Description Renesola RS9-705NBG-E1 Bifacial
Solar panel Renesola RS9-705NBG-E1 Bifacial
The real advantage of a bifacial module shows up not on a datasheet but on an actual site — wherever there is something for light to bounce off. The Renesola RS9-705NBG-E1 Bifacial, rated at 705 W with 22.71% module efficiency, has a rear cell surface that genuinely takes part in power generation, harvesting kilowatt-hours that a conventional one-sided panel simply loses.
How bifacial generation actually works
The bifaciality factor of the RS9-705NBG-E1 is 80% ±5% — meaning the rear side can add up to four-fifths of the front side's output under favourable conditions. The biggest gain comes from a light or reflective ground surface: gravel, concrete, a light-coloured roofing membrane, or in winter, snow cover, which partly offsets the shorter daylight hours. On ground-mount plants with a properly prepared base, this is a measurable, real addition to annual yield above the front-side rating.
132 N-type TOPCon half-cells
The module is built on 132 N-type TOPCon half-cells, a technology that has largely displaced P-type PERC from the top market segment. First-year degradation is capped at 1%, followed by 0.4% per year, and after 30 years the module still retains roughly 87.4% of its initial output — the figure covered by the manufacturer's thirty-year performance warranty.
Glass-glass construction and IP68 protection
For the rear side to genuinely generate rather than just exist, it is protected by tempered glass instead of a thin backsheet — a glass-glass build that is more resistant to moisture, potential-induced degradation and mechanical stress. The IP68 protection rating and -40°C to +85°C operating range allow the module to be used regardless of climate zone, and a 1500 V maximum system voltage matches current design standards.
The electrical parameters at maximum power point — 41.11 V and 17.15 A — fit comfortably into the range of medium and large string inverters, and the headroom under the 1500 V maximum system voltage gives the designer freedom to build longer strings without hitting a controller's limit.
Designers of ground-mount plants increasingly plan bifacial arrays specifically around light-coloured ground cover — gravel bedding or reflective membranes — deliberately raising the site's albedo for that extra percentage of generation. It is an investment that pays off across the plant's entire service life, not a one-off purchasing saving.
Who it suits
The Renesola RS9-705NBG-E1 Bifacial is particularly well suited to ground-mounted plants with a prepared light-coloured base, flat commercial roofs with light roofing, and sites in snowy regions where winter albedo partly compensates for the shorter daylight period.
Work with our specialists to estimate how much extra yield a bifacial layout would give on your specific site — we'll help pick the optimal mounting height and tilt angle for the best effect.
