Middle of its segment, modest efficiency
The AURORA Pro series sets a new standard for efficiency through the use of advanced N-Type TOPCon cell technology, which minimizes energy loss and significantly increases module efficiency. This solution effectively eliminates the problem of light-induced degradation, translating into stable power production for decades. These panels are characterized by an excellent temperature coefficient, which means they operate effectively even on hot days when traditional modules lose power. Thanks to its innovative construction, this series offers a higher yield per square meter, which is crucial for investors with limited roof space. AURORA Pro is an ideal choice for demanding residential and commercial installations, where maximizing investment profitability and a short payback period are what matters most. A distinguishing feature of the series is its exceptional resistance to extreme weather conditions and increased efficiency in low light, which in the Polish climate guarantees real profits even on cloudy days. It is an option for those seeking a technological advantage over standard P-Type solutions, ensuring superior system operation and a longer linear performance warranty, which effectively protects the investor's capital for years.

The N-type TOPCon cells in the AURORA Pro series exhibit a temperature coefficient of Pmax of -0.31%/°C, a notably better result than typical P-type PERC modules (-0.35 to -0.40%/°C). In practice, this translates to 5–10% higher energy yield on hot summer days when module temperature exceeds 50–60°C.
The manufacturer guarantees degradation of ≤1% in the first year and ≤0.4%/year in subsequent years, resulting in ≥87.4% of nominal power after 30 years. Standard P-type PERC modules from leading suppliers (JA Solar, Trina) typically offer a 25-year warranty with output declining to ~84.8%, making EGing's warranty genuinely more advantageous for investors calculating long-term IRR.
The bifacial construction enables energy harvesting from light reflected off the ground surface (albedo). With typical ground albedo values of 0.2–0.3 (light gravel, EPDM membrane), the bifacial gain amounts to 5–15% annually, significantly improving LCOE in ground-mount or flat-roof installations without increasing the system's footprint.
EGing PV appears on the official BNEF Tier-1 PV Module Manufacturers list (confirmed at least since Q2 2024), enabling non-recourse project financing for utility-scale solar farms and supporting higher asset valuations upon potential resale. The company has been operating since 2003 and holds a manufacturing capacity of >25 GW per year.
Eleven power variants spanning 600–685 Wp allow precise string sizing to match inverter requirements (MPP voltage, Isc) across both residential rooftop systems and commercial or utility-scale projects, eliminating the need for additional resistors or power converters.
The series peaks at 22.05% efficiency, while comparable 210 mm TOPCon modules from Solarspace (SS9-66HD) and Seraphim (Sable) reach 22.21% at 690 Wp. The 0.16 percentage-point gap translates to approximately 0.7% lower yield per unit area — a meaningful disadvantage in space-constrained rooftop installations where every cm² contributes to revenue.
- Efficiency of 21.6% is 1.2pp below the TOPCon 600-650W median (22.8%)
- 215.5 W/m² power density is 12.2 W/m² below TOPCon 600-650W median (227.7 W/m²) - requires larger installation area
- Temperature coefficient of -0.30%/°C matches the TOPCon 600-650W median
- Weight of 35.0 kg is 2.3 kg above TOPCon 600-650W median (32.7 kg) - verify structural support
- 100% bifaciality enables rear-side power generation, boosting yield by 5-15% on reflective surfaces
