Middle of its segment, needs the roof space
The Aurora ME-120 series is an advanced solution based on Gallium-doped cell technology, which effectively eliminates the problem of light-induced degradation (LID). Thanks to this, the modules maintain the highest performance for decades, providing a key advantage over standard silicon components. The use of Half-Cut Cells design allows for better system performance in partial shading conditions and a reduction of resistive losses within the panel. For the investor, this means more stable energy yields even in less favorable weather. These panels stand out for their exceptional resistance to extreme mechanical loads, making them an ideal choice for Polish climatic conditions, characterized by strong winds and heavy snow. Aurora ME-120 is a solution for demanding residential and commercial users seeking maximum reliability and an aesthetic installation appearance. The use of innovative materials makes the modules resistant to salt corrosion and ammonia, extending their application to coastal areas and farms. By choosing this series, you are investing in system longevity and energy security based on proven German engineering, which sets standards in durability and quality of workmanship.

According to the BNEF 2024 report, AE Solar is the only European manufacturer with a high bankability rating (increasing from 26% in 2023 to 50% in 2024), which makes it easier to secure project financing and reduces the credit risk for institutional investors.
The manufacturer offers a full 30-year warranty, both for the product and for its power output, while the industry standard offered by comparable suppliers (e.g., Trina Solar, JA Solar) is 25 years. The extended warranty directly reduces the project's risk over the long term.
Replacing boron with gallium eliminates light-induced degradation (LID), which is typical for standard PERC cells. The module maintains its specified power output from the very beginning, without the characteristic performance drop in the first year of operation that is associated with boron.
Independent laboratory tests conducted by Kiwa PVEL awarded the Aurora series the "Top Performer" title for 2025, confirming the quality and reliability of the product, as well as the accuracy of its specifications compared to those listed in the product datasheet.
Certified compliance with IEC 61701 (salt spray) and IEC 62716 (ammonia) allows for installation in coastal areas and agricultural settings without the risk of accelerated enclosure and cell degradation.
The maximum efficiency of the series is 21.23%, while direct competitors in the same power range achieve 23.2% (Tongwei TWMND N-type) and 23.23% (Lexron TOPCon). This means that approximately 9% more module surface area is required to achieve the same installed power.
Market forecasts indicate a decline in the share of PERC technology at a CAGR of -10.8% between 2025 and 2030, with TOPCon technology expected to dominate (60% share by 2030). The choice of PERC in 2026 could limit the long-term viability of installations, and the higher annual degradation rate (0.6-0.8%/year vs 0.4-0.5%/year for TOPCon) would result in significant revenue losses over a 30-year period.
The panel is monofacial, while the competitor, Tongwei TWMND, in the same 580-600 W range offers bifacial N-type modules. When installed over a reflective surface (gravel, snow, white membrane), bifacial modules generate an additional 10-20% of energy without increasing the occupied surface area.
- Module efficiency of 20.5% is 1.9pp below average for TOPCon 550-600W panels (median: 22.4%)
- 205.2 W/m² power density is 19.2 W/m² below TOPCon 550-600W median (224.4 W/m²) - requires larger installation area
- Temperature coefficient of -0.34%/°C is 0.05pp worse than TOPCon 550-600W median (-0.29%/°C) - higher losses in summer heat
- Weight of 29.0 kg (2.2 kg below TOPCon 550-600W median of 31.2 kg) allows easier transport and roof mounting
- Ranked #11325 out of 14129 panels for efficiency in the database
