N-type TOPCon technology delivers lower LID/LeTID degradation and better high-temperature performance than legacy PERC cells. - **Bifacial design boosting energy yield** - The double-sided construction captures light reflected from the ground surface, a practical advantage on bright roofs, carports, and ground-mount installations - a realistic gain of a few extra percent depending on ground albedo. - **Long product and power warranty (25/30 years)** - A 25-year product warranty combined with a 30-year linear power warranty simplifies long-term investment planning and compares favorably to many competing series that offer a standard 25-year power warranty with a lower guaranteed end-of-life output. - **Current-generation technology platform** - Launched in 2024, the series is built on the current N-type TOPCon cell generation rather than the aging PERC technology, resulting in a better power temperature coefficient and smaller output loss on hot days. - **Power range suited to space-constrained roofs** - A power range of 435 to 455 Wp in a 54-cell format helps maximize energy yield on limited roof area, which matters for projects with constrained installation space. ## Cons - **Not a BNEF Tier 1 manufacturer** - According to the BNEF Tier 1 Solar Module Manufacturers list (Q2 2026, 42 manufacturers including Jinko Solar, LONGi, Trina Solar, JA Solar, Tongwei), LEDVANCE is not included, which may limit project bankability for bank financing compared to Tier-1 brands such as IBC Solar. - **Short track record as a PV module manufacturer** - LEDVANCE was founded in 2016 as a lighting-focused OSRAM spin-off (OSRAM/SYLVANIA brands) and has been owned by China's MLS Group since 2018; its PV segment (Ledvance Renewables) is a comparatively new business line, lacking the multi-year manufacturing track record typical of dedicated PV brands. ## About this series The LEDVANCE M435~455N54LB-SF-F7 series are modules engineered to maximize energy yield on limited roof surfaces - where every square meter counts. The application of **N-type cells in TOPCon technology** helps maintain high operational efficiency even under challenging temperature conditions and variable sunlight, translating to a more stable annual yield. This is also thanks to the **bifacial design**, enabling the module to utilize light reflected from the ground - a practical advantage on light-colored roofs, carports, and ground-mounted systems. A key feature of the series is also its **extended warranty coverage**, facilitating long-term investment planning, and **high operational durability** due to high-quality materials and meticulously engineered lamination. These panels are an excellent choice for installers and investors seeking premium-grade modules for homes, businesses, and commercial projects, where predictable returns and longevity are prioritized over compromises. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 217.7 W/m² matches the \*\*TOPCon 400-450W\*\* median - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 24.5 kg, this panel is 2.5 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - 100% bifaciality enables rear-side power generation, boosting yield by 5-15% on reflective surfaces ## Questions ### What does the 435~455 power range in the LEDVANCE M435~455N54LB-SF-F7 name mean, and how many watts does this panel actually produce? The M435~455 designation indicates the factory sorting bin range: each module is measured during a Flash Test and classified to a specific bin between 435 and 455 Wp. The top-tier variant reaches 455 Wp, and the Flash Test report is included with delivery so the installer can verify the exact power of each panel received. For system design purposes, safely assume 450-455 Wp for the premium bin. ### What warranty does the LEDVANCE M435~455N54LB-SF-F7 series carry, and what does it cover? The series comes with a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. Over that 30-year period, the manufacturer guarantees the module retains a specified minimum output — typically above 87% of nominal power. This is among the longest warranty coverages available in the premium module market and is a key factor when calculating long-term ROI. ### Does the TOPCon technology in the LEDVANCE M435~455N54LB-SF-F7 deliver a real advantage over PERC panels? Yes. N-type TOPCon cells deliver higher cell efficiency, a lower temperature coefficient, and slower annual degradation compared to PERC technology. In practice this translates to a few percentage points more annual energy yield, especially on hot days when module temperature rises. The M435~455N54LB-SF-F7 series generates more power from the same roof footprint without increasing the panel count. ### When does the bifacial design of the LEDVANCE M435~455N54LB-SF-F7 actually boost energy production? Bifacial modules capture light reflected off the ground through the rear cell surface, increasing yield by roughly 5-15% under favorable conditions. The gain is greatest on highly reflective surfaces such as white roofing membranes, gravel ballast, concrete, or carport decks. On dark roof tiles the benefit is minimal. For ground-mount arrays and carport installations, the bifacial construction provides a clearly measurable energy advantage. ### How do the LEDVANCE M435~455N54LB-SF-F7 panels perform in winter and under overcast conditions in Central European climates? N-type TOPCon cells feature a lower temperature coefficient and superior low-irradiance performance compared to standard PERC modules. On overcast winter days or at the low sun angles common in Central Europe, these panels lose less efficiency than older-technology modules. This is a meaningful advantage in markets like Poland, where seasonal irradiance variability between summer and winter is significant. ### Is LEDVANCE a reliable solar panel manufacturer, and is the M435~455N54LB-SF-F7 series suitable for residential or commercial installations? LEDVANCE is a German-headquartered brand primarily known for lighting that has expanded into photovoltaics. The manufacturer is not currently listed on Bloomberg's Tier 1 module ranking — a factor worth considering when evaluating investment insurance and financing options. That said, the M435~455N54LB-SF-F7 series, with its N-type TOPCon cell technology, bifacial construction, and 25-year product warranty, meets the performance and durability standards expected of premium modules for both residential and commercial projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/asset-13237389-m435-455n54lb-bf-f7-395bb9f136be.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.5 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, cooler, +2.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.5 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, cooler, +2.5 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.5 pp | | [LEDVANCE M440N54LB-SF-F7](https://comparepv.com/panel/ledvance-m440n54lb-sf-f7) | 440 W | +0.2 pp | | [LEDVANCE M445N54LB-SF-F7](https://comparepv.com/panel/ledvance-m445n54lb-sf-f7) | 445 W | +10 W, +0.5 pp | | [LEDVANCE M450N54LB-SF-F7](https://comparepv.com/panel/ledvance-m450n54lb-sf-f7) | 450 W | +15 W, +0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, cooler, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/ledvance-m435n54lb-sf-f7 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.
