DMEGC DM515G12RT-B54HBW — specifications and benefits
- N-Type mono-crystalline cells: First-year degradation ≤ 1.00% and ≤ 0.40% per year thereafter — lower power loss at high cell temperatures compared to P-Type technology.
- Bifacial dual-glass architecture: Enhanced mechanical rigidity and PID resistance — additional rear-side energy yield dependent on reflection (albedo), mounting height and system design.
- Certified mechanical load rating: Tested to +5400 Pa front-side load and −3600 Pa rear-side load — contributes to enhanced resistance against mechanical stress and reduces the risk of microcracks.
- Long performance warranty: 30-year linear warranty with minimum 87.40% of original rated power can contribute to a lower Levelized Cost of Electricity (LCOE), depending on project design.

How much additional energy yield does the bifacial panel produce?
The additional energy yield of a bifacial solar panel depends on the reflectivity of the surface (albedo), the mounting height, the system configuration and the project location. The bifaciality factor of this model is 80% ± 5%. At an albedo of 10% the theoretical STC-equivalent rated power is approximately 567 Wp, at 20% approximately 618 Wp and at 30% approximately 670 Wp. The actual additional energy yield varies per installation and should be determined using a suitable PV simulation tool based on the specific project location.
Which inverters are compatible with the DMEGC DM515G12RT-B54HBW?
The module is compatible with PV string and hybrid inverters whose maximum input voltage, MPPT range and maximum input current are consistent with the electrical characteristics of this module (Voc 40.75V, Isc 15.83A, max. system voltage 1500V DC). This includes suitable string and hybrid inverters from manufacturers such as Solis, GoodWe, Huawei and SMA, provided the electrical specifications are compatible. Always refer to the inverter's technical specifications and this module's datasheet before installation to confirm electrical compatibility.
How does the performance warranty of the DMEGC DM515G12RT-B54HBW work?
DMEGC provides a 25-year product warranty and a 30-year linear performance warranty. First-year degradation is limited to ≤ 1.00%, followed by an annual degradation of ≤ 0.40%. This guarantees that the module will still deliver at least 87.40% of its original rated power after 30 years. The performance warranty applies to the front side (STC) — the official datasheet is the authoritative source for the full warranty terms.
What is the advantage of N-Type over P-Type solar panels?
N-Type solar cells use phosphorus as a dopant instead of boron (P-Type). This results in a lower first-year degradation (LID — Light Induced Degradation) of ≤ 1.00% in year one, compared to an average of 1.5–3% for P-Type panels. In addition, N-Type cells have a lower temperature coefficient (−0.29%/°C for this model), meaning they lose less power at higher cell temperatures than comparable P-Type panels. Over a period of 30 years, this can contribute to a higher total energy yield.
