DMEGC 515W Mono N-Type Bifacial Double Glass Solar Panels
- 515 W N-type bifacial solar panel for high-output residential, commercial and industrial solar PV systems.
- 23.0% module efficiency with double 2 mm heat-strengthened glass and a 1,500 V DC maximum system voltage.
- Compact large-format design at 1,977 × 1,134 mm, backed by a 30-year linear power warranty.
DMEGC 515W N-type bifacial double glass solar panel
The DMEGC DM515G12RT-B54HBW is a 515 W N-type monocrystalline bifacial solar panel with double-glass construction. It offers a high module output in a 1,977 mm long format, making it suitable for projects where available roof or ground area needs to be used efficiently.
Its bifacial construction can generate electricity from both the front and rear of the module when installed in suitable conditions. Actual rear-side yield depends on the mounting height, array layout, shading and reflected light from the surface below the panels.
Key features
- 515 W rated output: Supports higher-capacity arrays with fewer modules, roof fixings and DC connections than lower-wattage alternatives.
- N-type monocrystalline cells: 108 cells in a 6 × 18 configuration with 23.0% module efficiency at STC.
- Bifacial double-glass construction: 2 mm heat-strengthened glass on the front and rear, with an anti-reflective front coating.
- High mechanical load rating: Maximum test load of 5,400 Pa on the front and 2,400 Pa on the rear.
- Long-term output cover: Stated first-year degradation of no more than 1%, annual degradation of no more than 0.4% over 30 years, and a 30-year linear power warranty.
Where to use
The DMEGC 515W N-type bifacial double glass solar panel is suitable for homes, commercial premises, warehouses, agricultural buildings, logistics facilities, carports and ground-mounted solar PV arrays. It is a practical choice where larger high-efficiency modules can reduce component count without moving to the largest utility-scale panel formats.
At 27.1 kg per panel, this module must be used with a mounting system approved for its dimensions, frame profile, loads and clamping zones. Check the roof structure and project wind and snow loads before installation.
Energian can help with panel quantities, string design, inverter selection, mounting compatibility, DC protection and complete system planning. Where a system cannot be used out of the box, installation can be arranged through trusted partners.
