The use of advanced **N-type cell technology** almost completely eliminates the problem of light-induced degradation (LID), guaranteeing stable and high power output from the first day of operation. Thanks to its innovative silicon structure, this series performs much better in the demanding conditions of the Polish climate, offering **above-average efficiency in low sunlight**, which is crucial during the autumn-winter months. They solve the problem of efficiency loss on hot days thanks to a **low temperature coefficient**, allowing for the generation of more electricity in full sun compared to standard modules. They are designed for both conscious prosumers and commercial investors looking for **minimal annual power loss** and long-term reliability confirmed by an extended warranty. What distinguishes SunKean SKE N-type from the competition is the harmonious combination of high power density with **exceptional mechanical resistance** to extreme weather conditions. By choosing this series, you are investing in the technology of the future, which optimizes the return on investment through the highest energy conversion efficiency currently available on the market. ## Notable figures - Efficiency of 19.4% is 3.4pp above the \*\*TOPCon 0-400W\*\* median (16.0%) - 194.2 W/m² power density - 34.4 W/m² more than \*\*TOPCon 0-400W\*\* median (159.8 W/m²), more power per roof area - At -0.29%/°C, hot weather performance is typical for \*\*TOPCon 0-400W\*\* panels - Weight of 12.0 kg (11.5 kg below \*\*TOPCon 0-400W\*\* median of 23.5 kg) allows easier transport and roof mounting - #12727 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### How do SunKean SKE N-type panels compare to standard PERC modules? The SKE N-type series uses TOPCon cells on an N-type silicon substrate, which virtually eliminates light-induced degradation (LID). Compared to mainstream PERC panels, N-type TOPCon cells deliver higher conversion efficiency, better performance at elevated temperatures, and slower long-term power loss. In practice, this means more kilowatt-hours from the same roof area over the entire 30-year power warranty period. ### What warranty does the SunKean SKE N-type come with, and what does it cover? The manufacturer provides a 12-year product warranty covering material defects and workmanship, plus a 30-year linear power output warranty. The power warranty guarantees the panel will produce at least a specified minimum output for three decades. This exceeds the 25-year standard found on most PERC modules and is especially relevant for commercial projects with long investment payback horizons. ### Do SunKean SKE N-type panels perform well during Polish winters and overcast conditions? Yes. TOPCon cells in the SKE N-type series show above-average sensitivity to diffuse irradiance, which is typical of Polish autumn and winter skies. N-type technology maintains higher efficiency under low-light conditions than PERC modules of the same rated power. The low temperature coefficient also means reduced losses on hot summer days when panel surface temperatures exceed 50–60°C. ### What is the rated wattage of the SunKean SKE N-type and what installations is it suited for? The maximum peak power is 175 Wp, placing this series in the smaller monocrystalline module segment. These panels are designed for installations with limited mounting space, roofs with low load-bearing capacity, or off-grid and hybrid systems requiring flexibility. Thanks to TOPCon technology, every watt is converted more efficiently than in older PERC modules of the same nominal power. ### Are SKE N-type panels bifacial, and can they be installed on ground mounts or pergolas? No, the SKE N-type series consists of monofacial modules — they do not harvest light reflected from the ground. They can be installed on pitched roofs, flat roofs with ballast systems, ground-mount structures, or pergolas, provided compatible racking is used. The absence of bifacial technology does not affect front-side efficiency, which remains high thanks to the TOPCon cell architecture. ### How fast do SunKean SKE N-type panels degrade over years of operation? Thanks to TOPCon cells and the elimination of LID, annual power degradation stays below 0.5% — better than PERC modules, which typically degrade at 0.55–0.7% per year. After 30 years, the panel should retain at least the minimum output guaranteed under the linear power warranty. This is a key economic argument for choosing this series over cheaper, older-generation modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/ske175n2-22-798ee64652b2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M150W](https://comparepv.com/panel/gamko-new-energy-gka182m150w) | 150 W | -25 W, lighter, +3.6 pp | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | -15 W, lighter, +3.6 pp | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | Lighter, +3.6 pp | | [Gamko New Energy GKA182M200W](https://comparepv.com/panel/gamko-new-energy-gka182m200w) | 200 W | +25 W, lighter, +3.6 pp | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | -40 W, lighter, +3.6 pp | | [JA Solar NS-220MH-80](https://comparepv.com/panel/ja-solar-ns-220mh-80) | 220 W | +45 W, +2.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-220MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-220mh-80) | 220 W | +45 W, +2.6 pp, -5 yr warranty | | [JA Solar NS-210MH-80](https://comparepv.com/panel/ja-solar-ns-210mh-80) | 210 W | +35 W, +1.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-210MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-210mh-80) | 210 W | +35 W, +1.6 pp, -5 yr warranty | | [IBC Solar YH215W-21M](https://comparepv.com/panel/ibc-solar-yh215w-21m) | 215 W | +40 W, hotter, +1.4 pp | --- Source: https://comparepv.com/panel/sunkean-ske175n2-22 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
