Instead of installing traditional modules on a support structure, you receive a **integrated, low-profile** solution that helps maintain a consistent roofline and minimize the visibility of the installation from the street. A key advantage of this series is the **N-type solar cells using TOPCon technology**, which are valued for their stable performance and lower susceptibility to energy yield losses over time. In practice, this means more predictable energy production and better tolerance for typical roofing challenges, such as partial shading or roof heating. The SunKean N Type Solar Tile Series is ideal for investors who prioritize aesthetics and integration - in single-family homes, premium buildings, development projects, and renovations, where the appearance of the facade and roof are important. Compared to many other PV roofing tiles, it stands out due to its **emphasis on integration, installation order, and modern architecture**. ## Notable figures - Module efficiency of 16.7% is 2.8pp below average for \*\*N-type 0-400W\*\* panels (median: 19.5%) - At 159.9 W/m², this panel generates 35.0 W/m² less per unit area than \*\*N-type 0-400W\*\* median (194.9 W/m²) - Temperature coefficient of -0.39%/°C is 0.07pp worse than \*\*N-type 0-400W\*\* median (-0.32%/°C) - higher losses in summer heat - Weight of 9.3 kg (12.7 kg below \*\*N-type 0-400W\*\* median of 22.0 kg) allows easier transport and roof mounting - Ranked #13530 out of 14005 panels for efficiency in the database ## Questions ### How does the SunKean N Type Solar Tile differ from conventional rooftop solar panels? The SunKean N Type Solar Tile Series is a BIPV product in which the tile simultaneously serves as a roofing material and an energy source. It requires no separate racking structure or add-on modules. The result is a low-profile, seamless roofline with minimal visual impact from the street — a particularly strong advantage for premium residential projects, new developments, and areas subject to heritage or landscape protection requirements. ### What warranty does the SunKean N Type Solar Tile Series carry? SunKean provides a 12-year product warranty covering material and manufacturing defects, plus a 25-year linear power output warranty. This means the cells maintain their declared efficiency according to SunKean's published degradation schedule for a full quarter century. This warranty scope is consistent with industry standards for N-type TOPCon modules and represents a solid long-term assurance for the investment. ### What is N-type TOPCon technology and why does it matter for a solar roof tile? TOPCon (Tunnel Oxide Passivated Contact) N-type cells deliver a lower annual degradation rate than conventional PERC cells. In practice, this means more stable energy production over time and better tolerance to high roof-surface temperatures and partial shading. For BIPV roof tiles that are permanently integrated into the roof structure and cannot be repositioned easily, these characteristics have a direct and lasting impact on overall system yield. ### What is the power output of a single SunKean N Type Solar Tile, and how many tiles does a typical residential system require? Each SunKean N Type Solar Tile has a maximum power output of 135 Wp. A 5 kWp system requires approximately 37 tiles, while a 10 kWp installation needs around 75 tiles. The exact count depends on available roof area, roof azimuth and tilt, and local irradiance conditions. We recommend requesting a tailored system design from a qualified installer who can account for your specific building layout. ### Is the SunKean N Type Solar Tile suitable for pitched roofs, and what tilt angle is optimal? Yes, the N Type Solar Tile Series is designed specifically for conventional pitched roofs, where it fully replaces standard roofing tiles. Optimal tilt angles are typically between 15° and 45°, which covers the vast majority of residential homes. Before purchasing, consult an installer to evaluate your roof's azimuth relative to south and to design a layout that maximizes annual energy yield for your location. ### How do SunKean N Type Solar Tiles perform under partial shading or overcast conditions? The N-type TOPCon cells used in this series offer better partial-shading tolerance than conventional PERC cells, and their low degradation rate supports more consistent output even on overcast days. Note that this series is not bifacial, so energy is generated exclusively from the front face of each tile. For roofs with localized shading from chimneys or dormers, consult your installer about integrating power optimizers or microinverters to minimize mismatch losses. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/skt135m10-fb-eu-0af961c9bc23.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | +15 W, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | +25 W, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | +45 W, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | Lighter, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | Lighter, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | -35 W, +6.3 pp, +5 yr warranty | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | Lighter, +6.3 pp, +5 yr warranty | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | Cooler, lighter, +4.6 pp | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | Cooler, lighter, +4.6 pp | | [Centro Energy CE-180M60](https://comparepv.com/panel/centro-energy-ce-180m60) | 180 W | +45 W, hotter, +3.8 pp | --- Source: https://comparepv.com/panel/sunkean-skt135m10 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
