Thanks to the use of **TOPCon** technology, these panels offer significantly lower annual degradation and higher energy yields compared to traditional P-type solutions. The **Bifacial Dual Glass** design allows for the efficient use of light reflected from the ground, which is crucial for installations on flat roofs or ground-mounted structures where every percent of additional power matters for the investment's profitability. The **Black-on-Black** aesthetics make these modules blend perfectly with modern architecture, eliminating compromises between appearance and functionality. Double tempered glass not only increases fire safety but also ensures exceptional **resistance to extreme weather conditions**, such as hail or strong winds, protecting the cells from micro-cracks for decades. This solution is dedicated to investors seeking maximum longevity and financial stability for their project. By choosing this series, the user receives a product highly resistant to PID and LID effects, which translates into a safe and stable return on investment over a long-term horizon. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 222.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - At 25.0 kg (3.0 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is the maximum power and efficiency of the VSUN N-96BMHR-DG-BB panel? The VSUN N-96BMHR-DG-BB series reaches up to 460 Wp with a module efficiency of around 23%. This is achieved through N-type TOPCon cells combined with multi-busbar (MBB) circular ribbon technology, which improves current collection and reduces resistive losses. For installations with limited roof space, this means higher total output than comparable P-type panels of similar dimensions. ### Is the bifacial VSUN N-96BMHR-DG-BB suitable for flat roofs or ground-mount installations? Yes, the Bifacial Dual Glass design of this series was built specifically for these applications. The rear side of the cells captures light reflected from bright surfaces, white gravel, or membrane roofing, which under good albedo conditions can add several percent to double-digit annual energy gains. This requires adequate mounting height and clearance beneath the module, so the best results come from ground-mount racks, carports, or east-west flat-roof systems. ### What warranty comes with the VSUN N-96BMHR-DG-BB panels? The manufacturer provides a 12-year product warranty against material and workmanship defects, plus a 30-year linear power output warranty ensuring strong energy production throughout that period. Thanks to TOPCon technology, annual degradation is lower than in P-type panels, resulting in higher real-world energy yield toward the end of the warranty period and more stable returns for commercial and ground-mount projects. ### How does the TOPCon technology in the VSUN N-96BMHR-DG-BB differ from traditional PERC cells? N-type TOPCon cells have an additional tunnel oxide passivation layer on the rear side, which reduces carrier recombination and increases efficiency compared to P-type PERC cells. In practice this means lower annual degradation, reduced sensitivity to PID and LID effects, and better performance at high temperatures and in low-light conditions. For an investor, this translates into higher yearly energy yield, especially on overcast days or at low sun angles. ### Do the VSUN N-96BMHR-DG-BB panels perform well in high summer temperatures? Yes, this series has a favorable power temperature coefficient of around -0.30%/°C, better than many P-type panels which show steeper losses. This means a smaller power drop as the module heats up on hot days, which matters for roofs with poor ventilation or in high-irradiance regions where panel surface temperatures can exceed 60°C. ### Does the double tempered glass and Black-on-Black frame on the VSUN N-96BMHR-DG-BB reduce panel performance? No, the Black-on-Black aesthetic results from a black rear glass and frame, not a change in cell technology, so electrical parameters are unaffected. Additionally, the double tempered glass (front and rear) increases mechanical resistance to hail and strong wind and improves fire safety class compared to standard backsheet panels. This combines a modern appearance with long-term structural durability, useful for visible facades or residential roofs. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/663b24adb2cb7-57391b5953ee.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, lighter, +2.2 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, cooler, +2.2 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, cooler, +2.0 pp | | [VSUN VSUN435N-96BMHR-DG-BB](https://comparepv.com/panel/vsun-vsun435n-96bmhr-dg-bb) | 435 W | -10 W, -0.5 pp | | [VSUN VSUN440N-96BMHR-DG-BB](https://comparepv.com/panel/vsun-vsun440n-96bmhr-dg-bb) | 440 W | -0.2 pp | | [VSUN VSUN450N-96BMHR-DG-BB](https://comparepv.com/panel/vsun-vsun450n-96bmhr-dg-bb) | 450 W | +0.2 pp | | [VSUN VSUN455N-96BMHR-DG-BB](https://comparepv.com/panel/vsun-vsun455n-96bmhr-dg-bb) | 455 W | +10 W, +0.5 pp | | [VSUN VSUN460N-96BMHR-DG-BB](https://comparepv.com/panel/vsun-vsun460n-96bmhr-dg-bb) | 460 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/vsun-vsun445n-96bmhr-dg-bb Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
