The DMEGC DM460G12RT-B48HBW is a 460 W N-type mono-crystalline solar module from DMEGC's Infinity RT range, built for installers who want high wattage per panel without compromising on roof aesthetics. It pairs a 108 half-cut cell layout with bifacial dual-glass construction and a clean black frame / white backsheet finish, making it equally suited to large commercial arrays and residential roofs where appearance matters.
With a class-leading 23.0% module efficiency, a 30-year linear power warranty, and rear-side energy gain from its bifacial design, this module is engineered to deliver more usable energy per square metre of roof space over a longer service life.

Dual-glass module
Informational: Rear-side gain figures (BNPI) shown in the spec table assume typical ground-reflective conditions; actual bifacial gain on site depends on mounting height, tilt, and ground surface albedo.
N-Type Mono-Crystalline Cells
Lower first-year and annual degradation than conventional P-type panels — DMEGC rates this module at ≤1% first-year and ≤0.4% annual degradation over 30 years.
108 Half-Cut Cell Design
96 full cells cut into 108 half-cells (6×16 layout) to reduce resistive losses and improve tolerance to partial shading.
Bifacial Dual-Glass Build
2 mm heat-strengthened glass on both front and rear enables rear-side power generation for additional energy yield.
Anti-Reflective Coating
Front glass coating improves light absorption across a wider range of incidence angles for better low-light performance.
High Mechanical Load Rating
Rated to 5,400 Pa snow load and 2,400 Pa wind load (design load), suiting exposed and high-altitude installations.
30-Year Linear Power Warranty
Guaranteed output of 87.4% of nominal power at year 30, backed by DMEGC's extended performance warranty.

Frequently Asked Questions
What does "N-type" mean and why does it matter?
N-type cells use a different base wafer doping than standard P-type panels, which gives them lower degradation rates over time — DMEGC specifies ≤1% in the first year and ≤0.4% annually thereafter, supporting the 30-year linear power warranty.
How much extra energy does the bifacial design generate?
The datasheet's BNPI rating shows output rising to 508 W under typical rear-illumination conditions (135 W/m² rear irradiance) versus 460 W at front-only STC. Real-world gain depends on mounting height, tilt angle, and how reflective the surface beneath the array is.
Is this module suitable for high snow-load or windy sites?
Yes. It carries a design load rating of 5,400 Pa (snow) and 2,400 Pa (wind), which is above typical UK requirements, though the specific mounting method affects the final rating — always check the installation manual.
What connector type does this module use?
It's fitted with Stäubli PV-KST4/KBT4-EVO2 series connectors on 4 mm² output cables, which are MC4-compatible and widely used across UK inverter and cable systems.
What warranty coverage applies to this panel?
DMEGC provides a 25-year product warranty and a 30-year linear power warranty, guaranteeing at least 87.4% of nominal output at year 30 — performance warranty terms apply to front-side (STC) output.
Can this module be used on both residential and commercial roofs?
Yes — the black frame and white backsheet give it a neutral, low-profile appearance suited to residential rooftops, while its high per-panel wattage and 1,500 V DC system voltage make it equally practical for larger commercial string arrays.
