The ET-NR66TBH625GL is a 625W N-Type bifacial dual glass solar panel from ET Solar, rated at 23.1% module efficiency with a 30-year linear power output warranty. It suits commercial, agricultural and ground-mounted arrays where high output and long service life both matter, pairing N-Type cell technology with a dual-glass build for demanding sites.

Key features of this 625W bifacial solar panel

• Peak power: 625W at STC.
• Cell technology: N-Type mono-crystalline, bifacial.
• Module efficiency: 23.1%.
• Glass construction: 2.0mm front and rear glass in place of a back-sheet.
• Bifacial gain: 5% to 25% depending on installation conditions.
• Junction box: IP68 with 3 bypass diodes.

Applications

Used on commercial rooftops, ground-mounted utility and agricultural arrays, warehouse and industrial roofs, flat roofs with reflective surfaces, and larger residential projects.

N-Type bifacial performance

Generating from both faces, the panel can add 5% to 25% extra output over an equivalent monofacial module in suitable conditions such as ground mounts, light-coloured roofs or reflective flat-roof surfaces. The dual glass layers replace the usual back-sheet, adding resistance to environmental stress alongside a low degradation rate from the second year onward.

Installation notes

Fit by a qualified MCS-accredited installer only. Maximum system voltage is 1500VDC and the maximum series fuse rating is 30A. Mounting structure design, cable sizing and earthing must follow IET Wiring Regulations and ET Solar's installation instructions.
