This translates into a smaller required installation area for the same power output. - **N-type HJT (heterojunction) cells** - HJT technology delivers a lower LID/LETID degradation rate and better efficiency retention at high temperatures than older PERC cells, resulting in higher real-world energy yield over the system's lifetime. - **30-year product and power warranty** - The manufacturer offers 30 years of both product and power warranty - longer than the standard 25 years offered by most competing tier-1 manufacturers, increasing long-term investment security. - **Bifacial generation and transparent glass-glass design** - Bifaciality enables additional energy yield from ground reflection (e.g., bright roofing, gravel), while the transparent, frameless form factor opens up applications unavailable to standard modules - carports, terrace canopies, winter gardens, and semi-transparent facades. - **Enhanced mechanical and thermal durability** - Glass-glass construction instead of standard glass-backsheet improves resistance to moisture, microcracks, and thermal stress, which matters especially in demanding BIPV applications and variable weather exposure. ## Cons - **Manufacturer outside BNEF Tier-1 list** - Luxor Solar does not appear as a Tier-1 manufacturer in BloombergNEF's bankability classification, unlike JA Solar from the peer comparables. This may complicate financing for large-scale projects where banks require this classification. - **Niche transparent/frameless segment - limited production scale** - As a German manufacturer founded in 2007 operating in the niche of transparent glass-glass modules, Luxor Solar has a significantly smaller production scale than global tier-1 giants, which can translate into higher unit pricing and longer lead times compared to mass-market competitor models. ## About this series The Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial (Transparent, Frameless) series is designed for installations where both aesthetics and maximum energy yield are important. The use of **N-Type HJT (heterojunction) solar cells** helps minimize power losses over time and maintain high efficiency even under demanding operating conditions. The **glass-glass** construction enhances mechanical and thermal stability, while also improving the durability of the module compared to typical solutions with a backsheet. A key advantage is **bifacial generation** - the panel can operate from "both sides," providing additional energy gain, for example, over a light surface or in open-air configurations. The **transparent, frameless** design makes the modules ideal for semi-transparent applications: carport canopies, terrace covers, greenhouses, or facades. Carefully designed **edge sealing** enhances resistance to moisture and ensures long-term reliability in installations requiring high levels of dependability. ## Notable figures - 23.1% module efficiency - 0.9pp better than the \*\*HJT 400-450W\*\* median of 22.2% - 227.3 W/m² power density - 5.7 W/m² more than \*\*HJT 400-450W\*\* median (221.6 W/m²), more power per roof area - At -0.24%/°C, hot weather performance is typical for \*\*HJT 400-450W\*\* panels - 92% bifaciality enables rear-side power generation, boosting yield by 5-14% on reflective surfaces - #1683 for efficiency, #13 for temperature performance out of 14005 panels ## Questions ### What types of installations are the Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial frameless panels best suited for? Thanks to their transparent, frameless design and dual-glass construction, these modules excel wherever aesthetics and light transmission matter: carports, terrace canopies, winter gardens, pergolas, and BIPV facades. The manufacturer approves overhead installation, allowing the module to serve directly as a roofing element without a traditional surface underneath. ### What warranty does the Luxor Solar Eco Line N-Type HJT Glass-Glass Bifacial series come with? Luxor Solar provides a 30-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. The manufacturer guarantees the module will maintain its rated efficiency for three full decades. This is among the longest warranty packages currently available for photovoltaic panels on the market. ### What does bifacial energy generation offer in these panels, and how much extra yield can you expect? A bifacial panel harvests irradiance from both the front and rear sides, capturing light reflected from the ground or surroundings. The HJT cells in this series reach up to approximately 95% bifaciality, meaning the rear side performs nearly as efficiently as the front. In installations over bright surfaces such as concrete, sand, or snow, or on open-structure racking, the additional annual energy yield can range from a few to over ten percent. ### Are frameless glass-glass HJT modules harder to install than standard aluminum-framed panels? Installing frameless modules requires dedicated clamp systems or point-fixing hardware designed specifically for glass-glass construction. These panels are heavier than typical glass-backsheet modules, but the dual-glass build provides greater mechanical rigidity. Working with an installer experienced in BIPV systems is recommended to ensure the correct mounting solution is selected and edge sealing integrity is maintained. ### How does HJT technology differ from PERC, and why choose it in the Eco Line N-Type series? HJT (heterojunction) cells combine crystalline silicon with amorphous silicon layers, minimizing carrier recombination and sustaining high efficiency even at elevated temperatures. Compared to PERC, HJT typically offers a lower temperature coefficient (around minus 0.25%/°C vs. minus 0.35%/°C for PERC), resulting in less power loss on hot days. The N-Type substrate also eliminates the LID (Light-Induced Degradation) effect common in P-Type modules. ### Where is Luxor Solar headquartered, and is it a reliable manufacturer with long-term service support? Luxor Solar is headquartered in Stuttgart, Germany, and has been active in the photovoltaic market for over 20 years. The company is not currently listed on the Bloomberg NEF Tier 1 ranking but holds IEC certifications and maintains an established distribution network across Europe. The Eco Line N-Type HJT series is backed by a 30-year product and power warranty, reflecting the manufacturer's confidence in the long-term durability of its modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lx-el-hjt-gg-bif-flt-est-m108-420-440w-182-en-93de1ae4dc1b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, lighter, +1.4 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, lighter, +1.4 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +1.2 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, lighter, +1.2 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, lighter, +1.2 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, lighter, +1.2 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, hotter, +1.2 pp | | [Luxor Solar LX-395M/182-108+](https://comparepv.com/panel/luxor-solar-lx-395m-182-108) | 395 W | Hotter, -2.5 pp, -5 yr warranty | | [Luxor Solar LX-400M/182-108+](https://comparepv.com/panel/luxor-solar-lx-400m-182-108) | 400 W | Hotter, -2.3 pp, -5 yr warranty | | [Luxor Solar LX-405M/182-108+](https://comparepv.com/panel/luxor-solar-lx-405m-182-108) | 405 W | Hotter, -2.0 pp, -5 yr warranty | | [Luxor Solar LX-410M/182-108+](https://comparepv.com/panel/luxor-solar-lx-410m-182-108) | 410 W | Hotter, -1.8 pp, -5 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, +1.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, +1.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, +1.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, lighter, +1.4 pp | --- Source: https://comparepv.com/panel/luxor-solar-lx-440m-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.
