This solution effectively eliminates the problem of rapid light-induced degradation, which translates into significantly higher yield stability over a long-term perspective of use. The greatest advantage of these modules is their **bifacial dual-glass construction**, which not only drastically increases mechanical resistance to extreme weather conditions but also allows for efficient energy harvesting from radiation reflected from the ground. As a result, these panels generate noticeably more electricity than standard monofacial modules, which is particularly evident when installed on bright surfaces. An **excellent temperature coefficient** ensures that this series maintains high efficiency even on hot days, which is a key advantage in optimizing return on investment in the Polish climate. The product was designed for investors seeking a balance between aesthetics and maximum power density on limited roof space. The use of **SMBB (Super Multi-Busbar) technology** further minimizes transmission losses within the cell, making these panels one of the most competitive solutions in the premium segment for modern residential housing and demanding commercial projects. ## Notable figures - At 23.0% efficiency, this panel is on par with typical \*\*HJT 450-500W\*\* modules - At 230.4 W/m² power density, roof space requirements are typical for \*\*HJT 450-500W\*\* panels - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 450-500W\*\* median (-0.24%/°C), expect higher hot weather losses - Bifacial design (82% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #1711 for efficiency, #511 for temperature performance out of 14005 panels ## Questions ### What makes the HJT technology in the Sunket SKT430~450M10-108D5 panels stand out? HJT (Heterojunction Technology) combines the strengths of monocrystalline and thin-film cells. In the SKT430~450M10-108D5 series this translates to a temperature coefficient of -0.24%/°C, significantly better than standard PERC cells at -0.38%/°C. The panels lose far less power on hot summer days, directly boosting annual energy yield and shortening the investment payback period. ### What warranty do the Sunket SKT430~450M10-108D5 panels come with? The manufacturer provides a 15-year product warranty and a 30-year linear power warranty. After year one the panel retains at least 99% of rated output, and after 30 years a minimum of 88% of nominal power. This is one of the strongest warranty packages available in the 450 W HJT module segment. ### Do the bifacial Sunket SKT450M10-108D5 panels actually generate more energy than monofacial modules? Yes. With a bifacial dual-glass construction and bifaciality above 90%, the rear surface can capture up to 90% of the front-side power from light reflected off the ground or facade. The largest energy gains, reaching 10–25%, occur when the modules are mounted above high-albedo surfaces such as white gravel, light concrete, or snow. ### How does the SKT430~450M10-108D5 series handle extreme weather conditions? The dual-glass construction delivers a certified mechanical load resistance of 5400 Pa, accommodating heavy snow loads and strong winds. The modules hold TÜV and CE certifications, include built-in anti-PID protection, and undergo 100% factory quality inspection. This is a meaningful advantage for installations in mountain or coastal locations. ### How many cells does the SKT430~450M10-108D5 module have and what are its dimensions? The SKT430~450M10-108D5 series features 108 half-cut HJT monocrystalline cells in the 182 mm format. The half-cut layout reduces internal thermal losses and improves shade tolerance, for example from chimneys or antennas. At 450 Wp peak output, it is an attractive option for rooftops with limited area where power density per square meter matters. ### Is Sunket New Energy a reputable manufacturer, and what certifications do the SKT430~450M10-108D5 panels carry? The panels are manufactured by Wuxi Sunket New Energy Technology Co., Ltd. based in China. The SKT430~450M10-108D5 series holds TÜV, CE, CEC, ISO, and CQC certifications. The company specializes in HJT technology and backs its modules with a 30-year linear power warranty, reflecting strong confidence in long-term product durability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5HJT-182mm-430-450W-108cells-Double-Glass-Bifacial-Mono-Hal-54f042ade913.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +1.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, lighter, +1.5 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, lighter, +1.5 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, heavier, +1.5 pp | | [Sunket New Energy SKT345M10](https://comparepv.com/panel/sunket-new-energy-skt345m10) | 345 W | -105 W, -5.3 pp, -5 yr warranty | | [Sunket New Energy SKT350M10](https://comparepv.com/panel/sunket-new-energy-skt350m10) | 350 W | -100 W, -5.1 pp, -5 yr warranty | | [Sunket New Energy SKT355M10](https://comparepv.com/panel/sunket-new-energy-skt355m10) | 355 W | -95 W, -4.8 pp, -5 yr warranty | | [Sunket New Energy SKT360M10](https://comparepv.com/panel/sunket-new-energy-skt360m10) | 360 W | -90 W, -4.6 pp, -5 yr warranty | | [Sunket New Energy SKT365M10](https://comparepv.com/panel/sunket-new-energy-skt365m10) | 365 W | -85 W, -4.3 pp, -5 yr warranty | | [Sunket New Energy SKT385M10](https://comparepv.com/panel/sunket-new-energy-skt385m10) | 385 W | -65 W, hotter, -3.2 pp | | [Sunket New Energy SKT390M10](https://comparepv.com/panel/sunket-new-energy-skt390m10) | 390 W | -60 W, hotter, -3.0 pp | | [Sunket New Energy SKT395M10](https://comparepv.com/panel/sunket-new-energy-skt395m10) | 395 W | -55 W, hotter, -2.8 pp | | [Sunket New Energy SKT400M10](https://comparepv.com/panel/sunket-new-energy-skt400m10) | 400 W | -50 W, hotter, -2.5 pp | | [Sunket New Energy SKT405M10](https://comparepv.com/panel/sunket-new-energy-skt405m10) | 405 W | -45 W, hotter, -2.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/sunket-new-energy-skt450m10-108d5 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.
