This means limited availability of service, spare parts, and warranty support for the KK270P series in Europe. - **Low module efficiency (16.4%)** - At 16.4% efficiency, this module is markedly behind comparable 270 Wp panels - DMEGC (22.9%) and JA Solar/MY Solar (21.2%) - meaning up to ~40% more roof area is needed to achieve the same power output. - **Outdated polycrystalline technology** - The 3-busbar polycrystalline cells lag behind the mono PERC/half-cut technologies used by peer comparables, resulting in lower low-light yield and higher LID degradation compared to newer solutions. ## About this series The Kyocera KK270P series is based on proprietary polycrystalline silicon cell technology, which, thanks to a precise processing method, ensures stable energy yield even under lower sunlight conditions. The precision cell-cutting technology used minimizes the risk of micro-cracks, which translates into real savings throughout the entire lifecycle of the installation. A key design element is the **unique frame structure with water drainage**, which prevents the accumulation of dirt and the formation of dangerous corrosion spots in the module corners. These panels are characterized by exceptional reliability thanks to the use of a **three-layer junction box**, ensuring full tightness and protection of electronics against moisture in extreme weather conditions. This product is dedicated to investors seeking security, for whom the priority is **high resistance to mechanical loads** and operational stability in a variable climate. Compared to competitors, the KK270P model stands out due to its full, vertical integration of the production process - from wafers to finished components - which guarantees rigorous quality control at every stage. The **anti-reflective coating on the glass** used maximizes light absorption, allowing for the efficient use of scattered radiation, making these modules an ideal choice for demanding commercial and residential installations in Polish latitudes. ## Notable figures - At 16.4% efficiency, this panel is 5.4pp below the \*\*database\*\* median of 21.8% - 164.1 W/m² power density is 54.0 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - 19.0 kg weight - 7.5 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - #13584 for efficiency, #13924 for temperature performance out of 14005 panels ## Questions ### Is the Kyocera KK270P series still available for purchase? The KK270P series has been discontinued and is no longer available through regular distribution channels. Kyocera has ended production of this line, so new units may only be found in limited distributor stockpiles. If you are planning a new installation, it is advisable to consider newer Kyocera series or comparable alternatives from other manufacturers that offer active support and guaranteed module availability for future system expansion. ### Do Kyocera KK270P panels perform well in overcast, low-irradiance conditions? Yes. The multicrystalline cells used in the KK270P series are engineered to deliver a stable energy yield under diffuse and low-light irradiance conditions. Kyocera applies an anti-reflective coating to the tempered glass cover, which enhances light absorption even on cloudy days. This makes the modules a reliable choice for Central and Northern European climates where diffuse radiation accounts for a significant share of annual solar resource. ### What is the power output warranty on the Kyocera KK270P? Kyocera backs the KK270P with a 25-year linear power output warranty, guaranteeing that the module will maintain at least a specified percentage of its rated 270 Wp throughout the warranty period. This is considered a premium warranty tier in the PV industry. Since the series is discontinued, prospective buyers should confirm with their local distributor that post-sale warranty service remains active and enforceable. ### Can the Kyocera KK270P handle heavy snow loads on a rooftop in winter? The KK270P series is rated for high mechanical load resistance, making it a solid choice for regions with heavy snowfall. The anodized aluminum frame features a water drainage design that prevents ice and debris buildup in the module corners, reducing stress concentration. The module meets IEC static and dynamic load ratings, allowing installers to confidently specify it for rooftops in high snow-load zones across Central Europe. ### What are the dimensions and weight of the Kyocera KK270P – will it fit a standard pitched roof? The KK270P-3CD3CG measures 1662 × 990 × 46 mm and weighs 19 kg. These are standard 60-cell module dimensions that are fully compatible with most rail-based racking systems designed for pitched roofs. At 19 kg per panel, two installers can handle transport and placement without special lifting equipment. Always verify roof structural load capacity before finalizing system design, especially for larger arrays. ### What is the triple-layer junction box on the KK270P and why does it matter? The triple-layer junction box is the electrical housing mounted on the rear of the module that connects the solar cell strings to the BoS wiring. In the KK270P, its three-stage sealing provides robust IP-rated protection against moisture, dust, and corrosion under harsh weather conditions. This significantly reduces the risk of electrical failure at the cable entry point, contributing to longer trouble-free operation and lower O&M costs over the 25-year system lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5b16491a506ac-c05fffa113a9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Canadian Solar CS3K-320P](https://comparepv.com/panel/canadian-solar-cs3k-320p) | 320 W | +50 W, +2.9 pp | | [Canadian Solar CS3K-315P](https://comparepv.com/panel/canadian-solar-cs3k-315p) | 315 W | +45 W, +2.6 pp | | [SunLink LNSK-320M](https://comparepv.com/panel/sunlink-lnsk-320m) | 320 W | +50 W, heavier, +2.5 pp | | [Canadian Solar CS3K-310P-AG](https://comparepv.com/panel/canadian-solar-cs3k-310p-ag) | 310 W | +40 W, +2.3 pp, +5 yr warranty | | [Rarlon PV Tech RL310HP-120](https://comparepv.com/panel/rarlon-pv-tech-rl310hp-120) | 310 W | +40 W, +2.2 pp | | [SunLink LNSK-315P](https://comparepv.com/panel/sunlink-lnsk-315p) | 315 W | +45 W, heavier, +2.2 pp | | [Canadian Solar CS3K-310PB-AG](https://comparepv.com/panel/canadian-solar-cs3k-310pb-ag) | 310 W | +40 W, +2.0 pp, +5 yr warranty | | [Kyocera KK275P-3CD3CG](https://comparepv.com/panel/kyocera-kk275p-3cd3cg) | 275 W | +0.3 pp | | [Kyocera KK280P-3CD3CG](https://comparepv.com/panel/kyocera-kk280p-3cd3cg) | 280 W | +10 W, +0.6 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | +130 W, +6.2 pp, +15 yr warranty | | [Lina Energy LEPV 400](https://comparepv.com/panel/lina-energy-lepv-400) | 400 W | +130 W, +5.9 pp, +5 yr warranty | | [Phono Solar NS-360MH-60](https://comparepv.com/panel/phono-solar-ns-360mh-60) | 360 W | +90 W, lighter, +5.7 pp | | [PolyCrown Solar Tech NS-360MH-60](https://comparepv.com/panel/polycrown-solar-tech-ns-360mh-60) | 360 W | +90 W, lighter, +5.7 pp | | [Maxeon SPR-MAX3-390-COM](https://comparepv.com/panel/maxeon-spr-max3-390-com) | 390 W | +120 W, +5.7 pp, +15 yr warranty | | [Jshine Solar Technology JS 380~400W 120M6 HJT DG (400W class)](https://comparepv.com/panel/jshine-solar-technology-js-380-400w-120m6-hjt-dg-400w-class) | 400 W | +130 W, +5.6 pp, +5 yr warranty | | [JA Solar JS400 120M6 HJT DG](https://comparepv.com/panel/ja-solar-js400-120m6-hjt-dg) | 400 W | +130 W, +5.6 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/kyocera-kk270p-3cd3cg Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
