The use of N-type cells effectively eliminates the problem of light-induced degradation (LID), which translates into a significantly longer lifespan and stable energy production for decades. Thanks to the **Half-Cut design**, these panels perform excellently in partial shading conditions, minimizing power losses and protecting the system against the formation of hot-spots. A unique feature of this series is its aesthetics combined with high performance - the black frame and compact design make it an ideal choice for demanding users who care about the appearance of their roof. A **low temperature coefficient** guarantees that the installation maintains maximum efficiency even on hot summer days, which clearly distinguishes it from older P-type solutions. This product solves the problem of limited mounting space, offering high power density from every square meter of surface area. It is a solution dedicated to **modern prosumer installations** and commercial projects, where a fast return on investment and the reliability of Tier-1 class components are key. Investing in this series ensures the use of the latest achievements in materials engineering, providing excellent module performance in low sunlight conditions. ## Notable figures - At 22.0% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 220.2 W/m² matches the \*\*TOPCon 400-450W\*\* median - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - Ranked #6329 out of 14005 panels for efficiency in the database ## Questions ### What is the difference between N-type TOPCon technology in the VSUN N-108BMH-BB and older P-type panels? N-type TOPCon cells used in the N-108BMH-BB series virtually eliminate light-induced degradation (LID), which causes P-type panels to lose power output in their first years of operation. As a result, the module maintains higher efficiency over its entire lifespan, with a much more linear and predictable power degradation curve than older P-type technologies. ### Are VSUN N-108BMH-BB panels bifacial, and how much extra energy does that produce? Yes, the N-108BMH-BB series uses bifacial construction, generating power from both the front and rear side of the module. The rear side captures light reflected from the ground, roof, or a bright surface, and under favorable mounting conditions (e.g., light-colored roof, elevated racking) can increase annual energy yield by up to several percent compared to a monofacial panel of the same rated power. ### What warranty does the VSUN N-108BMH-BB series come with? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty guaranteeing sustained high performance throughout the system's operational life. This warranty structure is typical for modern N-type modules and supports long-term investment planning compared to older PV technologies. ### Is the VSUN N-108BMH-BB suitable for small pitched roofs with limited space? Yes, with power output up to 430 Wp and a compact half-cut cell layout, the series delivers high power density per square meter, which matters on pitched roofs with limited surface area. The half-cut design also reduces losses from partial shading, such as from chimneys or antennas, a common issue on residential roofs with complex geometry. ### How does the VSUN N-108BMH-BB perform in high summer temperatures? Thanks to N-type TOPCon technology, the series has a low power temperature coefficient, meaning less efficiency loss as the module heats up on hot days compared to conventional P-type panels. In practice, this results in more stable energy production during summer, when panel surface temperatures can exceed 60°C and older technologies lose proportionally more power. ### Is VSUN a Tier-1 manufacturer, and is it reliable for a large investment? VSUN is not currently on the BloombergNEF Tier-1 list, but the company operates a European hub in Germany, and its modules go through standard quality certifications and industry-standard reliability testing. Tier-1 status mainly reflects a manufacturer's financial bankability rather than technical module quality, so purchasing decisions should be based on warranty terms and technical specifications rather than this classification alone. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/663b24984a851-699441c62a21.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +2.1 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +2.1 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +2.0 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, +2.0 pp | | [VSUN VSUN390-108BMH-DG](https://comparepv.com/panel/vsun-vsun390-108bmh-dg) | 390 W | -40 W, heavier, -2.1 pp | | [VSUN VSUN395-108BMH-DG](https://comparepv.com/panel/vsun-vsun395-108bmh-dg) | 395 W | -35 W, heavier, -1.8 pp | | [VSUN VSUN400-108BMH-DG](https://comparepv.com/panel/vsun-vsun400-108bmh-dg) | 400 W | -30 W, heavier, -1.5 pp | | [VSUN VSUN405-108BMH-DG](https://comparepv.com/panel/vsun-vsun405-108bmh-dg) | 405 W | -25 W, heavier, -1.3 pp | | [VSUN VSUN410-108BMH](https://comparepv.com/panel/vsun-vsun410-108bmh) | 410 W | -20 W, hotter, -1.0 pp | | [VSUN VSUN415N-108MH](https://comparepv.com/panel/vsun-vsun415n-108mh) | 415 W | -15 W, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +80 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +65 W, cooler, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +70 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +70 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/vsun-vsun430n-108bmh-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.
