The use of **HJT** technology and the **half-cut** design helps to minimize losses and improve efficiency, especially under partial shading and uneven soiling. In practice, this means more predictable energy production in residential and commercial installations, where conditions are often far from ideal. A key feature is the **double-glass** construction, which increases resistance to environmental factors and supports longer, more reliable operation - especially important in rooftop systems exposed to wind, moisture, and temperature fluctuations. Furthermore, the modules are **bifacial**, meaning they can also utilize reflected light from the ground, which improves efficiency in situations where every additional percentage of production matters. This is a good option for investors who prioritize durability, high performance, and long-term profitability, whether in micro-installations, on corporate rooftops, or in ground-mounted systems. ## Notable figures - Efficiency of 22.8% is 0.6pp above the \*\*HJT 400-450W\*\* median (22.2%) - At 227.9 W/m² power density, this panel generates 6.3 W/m² more per unit area than \*\*HJT 400-450W\*\* median (221.6 W/m²) - Temperature coefficient of -0.26%/°C is 0.02pp worse than \*\*HJT 400-450W\*\* median (-0.24%/°C) - higher losses in summer heat - 83% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #3005 out of 14005 panels for efficiency in the database ## Questions ### What is HJT technology in the SunKean SKT430~450M10-108D5 series, and how does it compare to PERC? HJT (Heterojunction Technology) combines a monocrystalline silicon wafer with thin amorphous silicon layers, enabling module efficiency of around 23%. Compared to standard PERC cells, HJT modules carry a lower temperature coefficient (approx. -0.26%/°C vs. -0.35%/°C), meaning less power loss on hot days. This is the core reason the SKT430~450M10-108D5 series achieves up to 450 W in a relatively compact form factor. ### What warranty comes with the SunKean SKT430~450M10-108D5 panels, and what does it cover? The manufacturer provides a 15-year product warranty covering materials and workmanship, plus a 30-year linear power warranty for the SKT430~450M10-108D5 series. The power warranty guarantees the module retains a specified output level — typically above 87.4% of rated power — over three full decades. The 30-year power guarantee is among the longest available in the residential and commercial PV market. ### Are SunKean SKT430~450M10-108D5 panels suitable for pitched roofs with chimneys or dormers? Yes, the SKT430~450M10-108D5 series is compatible with standard racking systems for pitched roofs. The half-cut cell layout splits each cell in two, so partial shading from a chimney or dormer has a reduced impact on total string output. The double-glass construction withstands mechanical loads up to 5,400 Pa, ensuring structural stability under high wind and snow accumulation. ### How does bifacial generation work on the SunKean SKT430~450M10-108D5, and how much additional energy does the rear side contribute? The bifacial design of the SKT430~450M10-108D5 series allows simultaneous energy generation from both the front and rear surfaces. Light reflected from the ground — gravel, concrete, white roofing membrane, or snow — can boost rear-side yield by 7–30%, depending on ground albedo and mounting clearance height. Ground-mount and flat-roof installations typically see the highest bifacial gain because the rear side has unobstructed access to reflected irradiance. ### Do SunKean SKT430~450M10-108D5 panels perform well in winter and overcast conditions? Yes. HJT technology delivers superior low-light performance compared to standard PERC or monoPERC cells, resulting in higher yield on cloudy days and during morning or evening hours. The low temperature coefficient (~-0.26%/°C) also means that in cold weather the module can momentarily exceed its rated power. The sealed double-glass encapsulation protects the cells from moisture ingress and freeze-thaw cycles. ### Which inverters are compatible with SunKean SKT430~450M10-108D5 panels, and how should I size a string? The SKT430~450M10-108D5 modules, with an MPP voltage of approximately 34–36 V and a short-circuit current of around 13 A, are compatible with most mainstream MPPT inverters including SMA, Fronius, Huawei, and SolarEdge. When designing the system, verify the inverter's MPPT input voltage range and size each string so that the open-circuit voltage at minimum expected temperature does not exceed the inverter's maximum DC input rating. ## 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 | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, lighter, +1.7 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, lighter, +1.7 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +1.5 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, lighter, +1.5 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +1.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, lighter, +1.5 pp | | [SunKean SKT345M10](https://comparepv.com/panel/sunkean-skt345m10) | 345 W | -100 W, -5.1 pp, -5 yr warranty | | [SunKean SKT350M10](https://comparepv.com/panel/sunkean-skt350m10) | 350 W | -95 W, -4.9 pp, -5 yr warranty | | [SunKean SKT355M10](https://comparepv.com/panel/sunkean-skt355m10) | 355 W | -90 W, -4.6 pp, -5 yr warranty | | [SunKean SKT360M10](https://comparepv.com/panel/sunkean-skt360m10) | 360 W | -85 W, -4.4 pp, -5 yr warranty | | [SunKean SKT365M10](https://comparepv.com/panel/sunkean-skt365m10) | 365 W | -80 W, -4.1 pp, -5 yr warranty | | [SunKean SKT385M10](https://comparepv.com/panel/sunkean-skt385m10) | 385 W | -60 W, hotter, -3.0 pp | | [SunKean SKT390M10](https://comparepv.com/panel/sunkean-skt390m10) | 390 W | -55 W, hotter, -2.8 pp | | [SunKean SKT395M10](https://comparepv.com/panel/sunkean-skt395m10) | 395 W | -50 W, hotter, -2.6 pp | | [SunKean SKT400M10](https://comparepv.com/panel/sunkean-skt400m10) | 400 W | -45 W, hotter, -2.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/sunkean-skt445m10-108d5 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.
