Space saver, no clear weak spot
The DMEGC INFINITY RT (DMxxxM10RT-B54HBT) series are panels designed for maximum rooftop energy production, without compromises on durability. The application of N-type TOPCon cells helps reduce degradation-related losses over time and maintains stable operation in the long term. In practice, this translates to better energy yield, especially in demanding weather conditions.
What sets these modules apart is the dual-glass construction and bifaciality - the panel can utilize reflected light from the substrate, which is significant on bright roofs, in breezes, carports, or when mounted on ground structures. The dual-glass structure improves environmental resistance and supports predictable performance over time.
The INFINITY RT series is also designed for real-world roofing scenarios: the Full Black aesthetics and black frame make it easy to match modern architecture, while high resistance to phenomena such as PID reduces the risk of power drops in high-voltage installations. This is an excellent choice for homeowners, businesses, and designers with limited space and high quality demands.
Ranking
Signals from the data
Residential, commercial and BIPV.
Top 20% of the TOPCon 450-500 W segment, against a median of 225.2.
Top 22% of the TOPCon 450-500 W segment, against a median of 22.52%.
The 22–23% efficiency range places the series among the strongest peer comparables: Risen RSM96-11 (23%) and SunKean SKT440~460M12 (23.02%), while remaining well above the Zonergy ZPM MH3-72 (21.16%). This translates to approximately 8% more energy from the same roof area compared to lower-performing competitors in the segment.
A Pmax/°C of -0.29% outperforms typical PERC modules (-0.35%/°C). Under Polish summer conditions — with modules reaching 65°C — this difference results in measurably higher yield during peak hours, estimated at 1.5–2% more energy than a PERC panel of equivalent nameplate power.
The manufacturer guarantees ≥87.4% of rated power after 30 years, with annual degradation ≤0.4% (first-year LID loss <1%). By comparison, standard PERC warranties in this segment cover 25 years with a floor of 84.8%. This represents approximately 5 additional years of coverage and a higher guaranteed power output throughout the entire system lifetime.
The dual glass design (2.0 mm / 2.0 mm) eliminates backsheet degradation risk and improves resistance to PID, moisture, and ammonia. The series carries an agrivoltaics certification (verified by VP Solar), expanding its application scope to ground-mount, carport, and agri-PV systems without the need for additional certification.
DMEGC Solar has maintained BNEF Tier 1 status for multiple consecutive quarters (confirmed Q3 2025), qualifying projects for non-recourse debt financing. Founded in 1980, the manufacturer operates 21 GW/year of production capacity — a strong assurance of supply continuity and warranty support for commercial installations.
The dual glass construction increases module weight to 24.5 kg, approximately 15–20% more than monofacial modules of comparable wattage (roughly 20–21 kg). For older buildings or rooftop structures with limited load-bearing capacity, an additional structural engineering assessment is required — a step that is rarely necessary with lighter single-glass alternatives.
- At 23.0% efficiency, this panel is on par with typical TOPCon 450-500W modules
- 230.2 W/m² power density - 5.0 W/m² more than TOPCon 450-500W median (225.2 W/m²), more power per roof area
- Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
- Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface
- In the top 14% for efficiency among all TOPCon panels
