The Wiley/Progress in Photovoltaics (2025) study confirms that TOPCon modules do not exhibit increased LID or LeTID sensitivity, which translates into a realistically higher energy yield throughout the entire lifespan of the installation. - **High efficiency, similar to bifacial counterparts** - At its maximum efficiency of 22.83%, the monofacial module is comparable to bifacial modules currently on the market, such as the Horay Solar HS 182-144 TC-D Ocean, which achieves 22.80% efficiency as a bifacial module, and the DAH DHN-72X16/DG(BB) – 22.84%. Therefore, the Amerisolar AS-7M144N-HC achieves premium-level performance without the need for a double-sided construction. - **30-year linear power guarantee (≥87.4%)** - The manufacturer guarantees at least 87.4% of the nominal power after 30 years – a standard comparable to the top-tier TOPCon series from brands like Canadian Solar and Phono Solar. For comparison, older PERC series (e.g., JA Solar PERC) typically offer a 25-year warranty and a drop to approximately 84.8%. - **Mechanical strength suitable for the Polish climate** - The aluminum frame can withstand wind loads of 2400 Pa and snow loads of 5400 Pa, which is a significant advantage for this series in Poland, where there are often heavy snowfall. The system voltage of 1500 V allows for the creation of longer strings, reducing cabling costs in PV farm projects. ## Cons - **Product line discontinued (2022)** - The AS-7M144N-HC series has been discontinued since its initial release in 2022. This means that replacement panels may be difficult to obtain in the event of damage to long-term installations, and that warranty claims (20-year warranty) may be challenging to process once stock is depleted by distributors. - **Amerisolar is not included in the BNEF Tier 1 list.** - Amerisolar is not included in the BNEF Tier 1 bankability list (Q1 2026), which is dominated by Jinko, LONGi, Trina Solar, JA Solar, and Tongwei. The lack of Tier 1 status may make it difficult or impossible to obtain non-recourse financing for utility-scale projects with a capacity of over 1.5 MW, and could also increase the project's risk premium in a bank's assessment. - **Lack of bifaciality at a comparable price point for the segment** - The three comparable models in the 590 W segment, with an efficiency of approximately 22.8%, are either bidirectional or available in a bifacial (DAH DHN-72X16/DG(BB), Horay Solar HS 182-144 TC-D Ocean) configuration. The monofacial design of the AS-7M144N-HC eliminates the potential energy gain of 5–20% from reflected albedo, which represents a real loss in ground-mounted and white-membrane rooftop installations. ## About this series The **Amerisolar AS-7M144N-HC** series is a high-performance photovoltaic module based on **N-type TOPCon technology** with monocrystalline cells - a premium solution for installations that require maximum productivity with limited roof or ground space. The "N" in the model name indicates the use of N-type silicon, which has a lower degradation rate and better resistance to LID (Light Induced Degradation) compared to older PERC modules. The **Half-Cut cell (HC) technology** - 144 cut cells - results in reduced resistive losses and significantly improved partial shading resistance, which is crucial in urban and complex roof installations. A robust **wind-resistant aluminum frame up to 2400 Pa and snow up to 5400 Pa** makes the panels suitable for the challenging climate conditions of Poland. A system voltage of 1500V allows for the creation of longer strings, which reduces cabling costs in industrial installations and PV farms. The AS-7M144N-HC series is designed for both **premium-class prosumer installations** and utility-scale commercial projects, where reliability and long-term return on investment are key. ## Notable figures - Efficiency of 22.4% matches the \*\*TOPCon 550-600W\*\* median - Power density of 224.4 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - Weight of 27.5 kg (3.7 kg below \*\*TOPCon 550-600W\*\* median of 31.2 kg) allows easier transport and roof mounting - #4716 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### Is the Amerisolar AS-7M144N-HC series still available for purchase? The AS-7M144N-HC series has been discontinued and is no longer offered as a new product by Amerisolar. Availability on the secondary market or through distributors with remaining stock is limited. If you are planning a new installation, it is worth considering a current replacement based on TOPCon technology from Amerisolar or another manufacturer offering comparable power output and warranty terms. ### What is TOPCon technology in the Amerisolar AS-7M144N-HC panels, and is the premium price justified? