Description Renesola RS9-720NBG-E1 Bifacial
Solar panel Renesola RS9-720NBG-E1 Bifacial
On large-scale sites — commercial rooftops, ground-mount plants, industrial facilities — the arithmetic is simple: the higher the power of a single module, the fewer units are needed per kilowatt. The Renesola RS9-720NBG-E1 Bifacial is the top performer of this line: 720 W nominal power at 23.18% module efficiency, one of the strongest results in the range. Its large 2384×1303 mm format and 38.7 kg weight are the price of that output, and it pays off through faster installation, fewer mounting points, shorter cable runs and a lower system cost per installed kilowatt.
N-type TOPCon and 132 half-cut cells
The module is built on 132 N-type TOPCon half-cells, the generation that has pushed classic P-type PERC out of the premium segment. N-type silicon avoids the light-induced degradation typical of older technology in the first months of operation: first-year power loss is capped at 1%, followed by a gentle 0.4% annual decline. After thirty years the panel still holds roughly 87.4% of its original output, and that figure is exactly what the thirty-year performance warranty covers.
Bifacial generation and glass-glass construction
The RS9-720NBG-E1 is a bifacial module — its rear side also generates, adding output from light reflected off the roof, ground or a light-coloured surface. The bifaciality factor is 80% ±5%, and on sites with reflective or light ground cover this bonus is clearly visible in the annual energy yield. A glass-glass build instead of the usual glass-backsheet adds resistance to moisture, potential-induced degradation (PID) and micro-cracks, while an IP68 rating and a -40°C to +85°C operating range make it suitable both for hot steppe regions and for harsh winter climates.
Engineering headroom for industrial projects
A maximum system voltage of 1500 V is the standard for commercial and industrial inverter setups, allowing longer strings and fewer combiner circuits — which means less cabling and switching gear overall. For EPC contractors calculating balance-of-system cost per installed megawatt, high-wattage 1500V-ready modules like this one are a direct way to cut the budget without sacrificing reliability.
In practice, installers working on commercial and industrial projects increasingly choose modules in this 700+ W power class: fewer units per project simplify logistics, shorten time spent on the roof or field, and reduce the chance of installation errors — especially valuable where the installation window is limited by weather or by a facility's production schedule.
Who it suits
The Renesola RS9-720NBG-E1 Bifacial fits ground-mounted solar plants, large commercial roofs and industrial sites where total power per square metre and per labour hour of installation matters. It also works well for a high-output private system when the owner wants to cover their energy demand with as few panels as possible.
If you are considering this module for your project, reach out to our managers — we will size the system for your roof or site and help select the inverter and mounting structure. The module is in stock, with fast delivery available.
