The use of **PERC** technology helps to better utilize solar radiation, which translates into more reliable performance even when solar conditions are not ideal. A key advantage is the design based on **144 cells**, which promotes even distribution of loads and makes it easier to design chains in popular inverters. The module has a **positive power tolerance**, meaning that its actual performance is often closer to the declared specifications than to reducing them. In practice, this means fewer disappointments after installing the system and better predictability of energy yields. The **robust construction** with tempered glass with an anti-reflective coating and a sealed junction box also adds to its appeal, reducing the risk of problems in rain, snow, and with large temperature fluctuations. This is a sensible choice for investors who want a proven series without paying extra for features that don't always provide real value. ## Notable figures - At 20.1% efficiency, this panel is 1.7pp below the \*\*database\*\* median of 21.8% - At 201.3 W/m², this panel generates 16.8 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.34%/°C temperature coefficient - 0.04pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - Weight of 23.0 kg (3.5 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - Ranked #12102 out of 14005 panels for efficiency in the database ## Questions ### Is the VDS Renewable VDS-S144/FNH series still available for purchase? The VDS-S144/FNH series has been discontinued and is no longer part of the manufacturer's current production lineup. Availability is now limited to remaining distributor stock. Anyone planning an installation should confirm current stock with their supplier, and if unavailable, consider a newer model with comparable specifications from the manufacturer's current catalog. ### What warranty comes with the VDS-S144/FNH panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 25-year power performance warranty guaranteeing limited cell degradation over time. These are standard terms for monocrystalline PERC panels in this class, though since production has ended, warranty support depends on the manufacturer's service availability in a given country. ### How does the PERC technology used in the VDS-S144/FNH differ from standard monocrystalline panels? PERC technology adds a passivation layer to the back of the cell that reflects unused light back into the silicon structure. This lets the cell capture more of the available light, especially in low-light conditions such as early morning, evening, or overcast weather. In practice, this results in higher efficiency and more stable energy output compared to older panels without this layer. ### What is the maximum power output of the VDS-S144/FNH, and what installations is it suited for? The panel reaches a maximum power output of 410 Wp, making it a solid choice for both single-family homes and smaller commercial installations on flat or pitched roofs. Its 144-cell layout helps distribute string voltage evenly, so it pairs well with popular inverter models commonly used on the market. ### Are the VDS-S144/FNH panels bifacial? No, the VDS-S144/FNH series is a monofacial panel, not bifacial. It generates power only from the front surface. For rooftop installations where the rear side has no access to reflected light anyway, this design is fully sufficient and typically more cost-effective than a bifacial equivalent. ### Do the VDS-S144/FNH panels hold up well in harsh weather, such as heavy snow loads or strong wind? Yes, the modules use tempered glass with an anti-reflective coating and a sealed junction box, improving resistance to moisture, rain, and temperature fluctuations. This construction reduces the risk of microcracks and internal connection corrosion, though for regions with heavy snow loads it's worth double-checking the maximum mechanical load rating in the datasheet. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/390-410W-158-144cells-b3039605510b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +50 W, cooler, +3.2 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +50 W, cooler, +3.2 pp | | [Yingli YL455CF54 e/2](https://comparepv.com/panel/yingli-yl455cf54-e-2) | 455 W | +50 W, cooler, +3.2 pp | | [Einnova Solarline ESM-455T](https://comparepv.com/panel/einnova-solarline-esm-455t) | 455 W | +50 W, +3.2 pp, +5 yr warranty | | [SunEvo Solar SE5-54HBC-455W](https://comparepv.com/panel/sunevo-solar-se5-54hbc-455w) | 455 W | +50 W, cooler, +3.2 pp | | [Just Solar JST-EDMH-(445-465)W-TD (455W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-455w-class) | 455 W | +50 W, +3.2 pp, +5 yr warranty | | [Luxor Solar LX-455M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-455m-182r-96-gg) | 455 W | +50 W, cooler, +3.2 pp | | [VDS Renewable VDS-S144/FNH-390W](https://comparepv.com/panel/vds-renewable-vds-s144-fnh-390w) | 390 W | -15 W, -0.7 pp | | [VDS Renewable VDS-S144/FNH-395W](https://comparepv.com/panel/vds-renewable-vds-s144-fnh-395w) | 395 W | -10 W, -0.5 pp | | [VDS Renewable VDS-S144/FNH-400W](https://comparepv.com/panel/vds-renewable-vds-s144-fnh-400w) | 400 W | -0.2 pp | | [VDS Renewable VDS-S144/FNH-410W](https://comparepv.com/panel/vds-renewable-vds-s144-fnh-410w) | 410 W | +0.3 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Cooler, +3.9 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +3.6 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | Cooler, +3.4 pp, +15 yr warranty | | [MY Solar MS480NC-HJTPBFT](https://comparepv.com/panel/my-solar-ms480nc-hjtpbft) | 480 W | +75 W, cooler, +2.0 pp | | [LG LG440QAC-A6](https://comparepv.com/panel/lg-lg440qac-a6) | 440 W | +35 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/vds-renewable-vds-s144-fnh-405w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
