The use of an architecture based on **M10** cells and refined internal connections ensures stable energy production even in less sunny conditions, which is important in Polish weather conditions. The **positive power tolerance** also contributes to this, making the actual start of the installation more favorable than the nominal design assumptions. This is the ideal choice for investors who want to build high-density rooftop and ground-mounted systems - from large homes and farms to commercial buildings. The modules also stand out for their robust operational characteristics, including a sealed **IP68** junction box and glass with an **anti-reflective coating**, which makes it easier to maintain consistent energy yields over time. ## Notable figures - At 21.1% efficiency, this panel is on par with typical \*\*PERC 500-550W\*\* modules - At 211.0 W/m² power density, roof space requirements are typical for \*\*PERC 500-550W\*\* panels - At -0.35%/°C, hot weather performance is typical for \*\*PERC 500-550W\*\* panels - At 30.5 kg, this panel is 2.1 kg heavier than the \*\*PERC 500-550W\*\* median (28.4 kg) - more demanding for installation crews - #9297 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the SunKean SKT530~555M10 series still available for purchase? The SKT530~555M10 series has been officially discontinued, and availability through distributors is very limited. Some dealers may still carry remaining stock, but regular restocking should not be expected. If you are planning a new installation, it is advisable to look at currently manufactured alternatives within SunKean's lineup or comparable modules from other manufacturers. ### What does bifacial mean for the SKT530~555M10, and does it make a difference on a typical rooftop? A bifacial module generates power from both the front and rear surfaces — the back side captures light reflected from the ground or rooftop substrate (e.g., white membrane, gravel, or snow). In Central European climates, the rear-side gain is most noticeable in winter when snow cover increases albedo, potentially boosting output by several percentage points. The actual benefit depends on the albedo of the surface below and the tilt angle of the array. ### What warranties does SunKean provide for the SKT530~555M10 modules? SunKean backs the SKT530~555M10 series with a 15-year product warranty covering defects in materials and workmanship, and a 30-year linear power output warranty. The positive power tolerance means each module is guaranteed to deliver at least its rated wattage at delivery, which improves the energy yield from day one compared to zero-tolerance or negative-tolerance products. ### What does the half-cut PERC technology in the SKT530~555M10 mean in practical terms? Half-cut PERC splits each PERC cell in two, reducing internal resistance and limiting mismatch losses under partial shading — each half-cell operates independently. The M10 cell format (182 mm) enables a module power of up to 555 Wp within a manageable frame size. The result is better performance under variable irradiance conditions and a lower risk of hotspot formation compared to standard full-cell designs. ### What types of installations are the SunKean SKT530~555M10 modules best suited for? The SKT530~555M10 series is well suited to applications where high power density per square meter matters: residential rooftop systems on larger homes, agricultural buildings, commercial warehouses, and ground-mounted agrivoltaic or utility-adjacent arrays. At up to 555 Wp per module, fewer modules are needed to reach a target system size, reducing balance-of-system costs for racking and wiring. ### Does the IP68 junction box on the SKT530~555M10 provide adequate moisture protection? Yes, IP68 is the highest standard ingress protection rating for PV module junction boxes, guaranteeing complete dust-tightness and sustained submersion resistance. For rooftop installations in climates with heavy rain, snow load, and freeze-thaw cycles, an IP68-rated junction box ensures the integrity of electrical connections throughout the module's service life, minimizing the risk of arc faults or corrosion-related degradation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/7-3PERC-182mm-530-555W-144Cells-Double-Glass-Bifacial-Mono-1476bb6ca094.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.4 pp | | [SunKean SKT530M10](https://comparepv.com/panel/sunkean-skt530m10) | 530 W | -15 W, -0.6 pp | | [SunKean SKT535M10](https://comparepv.com/panel/sunkean-skt535m10) | 535 W | -10 W, -0.4 pp | | [SunKean SKT540M10](https://comparepv.com/panel/sunkean-skt540m10) | 540 W | -0.2 pp | | [SunKean SKT550M10](https://comparepv.com/panel/sunkean-skt550m10) | 550 W | Very close match | | [SunKean SKT555M10](https://comparepv.com/panel/sunkean-skt555m10) | 555 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +85 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/sunkean-skt545m10 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
