The use of **double-glass construction** improves resistance to environmental factors and microcracks, which directly translates into predictable energy production in installations exposed to large temperature variations and wind and snow loads. The variants in this series also utilize **bifacial architecture**, allowing them to recover additional energy from reflected light - a significant advantage on bright roofs, on gravel-covered roofs, and in ground-mounted installations. The **multi-cell design** also supports better performance under partial shading and reduces resistive losses. This is a good choice for installers and investors who want to combine the aesthetics of the black version with the durability and reliability of the parameters in residential and commercial projects. ## Notable figures - At 21.0% efficiency, this panel is 1.0pp below the \*\*TOPCon 400-450W\*\* median of 22.0% - At 210.0 W/m², this panel generates 10.2 W/m² less per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 21.0 kg is typical for \*\*TOPCon 400-450W\*\* panels - Ranked #9758 out of 14005 panels for efficiency in the database ## Questions ### What is TOPCon technology and why does the SunKean SKT410~430M10-108D4 series use it? TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type cell technology that delivers higher efficiency and lower recombination losses compared to mainstream PERC cells. In the SKT410~430M10-108D4 series this translates to a maximum power output of 430 Wp, module efficiency of 21–22%, and a low Pmax temperature coefficient of just -0.29%/°C. The result is better performance on hot days and reduced degradation over the full 30-year service life. ### What warranty does the SunKean SKT410~430M10-108D4 come with? The SKT410~430M10-108D4 series is backed by a 15-year product warranty covering material and workmanship defects. SunKean also provides a 30-year linear power warranty, guaranteeing the panel retains at least 87.4% of its rated output over three decades of operation. This is among the more comprehensive warranty packages available for double-glass TOPCon modules in this power class. ### Is the SKT410~430M10-108D4 bifacial, and when does bifaciality actually increase yield? Yes, all variants in this series feature a bifacial architecture, generating power from both the front and rear sides. Rear-side gain is meaningful wherever reflected light is available: light-colored rooftops, gravel ballast on flat roofs, or ground-mount systems over pale soil or concrete. Under favorable conditions the bifacial effect can add several to over ten percent of annual yield compared to a standard monofacial module. ### Are SunKean SKT410~430M10-108D4 panels suitable for a residential pitched roof? Yes. The modules measure 1722×1134×30 mm and weigh approximately 21 kg, which is a standard footprint for 108-cell panels — fully compatible with typical racking systems on tile or standing-seam metal roofs. The 410–430 Wp power range means fewer panels are required to reach the target system capacity, a practical advantage on roofs with limited usable area. ### How does the double-glass construction of the SKT410~430M10-108D4 differ from standard backsheet panels? Instead of a polymer backsheet, the SKT410~430M10-108D4 uses a second 1.6 mm glass layer on the rear. Glass is harder and significantly more resistant to mechanical damage, moisture ingress, and UV degradation than backsheet film. This reduces the risk of microcracks and PID degradation — particularly important in installations exposed to large temperature swings, heavy snow loads, and high wind pressure — directly supporting long-term output stability. ### How does the SunKean SKT410~430M10-108D4 series perform under partial shading or low-irradiance conditions? The SKT410~430M10-108D4 uses a 16-busbar half-cut cell layout, which divides each cell into smaller electrical segments. Shading one section of the array therefore causes a much smaller drop in string output than with conventional full-cell designs. N-type TOPCon cells also exhibit superior low-light response compared to PERC, which has real-world significance in climates with frequent overcast conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1-3-182mm-16BB-108Cells-410-430W-All-Black-Double-Glass-Bifa-537d307daa67.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, hotter, +2.6 pp | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, heavier, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | +45 W, heavier, +2.3 pp | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, +2.3 pp, -5 yr warranty | | [SunKean SKT345M10](https://comparepv.com/panel/sunkean-skt345m10) | 345 W | -65 W, -3.3 pp, -5 yr warranty | | [SunKean SKT350M10](https://comparepv.com/panel/sunkean-skt350m10) | 350 W | -60 W, -3.1 pp, -5 yr warranty | | [SunKean SKT355M10](https://comparepv.com/panel/sunkean-skt355m10) | 355 W | -55 W, -2.8 pp, -5 yr warranty | | [SunKean SKT360M10](https://comparepv.com/panel/sunkean-skt360m10) | 360 W | -50 W, -2.6 pp, -5 yr warranty | | [SunKean SKT365M10](https://comparepv.com/panel/sunkean-skt365m10) | 365 W | -45 W, -2.3 pp, -5 yr warranty | | [SunKean SKT385M10](https://comparepv.com/panel/sunkean-skt385m10) | 385 W | -25 W, hotter, -1.2 pp | | [SunKean SKT390M10](https://comparepv.com/panel/sunkean-skt390m10) | 390 W | Hotter, heavier, -1.0 pp | | [SunKean SKT395M10](https://comparepv.com/panel/sunkean-skt395m10) | 395 W | Hotter, heavier, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | --- Source: https://comparepv.com/panel/sunkean-skt410m10-108d4 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.
