**Half-cut + Multi Bus Bar design** - The half-cut cell architecture combined with Multi Bus Bar technology reduces partial-shading losses and improves resistance to microcracks, supporting more stable output in daily operation, especially on roofs with complex geometry. - **Efficiency on par with segment leaders** - Efficiency up to 21.68% and power up to 560 Wp put the series on par with comparable models from Exiom (21.7%), Fellow Energy (21.7%) and Premier Energies (21.67%) - a competitive result for 144-cell PERC modules. - **Stäubli MC4 EVO 2 connectors** - Using proven Stäubli MC4 EVO 2 connectors instead of cheaper alternatives reduces the risk of installation failures and power losses from leaks or contact corrosion over long-term operation. - **PID control and 25-year power warranty** - Enhanced quality control limiting PID risk, combined with a 25-year power warranty (84.8% of nominal power guaranteed at year 25), gives investors a predictable yield profile in line with market standards for this module class. ## Cons - **No Tier-1 manufacturer status** - LEDVANCE as a renewables brand does not appear on the BNEF Tier-1 manufacturer list - in practice this can complicate bank financing or insurance for larger commercial projects, where lenders and insurers favor suppliers with an established bankability track record. - **Monofacial only** - Unlike some comparable offerings in the segment (e.g., bifacial dual-glass modules up to 560 Wp from Premier Energies), the M540~560P72LM-SF-F7 series is monofacial, ruling out the additional rear-side yield gain available from ground-mounted or high-albedo installations. ## About this series The LEDVANCE M540~560P72LM-SF-F7 series are modules engineered for installations where stable energy production and predictable performance over years are crucial. The use of monocrystalline cells in a **half-cut** architecture helps reduce losses during partial shading, effectively supporting energy yield on complex roof geometries and in urban developments. The **bifacial** construction allows additional use of reflected light from the ground - a significant advantage especially in ground-mounted systems, on light-colored roofs, or where controlled reflection conditions can be ensured. Another key feature is the **Multi Bus Bar technology**, which improves power harvesting and enhances resistance to micro-cracking during daily operation. These modules are further equipped with **Stäubli MC4 EVO 2 connectors** and refined quality control, minimizing the risk of PID, making them highly valued by installers and investors seeking reliable series for homes, businesses, and industrial projects. ## Notable figures - Efficiency of 21.5% matches the \*\*PERC 550-600W\*\* median - Power density of 214.8 W/m² matches the \*\*PERC 550-600W\*\* median - Temperature coefficient of -0.34%/°C matches the \*\*PERC 550-600W\*\* median - 27.5 kg weight - 3.3 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg), reducing installation effort - #7958 for efficiency, #8753 for temperature performance out of 14005 panels ## Questions ### What is the peak power output and efficiency of the LEDVANCE M540~560P72LM-SF-F7? The M540~560P72LM-SF-F7 series reaches up to 560 Wp under STC conditions, with module efficiency up to 21.68%. The 144-cell mono PERC half-cut configuration delivers high power density in a compact footprint, making it a competitive upgrade over older 72-cell full-cell modules for both rooftop and ground-mount installations. ### What warranty does the LEDVANCE M540~560P72LM-SF-F7 come with? LEDVANCE provides a 12-year product warranty covering manufacturing defects and a 25-year linear power output warranty. At year 25, the module is guaranteed to retain at least 84.8% of its rated output. These terms are consistent with industry standards and provide a reliable basis for calculating long-term energy yield and return on investment. ### What are the benefits of half-cut cells and Multi Bus Bar technology in the LEDVANCE M540~560P72LM-SF-F7? Half-cut PERC cells reduce internal resistance and limit power losses under partial shading — for example from chimneys or dormers on complex rooftops. Multi Bus Bar technology improves current collection per cell and reduces mechanical stress, lowering the risk of microcracks during daily thermal cycling. Together, these features deliver higher real-world energy yield and a longer module service life. ### What are the dimensions and weight of the LEDVANCE M540~560P72LM-SF-F7, and can it be installed on a typical sloped roof? The panel measures 2278 × 1134 × 35 mm and weighs approximately 27.5 kg. The silver anodized frame is compatible with standard rail-based racking systems used on pitched roofs. At around 27.5 kg, no special lifting equipment is required, though two-person installation is recommended for safe handling and placement on sloped surfaces. ### How does the LEDVANCE M540~560P72LM-SF-F7 protect against PID, and why does it matter? PID (Potential Induced Degradation) is a gradual power loss caused by leakage currents triggered by high system voltages and moisture ingress through the laminate. The M540~560P72LM-SF-F7 series undergoes rigorous quality control to minimize PID risk and is fitted with Stäubli MC4 EVO 2 connectors, which maintain a weatherproof seal and reliable electrical contact throughout the system's lifetime. This matters most in commercial and industrial string inverter setups operating at higher DC voltages. ### Is LEDVANCE a reliable solar panel manufacturer, and is the M540~560P72LM-SF-F7 available outside Germany? LEDVANCE is a German company best known for LED lighting that has expanded into photovoltaics. The M540~560P72LM-SF-F7 series is available through authorized distributors across Europe. Note that LEDVANCE does not currently appear on Bloomberg NEF's Tier 1 solar module manufacturer list, which may be a consideration for projects that require bankable Tier 1 certification as a condition of project financing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/asset-13237348-m540-560p72lm-sf-f7-45a1921428c2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -50 W, cooler, +3.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.1 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.9 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, +2.9 pp, +5 yr warranty | | [LEDVANCE M540P72LM-SF](https://comparepv.com/panel/ledvance-m540p72lm-sf) | 540 W | -15 W, -0.6 pp | | [LEDVANCE M545P72LM-SF](https://comparepv.com/panel/ledvance-m545p72lm-sf) | 545 W | -10 W, -0.4 pp | | [LEDVANCE M550P72LM-SF](https://comparepv.com/panel/ledvance-m550p72lm-sf) | 550 W | Very close match | | [LEDVANCE M560P72LM-SF](https://comparepv.com/panel/ledvance-m560p72lm-sf) | 560 W | Very close match | | [LEDVANCE M565N72LB-SF-F3](https://comparepv.com/panel/ledvance-m565n72lb-sf-f3) | 565 W | Cooler, heavier, +5 yr warranty | | [LEDVANCE M570N72LB-SF-F3](https://comparepv.com/panel/ledvance-m570n72lb-sf-f3) | 570 W | Cooler, heavier, +5 yr warranty | | [LEDVANCE M575N72LB-SF-F3](https://comparepv.com/panel/ledvance-m575n72lb-sf-f3) | 575 W | Heavier, +0.8 pp, +5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/ledvance-m555p72lm-sf Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
