The industry standard offered by most manufacturers is typically a 12-15 year product warranty and a 25-year power warranty (e.g., Aptos Solar DNA-108 - 25 years), making this series stand out in the market. - **Superior performance compared to direct competitors** - The maximum efficiency of the module is 21.28%, while the three directly comparable series - Aptos Solar DNA-108, LEDVANCE M395~415P54LM-BF-F3, and Sunova TS-BG54 - achieve 21.25%. The difference is minimal, but it confirms that the series is among the best in the 108-cell module PERC segment. - **Top Performer: Kiwa PVEL 2025** - The AURORA series has been recognized as a Top Performer in the 11th edition of the Kiwa PVEL PV Module Reliability Scorecard (2025), which provides independent verification of the module's reliability in thermal cycling, humidity, and PID/LID+LETID degradation tests. This award is given to only 50 manufacturers from the global market. - **POE encapsulation + dual-glass, 1.8 mm thick** - Using POE film instead of standard EVA, combined with a 1.8 mm tempered glass, minimizes UV degradation, thermal cycle losses, and moisture absorption. According to the manufacturer's data, this translates to a lower risk of delamination and micro-cracks compared to glass-film modules, particularly in tropical and desert climates. - **Tier 1 BNEF - 16th consecutive qualification** - AE Solar has been included in the Tier 1 list of BloombergNEF for the 16th time (as of Q1 2025), which is a prerequisite for banks to finance PV projects under non-recourse financing models. This means that for project developers and investors, it is easier to access project finance without the need for additional due diligence from the supplier. ## Cons - **PERC technology, not TOPCon** - By 2025-2026, TOPCon is expected to replace PERC as the industry standard. TOPCon solar cells achieve a bifaciality rate of approximately 85%, compared to 70±5% in the AURORA MD-108BD series, along with a better temperature coefficient (~-0.30%/°C vs. -0.35%/°C), which, under typical installation conditions in Poland (module temperature exceeding 40°C in summer), could result in a 2-4% lower annual energy yield compared to an equivalent TOPCon module. - **Weight: 22.5 kg - assembly limitations** - The dual-glass construction results in a module weighing 22.5 kg, which is approximately 2.5-3.5 kg more than comparable glass-film modules in this power range. For older, sloped roofs or industrial halls with limited load-bearing capacity, a structural assessment is required before installation, which adds an additional cost for the investor. ## About this series The AE Solar AURORA MD-108BD (bifacial double-glass) series is designed to significantly improve energy yield in environments where performance under variable conditions is critical. The **double-glass** construction enhances resistance to environmental factors and stabilizes the module's parameters over the long term, while also minimizing the risk of micro-cracks during operation. Thanks to **bifacial technology**, the panel can also utilize reflected light from the ground - a feature particularly beneficial for installations on flat roofs, light membranes, carports, and PV farms. The use of **half-cut PERC monocrystalline** cells improves performance under partial shading and reduces resistive losses, helping to maintain production during morning hours and cloudy conditions. Another key feature is the use of **POE** film, which supports the durability of the laminate structure. This is a series for investors who expect predictable performance, high resilience, and a better energy balance without compromising the design. ## Notable figures - 20.3% module efficiency - 0.8pp better than the \*\*PERC 0-400W\*\* median of 19.4% - 202.6 W/m² power density - 8.4 W/m² more than \*\*PERC 0-400W\*\* median (194.2 W/m²), more power per roof area - Temperature coefficient of -0.35%/°C matches the \*\*PERC 0-400W\*\* median - At 23.5 kg, this panel is 3.0 kg heavier than the \*\*PERC 0-400W\*\* median (20.5 kg) - more demanding for installation crews - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### What actual benefits do I gain from using bifacial panels like the AE Solar AURORA MD-108BD in terms of energy production? The bifacial technology in the AURORA MD-108BD series allows for additional energy generation from the back side of the module, which - according to the manufacturer's data and independent tests - ranges from 3% to 10% depending on the type of substrate and installation conditions. The best results are achieved on bright surfaces: