | [AIKO AIKO-A455-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a455-mah54mw) | 455 W | Heavier, +1.0 pp, +5 yr warranty | | [AIKO AIKO-A460-MCE54Db](https://comparepv.com/panel/aiko-aiko-a460-mce54db) | 460 W | 16 kg heavier, +1.2 pp, +5 yr warranty | | [AIKO AIKO-A460-MAH54Db](https://comparepv.com/panel/aiko-solar-aiko-a460-mah54db) | 460 W | 16 kg heavier, +1.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, heavier, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, heavier, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, heavier, +2.9 pp | --- Source: https://comparepv.com/panel/aiko-solar-aiko-a435-mah54tm Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
