The Luxor Solar ECO LINE N-TYPE (Black Frame) series is designed for maximum energy yield while maintaining high durability in everyday operating conditions. The use of N-type TOPCon solar cells ensures stable production even when the modules are subjected to higher temperatures, while also helping to minimize typical performance-reducing phenomena over time. In practice, this translates to a more predictable and reliable self-consumption balance and installation results.

A key feature is the glass-glass construction, which improves the mechanical and thermal resistance of the module, supports its long lifespan, and makes it easier to maintain its performance over time. The version with a black frame provides a consistent aesthetic, which is particularly desirable on residential and modern building roofs.

This solution is for investors who want to combine aesthetics with premium-class technology - from residential installations and commercial rooftops to projects where high reliability and minimizing indirect costs due to increased power from a single module are essential.

What owners get
N-type TOPCon cells

The N-type TOPCon technology offers a lower LID/LeTID degradation rate and a favorable temperature coefficient of -0.3%/°C, translating into more stable energy yield under high irradiance and elevated module operating temperatures compared to older PERC technology.

Glass-glass construction

The dual-glass laminate improves mechanical and thermal durability, reduces PID risk and micro-crack susceptibility, supporting retention of rated power output throughout the 25-year linear power warranty.

High unit power up to 575 Wp

Efficiency up to 22.51% and power up to 575 Wp reduce module count and BoS costs (racking, wiring, labor) per installed kW while keeping roof footprint compact.

Sleek black frame design

The Black Frame variant delivers a uniform, understated look, which is a strong selling point for residential rooftop installations and modern architecture where visual integration matters.

Established manufacturer since 2007

Luxor Solar is a German company operating in the PV market since 2007, with over 15 years of module supply track record - longer than many newer N-type brands in this segment.

Trade-offs
No BNEF Tier-1 bankable status

The manufacturer is not listed on BloombergNEF's Tier-1 bankable supplier list, unlike some competing brands in this power segment (555-575 Wp), which can complicate financing for commercial projects requiring bankable modules.

Monofacial-only option

The series lacks a bifacial variant, while the comparable Sunpro 210R TOPCon BIFACIAL achieves higher 23.35% efficiency at the same maximum power (575 Wp) thanks to additional rear-side energy gain.

About the ECO LINE N-TYPE (Black Frame) series

6 answered

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

What is the warranty on Luxor Solar ECO LINE N-TYPE (Black Frame) panels?
Luxor Solar provides a 15-year product warranty and a 25-year linear power warranty on the ECO LINE N-TYPE (Black Frame) series. This means the manufacturer guarantees a defined minimum output level for a quarter century. The warrantor is a German company headquartered in Stuttgart, which matters when filing warranty claims - there are no third-party intermediaries involved.
What is N-type TOPCon technology and why choose it over conventional PERC cells?
N-type TOPCon cells offer a lower power temperature coefficient (typically around -0.30%/°C) compared to standard PERC cells (around -0.35%/°C). In practice, this means smaller output losses during summer heat when modules run hot. N-type technology also exhibits lower LID (light-induced degradation), resulting in more stable long-term performance and better LCOE over the module's operational lifetime.
Are the Luxor ECO LINE N-TYPE (Black Frame) panels a good choice for a residential rooftop installation?
Yes, the black frame variant is designed primarily for residential and modern commercial rooftops. The uniform all-black aesthetics give the installation a clean, cohesive look. Modules rated up to 575 Wp mount on standard racking systems for pitched roofs, compatible with both tile and metal roofing. The black frame makes them especially popular where visual appearance is a priority.
How many Luxor ECO LINE N-TYPE 575 Wp panels do I need for a typical home system?
At 575 Wp per module, a 6 kWp system requires just 11 panels, while a 10 kWp system needs around 18 modules. The high per-panel wattage reduces the number of components on the roof, shortens installation time, and lowers BoS costs (wiring, racking, connectors). This is especially advantageous when roof space is limited or the roof has an irregular shape.
What are the benefits of the glass-glass construction in the ECO LINE N-TYPE series?
In a glass-glass module, the standard backsheet is replaced by a second pane of glass. This dramatically improves resistance to moisture ingress, UV exposure, and mechanical stress. For the ECO LINE N-TYPE, it means better protection against cell corrosion and micro-cracks caused by long-term thermal cycling. The result is lower annual degradation and greater confidence in meeting the 25-year power warranty commitments.
Is Luxor Solar a reliable manufacturer - are the ECO LINE N-TYPE panels certified?
Luxor Solar was founded in Stuttgart in 2007. While not listed on the BloombergNEF Tier 1 ranking, the company received the Top Brand PV Germany 2025 award from independent research firm EUPD Research. ECO LINE N-TYPE modules carry standard industry certifications (IEC 61215, IEC 61730). Luxor backs its 15-year product warranty directly as the German warrantor, with no third parties involved.
