The low temperature coefficient of -0.29%/°C limits output losses on hot days. - **30-year power warranty at 87.4% end-of-term output** - The manufacturer guarantees at least 87.4% of nominal power after 30 years of operation, a stronger term than the standard 25-year linear warranties common among competitors in this power class (440-445 Wp). - **Glass-glass construction** - The dual 2 mm glass layers improve resistance to moisture, mechanical loads, and PID degradation compared to conventional glass-backsheet modules, supporting more predictable long-term energy yield for investors. - **Bifacial gain on bright surfaces** - The active rear side captures reflected light, which is meaningful for ground-mount installs, carports, membrane roofs, or bright rooftops - unlike monofacial designs such as the SunEvo SE6-46SC. ## Cons - **No Tier-1 (BNEF) status** - LEDVANCE does not appear on the BloombergNEF Tier 1 manufacturer list, unlike competitor Q-Cells (Q.TRON BLACK). Founded in 2016, the company is primarily known as a lighting brand (former Osram licensee), which may matter for project bankability assessments by financing institutions. - **Limited market track record for this series** - The series launched in 2024, and LEDVANCE has a comparatively short history as a PV module manufacturer relative to established players like Q-Cells, limiting the availability of long-term field degradation data. ## About this series The LEDVANCE M440~445N48RB-SF-F7 series are bifacial modules based on N-type TOPCon technology, designed for real-world performance, not just catalog parameters. Thanks to their active rear side, they better utilize reflected light from the ground, which is key on light-colored roofs, ground-mounted systems, carports, and membrane installations. This solution is ideal for installations where stable performance across various conditions-including higher temperatures-is essential, with a focus on **low degradation over time**. The glass-glass construction enhances resistance to moisture and mechanical stress, which appeals to investors seeking long-term operation and reduced warranty claims. Additionally, the module is designed to minimize the PID effect, supporting predictable energy production. This series is suitable for premium home installations and commercial PV systems, where reliable quality, the attractive silver frame, and guaranteed yields over years are important. ## Notable figures - Efficiency of 22.0% matches the \*\*TOPCon 400-450W\*\* median - Power density of 220.2 W/m² matches the \*\*TOPCon 400-450W\*\* median - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 400-450W\*\* median - 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 - In the top 45% for efficiency among all TOPCon panels ## Questions ### What warranty does the LEDVANCE M440~445N48RB-SF-F7 series come with? The M440~445N48RB-SF-F7 series includes a 25-year product warranty and a 30-year linear power output warranty. This is among the longest warranty packages available in the residential and commercial PV market, meaning the manufacturer guarantees a defined minimum power output for three decades. For investors financing installations through loans or leases, this long-term coverage directly supports bankability and project return calculations. ### What is TOPCon technology and why does the LEDVANCE M440~445N48RB-SF-F7 series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that adds a thin tunnel oxide passivation layer to suppress carrier recombination at the rear contact. In practice, this delivers higher cell efficiency compared to standard PERC and a lower temperature coefficient, meaning the module loses less power on hot days. The M440~445N48RB-SF-F7 series uses TOPCon to achieve lower annual degradation and more predictable energy yields over its full service life. ### How much extra energy does the bifacial design of the LEDVANCE M440~445N48RB-SF-F7 actually produce? The M440~445N48RB-SF-F7 bifacial modules capture light from both the front and rear surfaces thanks to a glass-glass build without an opaque backsheet. Real-world bifacial gain typically ranges from 5 to 15 percent above rated power, depending on ground albedo. Maximum gains are seen on white membrane roofs, light-colored gravel, snow, and ground-mount systems with sufficient module clearance. On dark asphalt shingles, the rear-side contribution will be negligible. ### Are the LEDVANCE M440~445N48RB-SF-F7 panels suitable for carport or ground-mount installations? Yes, the M440~445N48RB-SF-F7 series is well suited for carports and ground-mount systems. The glass-glass construction improves mechanical strength and moisture resistance, which matters in open-air exposure conditions. Bifacial cells harvest reflected irradiance from the ground surface or paving below, boosting yield. The silver frame (SF) integrates naturally into industrial and ground-mount racking aesthetics, and up to 445 Wp per module helps optimize string sizing and BoS costs. ### Is LEDVANCE a reliable solar panel manufacturer - what should buyers know about the brand? LEDVANCE is headquartered in Germany and historically tied to the OSRAM brand, now operating as an independent manufacturer of lighting and photovoltaic products. The company is not currently listed as a Tier-1 module manufacturer by Bloomberg NEF, meaning it lacks the multi-year high-volume shipment track record of top-tier PV producers. Buyers should verify warranty service availability in their country and confirm that the local distributor offers post-sale support before committing to a large installation. ### Can the LEDVANCE M440~445N48RB-SF-F7 series be installed on a sloped residential roof? Yes, M440~445N48RB-SF-F7 modules can be mounted on standard pitched roofs using conventional racking systems compatible with the 66-cell format (approximately 1722×1134 mm). The silver aluminum frame (SF) works with most commercially available rail-and-clamp systems. Keep in mind that on a pitched roof the bifacial gain will be limited due to minimal rear-side irradiance reflected from roofing material. The module will perform primarily as a single-sided unit, while still benefiting fully from TOPCon N-type efficiency and low degradation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/asset-13237380-m440-445n48rb-sf-f7-6b107c100b72.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, lighter, +2.5 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, lighter, +2.5 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, lighter, +2.3 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, lighter, +2.3 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, cooler, +2.3 pp | | [LEDVANCE M435N54LB-SF-F7](https://comparepv.com/panel/ledvance-m435n54lb-sf-f7) | 435 W | Hotter, -0.2 pp | | [LEDVANCE M445N54LB-SF-F7](https://comparepv.com/panel/ledvance-m445n54lb-sf-f7) | 445 W | Hotter, +0.2 pp | | [LEDVANCE M450N54LB-SF-F7](https://comparepv.com/panel/ledvance-m450n54lb-sf-f7) | 450 W | +10 W, hotter, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.7 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +65 W, cooler, +2.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, lighter, +2.5 pp | --- Source: https://comparepv.com/panel/ledvance-m440n48rb-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 and alternatives filtered by how closely they match these dimensions.
