They are distinguished by **N-type monocrystalline cell technology**, which helps to minimize typical power losses associated with degradation and maintain performance better in hot weather. The use of **bifacial construction with double glass** allows for the recovery of additional energy from reflected light, which is important on bright roofs, gravel, and ground-mounted installations with appropriate backsheets. In practice, these panels facilitate the design of high-density power installations while also increasing predictability of energy yields during transitional seasons due to their good performance under less intense sunlight. Another advantage is **the half-cut design**, which improves module performance under partial shading and reduces internal losses. This series is suitable for demanding investors, from single-family homes to **commercial roofs and PV farms**, wherever durability and resistance to environmental conditions are important. ## Notable figures - At 22.8% efficiency, this panel is on par with typical \*\*N-type 450-500W\*\* modules - At 227.7 W/m² power density, roof space requirements are typical for \*\*N-type 450-500W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - Weight of 21.5 kg (2.2 kg below \*\*N-type 450-500W\*\* median of 23.7 kg) allows easier transport and roof mounting - Ranked #3073 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Sunlike Solar SKT450~470M12-96D4 series come with? The SKT450~470M12-96D4 series comes with a 15-year product warranty covering defects in materials and workmanship, plus a 30-year linear power output warranty. Over three decades, the manufacturer guarantees a minimum power retention level. N-type cell technology delivers lower annual degradation than conventional P-type cells, making this extended power warranty a meaningful safeguard for long-term return on investment. ### Do Sunlike Solar SKT470 N-type panels really perform better in high heat compared to standard panels? Yes. N-type cells have a lower temperature coefficient than PERC (P-type) cells, meaning less power loss when modules heat up — critical during summer when panels can reach 60–80°C. The SKT450~470M12-96D4 series is specifically engineered for stable year-round production, including during heat waves, giving it a measurable advantage over older PERC technology in warm climates. ### Will the bifacial SKT470 generate extra energy on a typical pitched roof with standard tiles? The bifacial gain depends on the albedo (reflectivity) of the surface below the module. On dark roofing tiles or bitumen, the rear side receives too little reflected light for a meaningful yield boost. The bifacial advantage of the SKT450~470M12-96D4 series is most significant in ground-mount systems with light gravel, white roofing membranes, or facade installations. On a standard pitched roof, the primary value drivers remain the N-type cells and the half-cut cell layout. ### How do the SKT450~470M12-96D4 panels differ from cheaper PERC modules at the same wattage? The key difference is cell technology: the SKT450~470M12-96D4 uses N-type cells with lower annual degradation (typically below 0.4% vs. around 0.55% for PERC), better low-light performance, and higher temperature tolerance. The bifacial dual-glass construction also extends module lifespan and improves resistance to moisture and mechanical stress compared to the standard backsheet used in most PERC modules. ### Is the SKT450~470M12-96D4 series suitable for a commercial solar farm? Yes, this series is designed with demanding applications in mind — from commercial rooftops to utility-scale ground-mount systems. With up to 470 Wp peak power, a 96-cell half-cut layout, and a bifacial dual-glass construction, it delivers high power density per square meter and predictable long-term yield. The 30-year power warranty is a significant factor when modeling LCOE for commercial PV investments. ### Does the half-cut cell design in Sunlike SKT470 panels actually reduce shading losses? Half-cut cells split each cell in two, forming two independent electrical circuits within the module. When one section of the panel is shaded — by a chimney, antenna, or adjacent row — the other half continues producing at full capacity. In practice, the SKT450~470M12-96D4 series loses significantly less power under partial shading than conventional full-cell modules, which has a real impact on annual yield in installations with non-ideal exposure conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1-4-skt450-470m12-96d4-fb-tg-1-6mm-7bded6f0efb8.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, cooler, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Sunlike Solar SKT420M10-108D6](https://comparepv.com/panel/sunlike-solar-skt420m10-108d6) | 420 W | -35 W, -1.8 pp | | [Sunlike Solar SKT425M10-108D6](https://comparepv.com/panel/sunlike-solar-skt425m10-108d6) | 425 W | -30 W, -1.5 pp | | [Sunlike Solar SKT440M12-96D4](https://comparepv.com/panel/sunlike-solar-skt440m12-96d4) | 440 W | -15 W, cooler, -0.8 pp | | [Sunlike Solar SKT445M10-108D6](https://comparepv.com/panel/sunlike-solar-skt445m10-108d6) | 445 W | -10 W, -0.5 pp | | [Sunlike Solar SKT450M10-108D6](https://comparepv.com/panel/sunlike-solar-skt450m10-108d6) | 450 W | -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/sunlike-solar-skt455m12-96d4 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.
