The use of **monocrystalline cells in N-type TOPCon technology** helps maintain stable performance in hot weather and improves production under less sunlight, which translates directly into higher self-consumption in Polish conditions. A key feature of this series is **a 96-cell configuration in M12 format**, which simplifies the construction of efficient strings without compromising the choice of the inverter. The module design focuses on **high resistance to degradation over time**, making it easier to plan the long-term profitability of the installation. An additional advantage is **resistance to PID effects**, which is important where long-term reliability is crucial. This is a good choice for residential and commercial installations, especially on roofs with complex geometries and in projects where longevity and predictable production are important. ## Notable figures - Efficiency of 22.8% matches the \*\*HJT 450-500W\*\* median - At 227.7 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 - 21.5 kg weight - 1.5 kg lighter than \*\*HJT 450-500W\*\* median (23.0 kg), reducing installation effort - 85% bifaciality enables rear-side power generation, boosting yield by 4-13% on reflective surfaces ## Questions ### What is HJT technology in the SunKean SKT440~460M12-96D4 series and is the premium worth it? HJT (Heterojunction Technology) sandwiches an amorphous silicon layer around a monocrystalline cell, achieving roughly 23% module efficiency and a low Pmax temperature coefficient of about -0.24%/°C — better than standard PERC cells. In practice this means smaller power losses on hot days and higher output under diffuse light, both of which translate into a measurably higher annual energy yield per square meter of roof space. ### What warranty does the SunKean SKT440~460M12-96D4 series carry? The SKT440~460M12-96D4 series comes with a 15-year product warranty covering manufacturing defects and a 30-year linear power output warranty. The long power guarantee lets you model the ROI and payback period with confidence, without the risk of unexpected degradation during the repayment period of a solar loan. ### Are the SKT440~460M12-96D4 panels bifacial, and what real-world gain can I expect on a residential roof? Yes, the SKT440~460M12-96D4 is a bifacial double-glass module. The rear side captures irradiance reflected from the substrate or a light-colored roofing membrane, potentially boosting annual yield by 5–15% over a monofacial module. On a typical pitched roof with dark tiles the gain will be modest; on a ground-mount or light-colored surface it can be significant. Actual gain depends on substrate albedo and tilt angle. ### Is the M12 96-cell layout of the SunKean SKT460M12-96D4 compatible with popular inverters? The 96-cell M12 (210 mm) layout enables flexible string design that fits the MPPT input range of most popular string inverters including SMA, Fronius, Huawei, and Solis. A typical string of 10–14 modules produces a Vmpp well within the input specs of standard three-phase inverters. Always verify Voc and Vmp against the inverter datasheet — especially the low-temperature Voc limit — before finalizing the BoS design. ### How does the SunKean SKT440~460M12-96D4 series perform in winter and under overcast skies? HJT technology inherently performs better under low-irradiance conditions than PERC, which matters in climates with frequent cloud cover. The low temperature coefficient also means the modules hold output better on hot summer days compared to conventional silicon cells. Combined, these characteristics deliver more consistent energy production across all seasons. ### Which installations benefit most from the SunKean SKT440~460M12-96D4 series — residential or commercial? Both. The high 460 Wp unit power reduces the total panel count needed to reach a target system size, cutting installation labor and BoS wiring costs. This is especially valuable on rooftops with limited or geometrically complex surface area. The 30-year power warranty and PID resistance make long-term yield forecasting reliable for both residential prosumers and commercial investors calculating LCOE. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1-1-skt440-460m12-96d4-fb-bmg-1-6mm-9d0e053f86e0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, +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, +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, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, +1.7 pp | | [SunKean SKT440M12-96D4](https://comparepv.com/panel/sunkean-skt440m12-96d4) | 440 W | -15 W, -0.8 pp | | [SunKean SKT445M12-96D4](https://comparepv.com/panel/sunkean-skt445m12-96d4) | 445 W | -10 W, -0.5 pp | | [SunKean SKT450M12-96D4](https://comparepv.com/panel/sunkean-skt450m12-96d4) | 450 W | -0.2 pp | | [SunKean SKT460M12-96D4](https://comparepv.com/panel/sunkean-skt460m12-96d4) | 460 W | +0.2 pp | | [SunKean SKT465M12-96D3](https://comparepv.com/panel/sunkean-skt465m12-96d3) | 465 W | +10 W, hotter, +0.5 pp | | [SunKean SKT470M12-96D3](https://comparepv.com/panel/sunkean-skt470m12-96d3) | 470 W | +15 W, hotter, +0.8 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/sunkean-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.
