Warranty pick, no clear weak spot
AE Solar AURORA AE MD-144BD series photovoltaic panels represent an advanced solution for demanding investments, combining Bifacial Double Glass technology with the high efficiency of monocrystalline cells. The use of a bifacial design allows for efficient energy harvesting not only from direct sunlight but also from light reflected off the ground, which significantly increases the total annual energy yield. A key advantage of this series is the application of gallium-doped technology, which effectively eliminates the negative impact of light-induced degradation (LID), ensuring exceptional parameter stability for decades. Thanks to the 144 half-cut cell structure, the modules show less susceptibility to the negative effects of shading and are characterized by reduced resistive losses, which translates into better performance in difficult weather conditions. This product is primarily dedicated to solar farms and large commercial installations, where maximizing power density and a fast return on investment are of key importance. The robust construction based on double glass guarantees full resistance to ammonia corrosion and salt mist, which sets this series apart from the competition, especially in demanding industrial and agricultural environments. By choosing the AURORA series, investors gain the highest level of fire safety and mechanical durability that goes far beyond market standards.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
Top 25% of the PERC 550-600 W segment, against a median of 27 yrs.
According to the BloombergNEF Global PV Module Bankability 2024 report, AE Solar ranked 18th out of 67 evaluated manufacturers and is the only Tier-1 European supplier with a "high bankability" rating (50% in 2024 vs 26% in 2023). This translates to easier financing of PV farm projects by banks and infrastructure funds.
The bifacial design with 70±5% bifaciality allows for energy generation from both sides of the module, utilizing reflected light from the ground surface. In ground-mounted installations on reflective surfaces (gravel, concrete), the achievable additional gain ranges from 5–15% per year, compared to equivalent monofacial modules.
Doping with gallium in P-type PERC cells effectively neutralizes the LID (Light-Induced Degradation) phenomenon, which is typical of conventional boron-doped cells. The manufacturer guarantees the stability of the parameters throughout the 30-year power warranty period, distinguishing this series from standard PERC modules without gallium doping.
The module's efficiency, at 21.31% (in the 550 Wp variant), is practically identical to that of direct competitors: Goldi Solar GS10-B144-TF (21.3%), IBC Solar 182M Half Cell (21.28%), and S-Energy SL65-72BGJ (21.3%). The series maintains its power density compared to its peers, which is crucial when space is limited.
The frame-less construction and double-pane glass provide certified resistance to ammonia and salt mist corrosion (according to IEC 61701 and IEC 62716). This is a significant advantage for installations in agricultural, coastal, and industrial areas, where conventional aluminum-framed modules require more frequent replacement.
The manufacturer offers a 15-year product warranty (materials and workmanship), while the current market standard for Tier 1 modules is 25 years (e.g., Trina Solar, JA Solar, Longi). In the event of mechanical damage or delamination after the 15-year warranty period, repairs or replacements will be the sole responsibility of the investor.
In 2025-2026, N-type TOPCon technology became the dominant standard in the 500 Wp and above solar panel segment. TOPCon modules offer bifaciality exceeding 80% (compared to 70% for the previous generation), a lower annual degradation rate (~0.4% vs ~0.45-0.5% for PERC), and improved temperature coefficients. This translates into a measurable reduction in cumulative energy yield over a 30-year warranty period.
- Efficiency of 21.3% matches the PERC 550-600W median
- Power density of 213.1 W/m² matches the PERC 550-600W median
- At -0.35%/°C, hot weather performance is typical for PERC 550-600W panels
- 70% bifaciality enables rear-side power generation, boosting yield by 4-10% on reflective surfaces
- Ranked #8503 out of 14005 panels for efficiency in the database
