The LEDVANCE M470~490N60LB-BF-F7 series are bifacial N-type modules utilizing TOPCon technology, designed to maximize energy yield under real-world operating conditions. Their dual-sided structure harvests light from both sides, particularly advantageous on light-colored roofs, membranes, gravel, and rooftop structures where every percentage point of additional energy production matters. A key feature is the 120 half-cut cells layout, which helps minimize losses and enhances performance under partial shading, commonly encountered in installations atop buildings with chimneys, window wells, or vents. The application of SMBB technology improves current conduction within the cells, leading to more stable performance. The glass-glass construction enhances resistance to moisture and mechanical stress, while refined quality control minimizes the risk of PID effects. This makes them an excellent choice for residential and commercial installations prioritizing durability, predictable energy output, and the aesthetic appeal of the black frame.

Signals from the data

5 positive · 3 caution
Best for

Residential, commercial and shaded-installations.

What owners get
N-type TOPCon + bifacial design

N-type TOPCon cells show lower LID/LeTID degradation and better high-temperature performance than legacy PERC, while the bifacial construction adds rear-side energy yield - particularly beneficial on bright roofs, membranes, or ground-mount installations.

120 half-cut cells with SMBB

Half-cut cell segmentation reduces resistive losses and improves performance under partial shading (chimneys, dormers, roof vents), while SMBB (multi-busbar) technology improves current conduction and boosts long-term output stability.

Glass-glass construction

Dual-glass design (2 mm) increases moisture resistance and lowers PID risk compared to standard glass-backsheet modules, improving mechanical durability at a module weight of 25.5 kg.

30-year linear power warranty

The manufacturer guarantees a minimum of 87.4% of nominal power after 30 years, backed by a 25-year product warranty - a level comparable to leading peer series (e.g. DAH Solar DHN-60X16/DG), well above the standard 25-year warranties typical of PERC-generation modules.

Black frame aesthetics

The black-frame (BF) variant, with a black-backsheet (BB) version also available, addresses residential-segment demand where roof installation appearance matters to individual homeowners.

Trade-offs
No BNEF Tier 1 status

LEDVANCE does not appear on the BloombergNEF Tier 1 list (Q1 2026 edition), which can make bank-financed commercial projects harder to underwrite compared to modules from established Tier 1 manufacturers.

Efficiency slightly below top peers

The maximum efficiency of 22.63% trails comparable series such as Renesola RS4-470~490NX-E1 and DAH Solar DHN-60X16/DG (both at 22.71%) at the same 490 Wp max power - a small but real gap for large-scale installations measured in the hundreds of kW.

Limited track record in the PV market

LEDVANCE (Germany, founded in 2016) is a comparatively young player in the commercial PV segment versus manufacturers with decade-plus module production histories, limiting the availability of long-term field degradation data.

About the M470~490N60LB-BF-F7 series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty comes with the LEDVANCE M470~490N60LB-BF-F7 panels?
The LEDVANCE M470~490N60LB-BF-F7 series comes with a 25-year product warranty covering manufacturing defects and a 30-year power output warranty guaranteeing at least 87.4% of rated power after three decades of operation. This is one of the longer warranty terms on the market and reflects the durability expected from the glass-glass construction used in these modules.
Are the bifacial LEDVANCE M490 panels worth it for a light-colored roof or ground-mount system?
Yes, the bifacial design of the M470~490N60LB-BF-F7 captures energy from both direct sunlight on the front and reflected light from the surface below. The biggest bonus - potentially several to over ten percent more annual yield - is achieved on ground-mount systems with light-colored gravel, white roofing membrane, or concrete. On dark substrates the bifacial gain is noticeably smaller.
How does TOPCon technology in the LEDVANCE M470~490N60LB-BF-F7 differ from standard PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell with an additional passivation layer. Compared to PERC, it delivers higher module efficiency - up to 22.63% for the 490 Wp variant - and a lower temperature coefficient of -0.29%/°C, meaning less power loss on hot days. N-type cells are also less susceptible to light-induced degradation (LID), supporting stable output throughout the entire warranty period.
How does the LEDVANCE M470~490N60LB-BF-F7 series handle partial shading from chimneys or dormers?
The 120 half-cut cell layout splits the module into two independent electrical sub-strings. This means partial shading - from a chimney, dormer, or vent - only reduces output in the shaded half, rather than knocking out the entire module. Combined with SMBB technology that improves current conductivity, this series handles uneven irradiance better than older full-cell modules.
What are the dimensions and weight of the LEDVANCE M490 module, and does it fit standard rooftop mounting systems?
The LEDVANCE M490 N60LB-BF-F7 measures 1909×1134×30 mm and weighs approximately 25.5 kg. The slightly higher weight compared to backsheet modules is due to the dual-glass construction. The module is compatible with standard aluminum rail systems and glass-glass clamps used by most installers. Before installation, verify that the roof structure can handle the static and snow loads.
Why does the LEDVANCE M470~490N60LB-BF-F7 series have a black frame, and does it affect performance?
The black frame is primarily an aesthetic choice - the modules blend well with dark roof tiles and standing-seam metal roofing, which is often a deciding factor for homeowners focused on curb appeal. It has no effect on electrical performance. The darker frame may absorb slightly more heat on sunny days, but this has a negligible impact on annual energy yield.
