Suntech Ultra V Pro mini (Transparent Black Glass-Glass Bifacial Module) are modules designed for installations where aesthetics, durability, and real energy yield matter. What sets them apart is the Transparent Black finish - an elegant, cohesive visual design easily adaptable to modern roofs and architectural projects compared to traditional panels with contrasting grid lines. The glass-glass construction with thin glass panels enhances moisture and micro-crack resistance while simultaneously reducing roof load - a key advantage for older roof structures and lightweight coverings.

N-type TOPCon cells help minimize performance degradation over time and maintain efficiency under typical rooftop operating conditions. The half-cut technology increases resilience to partial shading (chimneys, window frames, antennas), translating to more stable energy production. Thanks to the bifacial design, the module can harness reflected light, making it ideal for bright roofs, facades, carports, and ground-mounted systems where high albedo provides additional gain.

About the Ultra V Pro mini (Transparent Black Glass-Glass Bifacial Module) series

6 answered

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

How much power does the Suntech Ultra V Pro mini deliver and who is it suited for?
The module reaches a maximum power output of 440 Wp, allowing high energy yield from a limited roof area with fewer panels. Thanks to N-type TOPCon cells and bifacial construction, it works well for both residential rooftop installations and ground-mount or carport projects, where the extra gain from reflected light adds real value.
What's the difference between the bifacial technology in the Ultra V Pro mini and a standard monofacial panel?
A bifacial module generates electricity from both the front and rear side, capturing light reflected off the roof, facade, or bright ground surfaces. In practice this means additional energy yield, especially noticeable on light-colored surfaces, ground-mount systems, or elevated mounting structures, compared to conventional monofacial panels.
What warranty comes with the Suntech Ultra V Pro mini panels?
The manufacturer provides a 25-year product warranty and a 30-year linear power output warranty. This means that even after three decades of use, the panel should still deliver a significant share of its original power output, supporting a predictable long-term return on investment.
Is the glass-glass construction of the Ultra V Pro mini heavier and does it require roof reinforcement?
No, despite having two glass layers, the glass-glass module uses thinner glass than traditional glass-backsheet designs, keeping the weight increase minimal. This makes the panel safe for older roof trusses and lightweight roofing, while also improving resistance to moisture ingress and microcracks compared to standard construction.
Does the Transparent Black design suit modern homes without compromising performance compared to classic panels?
Transparent Black offers a uniform black finish without a visible grid pattern between cells, blending better with modern architecture than panels with a contrasting frame. The aesthetic doesn't affect electrical performance - the module still uses TOPCon cells, half-cut technology, and bifacial construction, so it retains full energy efficiency.
How do TOPCon cells and half-cut technology affect performance under partial shading?
Half-cut technology splits cells into smaller segments, so shading part of the panel (for example from a chimney or antenna) has less impact on the output of the entire module. N-type TOPCon cells also degrade more slowly over time, together resulting in more stable and predictable energy yield throughout the panel's service life.
