For projects involving PV farms and commercial properties with long-term investment horizons, this translates to reduced residual risk and improved project bankability. - **Tier 1 BNEF – 16th consecutive confirmation** - AE Solar has been included in the BloombergNEF Tier 1 Global Solar Module Manufacturer list for the 16th time (Q1 2025), meeting the stricter criteria of 10 MW in non-recourse-funded projects from 6 independent banks. This status directly translates to greater access to financing for PV projects in Poland and the EU, without requiring additional security. - **Enhanced PERC resistance to humid conditions** - Research from 2025 (ScienceDirect) indicates that PERC modules, after 1000 hours of damp-heat testing, lose only 1–2% of their power, while TOPCon modules – which are the most common in this series – experience losses ranging from 4% to as high as 65%. In a climate with higher relative humidity, PERC therefore demonstrates better long-term stability compared to the newer N-type technology. - **Reliable performance in a 132-cell PERC (Passivated Emitter and Rear Cell) configuration.** - The range of 20.63–21.27% represents the upper limit of performance achievable with P-type PERC technology in a 132-cell half-cut configuration, as confirmed by the Ver24.5.1 datasheet. For commercial and PV farm installations, where consistency of parameters across the entire batch is crucial, the series offers a narrow variation in efficiency (0.64 pp). - **Certified resistance to aggressive environments** - The datasheet confirms resistance to ammonia, saline mists, sand, and dust – important certifications for installation in agricultural, port, and industrial facilities. The manufacturer, with 20 years of experience (founded in 2003, HQ in Germany) and a proven presence in the European market, provides an additional guarantee of service availability. ## Cons - **Efficiency is approximately 3 percentage points lower than that of comparable companies.** - Longi Hi-MO 9 and Canadian Solar TOPBiHiKu6 achieve 24.4% efficiency, while Sunpro TOPCon reaches 23.32%. In contrast, AURORA ME-132 achieves 20.63–21.27% efficiency. The difference of approximately 3% means that, with the same roof/ground area, the competition will produce about 12–18% more energy – a significant advantage in projects with limited space. - **P-type PERC – exhibits a higher LID degradation compared to TOPCon.** - The P-type PERC technology exhibits a first-year degradation rate of approximately 2% (LID) compared to the ~1% for N-type TOPCon used by all three comparable products in this series. Over a 30-year lifespan, the difference in cumulative energy production could be 2–4% in favor of TOPCon modules – a significant cost advantage for large-scale projects. - **Lack of bifaciality in bifacial solar panels** - The Sunpro TOPCon 210 and Canadian Solar TOPBiHiKu6 are bifacial modules, and when installed with a reflective surface (albedo of 0.2–0.3 on ground-mounted farms), they generate an additional 5–15% of energy. The AURORA ME-132, as a monofacial module, does not utilize this effect, making it less competitive in the segment of large-scale ground-mounted PV farms. ## About this series The AE Solar AURORA ME-132 series are monofacial modules designed for high energy production where predictability and stable performance in real-world conditions are key. The use of **P-type PERC** cells allows for efficient utilization of solar radiation even under less-than-ideal conditions, which is important in the Polish climate and with occasional cloud cover. The design, based on a modern cell layout and refined laminate, provides **improved tolerance to partial shading** - a practical solution for roofs with obstructions, chimneys, or neighboring buildings. These modules are designed for **durability and resilience** in typical commercial applications and larger installations, where consistent performance over time is essential. The AURORA ME-132 also stands out for its focus on quality and degradation control, which translates to **more reliable energy production** over the course of a year. It is a good choice for PV farms, warehouses, and industrial facilities, as well as projects where consistent results are the priority, rather than compromises in materials. ## Notable figures - At 20.6% efficiency, this panel is 0.8pp below the \*\*PERC 600-650W\*\* median of 21.4% - 206.3 W/m² power density is 7.5 W/m² below \*\*PERC 600-650W\*\* median (213.8 W/m²) - requires larger installation area - Temperature coefficient of -0.34%/°C matches the \*\*PERC 600-650W\*\* median - At 31.5 kg, this panel is 2.5 kg lighter than \*\*PERC 600-650W\*\* median (34.0 kg) - easier handling during installation - In the top 79% for efficiency among all PERC panels ## Questions ### What is the warranty on AE Solar AURORA ME-132 solar panels? The AURORA ME-132 series comes with a 30-year product warranty and a 30-year performance warranty. As a Tier 1 manufacturer based in Germany, AE Solar guarantees that after this period, the modules will retain more than 87% of their nominal output power. This is one of the longest warranties available on the market, which directly translates to greater certainty of return on investment over a long timeframe. ### Will AE Solar AURORA ME-132 660W solar panels be suitable for roofs in Poland that have chimneys or dormer windows? Yes, the AURORA ME-132 is designed for installations where partial shading is a challenge. Its 132-cell array and refined laminate increase the module's tolerance to shading, allowing for partial obstruction of the surface without significantly impacting performance. In the Polish climate, with its variable sunlight and architectural obstructions, this feature effectively reduces energy losses compared to older designs. ### Is the AURORA ME-132 a bifacial or monofacial panel? The AURORA ME-132 is a monofacial module, meaning it only generates power from one side. Power is obtained exclusively from the front side, which distinguishes this series from bifacial versions (ME-132BD). In typical roof installations on pitched roofs where reflection from the ground is minimal, the monofacial design is not a disadvantage, and it simplifies the design and installation of the entire system. ### What technology does the AE Solar AURORA ME-132 series use, and what are the practical implications of this? AURORA ME-132 modules utilize P-type PERC cells doped with Gallium (Ga-doped). The addition of Gallium reduces the LID (Light-Induced Degradation) effect, which is the decrease in power output in the initial weeks of operation, typical of older Boron-based cells. In practice, this means a more stable energy production from the very first day of operation and a smaller actual decrease in yield over the entire lifespan of the installation. ### Which type of installation is the AE Solar AURORA ME-132 module, with a maximum power output of 660 W, best suited for? The AURORA ME-132 660 W series is primarily designed for larger commercial and industrial projects: photovoltaic farms, production halls, warehouses, and public facilities. The high individual power output allows for a reduced number of modules and simplifies wiring. This series is ideal for applications where consistent parameters and reliable operation for at least three decades are crucial. ### Does the AE Solar AURORA ME-132 have quality certifications, and is the manufacturer reputable? AE Solar is a Tier 1 manufacturer based in Germany, with a presence in the market since 2003. The AURORA ME-132 series modules have IEC, TUV, and CE certifications, as well as ISO certification. The series has undergone tests for ammonia, saline mist, sand, and dust resistance, as well as PID (Potential Induced Degradation) tests. The Tier 1 status and the manufacturer's European headquarters are important factors to consider when assessing the financial risks of project financing and warranty claims. ## 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, +4.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +40 W, cooler, +4.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +35 W, cooler, +4.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +4.4 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +4.2 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +30 W, cooler, +4.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +4.2 pp | | [AE Solar AE ME-132 645W](https://comparepv.com/panel/ae-solar-ae-me-132-645w) | 645 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +165 W, heavier, +4.5 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +160 W, heavier, +4.3 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +155 W, heavier, +4.2 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +150 W, heavier, +4.0 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +120 W, cooler, +3.9 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +145 W, heavier, +3.8 pp | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +140 W, cooler, +3.7 pp | | [AIKO AIKO-A780-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a780-grh78dw) | 780 W | +140 W, heavier, +3.7 pp | --- Source: https://comparepv.com/panel/ae-solar-ae-me-132-640w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
