625W N-Type Bifacial Dual Glass Solar Panel Pack of 2 | ET Solar

This listing covers 2 x ET Solar ET-NR66TBH625GL 625W N-Type bifacial dual glass solar panels, giving a combined output of 1,250W. Each panel reaches 23.1% module efficiency and carries a 30-year linear power output warranty, making the pair suited to commercial, agricultural and ground-mounted projects where output per panel matters.

625w bifacial solar panel features

• Power output, 625W per panel (STC), 1,250W combined for the pack
• Cell technology, N-Type mono-crystalline bifacial cells with SMBB busbar design
• Efficiency, 23.1% module efficiency
• Glass construction, dual glass, 2.0mm front and rear, in place of a back-sheet
• Bifacial gain, 5% to 25% additional yield depending on installation conditions
• Junction box, IP68 rated with 3 bypass diodes
• Degradation, first year max 1%, subsequent years max 0.40% per year

Dual glass and bifacial construction

N-Type bifacial cells generate energy from both faces of the module. On ground-mounted arrays, light-coloured roofs or reflective flat roof systems, the rear face adds 5% to 25% on top of the front-side rating. Replacing the back-sheet with a second glass layer improves resistance to environmental stress, and the panel is built for a maximum system voltage of 1500VDC with an operating temperature range of -40 to +85 degrees C. Power tolerance is 0 to +3%, and the module carries a 12-year product and workmanship warranty alongside the 30-year linear power warranty.

Applications

The ET-NR66TBH625GL is built for commercial rooftop installations, ground-mounted utility and agricultural arrays, warehouse and industrial rooftops, flat roofs with reflective surfaces, and large residential projects. Installation must be carried out by an MCS-accredited installer, with mounting structure, cable sizing, string voltage calculations and earthing carried out in line with IET Wiring Regulations and the panel's datasheet limits.
