Suntech Ultra V Pro Mini (FULL-BLACK Glass-Glass MONOFACIAL) is a series designed for maximum energy output on limited roof space-without compromising aesthetics. The application of N-type TOPCon cells and the half-cut design helps minimize losses and improves module performance under partial shading, which has real significance on rooftops with chimneys, windows, or antennas. The key advantage of this series is the glass-glass structure-enhanced rigidity and weather resistance, along with better parameter stability over time compared to many glass-film panels.

The monofacial version is a suitable choice where bifacial capability isn't necessary (e.g., standard inclined roofs), and reliable operation is prioritized. The full-black finish facilitates seamless integration with modern roofing materials and premium designs while remaining a practical solution for residential and small commercial installations, where reliability, longevity, and high energy output per square meter are essential.

About the Ultra V Pro mini (FULL-BLACK Glass-Glass MONOFACIAL) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

Are Suntech Ultra V Pro mini FULL-BLACK panels suitable for a sloped residential roof?
Yes, this is one of the primary applications for this series. The glass-glass construction provides higher rigidity and better resistance to snow and wind loads than typical glass-backsheet panels, while the full-black finish blends well with dark roof tiles. The monofacial version performs predictably regardless of the color or texture of the roof surface beneath the panel.
How much power does one Suntech Ultra V Pro mini panel produce, and how many are needed for a 6 kW system?
Each panel reaches a maximum power output of 440 Wp. To build a system of around 6 kW, you would need approximately 14 modules (14 x 440 Wp = 6160 Wp). The exact number depends on available roof space, tilt angle, and inverter sizing determined by the system designer.
What warranty comes with Suntech Ultra V Pro mini panels, and how does it compare to other manufacturers?
The manufacturer offers a 25-year product warranty and a 30-year power performance warranty, which is above the market standard of 12-15 years for product coverage and 25 years for power output. This is enabled by the glass-glass construction, which better protects the cells from moisture ingress and degradation over time.
What's the difference between the monofacial and bifacial versions, and which should I choose for a home installation?
A monofacial panel generates energy only from its front side, while a bifacial panel also captures light reflected off the ground onto the rear surface. On a standard sloped roof, where the panel's backside has no access to light, bifaciality provides no real benefit - making the monofacial Ultra V Pro mini a more cost-effective choice with equal efficiency for this type of installation.
What advantage does N-type TOPCon technology offer over older P-type cells?
TOPCon cells deliver higher efficiency and lower power degradation in the first year and throughout subsequent years of operation compared to traditional P-type PERC cells. In practice, this means higher energy yield from the same roof area and more stable power output across the full 30-year power warranty period.
Does the glass-glass construction require special mounting hardware or a stronger roof structure?
Glass-glass panels are typically somewhat heavier than glass-backsheet panels, so this should be factored into the choice of mounting system, though it's generally not an issue for standard sloped roofs on single-family homes. Installation uses standard mounting rails compatible with the panel frame, and the added rigidity of the glass-glass design further improves resistance to mechanical damage.
