N-type HJT technology also delivers lower LID/LeTID degradation than conventional PERC cells. - **Bifacial design with glass-glass build** - The bifacial construction captures additional rear-side energy reflected from the ground (light roofing, gravel, membrane) without adding more modules. The glass-glass encapsulation improves moisture and mechanical load resistance (up to 5400 Pa) and enhances fire safety class compared to glass-backsheet modules. - **30-year power warranty at 90.3%** - The manufacturer guarantees at least 90.3% of rated power after 30 years, alongside a 25-year product warranty. This degradation profile beats the typical 25-year linear warranty (usually around 84-87% remaining power) offered by many PERC/TOPCon peer manufacturers. - **Low temperature coefficient** - A Pmax temperature coefficient of -0.24%/°C is better than the typical -0.35% to -0.40%/°C seen on PERC modules, translating into smaller power losses during summer heat and higher real-world yield in hot climates. - **Component quality and aesthetics** - Modules feature original Stäubli MC4 EVO 2 connectors and an anodized black aluminum frame, easing servicing (connector compatibility) and improving aesthetics for residential roof installations. ## Cons - **No Tier-1 status per BNEF** - LEDVANCE does not appear on BloombergNEF's Tier-1 list (Q2 2026), unlike Risen Energy from the peer comparables. This can limit bankability for projects requiring bank or lease financing, where lenders often mandate Tier-1 modules. - **Limited manufacturing track record in PV** - LEDVANCE, founded in 2016, is primarily a lighting manufacturer, with its PV segment a relatively new business line launched alongside this series in 2023. A shorter PV track record means less field reliability data than manufacturers with a decade-plus of dedicated solar production. ## About this series The LEDVANCE M440-460H48RB-BF series are dual-sided high-performance photovoltaic modules featuring **HJT** technology, designed for optimal energy yield even under non-ideal roof or ground conditions. The rear side gain effectively utilizes reflected light from the surface (e.g., light-colored roof, gravel, membrane), significantly boosting energy production without installing additional modules. The **glass-glass** construction enhances resistance to moisture and mechanical stress while improving fire safety - a critical feature for installations exposed to challenging microclimates and heavy use. Thanks to HJT technology, these modules boast a **low degradation rate** over time, offering superior energy predictability compared to many standard panels. The manufacturer also highlights a **limited PID effect** due to quality control, reducing the risk of power loss in demanding systems. This makes them an excellent choice for residential and commercial installations, especially where aesthetics, durability, and reliable performance over years are essential. ## Notable figures - Efficiency of 22.8% matches the \*\*HJT 450-500W\*\* median - At 227.7 W/m² power density, roof space requirements are typical for \*\*HJT 450-500W\*\* panels - Temperature coefficient of -0.24%/°C matches the \*\*HJT 450-500W\*\* median - Ranked #3073 out of 14005 panels for efficiency in the database ## Questions ### What is HJT technology in the LEDVANCE M440-460H48RB-BF panels and is it worth the premium? HJT (Heterojunction Technology) stacks a crystalline silicon wafer between two thin amorphous silicon layers, enabling higher cell efficiency and a very low temperature coefficient. For LEDVANCE M440-460H48RB-BF owners, this means less power loss on hot summer days compared to standard PERC modules. The technology also delivers a lower annual degradation rate, keeping energy output more predictable well into year 20–25 of the system's life. ### How does the bifacial design of the LEDVANCE M440-460H48RB-BF actually work, and when does it pay off? The M440-460H48RB-BF modules harvest light from both the front and rear surfaces, generating extra energy from ground-reflected irradiance. The bifacial gain is greatest over light-colored surfaces such as white roofing membranes, gravel, or snow, and can add 5–15% above the rated 460 Wp. On dark substrates or with near-zero module clearance the rear-side contribution is negligible. ### What warranty does the LEDVANCE M440-460H48RB-BF series come with? LEDVANCE provides a 25-year product warranty covering mechanical and electrical integrity of the module, plus a 30-year linear power output warranty. Thanks to the inherently low degradation of HJT cells, modules are expected to maintain predictable output throughout the entire warranty period. Keep your proof of purchase and installation documentation, as warranty claims are handled through authorized LEDVANCE partners. ### Does the glass-glass construction of the LEDVANCE M440-460H48RB-BF matter in real-world rooftop conditions? Yes. Dual-glass lamination replaces the conventional polymer backsheet, dramatically reducing moisture ingress into the cell encapsulant — a key advantage in climates with high humidity cycles and freeze-thaw cycles. The glass-glass build also improves resistance to snow and wind loads, and the glass rear sheet raises the fire safety class of the installation compared to foil-back modules. ### What is the maximum power output of the LEDVANCE M440-460H48RB-BF and what annual energy yield can I expect? Peak power under STC conditions reaches 460 Wp. At typical European mid-latitude irradiance of 950–1,050 kWh/m² per year, a single module will produce roughly 420–480 kWh annually, depending on tilt, azimuth, and shading. The bifacial gain and low HJT degradation can push that figure a few percent higher than an equivalent PERC module over the same period. ### Are the LEDVANCE M440-460H48RB-BF panels suitable for both residential and commercial installations? Yes. The all-black frame makes the M440-460H48RB-BF a clean aesthetic fit for residential rooftops where appearance matters. At the same time, the 30-year power warranty, glass-glass construction, and limited PID effect make these modules a solid choice for commercial and industrial systems operating in demanding microclimates. LEDVANCE, headquartered in Germany, distributes the panels through a network of authorized installers across Europe. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/asset-13237473-m440-460h48rb-bf-f9-en-69a328976631.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, hotter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, hotter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, hotter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, hotter, +1.7 pp | | [LEDVANCE M435N54LB-SF-F7](https://comparepv.com/panel/ledvance-m435n54lb-sf-f7) | 435 W | -20 W, hotter, -1.0 pp | | [LEDVANCE M440N54LB-SF-F7](https://comparepv.com/panel/ledvance-m440n54lb-sf-f7) | 440 W | -15 W, hotter, -0.8 pp | | [LEDVANCE M445N54LB-SF-F7](https://comparepv.com/panel/ledvance-m445n54lb-sf-f7) | 445 W | Hotter, heavier, -0.5 pp | | [LEDVANCE M450N54LB-SF-F7](https://comparepv.com/panel/ledvance-m450n54lb-sf-f7) | 450 W | Hotter, heavier, -0.2 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, +2.2 pp | --- Source: https://comparepv.com/panel/ledvance-m440-460h48rb-bf-455w 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.
