The use of **mono half-cell** construction helps to minimize losses caused by microcracks and partial shading - which, in practice, means more stable operation of rooftop installations with chimneys, skylights, or trees nearby. The **multi-busbar design** also deserves attention, as it improves the collection of current from the cells and enhances the module's resistance to degradation over time. Furthermore, the **anti-reflective glass** supports energy generation in less sunny conditions by reducing light reflection. This is a good choice for residential and commercial installations where high power density on a limited area and predictable annual yields are important. The series features a more modern cell technology and a practical approach to real-world operational challenges. ## Notable figures - Module efficiency of 21.8% is 0.7pp below average for \*\*TOPCon 450-500W\*\* panels (median: 22.5%) - Power density of 217.1 W/m² is 8.1 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - needs more roof space - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 450-500W\*\* panels - #7206 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### Is the SunKean SKT460~480M10-120D3 series still available for purchase? The SKT460~480M10-120D3 series has been discontinued and is no longer actively manufactured by SunKean. Limited stock may still be available through distributors, but for new installations it is advisable to consider currently active TOPCon module lines from SunKean or other manufacturers. Always verify stock availability and warranty terms with your supplier before ordering. ### What warranty does SunKean provide for the SKT460~480M10-120D3 modules? SunKean backs the SKT460~480M10-120D3 series with a 15-year product warranty covering manufacturing defects, plus a 30-year linear power output warranty guaranteeing minimum performance thresholds over three decades. The 30-year power warranty is one of the more competitive commitments in the industry and is a key factor when calculating the long-term LCOE of a solar installation. ### What is TOPCon technology and why does it matter for the SKT460~480M10-120D3 series? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation monocrystalline cell architecture that outperforms PERC in both efficiency and temperature coefficient. A thin tunnel oxide layer minimizes carrier recombination, enabling better energy harvest in diffuse light and high-heat conditions. In the SKT460~480M10-120D3 series, this translates to higher annual yield compared to PERC modules of similar dimensions. ### Are the SKT460~480M10-120D3 panels bifacial, and what does that mean for real-world output? Yes, the SKT460~480M10-120D3 is a bifacial module, meaning it generates power from both the front and rear surfaces. The rear side captures albedo-reflected light from surfaces such as light-colored roofing membranes, gravel, or snow. Actual bifacial gain depends on installation angle and ground reflectance, but typically ranges from 3% to 8% additional annual energy production. ### What is the peak power output of the SunKean SKT460~480M10-120D3, and how does it compare to older panels? The top-tier module in the SKT460~480M10-120D3 series reaches 480 Wp, positioning it in the high power-density segment suitable for both residential and commercial systems. The 120 half-cut cells in the M10 (182 mm) format deliver this output in a compact footprint. By comparison, similarly sized PERC modules from a few years ago typically topped out at 400–430 Wp. ### Will the SKT460~480M10-120D3 panels perform well on a roof with partial shading from a chimney or trees? The half-cut cell design splits each cell in two, limiting power loss when shade falls on part of the module — shadow on one half does not fully suppress the other. The multi-busbar layout further distributes current flow and reduces hotspot risk. The SKT460~480M10-120D3 series is therefore a solid choice for roofs with chimneys, dormers, or nearby vegetation, though heavy shading scenarios may still benefit from per-module MPPT power optimizers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/3-3-182mm-16BB-120Cells-460-480W-All-Black-Double-Glass-Bifa-047b39a42ff3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +40 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +35 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +30 W, cooler, +2.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +30 W, lighter, +2.7 pp | | [SunKean SKT460M10-120D3](https://comparepv.com/panel/sunkean-skt460m10-120d3) | 460 W | -10 W, -0.5 pp | | [SunKean SKT465M10-120D3](https://comparepv.com/panel/sunkean-skt465m10-120d3) | 465 W | -0.2 pp | | [SunKean SKT475M10-120D3](https://comparepv.com/panel/sunkean-skt475m10-120d3) | 475 W | +0.2 pp | | [SunKean SKT480M10-120D3](https://comparepv.com/panel/sunkean-skt480m10-120d3) | 480 W | +10 W, +0.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +90 W, cooler, +3.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +85 W, cooler, +2.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +80 W, lighter, +2.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +70 W, cooler, +2.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +70 W, cooler, +2.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +75 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/sunkean-skt470m10-120d3 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
