- 15-year product warranty and 30-year linear power warranty for long-term project planning.
DMEGC 630W N-type bifacial double glass solar panel
The DMEGC DM630G12RT-B66HSW is a 630 W N-type monocrystalline bifacial solar panel with a double-glass construction. It is designed for larger rooftop and ground-mounted arrays where high module output can help reduce the number of panels, mounting components and DC connections needed for a given installed capacity.
The transparent double-glass module can generate from both sides when installed in suitable conditions. Rear-side yield depends on site-specific factors such as mounting height, spacing, shading, ground reflectivity and the system layout, so this should be assessed during project design.
Key features
- 630 W rated output: Suitable for high-capacity solar arrays on commercial roofs, agricultural buildings, logistics facilities and ground-mounted installations.
- N-type bifacial technology: N-type monocrystalline cell construction with 132 cells in a 6 × 22 arrangement.
- Double-glass module: 2 mm heat-strengthened glass on both the front and rear of the panel.
- High-load capability: Rated for 5,400 Pa front-side and 2,400 Pa rear-side maximum test loads.
- Long-term warranty: 15-year product warranty and 30-year linear power warranty, with stated first-year degradation of no more than 1% and annual degradation of no more than 0.4% thereafter.
Where to use
The DMEGC 630W N-type bifacial solar panel is suitable for commercial and industrial rooftops, warehouses, logistics sites, factories, agricultural buildings, solar carports and ground-mounted solar PV projects. It is particularly suited to systems designed around larger-format, high-power modules.
At 2,382 mm long and 32.3 kg per panel, this module requires a mounting system designed for its dimensions, weight, frame profile and approved clamping zones. A structural assessment and installation by a competent solar installer are recommended.
Energian can help specify compatible inverters, mounting systems, DC protection, cabling and balance-of-system equipment. For complete solar installations, we can support project delivery through trusted installation partners.
