**High-efficiency N-type half-cut technology** - 144 N-type half-cut cells with double-glass construction deliver 22.45-22.84% efficiency, in line with comparable flagship peer series (Talesun TM7G72M 22.8%, Horay HS Ocean 22.8%, AE Solar HORIZON CMD-144BDS 22.86%), with lower LID/PID degradation than older PERC cells. - **Double-glass build with 5400 Pa load rating** - The dual-glass layer limits module degradation and improves mechanical durability, with verified mechanical load testing up to 5400 Pa making the series suitable for sites exposed to strong wind and heavy snow loads. - **Positive power tolerance of 0~+3%** - The module never falls below its rated power, eliminating underperformance risk for investors and simplifying accurate financial modeling of the installation. - **Progressive power warranty: 89.4% at year 25** - The 25-year progressive power warranty guarantees 89.4% of rated power after a quarter-century - above the typical segment range of 84.8-87.4% - complemented by a 12-year product/workmanship warranty, in line with the 2026 market standard for N-type modules. - **1500V max system voltage and manufacturing pedigree** - A 1500V maximum system voltage enables longer strings and lower BoS costs, while Motech - active in solar since 1997 and Taiwan's largest solar cell manufacturer - brings a mature manufacturing base. ## Cons - **Smaller production scale than industry giants** - Motech's cell production capacity (~3.2 GW) is far smaller than top-tier Chinese manufacturers like Jinko, LONGi, or Trina (>80 GW annually), which may translate into weaker pricing leverage and a shorter bankability track record on global Tier 1 lists compared to market leaders. - **25-year power warranty horizon shorter than segment leaders** - While the XN72KF guarantees 89.4% power at year 25, flagship N-type series from market leaders (e.g., JinkoSolar Tiger Neo 3.0) already offer 30-year linear warranties guaranteeing 87.4% power - investors seeking the longest possible coverage period will find more favorable alternatives on this metric. ## About this series The XN72KF series by Motech is built around 144 **N-type half-cut cells** encased in a double-glass structure, delivering exceptional durability and stable energy output throughout the module's service life. The **double glass design** effectively curbs degradation and boosts mechanical resistance, making the panels well suited for both rooftop installations and large-scale solar farms exposed to demanding weather conditions. The series stands out with a **positive power tolerance of 0~+3%**, meaning actual module output never falls below the rated value - giving investors confidence in the real-world performance of their installation. Verified **PID resistance** combined with load testing up to 5400 Pa make the XN72KF a solid choice for regions exposed to strong wind and heavy snow loads. Motech backs the series with a **25-year progressive power warranty** guaranteeing 89.4% of rated power after a quarter century, plus a 12-year warranty on materials and workmanship. With a maximum system voltage of 1500V, the modules integrate easily with modern inverters and allow for longer strings, reducing BoS costs. This makes the XN72KF a compelling option for investors seeking high reliability and predictable ROI. ## Notable figures - Efficiency of 22.4% matches the \*\*N-type 550-600W\*\* median - Power density of 224.5 W/m² matches the \*\*N-type 550-600W\*\* median - At -0.29%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - At 31.6 kg, this panel is 2.1 kg heavier than the \*\*N-type 550-600W\*\* median (29.5 kg) - more demanding for installation crews - #4620 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### Are Motech XN72KF panels bifacial, and how much extra energy can they generate? Yes, the XN72KF series uses N-type cells in a bifacial design, so the rear side also generates energy from reflected light. Depending on the ground albedo (light gravel, white roofing membrane), the additional energy yield can range from a few percent up to more than ten percent compared to a monofacial module of the same front-side power. ### What warranty does Motech offer on the XN72KF series, and how much power remains after 25 years? Motech provides a 12-year product warranty covering materials and workmanship, along with a 25-year linear power warranty. The manufacturer guarantees at least 89.4% of rated power after a quarter century of operation, resulting in low annual degradation and predictable energy yield throughout the system's lifetime. ### How does N-type half-cut technology in the XN72KF differ from conventional P-type panels? N-type cells use higher-purity silicon and are not susceptible to light-induced degradation (LID), resulting in higher efficiency and less power loss over time compared to traditional P-type panels. Additionally, half-cut technology, splitting 144 cells in half, reduces resistive losses and improves partial shading tolerance. ### Are XN72KF panels suitable for large utility-scale solar farms exposed to heavy wind and snow loads? Yes, the XN72KF series has passed mechanical load testing up to 5400 Pa, corresponding to very heavy snow and wind loads. The double-glass construction further increases the module's mechanical rigidity, making these panels a popular choice for utility-scale PV farms in harsh climates, not just rooftop installations. ### What does the 0~+3% positive power tolerance mean for Motech XN72KF panels? A positive power tolerance means the actual delivered power of the module is never lower than the rated nameplate value and can be up to 3% higher. This gives investors confidence that the real system output will match the design assumptions, without risk of underestimating energy production. ### Are 590 Wp XN72KF panels compatible with low-voltage inverters? XN72KF panels have a maximum system voltage of 1500V, which is the standard for most modern string and central inverters. This allows for longer module strings to be designed, reducing the amount of cabling and BoS components needed and lowering the overall cost of the installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/XN72KF_series_datasheetFor_Oversea-6583a9fffd57.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Lighter, +2.4 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Lighter, +2.2 pp, +5 yr warranty | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +50 W, +1.9 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | 15 kg lighter, +1.9 pp, +5 yr warranty | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Lighter, +1.9 pp, +5 yr warranty | | [Motech XS72CF-540](https://comparepv.com/panel/motech-xs72cf-540) | 540 W | -40 W, hotter, -1.6 pp | | [Motech XS72CF-545](https://comparepv.com/panel/motech-xs72cf-545) | 545 W | -35 W, hotter, -1.3 pp | | [Motech XS72CF-550](https://comparepv.com/panel/motech-xs72cf-550) | 550 W | Hotter, lighter, -1.2 pp | | [Motech XN72KF-585](https://comparepv.com/panel/motech-xn72kf-585) | 585 W | Very close match | | [Motech XN72KF-590](https://comparepv.com/panel/motech-xn72kf-590) | 590 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +70 W, +2.8 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +65 W, +2.6 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +60 W, +2.4 pp, +5 yr warranty | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +55 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/motech-xn72kf-580 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.
