The use of **N-type TOPCon cells** helps minimize power losses over time and improves the module's performance at higher temperatures, which translates to more predictable energy yields in the Polish climate. The **bifacial** design allows for the utilization of reflected light from the ground, enabling the installation to "harvest" additional energy, for example, on a light-colored roof, gravel, or in a ground-mounted system. Another key advantage is the **dual-glass** construction, which increases resistance to moisture, micro-cracks, and material aging, a common issue with cheaper panels using traditional backsheets. The series is suitable for C&I and PV farm projects, as well as for demanding prosumers who expect **high durability and better performance in partially shaded conditions**, as well as long-term cost-effectiveness. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 550-600W\*\* median - At 218.7 W/m², this panel generates 5.7 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - Weight of 32.7 kg is 1.5 kg above \*\*TOPCon 550-600W\*\* median (31.2 kg) - verify structural support - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### How do N-type TOPCon cells in the VSUN75N-144BMH-DG differ from standard PERC cells? N-type TOPCon cells have lower first-year degradation and degrade more slowly over subsequent years compared to cheaper P-type PERC cells. The VSUN75N-144BMH-DG reaches up to 22.26% efficiency and a power temperature coefficient of -0.30%/°C, meaning smaller output losses on hot days compared to older-generation modules. In practice, this translates into higher and more stable energy yields throughout the system's operating life. ### How much extra energy does a bifacial VSUN75N-144BMH-DG installation produce compared to a standard panel? The bifacial design captures part of the light reflected off the surface beneath the array. The actual gain depends on ground albedo and mounting height - on light-colored gravel or white roofing with ground-mount installations, you can expect several to over a dozen percent more annual energy than from a monofacial panel of the same 575 Wp rating. On a typical pitched roof with dark shingles, the bifacial gain will be much smaller. ### What warranty covers the VSUN75N-144BMH-DG series and what does it include? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing a minimum of 87.4% of initial power output by the end of that period. This exceeds the standard 25-year terms offered by many manufacturers, which matters when calculating long-term ROI over several decades. ### Is the dual-glass VSUN75N-144BMH-DG heavier and harder to install on a pitched roof? Yes, the dual-glass construction brings module weight to around 32.7 kg at dimensions of 2278x1134x35 mm, more than a typical backsheet panel. This requires a sturdier mounting structure and verifying roof load capacity beforehand, especially on older buildings. In return, users get better resistance to moisture ingress, microcracks, and laminate aging, which matters given the wide temperature swings common in the Polish climate. ### Is VSUN a Tier 1 manufacturer, and is it trustworthy for a 30-year investment? VSUN Solar is not currently on the Bloomberg NEF Tier 1 list, though it is headquartered in Germany and manufactures panels using TOPCon technology also used by leading producers. Tier 1 status mainly reflects financial standing and bankability scale, not product quality itself. Given a warranty as long as 30 years on power output, it's worth confirming local warranty service availability with your distributor before purchase. ### How does the VSUN75N-144BMH-DG perform in low temperatures and frost? Solar panels, including the VSUN75N-144BMH-DG, actually operate more efficiently in cooler conditions than in summer heat, since electrical efficiency rises as ambient temperature drops - the power temperature coefficient here is -0.30%/°C. This means that below the 25°C reference temperature, the module delivers relatively more power than on a hot day, which is beneficial in the Polish climate, especially during spring and autumn. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/648924121169b-6-081758b21876.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.2 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.2 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.2 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.1 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [VSUN VSUN535-144MH](https://comparepv.com/panel/vsun-vsun535-144mh) | 535 W | Lighter, -1.4 pp, -5 yr warranty | | [VSUN VSUN540-144MH](https://comparepv.com/panel/vsun-vsun540-144mh) | 540 W | Lighter, -1.2 pp, -5 yr warranty | | [VSUN VSUN545-144MH](https://comparepv.com/panel/vsun-vsun545-144mh) | 545 W | Lighter, -1.0 pp, -5 yr warranty | | [VSUN VSUN550-144BMH](https://comparepv.com/panel/vsun-vsun550-144bmh) | 550 W | Hotter, lighter, -0.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, lighter, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +80 W, lighter, +2.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +75 W, lighter, +2.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +70 W, lighter, +2.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/vsun-vsun565n-144bmh-dg 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.
