They utilize **N-type wafers in TOPCon technology**, offering superior performance in challenging operating conditions and more stable production compared to many standard P-type solutions. Another distinguishing feature is the **glass-glass construction**, which enhances resistance to moisture, mechanical stress, and accelerated aging - making these panels ideal for roofs subjected to intense use and variable weather conditions. This series is for investors seeking to mitigate performance degradation risk and rely on predictable yields - applicable in both residential installations and commercial projects. A practical advantage during installation is the use of **original Stäubli MC4 EVO 2 connectors** and thoroughly optimized solutions for the reliable operation of the entire string. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 217.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - At -0.29%/°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 - #7297 for efficiency, #2220 for temperature performance out of 14129 panels ## Questions ### How does TOPCon cell technology in the LEDVANCE M435~440N48RB-BB-F7 series compare to older PERC cells? TOPCon N-type cells feature an additional tunnel oxide passivation layer that reduces charge-carrier recombination losses. In practice this means higher conversion efficiency, a lower temperature coefficient, and slower long-term degradation compared to standard P-type PERC modules. The M435~440N48RB-BB-F7 series reaches up to 440 Wp thanks to this technology and holds its output better at elevated rooftop temperatures. ### What warranty does the LEDVANCE M435~440N48RB-BB-F7 series come with and what does it cover? LEDVANCE provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty guaranteeing the module stays above a defined power threshold throughout that period. A 30-year performance warranty is among the longer commitments available in the market and helps investors model a more predictable return on investment. ### What practical advantage does the glass-glass build of the LEDVANCE M435~440N48RB-BB-F7 panels offer over a conventional backsheet module? Replacing the PVF/PET backsheet with a rear glass pane significantly reduces moisture ingress, improves resistance to mechanical stress and fire, and slows UV-related aging. For rooftop installations exposed to heavy rainfall, strong winds, or wide temperature swings, this translates into a measurably longer service life and lower risk of delamination or corrosion over the module's lifetime. ### How much additional energy yield can I expect from the bifacial design of the LEDVANCE M435~440N48RB-BB-F7 panels on a pitched roof? Bifacial modules harvest reflected irradiance on the rear surface. On a pitched roof with a light-colored tile or white membrane, the real-world bifacial gain typically ranges from 5 to 15 percent above the front-side rated power. The actual uplift depends on the surface albedo and tilt angle, with ground-mounted systems or roofs with high-reflectance finishes yielding the greatest benefit. ### Are the Stäubli MC4 EVO 2 connectors on the LEDVANCE M435~440N48RB-BB-F7 compatible with standard PV wiring and other MC4 connectors? Stäubli MC4 EVO 2 connectors follow the widely adopted MC4 standard and are mechanically compatible with most MC4-type cables and connectors from other manufacturers. However, mixing connector brands may require certified adapters to maintain the IP68 waterproof rating and comply with IEC 62852 requirements. Using mismatched connectors without adapters can void the warranty and create arc-fault risks. ### Is LEDVANCE a reliable solar panel manufacturer and is the M435~440N48RB-BB-F7 series a safe long-term investment? LEDVANCE is a German-headquartered brand best known for lighting that has expanded into photovoltaic systems. It is not currently ranked as a Bloomberg NEF Tier 1 PV module manufacturer, meaning its production scale is smaller than the industry's leading players. Before purchasing, it is advisable to confirm the availability of local warranty service in your country and obtain the full warranty terms in writing to assess long-term support risk. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/asset-13236099-m440n48rb-bb-f7-en-d8dc86636bbb.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, lighter, +2.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, lighter, +2.5 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +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 | Hotter, +0.2 pp | | [LEDVANCE M445N54LB-SF-F7](https://comparepv.com/panel/ledvance-m445n54lb-sf-f7) | 445 W | +10 W, hotter, +0.5 pp | | [LEDVANCE M450N54LB-SF-F7](https://comparepv.com/panel/ledvance-m450n54lb-sf-f7) | 450 W | +15 W, hotter, +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, lighter, +3.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.9 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +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, lighter, +2.7 pp | --- Source: https://comparepv.com/panel/ledvance-m435n48rb-bb-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 and alternatives filtered by how closely they match these dimensions.
