The use of **N-type cells** in combination with modern **half-cut** architecture results in more stable performance in real-world conditions and better resistance to typical operating factors that can reduce panel performance over time. A key advantage of this series is the **bifacial design**, which can "collect" additional light reflected from the ground, allowing the installation to produce more energy without increasing the number of modules. The SL5N144D also features **double-glazed** glass and encapsulation materials selected for long life and high reliability in varying weather conditions. This is a good choice for PV farms, commercial installations, and modern flat roofs, where high power density and long-term profitability are important. ## Notable figures - At 22.4% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - Power density of 224.0 W/m² is 3.7 W/m² below \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - needs more roof space - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - Ranked #4774 out of 14005 panels for efficiency in the database ## Questions ### What is the maximum power output of SunLink SL5N144D panels and what does it mean in practice? The SunLink SL5N144D series reaches a peak output of up to 610 Wp under Standard Test Conditions (STC). This is significantly higher than typical premium modules available just a few years ago. In practice, it means you can generate more energy from the same roof or ground area without adding extra panels, which lowers the overall system cost per kilowatt of installed capacity. ### What warranty does SunLink offer on the SL5N144D series? SunLink provides a 15-year product warranty on the SL5N144D modules, covering material and manufacturing defects. A separate 30-year linear power output warranty guarantees that the modules maintain a specified performance level throughout their service life. Before purchasing, confirm that your local distributor or installer has an established warranty claims process directly with SunLink. ### What is TOPCon technology in the SL5N144D panels and why does it matter? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that adds a thin tunnel oxide layer to reduce carrier recombination at the contact interface. Compared to standard PERC modules, this results in higher cell efficiency and a lower temperature coefficient, meaning SL5N144D panels lose less power on hot days and degrade more slowly over their operational lifetime. ### Are the bifacial SunLink SL5N144D modules a good fit for flat-roof installations? Yes, flat roofs are one of the ideal use cases for the SL5N144D series. The bifacial design captures albedo light reflected from a bright membrane or gravel surface beneath the modules, potentially boosting yield by several percentage points. The dual-glass construction also protects the rear surface from moisture, which is particularly important where airflow under the modules may be limited. ### Are SunLink SL5N144D panels compatible with popular inverters available in Europe? The SL5N144D modules produce open-circuit voltage and short-circuit current values typical of 600+ Wp panels, so compatibility depends on your inverter's maximum DC input voltage and MPPT voltage range. Most string inverters from established brands such as SMA, Fronius, Huawei, and SolarEdge can handle these parameters, but always ask your installer to verify compatibility against the module datasheet before purchase. ### Is SunLink a Tier 1 manufacturer and does it matter when buying SL5N144D panels? SunLink does not currently appear on Tier 1 lists published by analytical agencies such as BloombergNEF. This does not automatically indicate lower product quality, but it is worth considering the availability of warranty service and the financial stability of the distributor in your region. For commercial installations and utility-scale PV farms in particular, we recommend verifying the importer's track record and the specific terms of the warranty claims procedure before committing to a purchase. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/sl5n144d-605-610-watt-edf048590f02.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +45 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +40 W, lighter, +2.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -45 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | Cooler, lighter, +2.2 pp | | [SunLink SL5N144D-610W](https://comparepv.com/panel/sunlink-sl5n144d-610w) | 610 W | +0.2 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +95 W, cooler, +2.6 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +90 W, cooler, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +65 W, lighter, +2.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +65 W, lighter, +2.4 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +65 W, cooler, +2.4 pp | --- Source: https://comparepv.com/panel/sunlink-sl5n144d-605w Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
