In the 2024 bankability ranking, it ranked 18th out of 67 manufacturers with a score of 50%, which directly translates to the ease of securing project financing (non-recourse) and lower investment risk. - **30-year product and performance warranty** - The AURORA ME-132 series offers a 30-year product warranty and a 30-year linear power warranty. Comparable products in this segment – Longi Hi-MO 9 and Canadian Solar TOPBiHiKu6 – typically offer a 25-year power warranty, making AE Solar's warranty terms significantly more advantageous for projects with a long-term investment horizon. - **Gal-doping eliminates LID degradation** - The use of gal-doped cells eliminates light-induced degradation (LID), which in standard PERC p-type (boron-oxygen) cells causes a power loss of up to 2% within the first year of operation. This allows the module to maintain its full nominal power from day one, distinguishing it from cheaper PERC alternatives without gal doping. - **Half-Cut + 9-bar Multi-Busbar** - The design of half-cut cells (132 cells in a 6x11 array) combined with a 9-bar Multi-Busbar system reduces resistive losses and limits the propagation of microcracks. In practice, this means improved performance under partial shading (where only half of the module is shaded) and increased mechanical strength – which is crucial for complex roof structures. - **Optimized for low-light conditions** - The manufacturer claims to have optimized the solar cells for operation under low light conditions (Low Light Performance), which is a significant advantage in the Polish climate, where the number of hours with diffuse solar radiation is high. This allows for higher annual yields than would be expected based solely on the STC (Standard Test Conditions) efficiency. ## Cons - **Performance is 3 pp lower than that of top-performing peers** - The maximum efficiency of the series is 21.27%, while direct comparisons with other products achieve 23.32% (Sunpro TOPCon 210) and 24.4% (Longi Hi-MO 9, Canadian Solar TOPBiHiKu6). This difference of approximately 3 percentage points means that, for the same power output, approximately 14% more roof or ground space is required. - **PERC technology – higher degradation rate compared to TOPCon** - Despite the LID (light-induced degradation) effect, PERC (p-type) cells exhibit an annual degradation rate of approximately 0.6–0.8%, while N-type TOPCon cells used by Longi and Canadian Solar degrade at a rate of approximately 0.4–0.5% per year (data: ScienceDirect 2025, Anern 2025). Over a 30-year warranty period, this difference accumulates to several percentage points of the actual power loss. - **Lack of bifaciality in peer comparisons** - The AURORA ME-132 series is monofacial (is\_bifacial: false), while two of the three comparable panels – Sunpro TOPCon 210 BIFACIAL and Canadian Solar TOPBiHiKu6 – offer additional power generation from the rear side of the panel (typically +5–15% under favorable conditions: clear surface, ground mounting, high albedo). This limits the potential energy output of the series for ground-mounted and flat-roof installations. ## About this series The AE Solar AURORA ME-132 series defines new standards of durability through the use of **gallium-doped cell technology**, which effectively eliminates the problem of light-induced degradation (LID) and guarantees stable power for decades. These panels utilize an advanced **Half-Cut cell** design, which, combined with the Multi-Busbar system, minimizes resistance losses and reduces the risk of micro-cracks. For the investor, this means higher resistance to mechanical damage and better performance in partial shading conditions, which is crucial on complex roof surfaces. A unique feature of the AURORA line is its optimization for operation at low irradiance levels, allowing for the **maximization of energy yields** on less sunny days, typical of the Polish climate. The ME-132 series is dedicated to both demanding residential installations and large commercial projects, where reliability and a fast return on investment are key. The use of **top-class silicon components** distinguishes these modules from cheaper competitors, offering users the confidence that the system will remain efficient even in extreme weather conditions. It is a solid solution for those seeking technology resistant to the passage of time and changing external factors. ## Notable figures - Efficiency of 21.3% matches the \*\*PERC 650-700W\*\* median - Power density of 212.7 W/m² matches the \*\*PERC 650-700W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 650-700W\*\* panels - 31.5 kg weight - 3.0 kg lighter than \*\*PERC 650-700W\*\* median (34.5 kg), reducing installation effort - In the top 63% for efficiency among all PERC panels ## Questions ### What warranty is offered for AE Solar AURORA ME-132 solar panels? The AURORA ME-132 series is covered by a 30-year product warranty and a 30-year performance warranty. This is one of the longest warranties available on the market for photovoltaic panels. The manufacturer, AE Solar, is a German-based company that ranks in Tier 1 of the global ranking, providing additional assurance regarding the long-term financial stability of the warranty provider. ### Will the AE Solar AURORA ME-132 panels perform well in the Polish climate, particularly under cloudy conditions? Yes. The AURORA ME-132 series has been optimized for operation under low radiation levels, making it a particularly suitable choice for Poland. The technology using gallium-doped PERC (Passivated Emitter and Rear Cell) solar cells minimizes light-induced degradation, and the half-cut cells provide higher productivity in cloudy conditions, which are typical for Poland for a significant portion of the year. ### This means that the cells in the AURORA ME-132 are doped with gallium, and why is this important? Gallium doping (Ga-doping) is a modification of the silicon structure of the solar cell that effectively eliminates the LID (Light-Induced Degradation) phenomenon, which is the degradation caused by the initial hours of exposure to sunlight. In traditional boron-based cells, the power output can decrease by as much as 1-3% immediately after installation. The AURORA ME-132 does not suffer from this problem, which means higher energy yields from the very first day of operation and better power stability over the entire 30-year lifespan. ### What is the weight of the AE Solar AURORA ME-132 panel, and will my roof be able to support the installation? The individual AURORA ME-132 module weighs approximately 40.5 kg and has dimensions of 2383 x 1302 x 30 mm. It is a high-performance panel (660 Wp), so it is larger and heavier than typical 400-430 Wp residential panels. It is advisable to have a qualified engineer assess the roof's load-bearing capacity before installation, especially for older buildings or roofs with lightweight rafters. ### Is the AURORA ME-132 660W suitable for large commercial and solar farm installations? Yes, the ME-132 series, with a peak power of 660 Wp, is designed for both large rooftop installations and commercial projects, as well as ground-mounted farms. The high power of individual units allows for a reduction in the number of modules required for a given installation power, which translates to lower costs for supporting structures, cabling, and labor. The manufacturer is part of Tier 1 suppliers, which facilitates bank financing for projects. ### How does the Half-Cut technology in the AURORA ME-132 affect the panel's performance under partial shading? In the AURORA ME-132, each cell is cut in half, creating 132 smaller cells instead of the standard 66. The panel is internally divided into two independent electrical sections. This means that shading by a chimney or antenna on half of the module only affects that specific section, rather than the entire panel. The Multi-Busbar system further shortens the current paths and reduces the risk of micro-cracks. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-me-132-640w-660w-sc-11-5-ver25-9-1-b7fc63c03d4b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.7 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +40 W, cooler, +3.7 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +35 W, cooler, +3.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.5 pp | | [AE Solar AE ME-132 640W](https://comparepv.com/panel/ae-solar-ae-me-132-640w) | 640 W | -20 W, -0.6 pp | | [AE Solar AE ME-132 645W](https://comparepv.com/panel/ae-solar-ae-me-132-645w) | 645 W | -15 W, -0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +145 W, heavier, +3.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +140 W, heavier, +3.6 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +135 W, heavier, +3.5 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +130 W, heavier, +3.3 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +100 W, cooler, +3.2 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +125 W, heavier, +3.1 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +120 W, cooler, +3.0 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-me-132-660 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
