The use of half-cut cells reduces the risk of hot spots and minimizes internal resistance losses, resulting in more reliable energy production even under partial shading or in installations exposed to uneven sunlight. The series also features **high reliability, confirmed by IEC-compliant tests**, as well as refined soldering quality, which supports long-term, trouble-free operation. The modules feature **anti-reflective glass**, allowing them to better utilize light in less ideal conditions, such as cloudy weather. Finally, the series offers **robust mechanical resistance**, which is important in the Polish climate (wind, snow). The VDS-S120/FNH series is suitable for home prosumer installations, small businesses, and renovation projects, where a reasonable balance between efficiency, durability, and predictability is key. ## Notable figures - At 19.2% efficiency, this panel is 2.6pp below the \*\*database\*\* median of 21.8% - At 192.6 W/m², this panel generates 25.5 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - Temperature coefficient of -0.34%/°C is 0.04pp worse than \*\*database\*\* median (-0.30%/°C) - higher losses in summer heat - At 19.0 kg, this panel is 7.5 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - In the top 92% for efficiency among all N-type panels ## Questions ### What is the maximum power output of the VDS-S120/FNH panel and what installations does it suit? Panels in the VDS-S120/FNH series reach a maximum power output of up to 345 Wp. Thanks to PERC technology and half-cut cell design, they work well for residential rooftop installations, small businesses, and retrofit projects where stable energy output at a reasonable budget matters. ### Is the VDS-S120/FNH series still available for purchase? No, the VDS-S120/FNH series has been discontinued and is no longer offered as a new product. Availability is limited to remaining distributor stock. When planning a new installation or expanding an existing system, it's worth checking VDS Renewable's current lineup for replacement models with similar specifications. ### What warranty covers the VDS-S120/FNH panels and what does it include? The manufacturer provides a 12-year product warranty and a 25-year power output warranty. The product warranty covers material and workmanship defects, while the power warranty guarantees a specified performance level over time, which is important when calculating the long-term return on investment of the installation. ### What benefits do half-cut and PERC technology bring to the VDS-S120/FNH panels? Splitting cells into halves (half-cut) reduces the risk of hot spots and lowers internal resistance losses, resulting in more reliable performance under partial shading, such as from chimneys or antennas. PERC technology further increases light-to-energy conversion efficiency, improving yield especially in lower-light conditions. ### Are the VDS-S120/FNH panels bifacial and do they generate power from both sides? No, the VDS-S120/FNH series consists of monofacial panels (not bifacial). This means energy is generated only from the front side of the module, which is the standard solution for most rooftop installations where the rear side has no access to reflected light. ### Is the VDS-S120/FNH a Tier 1 panel, and does that matter when choosing modules? VDS Renewable is not listed as a Tier 1 manufacturer under the Bloomberg NEF classification, indicating a smaller financial scale and shorter market track record than the largest industry players. This doesn't directly affect module quality, but it's worth factoring into your assessment of long-term warranty support risk. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/325-345W-120cells-c10331ab6a1e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | Cooler, lighter, +4.1 pp | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | Cooler, lighter, +4.1 pp | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, +4.1 pp, +5 yr warranty | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +3.9 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +3.9 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | Lighter, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA182M300W](https://comparepv.com/panel/gamko-new-energy-gka182m300w) | 300 W | Lighter, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | Lighter, +3.8 pp, +5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +3.8 pp, +5 yr warranty | | [VDS Renewable VDS-S120/FNH-330W](https://comparepv.com/panel/vds-renewable-vds-s120-fnh-330w) | 330 W | +0.3 pp | | [VDS Renewable VDS-S120/FNH-335W](https://comparepv.com/panel/vds-renewable-vds-s120-fnh-335w) | 335 W | +10 W, +0.6 pp | | [VDS Renewable VDS-S120/FNH-340W](https://comparepv.com/panel/vds-renewable-vds-s120-fnh-340w) | 340 W | +15 W, +0.9 pp | | [VDS Renewable VDS-S120/FNH-345W](https://comparepv.com/panel/vds-renewable-vds-s120-fnh-345w) | 345 W | +20 W, +1.2 pp | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +115 W, cooler, +3.7 pp | | [Jetion JT435SYk(B)](https://comparepv.com/panel/jetion-jt435syk-b) | 435 W | +110 W, cooler, +3.5 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | +75 W, +3.4 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/vds-renewable-vds-s120-fnh-325w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
