This significantly extends the investment safety horizon compared to typical segment offers. - **22.61% efficiency, above peer comparables** - The 435W variant reaches 22.61% efficiency, surpassing comparable N-type TOPCon modules: Lina Energy LEPV 108 Nexa (22.26%), SunLink SL5N108 (22.3%), and SunKean SKT415-435 (22.27%) at the same maximum power. - **Bifacial glass-glass TOPCon construction** - Combining N-type TOPCon cells with a double-glass build delivers lower LID/LeTID degradation, a better temperature coefficient, and additional energy yield from reflected light (albedo) on bright roof surfaces. - **German manufacturer, established 2007** - Luxor Solar has operated since 2007 out of Germany, reflecting a mature quality process and a consistent aesthetic (White Mesh + Black Frame) attractive for both residential and commercial installations. ## Cons - **Production discontinued (2022-2024)** - The series was manufactured from 2022 to 2024 and has since been discontinued. This means limited module availability for extending existing installations and potential difficulties with long-term warranty servicing. - **No BNEF Tier 1 status** - Luxor Solar does not appear on the BloombergNEF Tier 1 manufacturer list, which may restrict bank financing for commercial projects requiring modules from bankable-tier suppliers, despite solid technical specifications. - **Lower efficiency on base variant** - The lowest-power variant in the series (415W) reaches only 21.58% efficiency, clearly below comparable peer modules (22.26-22.3% at max power) - matching competitor performance requires selecting the higher 425-435W variants. ## About this series The Luxor Solar ECO LINE N-TYPE TOPCON GLASS-GLASS BIF (M108 / 415-435W, White Mesh, Black Frame) series consists of modules designed for stable, long-term operation - combining the **glass-glass** architecture with **bifacial** **N-type TOPCon** solar cells, allowing them to maintain high efficiency over time and under more challenging temperature conditions. The double-glass construction enhances mechanical strength and increases the security of the investment where durability and predictable energy yields are crucial. Bifaciality helps "recover" energy from reflected light, which effectively supports production in installations on bright roofs, with proper mounting, and in locations with good reflectivity. Another key feature is the combination of **White Mesh** with **Black Frame** - the design remains modern, and the module looks lightweight and consistent on the roof. This is a good choice for homeowners who are aware of energy efficiency and for commercial properties where reliability, stable parameters, and better energy balance from the same surface are important. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 215.1 W/m² is 5.1 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Bifaciality factor of 77% can add 4-12% extra yield with reflective mounting surface - #7048 for efficiency, #6152 for temperature performance out of 14129 panels ## Questions ### How does TOPCon N-type technology differ from PERC cells in the Luxor ECO LINE M108 BIF series? The TOPCon N-type cells used in the ECO LINE M108 BIF series have no light-induced degradation (LID) and a better temperature coefficient than PERC cells. In practice, this means higher energy output on hot summer days and a slower long-term power decline. The 30-year linear power warranty is achievable precisely because of the greater stability inherent to N-type cell technology. ### What does bifaciality actually deliver in the Luxor ECO LINE M108 TOPCon modules, and when does it pay off? Bifacial modules generate electricity from both the front glass and the rear glass by capturing light reflected off the surface below. Real-world energy gains (4-15%) depend on surface albedo and mounting height. The biggest benefits occur on light-colored gravel ballast, white roofing membranes, or ground-mounted systems with sufficient clearance. On dark roof tiles, the rear-side contribution is minimal. ### What is the warranty on the Luxor Solar ECO LINE N-TYPE TOPCon Glass-Glass BIF 415-435W panels? Luxor Solar provides a 30-year product warranty and a 30-year linear power warranty. After 30 years of operation, the module is guaranteed to retain at least 89% of its rated power. Both warranties are issued by Luxor Solar, headquartered in Germany. Keep your purchase invoice and installation documentation, as they are required for any warranty claims. ### What does the glass-glass construction offer in the Luxor ECO LINE M108 series, and is the module heavier than a standard panel? The glass-glass design replaces the rear backsheet with a second tempered glass pane, significantly improving resistance to moisture ingress, UV exposure, and mechanical stress. The module is slightly heavier than frameless backsheet alternatives (approx. 26-28 kg) and requires checking roof load capacity and using appropriate mounting hardware. In return, you get markedly longer service life and reduced moisture-driven degradation over the decades. ### Do the Luxor ECO LINE N-TYPE TOPCon Glass-Glass BIF panels (White Mesh, Black Frame) look good on a residential rooftop? Yes, the combination of a white mesh cell pattern with a black anodized frame creates a modern, high-contrast aesthetic. The module looks visually lighter than a Full Black variant while avoiding the plain look of standard silver-framed panels. This design is appreciated in residential prosumer installations where the appearance of the roof surface matters to the homeowner. ### Is the Luxor Solar ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 415-435W series still available for purchase? The ECO LINE N-TYPE TOPCon Glass-Glass BIF series in the White Mesh / Black Frame variant with 415-435W output has been discontinued. Individual units may still be available from distributors drawing down existing stock, but regular supply has ended. Before ordering, confirm availability with your supplier and check whether a newer ECO LINE variant offers comparable specifications. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lx-el-n-type-gg-bif-bw-m108-415-435w-182-en-9b60db6a94d5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +45 W, lighter, +2.0 pp | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | +45 W, cooler, +2.0 pp | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +50 W, +1.9 pp, +10 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +1.8 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +40 W, cooler, +1.8 pp | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +1.8 pp | | [Luxor Solar LX-395M/182-108+](https://comparepv.com/panel/luxor-solar-lx-395m-182-108) | 395 W | Hotter, -1.3 pp, -5 yr warranty | | [Luxor Solar LX-400M/182-108+](https://comparepv.com/panel/luxor-solar-lx-400m-182-108) | 400 W | Hotter, -1.1 pp, -5 yr warranty | | [Luxor Solar LX-405M/182-108+](https://comparepv.com/panel/luxor-solar-lx-405m-182-108) | 405 W | Hotter, -0.8 pp, -5 yr warranty | | [Luxor Solar LX-410M/182-108+](https://comparepv.com/panel/luxor-solar-lx-410m-182-108) | 410 W | Hotter, -0.5 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +90 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +75 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +85 W, cooler, +2.9 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +85 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +70 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +80 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/luxor-solar-lx-420m-182-108-gg Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
