**Half-cut technology reducing hotspots** - 72 half-cut monocrystalline cells lower current losses and reduce hotspot risk, delivering higher energy yield under partial shading compared to conventional full-cell modules. - **Positive power tolerance** - Modules guarantee real-world output never below rated nameplate parameters, eliminating the risk of underestimated energy production when designing commercial and industrial installations. - **High mechanical load rating of 5400 Pa** - Certified resistance to loads up to 5400 Pa makes the series suitable for both high-wind roof zones and heavy-snow-load regions, exceeding the standard 2400/5400 Pa threshold common in this segment. - **PID resistance** - Passing rigorous PID testing minimizes power loss risk from potential-induced degradation, an important factor for large installations with long, high-voltage strings. - **Long-established manufacturer** - Motech, a Taiwan-based manufacturer operating since 1981, has built decades of expertise in crystalline cell and module production, reflecting mature process quality control for the XS72+ series. ## Cons - **Series discontinued** - The XS72+ series (launched in 2012) is no longer in production, meaning limited availability of identical replacement modules and potential difficulties with future warranty servicing. - **Efficiency below segment leaders** - Maximum efficiency of 21.29% is comparable to Jetion JT SGh (21.3%) and IBC Solar 182M (21.28%) but clearly trails Gamko GKA182N132 (23.16%) - a gap of roughly 1.9 pp that translates to lower energy yield per roof area. - **No bifacial variant** - Unlike some newer designs in the 530-550 Wp segment, the XS72+ series offers no bifacial option, ruling out additional albedo-driven yield in ground-mount installations and light-colored roof surfaces. - **Shorter product warranty** - The 12-year product warranty is shorter than the 15-25 year standard now offered by many tier-1 manufacturers, which can affect perceived bankability for long-term project financing. ## About this series The XS72+ series is a line of photovoltaic modules built around **half-cut cell technology**, where 72 monocrystalline cells are cut in half and wired to reduce resistive losses and lower the risk of hotspot formation. This design translates into higher energy yield across the array, particularly under partial shading conditions where conventional panels lose significantly more output. The series stands out for its **positive power tolerance**, ensuring actual energy output never falls short of the rated parameters, which simplifies precise system design and reduces the risk of underestimating production. The modules have undergone rigorous **PID resistance** testing and have been verified for **mechanical load resistance up to 5400 Pa**, making them a solid choice for both wind-exposed roofs and regions with heavy snow loads. The manufacturer backs the series with a **25-year progressive power warranty**, guaranteeing sustained high performance throughout the system's operational life. The XS72+ is well suited to commercial and industrial projects where predictable return on investment, long-term reliability, and resilience to harsh weather conditions matter most. ## Notable figures - Efficiency of 21.1% is 0.7pp below the \*\*database\*\* median (21.8%) - 211.0 W/m² power density is 7.1 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - -0.35%/°C temperature coefficient - 0.05pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - Weight of 28.1 kg is 1.6 kg above \*\*database\*\* median (26.5 kg) - verify structural support - Ranked #9297 out of 14005 panels for efficiency in the database ## Questions ### Is the Motech XS72+ series still available for purchase? The XS72+ series has been discontinued by Motech and is no longer offered as a new product. Panels may still be found in distributor stock or as clearance offers, but availability should be confirmed with a local supplier before planning a larger installation, since restocking additional modules in the future may be difficult. ### What is the maximum power output of an XS72+ series panel? XS72+ series modules reach a maximum power output of up to 550 Wp. This is achieved through half-cut technology applied to 72 monocrystalline cells, which increases the panel's power density within standard dimensions, meaning fewer modules are needed to reach a targeted installation capacity. ### What is half-cut technology in the XS72+ panels and is it worth choosing? Half-cut technology involves splitting 72 monocrystalline cells in half and connecting them in a configuration that reduces current losses. This means the panel loses less power under partial shading, such as from a chimney or antenna, and the risk of hotspots is lower. It's a good choice especially where the roof isn't fully exposed to sunlight throughout the day. ### What warranty comes with Motech XS72+ panels? The manufacturer provides a 12-year product warranty and a 25-year linear power warranty. This means the module maintains a guaranteed efficiency level for a quarter century, and thanks to positive power tolerance, actual energy yield never falls below the rated nameplate parameters from day one of operation. ### Can XS72+ panels withstand heavy snow loads and strong wind? Yes, XS72+ modules have been tested for mechanical load resistance up to 5400 Pa, a higher value than standard requirements for most rooftops. They are suitable for regions with heavy snowfall as well as buildings exposed to strong wind gusts, such as tall commercial structures. ### Are XS72+ panels bifacial, and are they suitable for industrial installations? No, the XS72+ series uses standard monofacial monocrystalline cells rather than bifacial technology. Nevertheless, thanks to PID resistance, high mechanical durability, and a long power warranty, these panels perform well in commercial and industrial projects where predictable ROI and reliability under harsh conditions matter most. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/XS72CF_series_datasheetFor_Oversea-85abb6d58df2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.9 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.6 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.4 pp, +5 yr warranty | | [Motech XS72CF-540](https://comparepv.com/panel/motech-xs72cf-540) | 540 W | -0.2 pp | | [Motech XS72CF-550](https://comparepv.com/panel/motech-xs72cf-550) | 550 W | Very close match | | [Motech XN72KF-580](https://comparepv.com/panel/motech-xn72kf-580) | 580 W | +35 W, cooler, +1.3 pp | | [Motech XN72KF-585](https://comparepv.com/panel/motech-xn72kf-585) | 585 W | +40 W, cooler, +1.5 pp | | [Motech XN72KF-590](https://comparepv.com/panel/motech-xn72kf-590) | 590 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/motech-xs72cf-545 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