white flat roof membranes, gravel, concrete, or ground-mounted PV farms with lighter coverings. The bifacial effect is minimal on dark roof tiles. ### What warranty does AE Solar offer for the AURORA MD-108BD series? The manufacturer provides a 30-year warranty on the product (material warranty) and a 30-year linear power warranty. This exceptionally long warranty period - rarely seen in the market - reflects the manufacturer's confidence in the glass-on-glass construction with POE film, which effectively protects the laminate from moisture and degradation. AE Solar is a German-based brand, classified as Tier 1 manufacturer, which provides additional assurance regarding warranty fulfillment. ### Is the AE Solar AURORA MD-108BD panel suitable for a flat roof or carport? Yes, the AURORA MD-108BD series is particularly recommended for installation on flat roofs and carports. The double-pane glass-glass construction provides high mechanical strength and does not require a rear foil, which is important when installed horizontally or at a slight angle. The bifacial technology further enhances performance in these locations - a clear membrane or a light-colored parking surface reflects light onto the back of the module, increasing energy yield. ### How does the AURORA MD-108BD perform under partial shade conditions? The use of PERC monocrystalline cells in a half-cut configuration (108 cells divided into two independent halves) significantly reduces losses caused by partial shading. Each half of the module operates independently - shade on one part does not affect the operation of the other. This is a key advantage in urban installations, where chimneys, antennas, or nearby buildings can cast shadows on part of the roof. ### What is the weight of the AE Solar AURORA MD-108BD panel, and will a typical roof structure be able to support it? The AURORA MD-108BD module weighs 25.5 kg with dimensions of 1721 x 1133 x 30 mm. This is slightly more than standard glass-foil panels, which is due to its double-pane construction. Most typical steel and aluminum roof structures on pitched and flat roofs can easily handle this load. However, it is advisable to verify the roof's load-bearing capacity with a structural engineer before installation, especially for older buildings or when using a large number of modules. ### What differentiates the AE Solar AURORA MD-108BD series from standard monofacial panels with a rear-side film? Key differences include: firstly, double-sided glass instead of film - this increases resistance to moisture, sand, and hail, and extends the lifespan of the module. Secondly, bifacial technology allows for light to be collected from both sides, which monofacial modules cannot do. Thirdly, POE film instead of standard EVA improves the long-term stability of the laminate. In return, the panel is heavier and usually more expensive, but it offers higher efficiency and longer warranties. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ae-md-108bd-395w-415w-sc-11-5-ver25-9-1-228da07b4693.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +45 W, cooler, +2.8 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -35 W, lighter, +2.7 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | -15 W, lighter, +2.7 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.7 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.7 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | -15 W, lighter, +2.7 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +45 W, cooler, +2.6 pp | | [Luxor Solar LX-440M/182-108+](https://comparepv.com/panel/luxor-solar-lx-440m-182-108) | 440 W | Cooler, +2.6 pp, -5 yr warranty | | [AE Solar AE CMD-72BD 280W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-280w) | 280 W | -115 W, cooler, -5.9 pp | | [AE Solar AE CMD-72BD 285W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-285w) | 285 W | -110 W, cooler, -5.6 pp | | [AE Solar AE CMD-72BD 290W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-290w) | 290 W | -105 W, cooler, -5.4 pp | | [AE Solar AE CMD-72BD 295W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-295w) | 295 W | -100 W, cooler, -5.1 pp | | [AE Solar AE CMD-72BD 300W](https://comparepv.com/panel/ae-solar-ae-cmd-72bd-300w) | 300 W | -95 W, cooler, -4.9 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +115 W, cooler, +4.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +100 W, cooler, +4.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +110 W, cooler, +4.4 pp | --- Source: https://comparepv.com/panel/ae-solar-md-108bd-395w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
