This represents a significant advantage when calculating project financing and assessing banking risk. - **The only European Tier 1 BNEF with high bankability** - AE Solar has been included in the BNEF Tier 1 list for the 16th consecutive quarter (Q1 2025), and as the only European manufacturer, it achieved a "High Bankability" rating in 2024 (the bankability indicator increased from 26% in 2023 to 50% in 2024). This is a key argument for projects financed by banks – the manufacturer is viewed as an exceptionally safe and reliable partner compared to Asian alternatives. - **Half-cut solar panels + Ga-doped PERC cells** - The use of half-cut cells reduces mismatch losses by approximately 50% compared to standard cells when partially shaded. Gallium doping minimizes the LID (Light-Induced Degradation) effect, which is a major weakness of conventional p-type PERC cells. - **25 different power options, ranging from 395 to 660 Wp** - The range of 395 to 660 W, available in 25 variants, allows for precise selection of modules for both small residential and industrial/commercial installations, as well as ground-mounted systems – without the need to compromise between individual power output and adaptation to the roof area. - **Kiwa PVEL Top Performer 2025** - AE Solar has been awarded the Kiwa PVEL Top Performer Award 2025 in independent performance tests of photovoltaic modules, confirming the declared parameters under real-world conditions – not just in laboratory settings. ## Cons - **PERC's efficiency is noticeably lower than that of TOPCon technology.** - The maximum efficiency of the AURORA module is 21.35%, while direct comparisons with N-type TOPCon technology-based modules achieve 23.32–23.8% (HY Solar: 23.8%, Talesun BIPRO: 23.7%, PolyCrown: 23.32%). This difference of 2–2.5% corresponds to approximately 10–11% less power generated from the same roof area. Furthermore, TOPCon modules exhibit lower annual degradation (approximately 0.40% vs. approximately 0.55% for PERC) and are free from the LID (light-induced degradation) effect – which has a significant impact on the overall energy yield over a 30-year lifespan. ## About this series The AE Solar AURORA series consists of modules based on a proven PERC technology with monocrystalline silicon solar cells, developed with a focus on high operational stability in real-world conditions. The use of **half-cut cells** helps to minimize losses due to partial shading and improves the performance of rooftop installations with obstructions such as chimneys or skylights. Thanks to **good performance in diffuse light**, AURORA can maintain a solid yield even on cloudy days, which is important in the Polish climate. A key feature of the series is the emphasis on long-term reliability - the solutions used aim to **limit LID degradation**, and the design is intended for durability in more challenging environmental conditions. Depending on the project requirements, there are options for both **mono and bifacial** modules, making it easy to choose the right option for rooftop, carport, and larger ground-mounted systems. AURORA is a good choice for investors who expect predictable yields, flexible project design, and technology without unnecessary risks. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 650-700W\*\* modules - Power density of 212.7 W/m² matches the \*\*PERC 650-700W\*\* median - Temperature coefficient of -0.34%/°C matches the \*\*PERC 650-700W\*\* median - At 37.0 kg (2.5 kg above \*\*PERC 650-700W\*\* median of 34.5 kg), requires checking roof load capacity - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What kind of warranty do AE Solar AURORA panels offer? The AE Solar AURORA series comes with a 30-year product warranty and a 30-year performance warranty. The manufacturer guarantees that after 30 years of operation, the panel will maintain at least 87% of its nominal output power. Degradation in the first year does not exceed 2.5%, and from the second year, it is a maximum of 0.55% per year. This is one of the most comprehensive warranties available on the market for PERC panels. ### Do AE Solar AURORA panels perform well in cloudy conditions and in the Polish climate? Yes. The AURORA series has been designed for optimal performance in diffused light, which is particularly important in Poland, where cloudy days are common. The use of half-cut modules further minimizes losses in partially shaded conditions. This allows the installation to maintain a stable energy yield even in less favorable solar conditions. ### What is the maximum power output of the AE Solar AURORA series panels, and for what types of installations are they suitable? The highest power variant in the AURORA series reaches 660 Wp, placing it in the segment of high-power modules primarily designed for ground-mounted installations, carports, and larger commercial systems. Smaller power variants from the same series are available for roof-mounted installations on residential buildings. It is always advisable to choose a model that is suitable for the roof's load-bearing capacity and available space. ### What is PERC technology with half-cut cells, and why does the AURORA series use it? PERC (Passivated Emitter and Rear Cell) is an advanced technology for monocrystalline solar cells that incorporates an additional rear passivation layer, which enhances light absorption and improves efficiency. Half-cut cells divide each cell into two parts, reducing internal resistance and limiting the impact of shading on the overall module's performance. The combination of these features in the AURORA series results in higher performance and stability in everyday operation. ### Is AE Solar a reputable manufacturer, and do the AURORA panels have quality certifications? AE Solar is a German-based manufacturer classified as Tier 1 by independent industry agencies, indicating strong financial stability and a well-established market position. The AURORA series was awarded the "Top Performer 2025" title by Kiwa PVEL, one of the most respected independent photovoltaic module testing laboratories. This certification confirms that the panels meet stringent quality and durability standards. ### Are AE Solar AURORA panels suitable for roofs with chimneys or dormer windows? Yes, the AURORA series is suitable for roofs with obstructions. The use of half-cut cells divides the electrical circuits within the module, so that shading of part of the panel by a chimney, skylight, or antenna does not prevent the entire module from functioning, but only its portion. When combined with an inverter with MPPT (Maximum Power Point Tracking) or power optimizers, this allows for a significant reduction in the typical energy losses associated with such installations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-me-132bd-640w-660w-sc-11-5-ver25-9-1-3058749c170a.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, lighter, -0.6 pp | | [AE Solar AE ME-132 645W](https://comparepv.com/panel/ae-solar-ae-me-132-645w) | 645 W | -15 W, lighter, -0.5 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +145 W, cooler, +3.8 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +140 W, cooler, +3.6 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +135 W, cooler, +3.5 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +130 W, cooler, +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, cooler, +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-132bd-660 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
