The use of **Half-Cut Cells** technology allows for a significant reduction in internal energy losses, which proves crucial during hot days when traditional modules lose efficiency faster. Thanks to the division into two independent working sections, this series effectively solves the problem of partial shading, guaranteeing stable power production even with unfavorable roof positioning or periodic obstacles. The use of M6 type cells ensures optimal power density, making these modules an ideal choice for investors focusing on **maximum yield from limited mounting space**. The construction is characterized by reinforced resistance to mechanical loads, which, combined with multi-busbar technology, minimizes the risk of micro-cracks. This is a solution dedicated primarily to **extensive commercial installations** and solar farms, where long-term reliability and fast cost amortization are priorities. Compared to the competition, VDS-S144/M6H stands out with its excellent compatibility with modern inverters, and the **optimized temperature coefficient** makes these panels work more efficiently in the variable Polish climate, maintaining high efficiency over decades of use. ## Notable figures - Efficiency of 20.5% is 1.3pp below the \*\*database\*\* median (21.8%) - 204.4 W/m² power density is 13.7 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - -0.34%/°C temperature coefficient - 0.04pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - 23.8 kg weight - 2.7 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - #11308 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### Is the VDS-S144/M6H series still available for purchase? No, production of the VDS-S144/M6H series has been discontinued and the panels are no longer part of the manufacturer's current lineup. Availability is limited to remaining distributor stock. If you plan to expand an existing installation with additional identical modules, check stock levels as soon as possible, since sourcing the exact same model later may not be possible. ### What warranty comes with the VDS-S144/M6H panels? VDS Renewable backs this series with a 12-year product warranty and a 25-year linear power output warranty. This covers material and workmanship defects for 12 years and guarantees a minimum power output level over a quarter century of operation, which is standard for commercial installations and utility-scale PV farms. ### How do the half-cut cells in the VDS-S144/M6H differ from standard full-size cells? Half-Cut Cell technology splits each cell in half and wires both halves into independent circuits within the panel. This reduces resistive losses, improves tolerance to partial shading, and slows the performance drop typically seen in full-cell modules during hot weather. The result is higher real-world energy yield under demanding operating conditions. ### Are the VDS-S144/M6H panels suitable for large commercial installations and solar farms? Yes, this series was primarily designed for large-scale commercial installations and solar farms. A maximum power of 460 Wp combined with M6 cells delivers strong power density per mounting area, while the reinforced mechanical structure and multi-busbar technology reduce the risk of microcracks at scale over long-term operation. ### What is the power rating of the VDS-S144/M6H panels, and how many are needed for a 10 kWp system? Panels in this series reach a maximum power of 460 Wp. Building a 10 kWp system therefore requires roughly 22 modules (10,000 W / 460 W ≈ 21.7, rounded up). The exact count depends on available mounting space and inverter selection, including its input voltage range. ### Are the VDS-S144/M6H panels bifacial, generating power from both sides? No, the VDS-S144/M6H series is monofacial, generating energy only from the front, light-facing surface. If you need extra yield from reflected light, such as on light-colored surfaces or ground-mounted systems, consider a bifacial model from another series by this manufacturer. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/435-460W-166-144cells-3c466a9496a9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, cooler, +4.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +4.0 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | Cooler, +4.0 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | Cooler, +3.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | Cooler, +3.8 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +3.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | Cooler, +3.8 pp, +5 yr warranty | | [VDS Renewable VDS-S144/M6H-BG-430W](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-430w) | 430 W | -15 W, heavier, -0.8 pp | | [VDS Renewable VDS-S144/M6H-BG-435W](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-435w) | 435 W | -10 W, heavier, -0.5 pp | | [VDS Renewable VDS-S144/M6H-BG-440W](https://comparepv.com/panel/vds-renewable-vds-s144-m6h-bg-440w) | 440 W | Heavier, -0.3 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +145 W, +3.3 pp, +5 yr warranty | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +140 W, +3.1 pp, +5 yr warranty | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +135 W, cooler, +3.0 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +135 W, +2.9 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/vds-renewable-vds-s144-m6h-445 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
