The 640 Wp top model matches the flagship power output of peer series (REC Alpha Pro M, Jetion JT SRt(B)). - **Tier-1 manufacturer per BloombergNEF** - Luxen Solar Energy has held Tier-1 BNEF status since 2022 and has operated since 2005, easing project financing (bankability) for PV installations built on this series - a key factor for commercial investors. - **Low power temperature coefficient** - A Pmax temperature coefficient of -0.29%/°C limits power losses at high module temperatures, improving performance ratio in installations exposed to strong irradiance and high ambient temperatures. - **Long warranty: 20 years / 30 years power** - A 20-year product warranty combined with a 30-year power warranty retaining a minimum of 87.4% output is a premium-class standard among N-type manufacturers, supporting a lower LCOE over the long investment horizon. ## Cons - **Efficiency trails segment leader** - The maximum efficiency of 23.14% is about 0.55 pp lower than the Jinko Solar EAGLE G7B module (23.69%) at the same 640 Wp max power - a small gap, but noticeable on roofs with limited surface area. - **Shorter Tier-1 track record and production scale** - Luxen has held Tier-1 BNEF status only since 2022, with a targeted production capacity of 10 GW, whereas global peers such as Jinko Solar operate at a far larger, long-established production scale and longer bankability track record. ## About this series The N5 series from Luxen Solar Energy consists of photovoltaic modules built on N-type cells in a **TOPCon** architecture, combining high conversion efficiency with resistance to common PV degradation issues such as light- and voltage-induced degradation. The use of **half-cut cells** along with multi-busbar (SMBB) technology reduces resistive and current losses, allowing the panel to maintain stable output even under partial shading. The **glass-glass** construction in the bifacial version enables additional energy harvest from light reflected off the ground surface, making this series an attractive choice for ground-mount installations, solar farms, and flat roofs where maximizing energy yield per available area is a priority. The panels stand out for their **high PID resistance** and low power temperature coefficient, resulting in better performance in high-temperature conditions and a stable performance ratio throughout the module's lifetime. The N5 series is aimed at both commercial investors and installers seeking a solution with low levelized cost of energy (LCOE) per kWp, while maintaining a robust mechanical build and long module lifespan. ## Notable figures - At 22.5% efficiency, this panel is 0.6pp above typical \*\*N-type 400-450W\*\* modules (median: 21.9%) - At 225.3 W/m² power density, this panel generates 7.0 W/m² more per unit area than \*\*N-type 400-450W\*\* median (218.3 W/m²) - At -0.29%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - At 20.8 kg, this panel is 1.2 kg lighter than \*\*N-type 400-450W\*\* median (22.0 kg) - easier handling during installation - Ranked #3982 out of 14005 panels for efficiency in the database ## Questions ### How does the N5 series differ from panels based on P-type cells? N5 panels use N-type cells in TOPCon architecture, which offer higher base efficiency and practically no light-induced degradation (LID), common in older P-type cells. As a result, the module loses less power in the first year of operation and maintains higher energy yield throughout the 30-year power warranty period. ### What is the maximum power output of a Luxen N5 series panel? The most powerful variant in the N5 series reaches up to 640 Wp. This high unit power comes from half-cut cells and multi-busbar (SMBB) technology, which reduce current losses and deliver more energy from the same module surface — especially valuable when designing PV farms and large flat roofs. ### What warranty comes with Luxen LUXPOWER N5 panels? The manufacturer provides a 20-year product warranty and a 30-year power performance warranty. This covers both material and workmanship defects, as well as guaranteed power output retention over a long period — a standard offered by tier 1 manufacturers like Luxen Solar Energy. ### Are N5 panels suitable for solar farms and flat roof installations? Yes, the glass-glass construction and high PID resistance make the N5 series well suited for ground-mount installations and flat roofs, where modules face longer sun exposure and harsher operating conditions. A low power temperature coefficient also ensures stable performance at the high module temperatures typical of summer PV farms. ### What is PID resistance and why does it matter for N5 panels? PID (potential-induced degradation) is a power loss phenomenon caused by voltage differences between cells and the frame or grounding, common in large string installations. N5 panels offer high PID resistance, reducing the risk of performance decline over time and delivering higher, more predictable energy yield throughout the system's lifetime. ### Is Luxen Solar Energy a reliable PV panel manufacturer? Luxen Solar Energy is a tier 1 manufacturer headquartered in China, meeting the strict financial and production criteria used to classify the largest, most stable module makers. Tier 1 status also facilitates bank financing for projects and provides greater assurance regarding future warranty service availability. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/420-440W_N_33mm_M10_1722_1134mm_LNVB-313d6a742813.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, heavier, +1.8 pp | | [Luxen Solar Energy LNVB-415N](https://comparepv.com/panel/luxen-solar-energy-lnvb-415n) | 415 W | -25 W, -1.3 pp | | [Luxen Solar Energy LNVB-420N](https://comparepv.com/panel/luxen-solar-energy-lnvb-420n) | 420 W | -20 W, -1.0 pp | | [Luxen Solar Energy LNVB-425N](https://comparepv.com/panel/luxen-solar-energy-lnvb-425n) | 425 W | -15 W, -0.8 pp | | [Luxen Solar Energy LNVB-430N](https://comparepv.com/panel/luxen-solar-energy-lnvb-430n) | 430 W | -10 W, -0.5 pp | | [Luxen Solar Energy LNVB-435N](https://comparepv.com/panel/luxen-solar-energy-lnvb-435n) | 435 W | -0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/luxen-solar-energy-lnvb-440n Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
