This places the series among the top performers in comparable 182mm modules on the market. - **The M10 format (182mm) reduces costs for BOS.** - A power density of 530–550W per 182mm module allows for a reduction in the number of modules and cable lengths in commercial and utility-scale installations, resulting in an estimated 3–5% reduction in BOS (Balance of System) costs compared to older 166mm formats, while maintaining the same system power. - **25-year performance guarantee** - The manufacturer guarantees power maintenance for 25 years – this is the standard for the segment, but with AIKO's Tier-1 status and the company's operations since 2009, the risk of a lack of an active service technician within that timeframe is significantly lower than with smaller suppliers. ## Cons - **PERC (P-type) in the era of TOPCon dominance** - The PERC technology exhibits a worse temperature coefficient (–0.35 to –0.40%/°C) compared to N-type TOPCon (–0.29 to –0.32%/°C) and shows a higher annual degradation rate (0.6–0.8% vs 0.4–0.5% for TOPCon). Over a 25-year lifespan, this difference translates to a significantly lower cumulative energy yield; by 2025–2026, TOPCon is already the standard price point in this power segment. - **12-year product warranty** - The 12-year product warranty is shorter than the 15 years offered by some Tier-1 manufacturers in the premium segment (e.g., LONGi Hi-MO 6, JA Solar DeepBlue 4.0 Pro). This reduces the warranty coverage for mechanical failures by 3 years for installations with a planned lifespan of 25+ years. - **Designed for single-sided use only – no bifacial gain** - The absence of a rear glass prevents bifacial gain. In ground-mounted and rooftop installations with similarly sized modules, bifacial modules achieve 5–15% higher annual energy yield. Among comparable products, the Goldi Solar GS10-B144-TF offers a bifacial version with the same 550W power rating. ## About this series The AIKO M-144 (182mm Cell) 530-550W Monofacial Module is designed to maximize energy yield from any available mounting surface, without compromising durability and aesthetics. A key advantage is the **N-type ABC (All Back Contact) technology**, in which all electrical connections are located on the back of the cell. This keeps the front free from shading by racking systems, which translates to better light utilization even in less sunny conditions. In practice, this series helps address common investor concerns: **higher power density on the roof**, improved performance at elevated temperatures, and **greater resistance to microcracks and degradation**, which are characteristic of older technologies. It is a good choice for commercial and industrial installations, PV farms, and large roofs, where a quick return on investment and stable energy production over the long term are important. It stands out from the competition due to its **front-side metallization-free design**, which supports both performance and long-term reliability. ## Notable figures - At 20.7% efficiency, this panel is on par with typical \*\*PERC 500-550W\*\* modules - Power density of 207.0 W/m² matches the \*\*PERC 500-550W\*\* median - At -0.36%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - #10764 for efficiency, #12345 for temperature performance out of 14005 panels ## Questions ### What is the ABC technology used in AIKO M-144 panels, and why is it superior to traditional solar cells? ABC (All Back Contact) is a solar cell design in which all electrical connections are moved to the back of the module. This results in a completely clear front surface, allowing for more active area to absorb sunlight. In practice, this translates to AIKO M-144 modules achieving efficiencies of up to 25%, as well as improved performance in cloudy or diffuse light conditions, which is difficult to achieve with standard PERC or TOPCon cells. ### What is the warranty on Aiko M-144 530-550W solar panels? The manufacturer offers a 12-year product warranty and a 25-year performance warranty. Due to a low annual degradation rate of approximately 0.35% after the first year, the modules retain over 90% of their original power even after 30 years of operation. This is one of the best durability indicators available on the market for Tier 1 commercial-grade modules. ### Do the AIKO M-144 solar panels experience a significant drop in power output during the summer months at high temperatures? The N-type ABC technology provides a temperature coefficient of approximately -0.26%/°C, which is significantly better than typical PERC modules (-0.35%/°C) or many TOPCon models. This means that on a hot day at 70°C, the AIKO M-144 550W module loses less power than its competitors, directly translating to higher annual energy yield in warm climates and on exposed roofs. ### Are Aiko M-144 550W solar panels suitable for large commercial installations and solar farms? Yes, the M-144 series, featuring 182mm cannons and power output up to 550W, is primarily designed for commercial, industrial, and solar farm installations. Its high power density per square meter allows for maximizing energy production on limited roof or ground space. The modules are compatible with standard three-phase inverters and mounting structures designed for the 182mm format. ### Are the ABC cells in the AIKO M-144 series more resistant to micro-cracks than standard modules? Yes. The absence of metallic busbars on the front of the module reduces the mechanical stress, which is the main cause of microcracks in traditional modules. The N-type modules produced by Aiko are also less susceptible to light-induced degradation (LID) and humidity-induced degradation (LETID), as confirmed by independent tests. The manufacturer states that the hot-spot temperature is more than 30% lower compared to TOPCon modules of similar power. ### What is the maximum power output of the Aiko M-144 panel, and what power options are available for this series? The AIKO M-144 (182 mm Cell) series includes monofacial modules with a power output ranging from 530 W to 550 W. The top-end 550 W version, with 144 cells and an efficiency of up to 25%, is one of the most efficient commercially available modules on the market. The specific power variant chosen depends on the project requirements, available space, and inverter configuration. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/550W-Solar-panels-bd623cd3b8a3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +4.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.1 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +4.1 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +4.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.8 pp | | [AIKO M530M-144](https://comparepv.com/panel/aiko-m530m-144) | 530 W | Very close match | | [AIKO M540M-144](https://comparepv.com/panel/aiko-m540m-144) | 540 W | Very close match | | [AIKO M545M-144](https://comparepv.com/panel/aiko-m545m-144) | 545 W | +10 W, +0.4 pp | | [AIKO M550M-144](https://comparepv.com/panel/aiko-m550m-144) | 550 W | +15 W, +0.6 pp | | [AIKO AIKO-A-600-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-600-mah72mw) | 600 W | +65 W, cooler, +2.5 pp | | [AIKO AIKO-A-605-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-605-mah72mw) | 605 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A-610-MAH72Mw](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a-610-mah72mw) | 610 W | +75 W, cooler, +2.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +115 W, cooler, +4.5 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +110 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/aiko-m535m-144 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
