Light for its output, no clear weak spot
The LEDVANCE M385~405P54LM-BB-F3 series are monofacial panels in full black version, designed for installations where both energy yield and a uniform, elegant roof appearance are important. The modules are based on PERC technology and monocrystalline cells, enabling efficient light capture even under less-than-ideal conditions, while maintaining stable performance during hot days. The manufacturer focuses on PID effect limitation through premium materials and controlled production processes, genuinely reducing the risk of performance drops over time. In practice, this translates to smoother operation and predictable results, especially for residential and commercial installations with high aesthetic standards. The module construction prioritizes durability, and low annual degradation supports long-term investment profitability. This is an excellent choice for clients seeking full black without compromise regarding reliability and manufacturing quality.
Ranking
Signals from the data
Residential and commercial.
Top 9% of the PERC 350-400 W segment, against a median of 55.8. Ranked 4,519th in the whole database.
The monofacial full black version with black frame and black backsheet delivers a uniform roof appearance, a strong selling point for residential installations with high aesthetic requirements.
Half-cut monocrystalline PERC cells (108-cell layout) reduce power loss under partial shading and lower hotspot risk compared to full-size cell modules.
The top-end efficiency of 20.74% at 405 Wp matches direct peer comparables - EGing PV STAR Series and VSUN VSUN405-108BMH-DG - which offer the identical 20.74% at the same peak power.
The manufacturer states reduced PID (Potential Induced Degradation) effect through higher-grade materials and controlled manufacturing, lowering the risk of accelerated power loss in humid, hot operating conditions.
The stated low annual power degradation, combined with the 25-year power warranty, results in more predictable energy yield over the installation's full lifecycle.
The series was discontinued in the same year it was released (2023). Warranty service, replacement parts availability, and module-matching for future system expansion may be limited going forward.
The module relies on older PERC technology, while the market has clearly shifted toward N-type TOPCon and HJT cells since 2024-2026, which offer lower LID/LeTID degradation and better high-temperature performance.
LEDVANCE is not listed as a Tier-1 bankable manufacturer per BloombergNEF, which can complicate financing for commercial projects where banks require Tier-1 status as a lending condition.
12 years of product warranty and 25 years of linear power warranty reflects an older market standard - leading manufacturers among the peer comparables (e.g. Goldi Solar, VSUN) increasingly offer 25-30 years product warranty and up to 30 years power warranty.
- Efficiency of 20.2% is 0.8pp above the PERC 0-400W median (19.4%)
- Power density of 202.3 W/m² packs 8.1 W/m² more into the same footprint vs PERC 0-400W median (194.2 W/m²)
- Temperature coefficient of -0.35%/°C matches the PERC 0-400W median
- Ranked #12013 out of 14129 panels for efficiency in the database
