Bifacial Panel 630W TOPCon Rectangular
Sunpro Power SPDG630-N132R12 bifacial module, 630 Wp with rectangular N-Type TOPCon R12 cells, 132 half-cut cells, bifaciality of approximately 80%. 25-year product and performance warranty. Format for commercial and utility-scale systems.
The Sunpro Power SPDG630-N132R12 photovoltaic module is a high-power 630 W bifacial panel, built with rectangular N-Type TOPCon cells in R12 format and a 132 half-cut cell configuration. The rectangular cells, larger than standard M10/M12 cells, make it possible to achieve module efficiency of around 23%, among the highest in the Sunpro Power range.
Why choose a 630W module with rectangular cells?
A high-power module reduces the number of panels required for the same installed kWp, with advantages in terms of mounting structure, wiring and installation labor costs. TOPCon technology with R12 rectangular cells declares bifaciality of around 80% (ratio between rear and front efficiency), higher than the average of PERC or BC modules from the same manufacturer.

Who is a module of this format suitable for?
At 2,38 meters long, the module is designed mainly for commercial and utility-scale systems, where the larger size per panel is offset by fewer modules to handle and wire. On residential installations with small roofs or irregular roof slopes, it may be less practical than the more compact formats in the same Sunpro Power range.
What does the supply include?
- SPDG630-N132R12 bifacial photovoltaic module with MC4 connectors
- IEC, PID certifications and salt mist/ammonia corrosion testing
Frequently asked questions
What is the difference between rectangular cells and standard M10/M12 cells?
R12 rectangular cells have a larger surface area than standard square M10/M12 cells, making it possible to achieve higher power per module and greater conversion efficiency, around 23% in this model.
Is the module suitable for a standard residential roof?
It must be assessed on a case-by-case basis: at 2,38 meters long and weighing 32,4 kg, it requires sufficiently large roof slopes and a support structure sized for the greater weight and overall dimensions compared with 440-500W modules.
What does 80% bifaciality mean?
It indicates that the efficiency of the rear side of the module is equal to 80% of that of the front side: the higher the bifaciality, the greater the expected energy contribution from the rear on installations with good albedo.
Is it certified for areas with heavy snow load?
Yes, the module is tested for a front load of up to 5.400 Pa, a value higher than the standard of many modules on the market, suitable for areas with significant snowfall.
How much power does it lose over time?
The performance warranty declared by the manufacturer covers 25 years, in line with the latest standards for high-end N-Type TOPCon modules.
