A key advantage is the **positive power tolerance**, which means you receive a panel that consistently performs above its declared specifications, making precise installation design easier. The construction with **tempered glass** and a robust frame provides resistance to daily wear and tear and long-term outdoor operation, while **MC4 connectors** speed up assembly and minimize the risk of wiring errors. The use of an **IP68 protected junction box** increases the reliability of operation in humid conditions and during heavy rainfall. This series is a good choice for home installations, small businesses, and projects on commercial buildings, where you expect predictable yields, easy maintenance, and a reasonable balance between quality and cost over the years. ## Notable figures - Efficiency of 17.6% is 1.8pp below the \*\*PERC 0-400W\*\* median (19.4%) - At 176.5 W/m², this panel generates 17.9 W/m² less per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - At -0.36%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - Weight of 23.5 kg is 3.0 kg above \*\*PERC 0-400W\*\* median (20.5 kg) - verify structural support - Ranked #13313 out of 14005 panels for efficiency in the database ## Questions ### Is the Sunlike Solar LUXMAX / LNSF series still available for purchase? The Sunlike Solar LUXMAX / LNSF (72 cells) series has been discontinued and is no longer actively manufactured. Availability is limited to remaining stock held by distributors. If you are specifically looking for this series, check current inventory levels directly with resellers. If it is out of stock, consider newer monocrystalline PERC modules with comparable specs and better long-term parts availability. ### What warranty comes with the Sunlike Solar LNSF 400 W panels? Sunlike Solar LUXMAX / LNSF panels carry a 10-year product warranty covering material defects and workmanship, plus a 25-year linear power output warranty. The positive power tolerance means the module delivers at least its rated output from day one. After 25 years of operation the panel is guaranteed to retain a specified percentage of its nominal 400 Wp, providing a predictable return on investment over the system's lifetime. ### What is PERC technology used in the LNSF series and is it worth choosing? PERC (Passivated Emitter and Rear Cell) is a monocrystalline cell technology that boosts efficiency by reflecting unused light from a passivated rear surface back through the cell for a second absorption pass. In practice this means higher energy yield per square meter compared to standard mono cells. The LUXMAX / LNSF series uses 72 PERC cells to reach up to 400 Wp, making it an efficient choice for residential and small commercial rooftops where available area is limited. ### Do Sunlike Solar LUXMAX LNSF panels perform well in harsh weather — rain, snow, freezing temperatures? Yes, the LNSF series is designed for year-round outdoor use in variable climates. Tempered glass and a robust aluminum frame provide resistance to snow loads and wind pressure common in Central and Eastern Europe. The IP68-rated junction box protects against moisture and heavy rainfall throughout the year. The positive power tolerance ensures the panel meets or exceeds its rated output even during low-irradiance conditions typical of winter months. ### How does the 72-cell format of the LNSF series compare to common 60- or 66-cell panels? The 72-cell format yields a larger module with higher per-unit power — up to 400 Wp for the LUXMAX / LNSF — allowing you to reach your target system size with fewer panels. The trade-off is greater physical size and weight, which requires verifying roof load capacity and rafter spacing. The 72-cell format is best suited to larger roof areas on single-family homes, farm buildings, and light commercial structures where there is sufficient mounting space. ### Are LUXMAX / LNSF panels compatible with MC4 connectors and standard inverters available on the market? Yes, the LUXMAX / LNSF series is equipped with industry-standard MC4 connectors, compatible with the vast majority of string inverters and racking systems available today. MC4 connectors speed up installation and reduce wiring errors on site. Before purchasing, verify that your chosen inverter supports the open-circuit voltage (Voc) and short-circuit current (Isc) of the LNSF modules — these parameters are available in the manufacturer's datasheet or from your reseller. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/g1-series-72-cells-dbc2954f3e4f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | -10 W, lighter, +2.4 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | -20 W, lighter, +2.2 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | -15 W, +2.2 pp, +5 yr warranty | | [Canadian Solar CS3U-395P](https://comparepv.com/panel/canadian-solar-cs3u-395p) | 395 W | +45 W, lighter, +2.2 pp | | [SunLink LNSU-400M](https://comparepv.com/panel/sunlink-lnsu-400m) | 400 W | +50 W, heavier, +2.2 pp | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | -15 W, lighter, +2.1 pp | | [Sunlike Solar LNSF-400M](https://comparepv.com/panel/sunlike-solar-lnsf-400m) | 400 W | +50 W, +2.1 pp | | [Canadian Solar CS3L-365P](https://comparepv.com/panel/canadian-solar-cs3l-365p) | 365 W | +15 W, lighter, +2.1 pp | | [Sunlike Solar LNSF-335P](https://comparepv.com/panel/sunlike-solar-lnsf-335p) | 335 W | -15 W, -0.8 pp | | [Sunlike Solar LNSF-340P](https://comparepv.com/panel/sunlike-solar-lnsf-340p) | 340 W | -10 W, -0.5 pp | | [Sunlike Solar LNSF-345P](https://comparepv.com/panel/sunlike-solar-lnsf-345p) | 345 W | Very close match | | [Sunlike Solar LNSF-355P](https://comparepv.com/panel/sunlike-solar-lnsf-355p) | 355 W | +0.2 pp | | [Sunlike Solar LNSF-380M](https://comparepv.com/panel/sunlike-solar-lnsf-380m) | 380 W | +30 W, +1.5 pp | | [Sunlike Solar LNSF-385M](https://comparepv.com/panel/sunlike-solar-lnsf-385m) | 385 W | +35 W, +1.6 pp | | [Sunlike Solar LNSF-390M](https://comparepv.com/panel/sunlike-solar-lnsf-390m) | 390 W | +40 W, +1.7 pp | | [Sunlike Solar LNSF-395M](https://comparepv.com/panel/sunlike-solar-lnsf-395m) | 395 W | +45 W, +1.9 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +125 W, +6.4 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/sunlike-solar-lnsf-350p Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
