DMEGC 635W Mono N-Type Bifacial Double Glass Solar Panels
- 635W rated front-side output and 23.5% module efficiency for high-capacity commercial, industrial and ground-mounted arrays.
- Bifacial construction can generate additional electricity where light reaches the rear surface.
- Double-glass module with a 15-year product warranty and 30-year linear power warranty, subject to DMEGC’s applicable terms.
DMEGC 635W N-type bifacial double glass solar panel
The DMEGC 635W N-type bifacial double glass solar panel provides high output per module for larger solar PV projects. The DM635G12RT-B66HSW combines 132 monocrystalline cells with 2mm heat-strengthened glass on both sides. Its 635W rating is measured under standard test conditions; any additional rear-side generation depends on the installation and available reflected light.
Key features
- 635W rated output and 23.5% module efficiency under standard test conditions.
- Bifacial N-type monocrystalline construction, with a stated bifaciality of 80% ±5%.
- 2mm front and rear heat-strengthened glass, with an IP68 junction box containing three diodes.
- Published test loads of 5400Pa front and 2400Pa rear, with separate design-load ratings of 3600Pa front and 1600Pa rear.
- 30-year linear power warranty showing 87.4% retained rated output at year 30, subject to warranty conditions.
Where to use
Suitable for professionally designed commercial and industrial rooftops, warehouses, logistics facilities, agricultural buildings, solar carports and ground-mounted arrays. Check handling access, roof layout and structural capacity for the 2382 × 1134mm module format and 32.3kg weight.
Bifacial generation depends on mounting height, rear shading, row spacing and ground or roof reflectivity. Bifaciality is not a guaranteed percentage increase in annual energy yield. Use mounting equipment approved for the exact module frame and fixing positions, with a structural assessment where required.
Energian can help with module quantities, bifacial-array layout, inverter string design, mounting compatibility and DC protection. Check inverter current limits against the final bifacial design conditions. This panel requires installation as part of a solar PV system; installation can be arranged through trusted partners.
