The AE Solar AURORA MD-108 (Mono-facial PV module) consists of a 108 mono-crystalline cells in PERC technology, along with a half-cut design, which focuses on stable energy production under typical Polish installation conditions - even with frequent cloud cover and diffuse light. The use of an advanced cell architecture helps minimize losses and improve efficiency, even when the roof has less-than-ideal exposure or experiences periodic shadows.

In practice, its key features include high resistance to LID degradation combined with a well-designed module, which translates into predictable performance over the years and a better return on investment. Another advantage is resistance to PID, which is important in systems operating at higher system voltages.

The AURORA MD-108 is well-suited for residential and commercial installations, particularly where long-term reliability, resistance to environmental conditions, and seamless integration with popular inverters are important. The mono-facial design makes it a good choice where reflection from the ground is not a factor, and a reliable output and durability are the priorities.

What owners get
The only European Tier-1 asset, according to BNEF

AE Solar is the only European manufacturer classified by BloombergNEF as a Tier-1 bankable company (Q1 2025). The bankability ratio increased from 26% in 2023 to 50% in 2024, which confirms the financial credibility of the manufacturer and reduces the risk for banks financing the installation.

30-year product and performance warranty

The manufacturer offers both a 30-year product warranty and a 30-year performance warranty (≥87.4% after 30 years, degradation ≤0.4%/year). The industry standard is a 10-15 year product warranty and a 25-year performance warranty, so the terms of the AURORA MD-108 significantly exceed those of the competition, including all three comparable products (Aptos, LEDVANCE, and Sunova) with a typical 25-year warranty.

Efficiency of up to 21.28% - among the best in its segment

Variant 415 W achieves an efficiency of 21.28%, slightly outperforming all three comparable products (Aptos DNA 108-Monofacial, LEDVANCE M415, Sunova TS-BG54 X), which all maintain a level of 21.25%. In the same price and technological category (PERC, 108 cells, half-cut), this is a significant advantage.

Gallium-doped wafers - lower LID

The use of PERC cells doped with gallium instead of standard boron eliminates the main LID (Light-Induced Degradation) mechanism, which is responsible for power loss in the early years of operation. When combined with a 182 mm half-cut architecture, it also reduces losses due to partial shading.

Environmental resistance (IP68, PID, corrosion resistance)

The module has certified resistance to PID, salt corrosion, ammonia, sand, and hail (IP68 rating). This is particularly important in Poland for installations near agricultural fields (ammonia) and in coastal areas (salt), where environmental conditions can shorten the lifespan of less robust modules.

Trade-offs
PERC Technology in the Market

TOPCon has surpassed 65% market share in global solar panel production in 2024 (compared to ~20% for PERC) and exhibits lower annual degradation rates (~0.25-0.4%/year vs ~0.5-0.7%/year for PERC). It is projected that PERC will be completely phased out of the market by around 2028 (CAGR -10.8% between 2025 and 2030), which could mean reduced availability of parts and service in the second half of the 30-year lifespan.

About the AURORA MD-108 (Mono-facial PV module) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is the warranty on AE Solar AURORA MD-108 panels?
The AURORA MD-108 series comes with a 30-year product warranty and a 30-year linear warranty on power output. For three decades, the manufacturer has guaranteed both the mechanical and electrical performance of the module, as well as the minimum energy yield. This is an exceptionally comprehensive warranty, comparable to those offered by leading Tier 1 brands - and AE Solar falls into this category.
What does the Ga-doped PERC technology in the AURORA MD-108 mean, and why does it limit LID degradation?
PERC cells doped with gallium instead of traditional boron exhibit significantly lower light-induced degradation (LID). In practice, the module loses less efficiency even in the first few weeks of operation, after installation. The more stable energy output from day one directly translates to a better return on investment over a 20-30 year lifespan.
What are the dimensions and weight of the AE Solar AURORA MD-108 panel, and does it fit on a typical sloped roof?
The AURORA MD-108 panel measures 1724 × 1133 × 35 mm and weighs 21.5 kg. These dimensions are standard in the prosumer segment - the module easily fits on a typical roof structure with standard rail spacing and does not pose any difficulties during installation on a pitched roof. Ten such panels cover approximately 19.5 m² of roof area.
Does the AURORA MD-108 produce sufficient power under cloudy and diffuse lighting conditions in Poland?
Yes. The half-cut module, consisting of 108 cells divided in half, reduces internal resistance and improves performance under partial shading or cloud cover, which is typical for the Polish climate. The PERC technology enhances the absorption of weaker, diffused radiation, which translates into better performance, especially during the autumn and winter months when sunlight intensity is low.
Will the AE Solar AURORA MD-108 panels withstand strong winds and hail, which are typical weather conditions in Poland?
AURORA MD-108 modules can withstand wind loads up to 2400 Pa and mechanical loads up to 5400 Pa, meeting the requirements for residential construction with a safety margin. They are also resistant to hail with stones up to 25 mm in diameter traveling at a speed of 23 m/s. The certified sealing of the joint is IP68, which protects the electrical components from moisture throughout their lifespan.
What power and efficiency does the top-of-the-line AE Solar AURORA MD-108 model achieve, and how many panels do I need for a home installation?
The most efficient panel from the AURORA MD-108 series achieves a peak power of 415 Wp with a module efficiency of 21.25%. The series includes variants ranging from 395 W to 415 W. For a typical residential installation with a power of 6 kWp, 15 panels of 400 W or 14-15 panels of 415 W would be sufficient. With dimensions of 1724 × 1133 mm, this would occupy approximately 27-28 m² of roof space.
