Efficiency leader, weak in heat
The Luxor Solar ECO LINE N-TYPE HJT GLASS-GLASS BIFACIAL series is an advanced solution based on heterojunction technology (HJT), which sets new standards of efficiency even in difficult lighting conditions. By combining N-type cells with a glass-glass construction, these modules effectively eliminate the problem of voltage- and light-induced degradation, offering users unprecedented durability and yield stability for decades. A key differentiator is bifacial activity, allowing for the generation of additional energy from radiation reflected off the ground. Combined with an exceptionally low temperature coefficient, this ensures that the system works much more efficiently on hot days than standard competitor modules. The glass-glass construction provides the highest mechanical and chemical resistance, making these panels an ideal choice for installations in demanding environments or on roofs with limited space. By choosing this series, investors receive maximum yield per unit area and a guarantee of longevity that traditional panels with backsheet foil do not provide. This is a premium-class product dedicated to modern single-family homes and professional photovoltaic farms, where the lowest levelized cost of energy and failure-free operation for years are of key importance.
Ranking
Signals from the data
Residential, utility-scale and hot-climate.
Hot climates.
Top 1% of the HJT 450-500 W segment, against a median of 22.77%. Ranked 433rd in the whole database.
Top 4% of the HJT 450-500 W segment, against a median of 227.7. Ranked 853rd in the whole database.
Bottom 22% of the HJT 450-500 W segment, against a median of -0.240.
Maximum efficiency of 24.12% outperforms all three key peers: Runergy HY-DH156N8 (23.1%), Resun RS9K-M (22.79%), and Canadian Solar HiHero+ Bifacial HJT (23.9%) at the same 645 Wp peak power.
N-type heterojunction cells virtually eliminate LID/PID degradation and feature a low power temperature coefficient, resulting in higher energy yield on hot days compared to standard PERC modules.
Two-sided activity allows for additional energy gain from albedo reflected off the ground, while the glass-glass encapsulation (instead of backsheet) provides higher mechanical and chemical resistance, especially valuable in harsh environments.
The manufacturer offers 30 years of both product and power warranty - exceeding the typical market standard of 12-25 years on product, lowering long-term investment risk.
The 455-645 Wp range across 8 variants allows the series to fit both single-family homes and professional PV farms without changing cell technology.
Luxor Solar (Germany, founded in 2007) does not appear on the current BNEF Tier 1 list, which may complicate obtaining bank financing for large utility-scale projects despite the brand's European origin.
The glass-glass design, while increasing durability, is heavier than backsheet panels, potentially requiring reinforced mounting structures, especially on roofs with limited load capacity.
- At 23.8% efficiency, this panel is 1.0pp above typical HJT 450-500W modules (median: 22.8%)
- Power density of 234.8 W/m² packs 7.1 W/m² more into the same footprint vs HJT 450-500W median (227.7 W/m²)
- -0.26%/°C temperature coefficient - 0.02pp worse than HJT 450-500W median (-0.24%/°C), expect higher hot weather losses
- 92% bifaciality enables rear-side power generation, boosting yield by 5-14% on reflective surfaces
- In the top 3% for efficiency among all HJT panels

Datasheet charts
Measured curves published by Luxor Solar in this model's datasheet. A chart carrying a wattage was measured on that variant alone - only the ones that describe 465 Wp appear here. The rest cover the whole series.
Simulations
Degradation from this panel's own datasheet figures. No inverter, soiling or shading losses.
Model: bifaciality × albedo × 0.6 view factor. A first-order estimate, not a yield simulation.