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that delivers higher module efficiency — in the 590 W variant it approaches nearly 23%. Compared to older PERC cells, TOPCon exhibits a lower annual power degradation rate and a significantly reduced LID (Light-Induced Degradation) effect, meaning less power loss upon initial light exposure. For installations focused on long-term return on investment, this represents a clear advantage. ### What warranty is provided for the Amerisolar AS-7M144N-HC panels? The AS-7M144N-HC series is covered by a 20-year product warranty (against material and workmanship defects) and a 30-year linear power output warranty. This means the manufacturer guarantees that the modules will maintain a specified performance level for 30 years. Thanks to the low degradation rate characteristic of N-type cells, the modules should retain well above 80% of their nominal power output even after three decades of operation. ### Do the Amerisolar AS-7M144N-HC panels handle partial shading well, for example from a chimney or antenna? Yes. The use of 144 half-cut (HC) cells significantly reduces power losses caused by partial shading. Each cell operates at a lower current, which minimizes resistive heating and limits power loss in the shaded section. This design proves effective in practice on urban rooftops where a chimney, satellite dish, or dormer window may cause localized shading of the panel. ### Will the AS-7M144N-HC panels perform well in the Polish climate, where heavy snow and strong winds are common in winter? Yes. The aluminum frame of the AS-7M144N-HC modules withstands snow loads of up to 5,400 Pa and wind loads of up to 2,400 Pa, which comfortably meets the requirements for the vast majority of locations in Poland. N-type cells also have a lower temperature coefficient of power, which means they perform better on clear winter days that combine strong irradiance with low ambient temperatures. ### Are the Amerisolar AS-7M144N-HC 590 W panels compatible with standard inverters available in Poland? The AS-7M144N-HC modules support a system voltage of up to 1,500 V, which is compatible with the majority of modern three-phase inverters used in commercial and premium prosumer installations. For residential three-phase systems using 1,000 V inverters, string lengths must be planned carefully to ensure that the open-circuit voltage (Voc) does not exceed the inverter's input limit — it is advisable to consult a qualified system designer in such cases. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Amerisolar-580wp-e9e20715393f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -25 W, cooler, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, heavier, +2.0 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.0 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, lighter, +2.0 pp | | [Amerisolar AS-7M144-HC-525](https://comparepv.com/panel/artsolar-as-7m144-hc-525) | 525 W | -55 W, hotter, -2.1 pp | | [Amerisolar AS-7M144-HC-530](https://comparepv.com/panel/artsolar-as-7m144-hc-530) | 530 W | -50 W, hotter, -1.9 pp | | [Amerisolar AS-7M144-HC-535](https://comparepv.com/panel/artsolar-as-7m144-hc-535) | 535 W | -45 W, hotter, -1.7 pp | | [Amerisolar AS-7M144-HC-540](https://comparepv.com/panel/artsolar-as-7m144-hc-540) | 540 W | -40 W, hotter, -1.6 pp | | [Amerisolar AS-7M144-HC-545](https://comparepv.com/panel/artsolar-as-7m144-hc-545) | 545 W | -35 W, hotter, -1.4 pp | | [Amerisolar AS-7M144-HC-550](https://comparepv.com/panel/artsolar-as-7m144-hc-550) | 550 W | -30 W, hotter, -1.2 pp | | [Amerisolar AS-7M144N-HC-560](https://comparepv.com/panel/artsolar-as-7m144n-hc-560) | 560 W | -20 W, -0.8 pp | | [Amerisolar AS-7M144N-HC-565](https://comparepv.com/panel/artsolar-as-7m144n-hc-565) | 565 W | -15 W, -0.6 pp | | [Amerisolar AS-7M144N-HC-570](https://comparepv.com/panel/artsolar-as-7m144n-hc-570) | 570 W | -10 W, -0.4 pp | | [Amerisolar AS-7M144N-HC-575](https://comparepv.com/panel/artsolar-as-7m144n-hc-575) | 575 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, cooler, +2.8 pp | --- Source: https://comparepv.com/panel/artsolar-as-7m144n-hc-580 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.
