Two of the three peer comparables - REC Alpha Pro M and Jinko EAGLE G7B - offer bifacial variants with additional energy yield from reflected light, making them more attractive for ground-mount and commercial installations. - **Efficiency trails segment leader** - Maximum efficiency of 22.93% falls short of the flagship Jinko Solar EAGLE G7B (23.69%) by about 0.76 pp, meaning a slightly lower installed power for the same roof area. ## About this series The LUXNERI N5 series from Luxen Solar Energy is engineered to maximize energy yield even under challenging irradiance conditions. At the heart of the series is **N-TOPCon technology** paired with proprietary LECO optimization, which enhances cell performance under low or diffuse light, keeping the panels productive on cloudy days and during early morning or evening hours. The use of **half-cut cells with SMBB (multi-busbar) technology** reduces resistive losses and improves the module's mechanical resistance to microcracks, translating into a longer installation lifespan. The dual-sided, **bifacial design** captures light reflected from the ground, boosting overall energy production without requiring extra roof space. The panels also stand out with a low LID degradation rate and high resistance to PID and hot-spot effects, making them a reliable choice for long-term operation. The sleek, **elegant Full Black version** makes the N5 series a great fit for residential rooftops and plug-in micro-installations, where both performance and appearance matter. It's a solution for investors seeking a balance between aesthetics, durability, and real-world energy production under the variable weather conditions typical of Poland. ## Notable figures - Efficiency of 22.0% matches the \*\*N-type 450-500W\*\* median - 220.3 W/m² power density is 4.8 W/m² below \*\*N-type 450-500W\*\* median (225.2 W/m²) - requires larger installation area - At -0.29%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - At 27.8 kg (4.1 kg above \*\*N-type 450-500W\*\* median of 23.7 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is N-TOPCon and LECO technology in LUXNERI N5 panels? N-TOPCon is an advanced N-type cell technology that reduces energy losses and delivers higher efficiency than conventional P-type cells. The patented LECO solution further optimizes cell performance under low or diffuse light, so LUXNERI N5 panels generate more energy on cloudy days and during early morning and late afternoon hours when irradiance is lower. ### What warranty comes with LUXNERI Series N5 panels? Luxen Solar Energy provides a 20-year product warranty and a 30-year power output warranty. This means the panel maintains a guaranteed performance level for three decades, while manufacturing or material defects are covered for 20 years, giving investors long-term security for their installation. ### What is the maximum power output of the LUXNERI N5 panel and who is it suited for? Panels in the LUXNERI N5 series reach up to 640 Wp, meaning fewer modules are needed to achieve a given system size. This makes the series suitable both for larger installations on single-family home roofs and for plug-in microinstallations, where high efficiency within limited surface area matters most. ### How do half-cut SMBB cells differ from standard solar cells? Half-cut cells are cut in half, which reduces resistive losses and increases mechanical resistance to microcracks. SMBB, or multi-busbar technology, further improves current collection across the cell surface and lowers the risk of power loss from partial shading, such as from chimneys or antennas on the roof. ### Are LUXNERI N5 panels resistant to LID degradation and PID effect? Yes, the LUXNERI N5 series features a low LID degradation rate, meaning minimal light-induced power loss during the initial operating period, along with high resistance to PID, or potential-induced degradation, and the hot-spot effect. These properties support stable energy production throughout the 30-year power warranty period. ### Is the Full Black version of LUXNERI N5 panels a good choice for a single-family home roof? The Full Black version combines aesthetics with the full technical performance of the N5 series, blending seamlessly with dark roofing typical of residential buildings. It is a strong choice for investors who value a uniform, elegant look visible from street level or neighboring properties, in addition to energy production. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/490-510W_ND_33mm_FB_G12R_1961_1134mm_LNDB-23d7d9054002.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +2.5 pp | | [Luxen Solar Energy LNDB-495ND](https://comparepv.com/panel/luxen-solar-energy-lndb-495nd) | 495 W | +0.2 pp | | [Luxen Solar Energy LNDB-500N](https://comparepv.com/panel/luxen-solar-energy-lndb-500n) | 500 W | +10 W, lighter, +0.4 pp | | [Luxen Solar Energy LNDB-505N](https://comparepv.com/panel/luxen-solar-energy-lndb-505n) | 505 W | +15 W, lighter, +0.7 pp | | [Luxen Solar Energy LNDB-510N](https://comparepv.com/panel/luxen-solar-energy-lndb-510n) | 510 W | +20 W, lighter, +0.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +70 W, cooler, +2.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +65 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +60 W, lighter, +2.4 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +50 W, lighter, +2.4 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +50 W, lighter, +2.4 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/luxen-solar-energy-lndb-490nd 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.
