The use of **monocrystalline PERC cells** and a **half-cut** architecture allows for reduced internal losses and better performance under partial shading - when shadows from chimneys, eaves, or trees can reduce output in standard modules. The **M10 technology** also plays a significant role in this series, supporting high power density while maintaining good performance on warmer days - which is important in Polish rooftop installations where modules heat up in the summer. The manufacturer emphasizes **enhanced resistance to demanding environments** thanks to high-quality lamination materials and a well-designed module structure, which reduces the risk of micro-cracks and performance degradation over time. Yingli LFxxxM10-72H is a good choice for installers and investors looking for modules for larger commercial installations, solar farms, and extensive prosumer systems, where repeatability of parameters and predictable yields are key. ## Notable figures - Module efficiency of 21.5% is 0.9pp below average for \*\*N-type 550-600W\*\* panels (median: 22.4%) - 214.8 W/m² power density is 9.8 W/m² below \*\*N-type 550-600W\*\* median (224.5 W/m²) - requires larger installation area - Temperature coefficient of -0.35%/°C is 0.06pp worse than \*\*N-type 550-600W\*\* median (-0.29%/°C) - higher losses in summer heat - Weight of 28.5 kg (1.8 kg below \*\*N-type 550-600W\*\* median of 30.3 kg) allows easier transport and roof mounting - In the top 57% for efficiency among all N-type panels ## Questions ### What is the maximum power output of the Yingli LFxxxM10-72H panel? Panels from the LFxxxM10-72H series reach a maximum power output of up to 555 Wp. This high output results from M10 cell technology with larger cells and half-cut architecture, allowing more energy to be generated per unit of roof or ground area compared to smaller, older modules of similar dimensions. ### What warranty comes with the Yingli LFxxxM10-72H series? The manufacturer provides a 12-year product warranty and a 25-year linear power output warranty. This means Yingli guarantees a defined minimum power production level for a quarter of a century, giving investors confidence in the long-term profitability of commercial installations and solar farms. ### How do N-type cells in the LFxxxM10-72H differ from standard PERC panels? N-type cells have a lower degradation rate over time and reduced susceptibility to light-induced degradation (LID) compared to standard P-type cells. This translates into more stable energy yields throughout the system's lifetime, particularly noticeable after a decade or more of operation. ### Are the Yingli LFxxxM10-72H panels bifacial? No, this series uses monofacial modules rather than bifacial ones. Energy is generated only from the front side of the panel, which is a standard, proven solution for typical rooftop and ground-mounted installations without requiring specially reflective ground surfaces. ### What types of installations are the Yingli LFxxxM10-72H panels suited for? The LFxxxM10-72H series is designed for larger commercial installations, solar farms, and extensive prosumer systems. The high power rating per module and consistent parameters make it easier to design large-scale installations where predictable yields and optimized string sizing are critical. ### Is Yingli a Tier 1 manufacturer, and is it a safe choice for a large investment? Yes, Yingli holds Tier 1 manufacturer status, reflecting strong financial stability and decades of experience in global photovoltaic module production. For installers and investors, this is a key indicator that manufacturer warranties will be honored and that material quality and production processes undergo rigorous control. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/LF535-555M10-72H-EN-53b25d4c6482.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.5 pp | | [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 | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 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 | | [Yingli YL530DF72 e/2](https://comparepv.com/panel/yingli-yl530df72-e-2) | 530 W | Heavier, -1.0 pp, +5 yr warranty | | [Yingli YL535DF72 e/2](https://comparepv.com/panel/yingli-yl535df72-e-2) | 535 W | Heavier, -0.8 pp, +5 yr warranty | | [Yingli LF535M10-72H](https://comparepv.com/panel/yingli-lf535m10-72h) | 535 W | -20 W, -0.8 pp | | [Yingli YL540DF72 e/2](https://comparepv.com/panel/yingli-yl540df72-e-2) | 540 W | Heavier, -0.6 pp, +5 yr warranty | | [Yingli LF540M10-72H](https://comparepv.com/panel/yingli-lf540m10-72h) | 540 W | -15 W, -0.6 pp | | [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 | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +75 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/yingli-lf555m10-72h Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
