For projects funded by banks or investment funds, the lack of a "bankable" status could exclude this series from the list of approved suppliers or increase the required level of financial security. - **Efficiency: 20.13–21.27% – below comparable benchmarks** - The best variant of the series achieves 21.27%, while the JS Solar JS182MHC120 offers 21.48%, and the DAH DHN-54R18/DG(BW) achieves 22.78% – this means that, for the same roof area, there is a real reduction in energy yield or the need to install a larger number of modules. - **P-type PERC technology – higher LID and degradation compared to N-type** - PER (P-type) cells exhibit higher degradation after the first year of operation (around 2% LID) and an annual degradation rate of 0.5–0.7%, compared to N-type TOPCon cells (around 1% and 0.25–0.4% annually). The comparable DAH technology offers bifacial N-type cells, which results in significantly higher cumulative yield over a 25-year period. - **12-year product warranty – below the market standard** - Leading manufacturers from Tier 1 (Jinko Solar, JA Solar, Trina) typically offer standard product warranties of 15-25 years. AmoSolar, on the other hand, offers a warranty of only 12 years, which reduces the period of protection against material and manufacturing defects – a significant risk factor in long-term service agreements. ## About this series The AmoSolar AS440-465M6-144 series comprises monocrystalline PERC modules in a **half-cut** configuration, designed for high energy production under realistic rooftop and ground conditions. The splitting of the cells reduces internal resistance losses, allowing the panel to better handle partial shading and maintain a more stable power output, even when exposed to dirt, chimneys, or neighboring buildings. The use of popular **M6 cell** format facilitates component availability and aligns with the standards of many commercial projects. The module is also prepared for use in higher voltage systems, enabling more flexible design of longer strings and optimized cabling. In practice, this series addresses two key issues for investors: reducing energy yield in less-than-ideal conditions and supporting profitability through a longer lifespan - **a solid product warranty and power warranty** increase predictability of returns. This is a good choice for homes, businesses, and PV farms, where **reliability and high energy yield per square meter** are important. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 450-500W\*\* modules - At 213.9 W/m² power density, this panel generates 5.4 W/m² more per unit area than \*\*PERC 450-500W\*\* median (208.5 W/m²) - Temperature coefficient of -0.35%/°C matches the \*\*PERC 450-500W\*\* median - Weight of 23.0 kg (1.5 kg below \*\*PERC 450-500W\*\* median of 24.5 kg) allows easier transport and roof mounting - In the top 63% for efficiency among all PERC panels ## Questions ### What warranty is offered on the AmoSolar AS440-465M6-144 panels? The AmoSolar AS440-465M6-144 series comes with a 12-year product warranty covering material and workmanship defects, as well as a 25-year linear power output warranty. The linear power warranty guarantees a gradual, predictable degradation in energy production over a quarter century, making it significantly easier to model return on investment for both residential and commercial installations. ### Do the AmoSolar AS440-465M6-144 panels perform well under partial shading, such as from a chimney or dormer window? Yes. The AS440-465M6-144 series employs half-cut cell technology, which splits each cell into two halves and substantially reduces power losses caused by partial shading. When a portion of the module is shaded by a chimney, antenna, or adjacent roof section, the remaining cells continue to operate more efficiently than they would in conventional full-cell modules. This is a meaningful advantage in typical urban and suburban rooftop environments. ### What is the peak power output of the most powerful panel in the AmoSolar AS440-465M6-144 series? The highest peak power rating in this series is 465 Wp. The series spans a range from 440 to 465 Wp, allowing integrators to select the appropriate variant based on available roof area or specific project requirements. The M6 cells arranged in a 144 half-cut configuration achieve this output while maintaining a respectable module efficiency per square meter. ### Are the AmoSolar AS440-465M6-144 panels bifacial? No, the AS440-465M6-144 series consists of monofacial modules. Energy is generated exclusively through the front glass-covered surface. This means the installation does not require a light-reflective ground surface or specialized racking systems with elevated clearance, which simplifies mounting on standard pitched and flat roofs. ### Can AmoSolar AS440-465M6-144 modules be used in longer strings and higher-voltage system designs? Yes. The AS440-465M6-144 series is rated for elevated system voltages, enabling the design of longer strings. This is a practical advantage in large commercial rooftop installations and PV farms, where longer strings reduce the overall DC cabling run and simplify the electrical system design. ### What is the PERC technology used in the AmoSolar AS440-465M6-144 panels, and does it justify the cost? PERC (Passivated Emitter and Rear Cell) is a variant of monocrystalline cell technology that incorporates an additional reflective passivation layer on the rear surface of the cell. Light that passes through the cell without being absorbed is reflected back, giving it a second opportunity to generate current. In practice, this translates to higher module efficiency and improved performance under diffuse, overcast light conditions. At current market pricing, PERC has become the industry standard and is comparably priced to conventional modules, making it a straightforward choice rather than a premium add-on. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/72deabdf515591ce9b56b7c68601e67d-d4ed416e97ce.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.2 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.2 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +3.2 pp, +5 yr warranty | | [AmoSolar AS440M6-144](https://comparepv.com/panel/amosolar-as440m6-144) | 440 W | -25 W, -1.1 pp | | [AmoSolar AS445M6-144](https://comparepv.com/panel/amosolar-as445m6-144) | 445 W | -20 W, -0.9 pp | | [AmoSolar AS450M6-144](https://comparepv.com/panel/amosolar-as450m6-144) | 450 W | -15 W, -0.7 pp | | [AmoSolar AS455M6-144](https://comparepv.com/panel/amosolar-as455m6-144) | 455 W | -10 W, -0.5 pp | | [AmoSolar AS460M6-144](https://comparepv.com/panel/amosolar-as460m6-144) | 460 W | -0.2 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +125 W, +2.6 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +120 W, +2.4 pp, +5 yr warranty | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +115 W, cooler, +2.2 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +115 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/amosolar-as465m6-144 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
