This listing covers 6 x ET Solar ET-NR66TBH625GL 625W N-Type bifacial dual glass solar panels, supplied strapped on a single pallet. Combined output across the six panels is 3750W (3.75kW), suitable for commercial, agricultural, industrial and ground-mounted solar PV projects.

625W bifacial solar panel features

• Cell technology, N-Type mono-crystalline bifacial cells, generating power from both the front and rear side of the panel.
• Module efficiency, 23.1%.
• Construction, dual glass design with 2.0mm front and 2.0mm rear glass, replacing the traditional backsheet.
• Bifacial gain, 5% to 25%, depending on installation conditions, with rear-side contribution up to approximately 115W per panel in suitable reflective installations.
• Junction box, IP68 rated with 3 bypass diodes, maximum system voltage 1500VDC.
• Warranty, 12 year product and workmanship warranty, 30 year linear power output warranty.

Applications

The dual glass build and N-Type cells suit installations where long service life and consistent output matter: commercial rooftops, agricultural sheds, ground-mounted arrays and industrial buildings. Six panels on one pallet make this a practical quantity for a small array or as part of a larger install.

Getting the rear-side gain

Bifacial panels only generate extra output from the rear cells if light can reach them. Installed at around 20° to 35° with clearance behind the panel and a reflective surface underneath, such as white gravel, painted concrete or a light membrane, the rear side adds to the front-side output. Mounting the panel flat against a dark or solid surface blocks this effect entirely, so ground-mounted frames, flat roof systems and open-frame carports work best.
