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.

What owners get
N-type TOPCon – lower degradation and LID resistance

N-type TOPCon cells exhibit an annual degradation of ≤0.4% (compared to ~0.45% for PERC), and are free from the LID effect associated with boron-oxygen pairing. 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.

Trade-offs
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.

Common questions

6 answered
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.
