The use of a 120 half-cut cell structure combined with TOPCon architecture allows for a significant reduction in resistive losses and better performance in low-light conditions. What distinguishes these modules is primarily **minimal light-induced degradation** (LID) and an excellent temperature coefficient, thanks to which the installation produces more energy on hot days. These panels are dedicated to investors seeking **maximum self-consumption** with limited roof space, in both the residential and commercial sectors. Compared to traditional solutions, the N-120MH series offers a longer lifespan and stability of parameters for decades, which directly translates into a faster return on investment. The solid frame construction and high resistance to mechanical loads guarantee safety in difficult weather conditions. By choosing these modules, the user receives **energy stability** based on the latest achievements in materials engineering, which effectively eliminate typical problems of older cell generations. This solution is an ideal choice for demanding prosumers for whom the **highest operational performance** of the module throughout the year, regardless of the weather, is what matters. ## Notable figures - At 21.7% efficiency, this panel is 0.8pp below the \*\*TOPCon 450-500W\*\* median of 22.5% - 217.2 W/m² power density is 8.0 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - requires larger installation area - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - Ranked #7399 out of 14005 panels for efficiency in the database ## Questions ### What is TOPCon cell technology used in the VSUN N-120MH panels, and how does it differ from classic PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that reduces recombination losses through an additional passivation layer on the rear side of the cell. Compared to older P-type PERC cells, TOPCon delivers higher efficiency (up to 21.7%), lower light-induced degradation (LID), and better long-term parameter stability. The N-120MH series uses 120 half-cut cells, which further reduces resistive losses and improves module performance under partial shading. ### What warranty comes with the VSUN N-120MH panels, and what does it cover? The manufacturer provides a 25-year product warranty and a 30-year power performance warranty, guaranteeing at least 87.4% of nominal power output by the end of that period. First-year power degradation is capped at 1%, dropping below 0.4% annually thereafter. This warranty structure ensures the installation maintains high energy productivity throughout its service life, directly improving the return on investment. ### Are VSUN N-120MH panels suitable for roofs with limited space? Yes. With maximum power reaching 470 Wp and efficiency up to 21.7%, the N-120MH panels deliver higher installed capacity from fewer modules than older PERC-based designs. This makes them especially useful on sloped roofs with limited surface area, where maximizing self-consumption without enlarging the mounting area is the priority. ### Is the VSUN N-120MH a bifacial panel that generates power from both sides? No, the N-120MH series consists of monofacial panels that generate power only from the front side of the module. Despite lacking dual-side generation, the TOPCon architecture combined with half-cut cells still delivers strong efficiency and parameter stability, making these panels a versatile choice for both rooftop and ground-mounted installations without needing special light-reflecting structures. ### How do VSUN N-120MH panels perform on hot days and in high temperatures? The N-120MH panels have a favorable power temperature coefficient of around -0.3%/°C, better than typical PERC modules (usually -0.35% to -0.4%/°C). This means a smaller power drop as cell temperature rises above 25°C, resulting in higher energy yield on hot, sunny days — common on well-exposed rooftops during Polish summers. ### Is VSUN a Tier 1 manufacturer, and where are the N-120MH panels made? VSUN does not currently appear on the Bloomberg NEF Tier 1 manufacturer list, but the company operates a European headquarters in Germany, which supports warranty handling and logistics across the Polish and EU markets. Lacking Tier 1 status doesn't directly reflect module quality — buyers should focus on technical specifications, warranty terms, and local service availability when choosing panels. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/661e0d8c2edf3-1-629d83733026.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +40 W, cooler, +3.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +35 W, cooler, +3.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +30 W, cooler, +2.8 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +30 W, cooler, +2.8 pp | | [VSUN VSUN455N-120MH](https://comparepv.com/panel/vsun-vsun455n-120mh) | 455 W | -15 W, -0.7 pp | | [VSUN VSUN460N-120BMH-DG-BB](https://comparepv.com/panel/vsun-vsun460n-120bmh-dg-bb) | 460 W | -10 W, heavier, -0.5 pp | | [VSUN VSUN465N-120BMH-DG-BB](https://comparepv.com/panel/vsun-vsun465n-120bmh-dg-bb) | 465 W | Heavier, -0.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +90 W, cooler, +3.1 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +85 W, cooler, +2.9 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +80 W, lighter, +2.7 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +70 W, cooler, +2.7 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +70 W, cooler, +2.7 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +75 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +75 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/vsun-vsun470n-120mh Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
