This makes the series suitable for installation in areas with heavy snowfall and strong winds. - **30-year linear warranty on power** - The manufacturer guarantees that the product will maintain more than 80% of its nominal power for 30 years, backed by a 30-year product warranty. This 30-year warranty period is longer than the standard 25-year warranty periods offered by many competitors in the PERC segment. - **Half-cell PERC + multi-busbar (144 cells)** - The 144-cell configuration with a central bypass diode reduces resistive losses and improves resistance to microcracks and partial shading, resulting in higher efficiency at low illumination levels compared to standard full-cell modules without MBB (Micro-Battery Bypass). - **Certified resistance to PID and environmental conditions** - The series has passed tests according to IEC TS 62804 (PID), IEC 61701 (salt spray), IEC 62716 (ammonia), and hail tests. The set of certificates includes IEC 61215, IEC 61730, UL 1703, and CE – which allows for use in installations exposed to aggressive industrial and coastal environments. - **Efficiency of up to 21.27% in the PERC class** - The maximum efficiency of 21.27% places the series in close competition with comparable JS Solar and Jinko Solar JS182MHC120 (21.48%) modules. This represents a solid technological achievement for its generation, considering it's a PERC module from 2020. ## Cons - **Production is complete – limited availability** - The series has been discontinued (released in 2020). Availability is limited to existing stock held by distributors; there is no ongoing service support and it is difficult to obtain replacement modules for expansion or to replace damaged units. - **Performance is 1.51 percentage points below the segment leader.** - A comparable DAH DHN-54R18/DG(BW) achieves 22.78% efficiency, compared to the maximum 21.27% of the AS-6M144-HC series. This difference of 1.51% indicates that the DAH installation, with the same roof area, will actually produce more energy. - **Outdated P-type PERC technology (2020)** - From 2022-2023, the premium segment has been dominated by N-type TOPCon and HJT cells, which offer a lower LID degradation rate, better temperature coefficients, and higher efficiencies (>22%). The 2020 PERC module does not match these parameters. - **Reported issues with warranty service** - Independent reports from commercial installations (3.6 MW) indicate negative results from TÜV Rheinland tests, which are inconsistent with the declared power tolerance, as well as very poor handling of warranty claims. This poses a significant risk, particularly in large investments where enforcing warranties is crucial. - **Lack of bifaciality when comparing to similar peers** - The module is monofacial (is\_bifacial: false), while the DAH DHN-54R18/DG(BW) offers a bifacial design. When mounted on reflective surfaces (concrete, gravel, snow), the potential yield loss is estimated to be 5–15% per year. ## About this series The **AS-6M144-HC** series consists of premium-class monocrystalline photovoltaic modules, designed for maximum performance in both large commercial installations and demanding prosumer systems. The key to their high efficiency is the combination of **Half-Cell PERC** technology with a 144-cell array and the use of **multi-busbar** - a greater number of collecting bars minimizes resistive losses and improves resistance to microcracks, which are a common cause of degradation in competing modules. This allows the modules to maintain excellent operating parameters even under partial shading and in low-sunlight conditions. The series is distinguished by its proven **PID resistance** (potential-induced degradation), which is crucial in high-voltage systems. The robust construction with a durable aluminum frame allows it to withstand extreme loads from snow and wind, and the panels have passed salt fog, ammonia, and hail resistance tests. **Two-stage warranty** - product and power - ensures the security of your investment for decades, making this series an attractive choice for installers and investors who prioritize reliability. ## Notable figures - Efficiency of 21.0% matches the \*\*PERC 450-500W\*\* median - Power density of 210.4 W/m² matches the \*\*PERC 450-500W\*\* median - Temperature coefficient of -0.36%/°C matches the \*\*PERC 450-500W\*\* median - Ranked #9666 out of 14005 panels for efficiency in the database ## Questions ### What warranty is provided for the Amerisolar AS-6M144-HC