Thanks to the **Bifacial Double Glass** construction, these panels not only absorb direct light but also rays reflected from the ground, significantly increasing the total energy yield from a smaller installation area. This is an ideal solution for limited roof space, offering higher resistance to PID degradation and the LID effect compared to traditional P-type cells. The use of **double tempered glass** guarantees exceptional mechanical strength and protection against harsh weather conditions, such as hail or strong wind, which translates into a longer lifespan for the entire installation. These modules are dedicated to both demanding private investors and commercial projects, where maximizing the return on investment and operational stability over decades is essential. Exceptionally low temperature coefficients allow this series to perform perfectly in full sun, maintaining high efficiency where standard components lose power. By choosing this solution, the user receives **increased performance in low-light conditions**, which is crucial for stable yields in the Polish climate. ## Notable figures - Module efficiency of 21.0% is 1.0pp below average for \*\*TOPCon 400-450W\*\* panels (median: 22.0%) - Power density of 210.0 W/m² is 10.2 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - needs more roof space - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - Weight of 21.0 kg is typical for \*\*TOPCon 400-450W\*\* panels - #9758 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the Sunket SKT410~430M10-108D4 series panels? The SKT410~430M10-108D4 series carries a 15-year product warranty covering material and manufacturing defects, plus a 30-year power output warranty guaranteeing at least 87.4% of rated power over three decades. This places the series among the stronger long-term warranty offerings on the market and reflects the manufacturer's confidence in N-type TOPCon cell durability. ### Do the SKT410~430M10-108D4 panels generate power from both sides, and is bifacial technology worth the extra cost? Yes, this series uses a bifacial double glass construction, meaning the rear side of the module captures light reflected from the ground or rooftop surface. In practice this can increase total energy yield by 5-15% compared to monofacial modules of the same rated power, without requiring additional roof space. The gain is most pronounced over light-colored or reflective surfaces. ### How does the SKT410~430M10-108D4 series perform on hot days and at high operating temperatures? The N-type TOPCon technology used in this series delivers a power temperature coefficient of just -0.29%/°C. Older P-type PERC modules typically reach -0.35%/°C or worse. This means that on hot summer days, when module temperature exceeds 25°C, the SKT series loses significantly less power than a conventional panel, resulting in higher real-world yield during peak irradiance hours. ### Do the SKT410~430M10-108D4 modules perform well under low-light conditions typical of Central European climates? Yes, N-type TOPCon cells show enhanced sensitivity to diffuse irradiance, producing higher output under overcast skies compared to P-type modules. The SKT410~430M10-108D4 series is therefore well suited to climates with frequent cloudy periods, where a significant portion of annual energy generation comes from diffuse light rather than direct beam irradiance. ### Are the SKT410~430M10-108D4 panels resistant to PID and LID degradation? Yes, the N-type TOPCon cell base virtually eliminates the LID (Light-Induced Degradation) effect and provides very high resistance to PID (Potential-Induced Degradation). In conventional P-type panels these effects can reduce output by several percent in the first years of operation. The SKT410~430M10-108D4 series offers substantially better long-term power stability, directly improving the investment's return profile. ### Are Sunket SKT410~430M10-108D4 panels suitable for commercial installations and utility-scale PV plants? Yes, the series is designed for both residential rooftop systems and commercial or ground-mounted PV projects. The 410-430 Wp power range, bifacial double glass construction, and 30-year power warranty meet the requirements of projects focused on maximizing LCOE and achieving stable multi-decade energy yields, making them a viable choice for larger-scale installations. ## 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 | | [Sunket New Energy SKT345M10](https://comparepv.com/panel/sunket-new-energy-skt345m10) | 345 W | -65 W, -3.3 pp, -5 yr warranty | | [Sunket New Energy SKT350M10](https://comparepv.com/panel/sunket-new-energy-skt350m10) | 350 W | -60 W, -3.1 pp, -5 yr warranty | | [Sunket New Energy SKT355M10](https://comparepv.com/panel/sunket-new-energy-skt355m10) | 355 W | -55 W, -2.8 pp, -5 yr warranty | | [Sunket New Energy SKT360M10](https://comparepv.com/panel/sunket-new-energy-skt360m10) | 360 W | -50 W, -2.6 pp, -5 yr warranty | | [Sunket New Energy SKT365M10](https://comparepv.com/panel/sunket-new-energy-skt365m10) | 365 W | -45 W, -2.3 pp, -5 yr warranty | | [Sunket New Energy SKT385M10](https://comparepv.com/panel/sunket-new-energy-skt385m10) | 385 W | -25 W, hotter, -1.2 pp | | [Sunket New Energy SKT390M10](https://comparepv.com/panel/sunket-new-energy-skt390m10) | 390 W | Hotter, heavier, -1.0 pp | | [Sunket New Energy SKT395M10](https://comparepv.com/panel/sunket-new-energy-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/sunket-new-energy-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, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
