The ABC technology eliminates shading of cells caused by the front collective rails, which is a physical advantage that cannot be achieved by competing LONGi Hi-MO 9 and Canadian Solar TOPBiHiKu6 modules based on TOPCon. - **Temperature coefficient: -0.26%/°C** - This is the lowest temperature coefficient among mass-produced modules – approximately 13% better than the standard TOPCon (-0.30%/°C) and approximately 24% better than PERC (-0.34%/°C). At typical operating temperatures for modules in Poland (55–65°C during the summer peak), this translates to a real increase of approximately 1.5–2% in energy generation during the summer months compared to the competition (TOPCon). - **Degradation ≤0.35%/year – better than TOPCon** - The annual degradation rate of ≤0.35% (LID below 1% in the first year) outperforms standard TOPCon (≤0.40%/year) and PERC (≤0.45%/year). Over a 30-year linear power guarantee, this translates to a cumulative loss of approximately 1.5% lower than typical TOPCon, resulting in approximately 450-600 kWh more energy production over the entire lifespan, particularly in a 10 kWp installation. - **BNEF Tier 1 bankable (Q1 2026)** - AIKO holds Tier 1 BloombergNEF status, confirmed for Q1 2026 – an award given to approximately 2% of the 17,000 solar manufacturers globally. This status is a standard requirement for obtaining bank financing for PV projects and protects investors from the risk of the manufacturer's bankruptcy within the 30-year warranty period. - **Elimination of hot spots, shade resistance** - ABC architecture moves all electrical contacts to the rear of the cell, physically preventing the formation of hot spots. TÜV Nord confirmed a 30% higher energy yield compared to traditional technology under full shading of a single cell – a key advantage in installations with chimneys, skylights, or nearby vegetation. ## Cons - **The product warranty is only 15 years.** - The Stellar Mono-Glass series offers a 15-year product warranty (on materials and workmanship), while AIKO for other series and the market standard tier-1 (LONGi Hi-MO 9, Canadian Solar TOPBiHiKu6) offers a 25-year warranty. The 10-year difference in warranty coverage translates to a significantly higher risk of incurring non-refundable module replacement costs during the 16th to 25th year of operation. - **Lack of bifaciality in bifacial solar panels** - The Mono-Glass (is\_bifacial: false) configuration excludes reflected light from the back, which both the Sunpro TOPCon 210 BIFACIAL and the Canadian Solar TOPBiHiKu6 offer in ground-mounted and carport installations (+5–15% additional annual energy yield with a ground albedo of 0.2–0.5). In projects where bifaciality is a key design factor, this series loses its relative advantage compared to selected comparable products. - **Pricing premiums for technology ABC** - The production cost of ABC technology is higher than that of mass-produced TOPCon. In European markets, AIKO ABC modules are priced approximately 15–25% higher per Wattpeak compared to comparable TOPCon modules (e.g., Canadian Solar TOPBiHiKu6), increasing the CAPEX for installations. The premium is justified due to limited roof space, but it reduces profitability in large commercial projects with ample available space. ## About this series AIKO Stellar ABC N-Type Mono-Glass panels introduce revolutionary All Back Contact technology, which completely eliminates cell shading by front busbars. By moving all contacts to the back of the module, **ABC technology** ensures a maximum light absorption surface, which directly translates into the highest energy conversion efficiency available on the market. It is an ideal solution for investors seeking maximum yields from limited roof space, effectively solving the problem of energy losses found in traditional designs. The Stellar series stands out with its **partial shading optimization function**, allowing the system to operate efficiently even in difficult lighting conditions or with periodic surface dirt. The use of pure N-type silicon guarantees minimal degradation and an excellent temperature coefficient, ensuring that the modules maintain power stability even during summer heat. An aesthetic finish and **elegant design** without visible silver connections make the panels blend perfectly with modern premium architecture.

The AIKO Stellar ABC N-Type Mono-Glass series has been discontinued and is no longer offered as a new product. Individual units may still be available from distributors as leftover stock, but their availability is significantly limited. Those seeking a similar ABC technology from AIKO should consider currently produced series, such as Neostar, or newer Stellar variants with double glass. ### What is the ABC technology used in Aiko Stellar panels, and why is it a good choice? ABC (All Back Contact) is a technology in which all electrical connections are moved to the back of the solar cell. This completely eliminates shading from junction boxes, directly increasing light absorption. In Stellar panels, this allows for a module efficiency of up to 24.4%, meaning more energy from the same roof area than in PERC or TOPCon panels. ### How well do the Aiko Stellar 660W panels perform in high temperatures during the summer? Thanks to the use of N-type silicon, Stellar modules have a very favorable temperature coefficient, meaning lower power losses during hot weather compared to P-type (PERC) technologies. In practice, during the summer, when the panel temperature exceeds 25°C, N-type modules lose proportionally less power than older technologies, and therefore generate more energy on long, sunny days. ### What is the warranty on Aiko Stellar ABC N-Type Mono-Glass panels? The manufacturer offers a 15-year product warranty (for material and workmanship defects) and a 30-year performance warranty. The linear warranty ensures that after 30 years, the module will maintain at least 87.4% of its original rated power. AIKO is part of Tier 1 manufacturers, which confirms the company's financial stability and the reliability of fulfilling warranty obligations. ### Are Aiko Stellar ABC panels safer in terms of fire risk compared to standard modules? Yes, the All Back Contact architecture physically eliminates the formation of hot spots, or localized overheating of the solar cells, which are a major cause of fires in traditional panels with front busbars. The absence of front-facing busbars reduces the number of vulnerable points, and the 3.2 mm thick monolithic glass further enhances the fire resistance of the entire module. ### Will the Aiko Stellar 660W solar panel perform adequately in partially shaded conditions, such as those caused by a chimney or trees? The Stellar series features a partial shading optimization function, which means that shaded cells reduce the overall module power output to a lesser extent compared to traditional designs. The N-type ABC technology minimizes losses due to the bypass effect, which is particularly important on roofs with chimneys, dormer windows, or nearby trees, where at least part of the panels may be shaded at times. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EN-192-72-AIKO-G-MCH72Mw-625-660W-2382x1134x30mm-EN-V62-d9f8c78d25dd.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Lighter, +1.0 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +25 W, lighter, +1.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +20 W, lighter, +0.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -10 W, lighter, +0.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +45 W, heavier, +0.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +40 W, heavier, +0.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +15 W, lighter, +0.6 pp | | [AIKO AIKO-G625-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g625-mch72mw) | 625 W | -30 W, -1.1 pp | | [AIKO AIKO-G630-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g630-mch72mw) | 630 W | -25 W, -0.9 pp | | [AIKO AIKO-G635-MCH72Dw](https://comparepv.com/panel/aiko-aiko-g635-mch72dw) | 635 W | -20 W, heavier, -0.7 pp | | [AIKO AIKO-G640-MCH72Dw](https://comparepv.com/panel/aiko-aiko-g640-mch72dw) | 640 W | -15 W, heavier, -0.5 pp | | [AIKO AIKO-G645-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g645-mch72mw) | 645 W | -10 W, -0.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +15 W, lighter, +0.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +15 W, heavier, +0.6 pp | --- Source: https://comparepv.com/panel/aiko-aiko-g655-mch72mw 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.