panels? The AS-6M144-HC series comes with a two-tier warranty: a 20-year product warranty covering material and workmanship defects, and a 30-year linear power output warranty. The latter guarantees that the module will retain a specified percentage of its nominal power over three decades of operation, making this series a sound long-term investment for both residential prosumers and commercial energy investors. ### Is the AS-6M144-HC series still available for purchase? The AS-6M144-HC series has been discontinued and is no longer actively manufactured by Amerisolar. Availability through secondary markets or distributors holding existing stock remains possible, though increasingly limited. If you are planning a new installation, it is advisable to check with your supplier regarding current inventory levels or to consider newer Amerisolar series offering higher power outputs and conversion efficiencies. ### How does the Half-Cut PERC technology used in the AS-6M144-HC panels work? Half-cut cell technology involves splitting each cell in half, which reduces the current flowing through the module and lowers resistive losses. PERC (Passivated Emitter and Rear Cell) adds a passivation layer to the rear of the cell, reflecting uncaptured photons back into the active material. The combined result is a higher conversion efficiency (up to 21.27%) and improved performance under partial shading conditions compared to standard monocrystalline cells. ### What is the maximum power output of the Amerisolar AS-6M144-HC panel, and what type of installation is it suited for? The highest-power variant in the series achieves 465 Wp under STC conditions. This is a typical power rating for premium-class modules from the 2020–2022 period, suitable for both residential rooftop installations (5–15 kWp systems) and utility-scale solar farms. The module dimensions of 2102×1040×35 mm and a weight of approximately 24 kg are standard for 144-cell modules, ensuring broad compatibility with common mounting structures. ### Can the AS-6M144-HC panels withstand heavy snow loads and high wind speeds? Yes. The robust aluminum frame of the AS-6M144-HC modules is rated to withstand a snow load of up to 5400 Pa and a wind load of up to 2400 Pa. The series has also passed resistance tests for salt mist, ammonia, and hail, making it suitable for installation in diverse climatic conditions, including mountain and coastal locations in Poland. ### What is PID resistance, and do the Amerisolar AS-6M144-HC panels have it? PID (Potential Induced Degradation) is a module degradation phenomenon caused by high system voltage, resulting in progressive power loss. The AS-6M144-HC series has certified PID resistance, which is especially important in large string installations operating at high system voltages — even exceeding 1000 V. This ensures that the modules maintain stable power output throughout the entire warranty period without the need for additional protective measures. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/AS-6M144-HC-MODULE-a105c5088393.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +35 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +45 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +30 W, cooler, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +40 W, cooler, +3.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +40 W, cooler, +3.5 pp | | [Amerisolar AS-6M144-HC-430](https://comparepv.com/panel/artsolar-as-6m144-hc-430) | 430 W | -30 W, -1.6 pp | | [Amerisolar AS-6M144-HC-435](https://comparepv.com/panel/artsolar-as-6m144-hc-435) | 435 W | -25 W, -1.1 pp | | [Amerisolar AS-6M144-HC-440](https://comparepv.com/panel/artsolar-as-6m144-hc-440) | 440 W | -20 W, -0.9 pp | | [Amerisolar AS-6M144-HC-445](https://comparepv.com/panel/artsolar-as-6m144-hc-445) | 445 W | -15 W, -0.7 pp | | [Amerisolar AS-6M144-HC-450](https://comparepv.com/panel/artsolar-as-6m144-hc-450) | 450 W | -10 W, -0.5 pp | | [Amerisolar AS-6M144-HC-455](https://comparepv.com/panel/artsolar-as-6m144-hc-455) | 455 W | -0.2 pp | | [Amerisolar AS-6M144-HC-465](https://comparepv.com/panel/artsolar-as-6m144-hc-465) | 465 W | +0.2 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +130 W, cooler, +2.8 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +125 W, cooler, +2.6 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +120 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/artsolar-as-6m144-hc-460 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
