xElite Solar 625W N-Type Bifacial Dual Glass Solar Panels - Pallet of 6
This listing is for 6 x Elite Solar ET-NR66TBH625GL 625W N-Type bifacial dual glass solar panels, supplied packed and strapped on a pallet. The total combined output is 3750W, or 3.75kW, making this pallet ideal for commercial, agricultural, industrial and ground-mounted solar PV projects.
Each Elite Solar 625W panel is built with high-efficiency N-Type mono-crystalline bifacial cells, delivering 23.1% module efficiency and excellent long-term performance. The dual glass construction improves durability, weather resistance and protection against environmental stress, making the panels suitable for demanding installations where reliability is essential.
Bifacial Solar Technology and Albedo Gain
Unlike standard solar panels, bifacial solar panels are designed to generate electricity from both the front and the rear side of the module. The front side captures direct sunlight, while the rear side captures reflected light from the surface below the panel. This reflected light is known as the albedo effect.
The albedo factor depends on how much light the ground or mounting surface can reflect back onto the rear side of the solar panel. Dark surfaces such as black felt, soil or tarmac reflect very little light, so the rear-side gain will be lower. Light-coloured and reflective surfaces such as white gravel, white membrane, painted concrete, light-coloured ballast, reflective sheets or pale roof surfaces can significantly improve the rear-side generation.
When installed correctly at around 20° to 35° with good clearance behind the panel and a reflective surface underneath, the rear side of the panel can contribute additional output. Under suitable conditions, the rear-side gain can be up to approximately 115W per panel, although this depends on the installation angle, surface reflectivity, height from the ground, shading, spacing between rows and overall site conditions.
To benefit properly from bifacial technology, the back of the panel must not be blocked. The panel should not be installed flat against a dark or solid surface, as this will prevent reflected light from reaching the rear cells. Bifacial panels perform best on ground-mounted frames, flat roof mounting systems, carports, agricultural structures and open-frame installations where light can reach both sides of the module.

Product Overview
The Elite Solar ET-NR66TBH625GL is a high-output N-Type bifacial dual glass solar panel designed for installations where performance, reliability and long service life are important. With a 625W front-side rating and additional rear-side generation potential, this panel is a strong choice for projects where space is valuable and energy yield needs to be maximised.
N-Type cell technology offers improved efficiency, lower degradation and better long-term power retention compared with conventional solar cell technologies. This makes the panel suitable for commercial rooftops, agricultural solar systems, ground-mounted arrays, industrial buildings and large residential PV systems.
The dual glass design replaces the traditional backsheet with a second glass layer. This improves mechanical strength and helps protect the solar cells from moisture, UV exposure and environmental ageing. The result is a more robust panel with a longer operating life and stable performance across demanding outdoor conditions.
For best bifacial performance, the installation should allow reflected light to reach the rear side of the module. A raised mounting structure, correct tilt angle, good row spacing and a reflective surface underneath the panels will help increase the albedo gain. White gravel, white roof membrane, painted concrete or reflective ground covering can all improve the rear-side contribution.

- Use a reflective surface underneath the panels, such as white gravel, white membrane, painted concrete or reflective sheet material
- Keep the rear side of the panel open and unobstructed
- Avoid mounting the panel directly against dark surfaces
- Allow enough height and air gap behind the panel for reflected light to reach the rear cells
- Avoid rear-side shading from rails, cables, ballast blocks or nearby structures where possible
- Use suitable row spacing to reduce shading between panel rows
Installation and Safety Notes
These solar panels must be installed by a qualified solar installer. Mounting structure design, cable sizing, string voltage calculations, earthing, DC protection and inverter compatibility must comply with the IET Wiring Regulations and the manufacturer’s installation instructions.
The maximum system voltage is 1500VDC. Do not exceed the maximum series fuse rating of 30A. Correct handling is required during transport and installation, as dual glass panels must be supported properly to prevent stress or damage.
