DMxxxM10RT-B54HBT is a transparent, bifacial double-glass module in DMEGC Solar’s Infinity RT family. The xxx in the family name is replaced by the module’s nominal wattage, giving codes from DM440M10RT-B54HBT to DM460M10RT-B54HBT in the June 2025 datasheet.
Electrical and physical format
The five front-side standard test condition ratings run in 5 W steps from 440 W to 460 W. Their module efficiencies rise from 22.0% to 23.0%. Each uses 108 n-type monocrystalline cells in a 1762 by 1134 by 30 mm frame.
Two 2 mm heat-strengthened glass sheets form the front and rear covers. Light reaching the back of the panel can therefore contribute additional output, but that rear-side contribution is separate from the front-side nameplate rating. Bifaciality is 80% with a tolerance of five percentage points.
The maximum-power temperature coefficient is -0.29% per degree Celsius and the nominal module operating temperature is 42°C with a 2°C tolerance. These describe different effects: the coefficient shows how maximum power changes as cell temperature rises, while the operating-temperature figure is a defined test result rather than a maximum permitted temperature.
Exact code and MCS match
At 22 July 2026, current MCS records cover the 30 mm DM455M10RT-B54HBT and DM460M10RT-B54HBT as MR 50616791 0003/147 and 0003/148. Their certification period runs to 28 February 2029. Separate records exist for 35 mm frames and -L variants, so a partial family-code match is insufficient.
DMEGC’s Infinity RT 2.0 description still names M10RT, and its June 2026 N-type warranty includes M10RT constructions. The live product tiles and download centre now list G12RT codes rather than this M10RT sheet. This exact family is a supported, MCS-certified earlier format rather than a current catalogue model.
The B54HBT construction has a 25-year product warranty and a 30-year linear power warranty. The power schedule allows no more than 1% degradation in year one and 0.4% in each later year, leaving 87.4% at year 30. Detailed terms depend on the warranty version applicable to the supply date.
