This represents a significant advantage over standard TOPCon (~-0.30%/°C) and PERC (~-0.35%/°C) technologies, resulting in a demonstrably higher yield, especially during hot summer days. - **Shade resistance confirmed by TÜV.** - The TÜV NORD report confirms that ABC AIKO modules generate up to 30% more energy than a standard TOPCon module under full shading of a single cell. In installations with chimneys, antennas, or edge shading, Neostar 1S maintains a significantly better energy production compared to technologies with front-mounted contacts. - **Full Black without a mesh – architectural aesthetics** - The absence of metallic rails on the front (Back Contact) creates a uniformly black surface for the panel. Compared to competitors in the same price range (e.g., Lina Energy LEPV 132 Ultra Premium, which has a visible grid), the Neostar 1S is the preferred choice for architectural requirements and BIPV projects. - **30-year performance guarantee, degradation ≤0.35%/year** - The manufacturer guarantees ≥88.85% of the nominal power after 30 years, with an annual degradation of ≤0.35% (≤1% after 1 year). The comparable KDM Kingdom Solar KDM Series does not offer an equivalent 30-year linear warranty, making AIKO's offer more competitive in the long term. - **Tier 1 BNEF – bankability confirmed in 2026** - AIKO Solar is listed on the BNEF Tier 1 Module Manufacturers list (methodology updated on March 18, 2026), which guarantees access to project financing and minimizes the manufacturer's residual risk throughout the warranty period. ## Cons - **Product warranty is only 15 years.** - Neostar 1S offers a 15-year product warranty, while newer AIKO series (Neostar 2S+, 3S+) already have a 25-year warranty. For example, the Luxor ECO LINE N-TYPE TOPCon Non-Reflect panel from the peer segment also offers a 25-year product warranty. This represents a significant difference for investors calculating ROI over 15 years. - **Performance below that of the leading competitor in the segment** - The maximum efficiency of the Neostar 1S is 22.5%, while the Luxor ECO LINE N-TYPE TOPCon Non-Reflect achieves 22.86% at the same peak power of 440 Wp. On roofs with limited surface area, the difference of approximately 0.36% translates into a significantly smaller number of modules that can be installed for the same square meter budget. ## About this series The AIKO Neostar 1S series was designed for maximum energy yield on limited rooftop space - without compromising on aesthetics. Key here is the **N-Type ABC (all back contact) cell technology**, or rear-contact architecture, ensuring the module's front remains uniform and better utilizes light. This translates to high efficiency even under less-than-ideal conditions - elevated operating temperatures, transient overcast periods, and partial edge shading. Neostar 1S is also a **Full Black with no visible front grid lines**, genuinely facilitating the integration of the installation into modern architecture and meeting investors' requirements. An additional advantage is **low long-term degradation**, ensuring stable energy production for years and making the investment return more predictable. In residential and small commercial applications, you also benefit from **BOS cost optimization** - more power from fewer modules, simpler wiring and installation. Neostar 1S stands out where every square meter, appearance, and long-term reliability matter. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*Back Contact 400-450W\*\* modules - Power density of 222.8 W/m² matches the \*\*Back Contact 400-450W\*\* median - -0.26%/°C temperature coefficient (median: -0.29%/°C) - retains ~1% more power at high temperatures - #5100 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What is the ABC technology used in AIKO Neostar 1S panels, and why is it important? ABC (All Back Contact) is a cell architecture in which all electrical contacts are moved to the rear side. This results in a smooth front surface without metallic grids, which increases the light-absorbing surface area. In practice, this means a higher efficiency (up to 22.5%) compared to typical PERC or TOPCon modules of similar power, meaning more energy from each square meter of roof area. ### What warranty does the Aiko Neostar 1S panel manufacturer offer? AIKO offers a 15-year product warranty (for physical defects and workmanship) and a 30-year performance warranty. During the initial years, degradation does not exceed 1%, and then decreases to no more than 0.35% per year for the first 30 years of operation. This is one of the best degradation rates in the N-Type module class, which translates into more predictable returns on investment. ### Do the AIKO Neostar 1S Full Black panels look good on the roof, and do they suit modern architecture? Yes, the Neostar 1S series is exclusively available in a full black version with a single-tone black front surface, eliminating the visible metal mesh. The dark frame, black background of the cells, and the absence of silver rails make the modules blend seamlessly with the roof covering. This is a significant advantage for investors who prioritize aesthetics, as well as for properties subject to conservation requirements or guidelines from homeowners' associations. ### How well do the AIKO Neostar 1S solar panels perform under high temperatures and partial shading on the roof? The N-Type ABC technology is characterized by a low temperature coefficient, which means lower power losses on hot days compared to P-Type modules. Furthermore, the absence of front electrical contacts makes the cells less susceptible to hot spots at the edges, such as those caused by chimneys or dormer windows. The module operates in a temperature range of -40°C to +85°C and is certified for wind and snow loads up to 5400 Pa. ### How many Aiko Neostar 1S 440W solar panels do I need to install a 10 kWp solar system on a single-family home? With a power of 440 W per module for an installation with a total capacity of 10 kWp, you will need approximately 23 panels (22.7 units). Each module has dimensions of 1722 x 1134 x 30 mm and weighs approximately 24 kg, which means it occupies an area of around 43-45 m² and the total weight of the installation is approximately 550 kg. The high individual power of 440 W allows you to generate more energy on a smaller roof compared to typical 380-400 W modules. ### Is AIKO a reputable manufacturer, and are Neostar 1S panels available in Poland? AIKO Solar is a Chinese manufacturer classified as Tier 1 by Bloomberg NEF, specializing specifically in high-efficiency ABC modules. The Neostar 1S series is actively sold through authorized distributors in Poland and Europe. The Tier 1 status signifies, among other things, bankability, meaning acceptance by financial institutions that fund commercial installations, which facilitates obtaining a loan or lease for the investment. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/aiko-a-mah54mb-430-450w-neostar-1s-184-en-v5-4-3c2318befa1c.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, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, heavier, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, heavier, +2.0 pp | | [AIKO AIKO-A430-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a430-mah54mb) | 430 W | -0.3 pp | | [AIKO AIKO-A440-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a440-mah54mb) | 440 W | Very close match | | [AIKO AIKO-A445-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a445-mah54mb-1) | 445 W | +10 W, hotter, +0.5 pp | | [AIKO AIKO-A450-MAH54Db](https://comparepv.com/panel/shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a450-mah54db) | 450 W | +15 W, hotter, +0.7 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +20 W, heavier, +1.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, heavier, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, heavier, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, heavier, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, +2.2 pp | --- Source: https://comparepv.com/panel/aiko-aiko-a435-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.
