Product Overview
N-Type bifacial technology allows energy generation from both the front and rear of the module. In suitable installation conditions such as ground-mounted arrays, light-coloured roof surfaces, or flat roof systems with reflective material, the bifacial gain can increase total energy output by 5% to 25% compared to a standard monofacial panel of the same rated power.
The dual glass construction replaces the conventional back-sheet with a second glass layer, improving resistance to environmental stress and reducing long-term degradation. Combined with the low annual power loss of 0.40% from year 2, this module retains strong output well into the second decade of service.
The ET-NR66TBH625GL uses SMBB (Super Multi Busbar) cell technology to improve light trapping and current collection, contributing to the high efficiency figure. The panel also demonstrates excellent anti-PID performance through optimised manufacturing processes.
Applications
- Commercial rooftop solar installations
- Ground-mounted utility and agricultural solar arrays
- Warehouse and industrial building rooftop PV systems
- Flat roof installations with reflective surfaces
- Large residential solar projects
Installation and Safety Notes
This panel must be installed by a qualified MCS-accredited solar installer. Mounting structure design, cable sizing, string voltage calculations, and earthing must comply with IET Wiring Regulations and the panel manufacturer's installation instructions. Maximum system voltage is 1500VDC. Do not exceed the maximum series fuse rating of 30A.
