The use of **M10 silicon cells in a half-cut architecture** allows for the effective reduction of internal energy losses, which translates into higher module efficiency even under partial shading or in diffused light conditions. This series solves a key problem for investors - the need to optimize structural costs - by offering **exceptionally high power density** while maintaining standard mounting dimensions. The robust frame design and the use of high-transmittance tempered glass ensure **above-average resistance to LID and LeTID degradation**, guaranteeing the stability of electrical parameters throughout the entire life cycle of the installation. The product is dedicated to demanding commercial projects where a fast return on investment and failure-free operation in harsh weather conditions are paramount. It stands out from the competition due to its **precise compatibility with modern high-current inverters**, which simplifies system design and minimizes the risk of losses during the energy transmission stage. Thanks to an **optimized temperature coefficient**, these panels maintain high efficiency even on hot days, delivering significantly more kilowatt-hours than standard modules with similar nominal power. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - At 212.8 W/m² power density, roof space requirements are typical for \*\*PERC 550-600W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - 28.5 kg weight - 2.3 kg lighter than \*\*PERC 550-600W\*\* median (30.8 kg), reducing installation effort - #8585 for efficiency, #12365 for temperature performance out of 14129 panels ## Questions ### What warranty covers the Yingli LF 555M10-72H panels and what exactly does it include? The manufacturer provides a 12-year product warranty against material and workmanship defects, plus a 25-year linear power output warranty. This means that after 25 years of operation the module should retain a significant share of its rated performance, giving investors confidence in stable energy yield throughout the lifetime of a commercial or ground-mount installation. ### How does the half-cut M10 cell technology in the LF 555M10-72H differ from standard full-size cells? Half-cut cells are cut in half, reducing resistive losses and the current flowing through the module. This allows the LF 555M10-72H to achieve higher efficiency, lower power loss under partial shading, and better resistance to microcracks. In practice, this translates into higher energy yield from the same roof or ground area. ### Are Yingli LF 555M10-72H panels suitable for large ground-mount solar farms? Yes, the LF 555M10-72H series is designed for commercial and utility-scale projects. The high 555 Wp power output in standard mounting dimensions reduces the number of modules, mounting structures, and cabling needed, lowering BoS costs and shortening the payback period on large ground-mounted installations. ### How do LF 555M10-72H panels perform in high summer temperatures? The module has an optimized power temperature coefficient, so it loses less efficiency as cell temperature rises compared to standard PERC panels. In practice, this means higher energy yield on hot days and in high-irradiance regions, where module surface temperature can exceed 60°C. ### Is the Yingli LF 555M10-72H compatible with modern high-current inverters? Yes, the panel's electrical parameters are matched to current generations of string and central inverters handling high input currents. This simplifies string design with fewer modules in series, reduces transmission losses, and streamlines component selection, especially for commercial and industrial projects. ### Is Yingli a Tier 1 manufacturer, and is the LF 555M10-72H a reliable choice for a large investment? Yingli is recognized as a Tier 1 manufacturer, meaning financial stability, in-house production lines, and inclusion in solar panel bankability rankings. Tier 1 status makes it easier to secure bank financing for commercial projects, as financial institutions are more willing to accept modules from manufacturers with a proven track record and production scale. ## 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, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +3.2 pp | | [Yingli YL530DF72 e/2](https://comparepv.com/panel/yingli-yl530df72-e-2) | 530 W | Heavier, -0.8 pp, +5 yr warranty | | [Yingli YL535DF72 e/2](https://comparepv.com/panel/yingli-yl535df72-e-2) | 535 W | Heavier, -0.6 pp, +5 yr warranty | | [Yingli LF535M10-72H](https://comparepv.com/panel/yingli-lf535m10-72h) | 535 W | -15 W, -0.6 pp | | [Yingli YL540DF72 e/2](https://comparepv.com/panel/yingli-yl540df72-e-2) | 540 W | Heavier, -0.4 pp, +5 yr warranty | | [Yingli LF540M10-72H](https://comparepv.com/panel/yingli-lf540m10-72h) | 540 W | -10 W, -0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/yingli-lf-550m10-72h Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
