The DMEGC INFINITY RT (DMxxxM10RT-B54HBB) series was designed with the goal of maximizing rooftop yield per square meter, without compromising on aesthetics. These are full black modules featuring a refined, uniform appearance, making them an excellent fit for modern architecture and premium developments. The application of N-type TOPCon cells ensures superior performance at high temperatures and more stable yields under low-light conditions-where conventional panels often significantly lose efficiency. The glass-glass construction enhances resistance to environmental factors and mechanical stress, offering a tangible advantage for rooftops exposed to wind, snow, and decades of daily exposure. Furthermore, bifacial technology allows for the utilization of reflected light (e.g., from a light-colored surface), helping to increase energy production in favorable conditions. This is the series for residential and commercial installations where high yield, longevity, and a distinctive appearance that sets the project apart from standard solutions are essential.

What owners get
Low Temperature Coefficient of Pmax

The N-type TOPCon cells deliver a Pmax temperature coefficient of -0.29%/°C, placing this series well ahead of typical PERC modules (-0.34 to -0.36%/°C). In the Polish climate, where module temperatures regularly exceed 60°C during summer, this difference translates into measurably higher energy yield during peak solar hours.

30-Year Power Warranty, Degradation ≤0.4%/Year

The manufacturer guarantees ≥87.4% of nominal power after 30 years, with annual degradation ≤0.4% and ≥99% retention after year one, confirmed by IEC TS 63342 LeTID certification. The peer-comparable Zonergy ZPM MH3-72 offers a standard 25-year warranty, making this series the warranty leader in the 440–460 Wp segment.

Premium-Class Efficiency: 22–23%

The efficiency range of 22–23% places this series on par with the strongest competitors in the comparison: Risen RSM96-11 (23%) and SunKean SKT440~460M12-96D4 (23.02%), and decisively above the Zonergy ZPM MH3-72 (21.16%). For rooftops with limited surface area, the 1.84 percentage point advantage over Zonergy translates into meaningfully more kWp without requiring additional square footage.

High-Strength Glass-Glass Construction

The dual 2 mm glass design provides certified mechanical resistance of 5,400 Pa on the front face (snow load) and 2,400 Pa on the rear (wind load), per IEC 61215. Additional certifications to IEC 61701 (salt mist corrosion), IEC 62716 (ammonia resistance), and IEC TS 63209 (extended-stress testing) make this series suitable for demanding exposure environments.

BNEF Tier 1, Bankability Confirmed in Q3 2025

DMEGC maintains uninterrupted BloombergNEF Tier 1 status, confirmed in Q3 2025, and is listed by S&P Global. Operating since 1980 with an annual manufacturing capacity of 21 GW, the company offers reliable module availability, eligibility for non-recourse debt project financing, and warranty service stability throughout the full 30-year guarantee period.

Trade-offs
Higher Module Weight (Glass-Glass)

The bifacial glass-glass variant weighs approximately 24.5 kg, compared to 20–21 kg for a typical glass-backsheet module of equivalent power output. For installations on older rooftops or lightweight steel structures, this necessitates a structural load assessment and may generate additional reinforcement costs or limit the number of modules that can be deployed in a given project.

Common questions

6 answered
What warranty applies to DMEGC INFINITY RT panels (DMxxxM10RT-B54HBB)?
The DMEGC INFINITY RT series comes with a 25-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. The manufacturer guarantees that after 30 years of operation the module will retain at least 87.4% of its original rated power, with a maximum annual degradation rate of 0.4% from the second year of operation onward. This is one of the longest power warranties available in the Tier 1 premium module segment.
What is TOPCon technology and why should it be chosen for the INFINITY RT series over standard PERC panels?
TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology. Compared to mainstream PERC cells, TOPCon exhibits a lower temperature coefficient, meaning reduced power losses on hot days, as well as superior performance under low-irradiance conditions — such as early morning, late evening, and overcast skies. This translates into a measurably higher annual energy yield from the same roof area.
Are DMEGC INFINITY RT panels suitable for aesthetically demanding residential installations?
Yes. The INFINITY RT series consists of full-black modules featuring a black frame, black cells, and a black rear glass in place of a white backsheet. The uniform dark appearance integrates seamlessly with contemporary architecture and roofs finished with black tiles or shingles. These modules are frequently specified in premium installations where visual integration with the building is considered just as important as system performance.
What are the benefits of the glass-glass construction in DMEGC INFINITY RT modules, and does it matter when selecting a panel?
Glass-glass construction means the module uses a tempered glass cover on both the front and rear sides instead of a conventional polymer backsheet. This provides significantly higher resistance to moisture ingress, UV radiation, and mechanical loads such as heavy snow accumulation and strong wind pressure. The service life of glass-glass modules is estimated at over 30 years, which represents a tangible advantage for installations exposed to variable and demanding weather conditions.
Does the bifacial technology in the INFINITY RT series genuinely increase energy production on a rooftop?
Bifacial technology enables the rear side of the module to generate additional energy from reflected irradiance. On flat roofs with a light-colored membrane or ground-mounted systems over a bright substrate, the production gain typically ranges from 5% to 15% per year. On a conventional pitched roof the effect is more modest; however, bifaciality still improves yield through diffuse light reflected from the surrounding environment and under overcast sky conditions.
What is the peak power output of the highest-rated panels in the DMEGC INFINITY RT DMxxxM10RT-B54HBB series, and which installations are they best suited for?
The DMEGC INFINITY RT series reaches a maximum power output of 460 Wp under Standard Test Conditions (STC). Variants are available in the 440–460 W range, allowing the module selection to be precisely matched to a given project's requirements. The high per-module power rating means a greater total installed capacity can be achieved from a limited roof area, making the series equally well suited for residential prosumer systems and commercial-scale projects.
