For the same roof area, this translates into a genuinely higher energy yield. - **30-year product and 89% power warranty** - Luxor guarantees a 30-year product warranty and a linear power warranty retaining at least 89% output at year 30. This is longer and offers a higher end-of-term floor than, for example, Silfab (25-year product warranty, 82.6% power at year 30) or typical 25-year warranties from PERC-based manufacturers. - **N-type TOPCon plus bifacial glass-glass** - N-type TOPCon cells show lower LID degradation and a better temperature coefficient than PERC, while the bifacial glass-glass construction adds rear-side yield and increases mechanical resistance — per the official datasheet, up to 5400 Pa snow load and 2400 Pa wind load. - **Established EU-based manufacturer** - Luxor Solar has operated since 2007 and is headquartered in Germany, representing over 15 years of manufacturing experience along with compliance with EU quality standards and closer service support for European customers. ## Cons - **Fire safety class C, not A** - Despite marketing copy suggesting 'maximum fire protection class', the official series datasheet lists fire safety class C under IEC 61730, not the highest class A. This can be a meaningful limitation for installations requiring class A, such as roofs near property boundaries or in dense urban settings. - **No BNEF Tier-1 status** - Luxor Solar does not appear on the BloombergNEF Tier-1 list, unlike some comparable manufacturers (e.g., Silfab). This can complicate bank financing for large-scale PV farms, even though the module's technical specs (efficiency, warranty) are competitive. ## About this series Luxor Solar ECO LINE N-TYPE TOPCON GLASS-GLASS BIFACIAL is a series of modules that sets new standards for durability and efficiency in modern PV systems. The use of advanced **N-Type TOPCon cells** allows for a radical reduction in light-induced degradation, which guarantees stable energy production for many years. Thanks to the unique **Glass-Glass** structure, these panels exhibit extreme resistance to mechanical loads and aggressive environmental factors, making them an ideal choice for installations in difficult weather conditions. The **bifacial technology** used enables light absorption from both sides of the module, significantly increasing the total energy yield, especially on bright surfaces. This series solves the problem of efficiency drops at high temperatures, offering an excellent temperature coefficient. It is dedicated to both prosumers focusing on the highest quality and investors building farms with maximum profitability. What distinguishes these modules from the competition is the **maximum fire protection class** and exceptional structural stability, which eliminates the risk of micro-cracks. By choosing this solution, the user gains the certainty of trouble-free operation and higher self-consumption thanks to better performance in diffused light conditions. An innovative anti-reflective coating further increases photon absorption, which translates into real financial savings throughout the entire life cycle of the solar power plant. ## Notable figures - Efficiency of 21.8% matches the \*\*TOPCon 400-450W\*\* median - At 215.1 W/m², this panel generates 5.1 W/m² less per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 24.0 kg (2.0 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What warranty does the Luxor Solar ECO LINE N-TYPE TOPCon Glass-Glass Bifacial series carry? The ECO LINE N-TYPE TOPCon Glass-Glass Bifacial series comes with a 30-year product warranty and a 30-year linear power output warranty. Luxor Solar guarantees at least 89% of nominal output after 30 years of operation. This is among the longest warranty terms in the premium module segment, reflecting the manufacturer's confidence in the combined durability of TOPCon cell technology and glass-glass construction. ### How do N-Type TOPCon cells in the Luxor ECO LINE series compare to standard PERC cells? N-Type TOPCon cells suffer significantly less light-induced degradation (LID) than PERC cells, thanks to a thin silicon-oxide tunneling layer that reduces carrier recombination. This results in a better temperature coefficient — typically around -0.30%/°C versus -0.35%/°C for PERC — meaning lower power losses on hot days and a measurably higher annual energy yield from the same installed capacity compared to an equivalent PERC module. ### Do the bifacial Luxor ECO LINE Glass-Glass panels actually generate more energy on a typical rooftop? Bifacial technology delivers real gains wherever the rear side of the module can capture reflected irradiance — on light-colored roofing membranes, gravel, concrete, or high-albedo grass. On a dark roof surface the rear-side contribution is minimal. The ECO LINE Bifacial series reaches its full potential in ground-mounted systems, carport installations, or flat roofs with white waterproofing, where the additional energy yield can reach 10–20% compared to a monofacial module. ### Why is the glass-glass construction of the Luxor ECO LINE better than a standard rear backsheet? The Glass-Glass design eliminates the rear backsheet entirely, drastically reducing moisture ingress, UV degradation, and delamination risk across the full 30-year service life. An additional benefit is an improved fire classification per IEC 61730, which is increasingly required by insurers for residential and commercial rooftop PV systems. The rigid double-glass structure also eliminates the micro-crack risk associated with thermal warping of conventional backsheet materials. ### Is Luxor Solar a reliable manufacturer, and where are the ECO LINE panels made? Luxor Solar is headquartered in Stuttgart, Germany, and has been active in the photovoltaic market since 2007, with a strong reputation in Central Europe for premium-segment products. Although Luxor is not currently listed on the Bloomberg NEF Tier 1 module manufacturers index, the ECO LINE N-Type series carries IEC certifications and meets European quality standards, ensuring broad acceptance by installers and insurance companies serving residential and utility-scale customers. ### Will a Luxor Solar ECO LINE 430 W panel perform well on a pitched roof with partial shading? Yes. The ECO LINE N-TYPE TOPCon Glass-Glass Bifacial modules use half-cut cells, which split each cell's current into two independent strings. This means partial shading from a chimney, antenna, or dormer window causes a smaller power drop across the entire string than with full-cell modules. To maximize yield under such conditions, pair the panels with an inverter whose MPPT algorithm is optimized for bifacial half-cut module characteristics. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lx-el-n-type-gg-bif-bt-m108-410-430w-182-en-2a4845b165bf.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, lighter, +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 | | [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 | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +80 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/luxor-solar-lx-420-m-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.
