Thanks to **bidirectional energy conversion**, they can better utilize reflected light from the ground, which helps to increase power generation where traditional "single-sided" panels leave potential untapped. The use of **half-cut technology** minimizes losses and improves performance under partial shading, while **MBB technology** supports higher efficiency and better resistance to microcracks in daily operation. In practice, the VDS-S144/M6H-BG solves common problems for farms and roofs in challenging operating conditions - temperature fluctuations, stronger winds, higher loads, and the risk of accelerated laminate aging. The **glass-glass** design promotes long-term durability, and the **high-sealing junction box** helps maintain safety and reliability. It is a good choice for commercial, industrial, and ground-mounted installations where predictable performance and durability are more important than just paper specifications. ## Notable figures - At 19.7% efficiency, this panel is 2.1pp below the \*\*database\*\* median of 21.8% - At 197.6 W/m², this panel generates 20.5 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 28.5 kg, this panel is 2.0 kg heavier than the \*\*database\*\* median (26.5 kg) - more demanding for installation crews - Bifaciality factor of 70% can add 4-10% extra yield with reflective mounting surface ## Questions ### Are VDS-S144/M6H-BG panels still available for purchase? No, the VDS-S144/M6H-BG series has been discontinued. Modules may still be available from distributors as remaining stock, but the manufacturer no longer guarantees continuous supply for new, larger projects. When planning an installation, confirm the availability of a specific batch and consider current replacement models with similar specifications. ### How do bifacial VDS-S144/M6H-BG panels differ from standard single-sided panels? Bifacial panels capture not only direct sunlight but also light reflected from the ground and reaching the rear side of the module. Thanks to the glass-glass construction and transparent backsheet, the VDS-S144/M6H-BG can generate additional energy from reflections, especially over bright surfaces, gravel, or snow. In practice this results in higher annual yield than classic backsheet panels of similar surface area. ### What warranty comes with VDS-S144/M6H-BG modules? VDS Renewable provides a 12-year product warranty covering material and workmanship defects, plus a 30-year power output warranty guaranteeing a minimum generation level over that period. These are standard terms for modern bifacial modules, though since this series is discontinued, warranty service may involve longer lead times. ### Does the 450 Wp VDS-S144/M6H-BG panel require a special mounting structure? The glass-glass construction is heavier than backsheet panels, so it requires a sturdy mounting system rated for the higher load, particularly on flat roofs or ground-mount installations. For bifacial setups, east-west racking or elevated frames are recommended to allow light exposure to the rear side, maximizing the bifacial gain. ### How do half-cut and MBB technology work in VDS-S144/M6H-BG panels, and is it worth it? Half-cut means cells are split in half, reducing resistive losses and improving performance under partial shading, such as from a chimney or leaves. MBB (multi busbar) technology increases the number of current-carrying paths, boosting conversion efficiency and lowering the risk of microcracks. Together these technologies deliver higher and more stable energy yield throughout the system's operating life. ### What types of installations are best suited for VDS-S144/M6H-BG panels? This series was designed for commercial, industrial, and ground-mount installations where wind resistance, temperature fluctuations, and long-term laminate durability matter. The glass-glass construction and high-sealing junction box perform well under demanding conditions, such as large solar farms or industrial roofs exposed to greater mechanical loads. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/430-450W-166-144cells-bifacial-68d5fad5c46f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | Cooler, lighter, +4.4 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | Cooler, lighter, +4.4 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +4.3 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, lighter, +4.3 pp | | [VDS Renewable VDS-S144/M6H-BG-435W](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-435w) | 435 W | +0.3 pp | | [VDS Renewable VDS-S144/M6H-BG-440W](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-440w) | 440 W | +10 W, +0.5 pp | | [VDS Renewable VDS-S144/M6H-445](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-445) | 445 W | +15 W, lighter, +0.8 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +160 W, +4.1 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +155 W, +3.9 pp, +5 yr warranty | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +150 W, cooler, +3.8 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +150 W, +3.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-430w Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
