The L/lab FORTIS N5 series from Luxen Solar was engineered to answer the growing demands of installations exposed to extreme weather - heavy wind loads, snow accumulation, and hail. The modules feature bifacial N-type TOPCon half-cut cells with SMBB LECO technology, delivering stable energy generation even under low irradiance and diffuse light conditions. A defining trait of the series is its ultra-high mechanical load resistance - the module withstands up to 8000 Pa on the front side and 4000 Pa on the rear, making it well suited for harsh climates, steeply pitched roofs carrying heavy snow, and ground-mount installations exposed to strong winds. The bifacial double-glass construction captures additional energy yield from reflected light on the rear side, boosting total output without expanding the installation footprint. The panels also stand out for their excellent anti-PID performance and low LID, ensuring stable output over the long service life of the system. These characteristics allow investors and installers using the FORTIS N5 series to reduce BoS and LCOE costs, making it an attractive choice for large-scale solar farms as well as demanding commercial and industrial installations where reliability and long-term durability are essential.

What owners get
Top-tier efficiency in its class

Efficiency up to 22.84% places the FORTIS N5 series among the leading 590 Wp bifacial N-type modules - on par with the Horay Solar HS 182-144 Ocean (22.8%) and Talesun TM7G72M (22.8%), just behind the segment leader AE Solar HORIZON (22.86%).

Exceptional mechanical load rating

A front load rating of up to 8000 Pa and rear load of up to 4000 Pa significantly exceeds the typical industry standard (around 5400 Pa / 2400 Pa), making the series a strong choice for ground-mount installations and roofs exposed to high wind, snow, or hail.

30-year power warranty from a Tier-1 maker

The manufacturer guarantees over 87.4% of rated power after 30 years, and Luxen Solar has held continuous BloombergNEF Tier-1 bankable status since 2022, reducing counterparty risk for long-term commercial and utility-scale PV projects.

Bifacial TOPCon with SMBB LECO technology

Half-cut N-type bifacial cells with SMBB LECO and a dual-glass construction deliver low LID degradation and strong PID resistance, while the additional rear-side energy gain increases total output without expanding the installation footprint.

Trade-offs
High module weight (dual glass)

The dual-glass bifacial construction results in a module weight of around 27.5 kg, which increases mounting structure requirements and installation costs on large rooftop arrays compared to lighter glass-backsheet modules.

Limited track record on the market

The FORTIS N5 series launched in 2024, so it lacks multi-year field performance data compared to competing lines that have been on the market longer - a factor worth weighing for bank-financed projects.

Notes from the database
  • Efficiency of 22.8% matches the N-type 550-600W median

Common questions

6 answered
How much extra energy can I gain from the bifacial L/lab FORTIS N5 panels?
The dual-glass bifacial design of the FORTIS N5 modules captures light reflected off the ground on the rear side of the panel. Depending on surface albedo (grass, gravel, white roofing), the additional energy gain can range from a few percent up to double digits compared to standard mono-facial panels, without increasing the installation footprint.
Will FORTIS N5 panels hold up in regions with heavy snowfall and strong wind?
Yes, this is the series' core strength. The module withstands front-side loads up to 8000 Pa and rear-side loads up to 4000 Pa, well above typical panels on the market. This makes FORTIS N5 well suited for steep-slope roofs with heavy snow accumulation and ground-mount installations exposed to strong wind.
What is SMBB LECO technology and does it actually improve panel performance?
SMBB (Super Multi Busbar) increases the number of thin busbars on the cell, reducing resistive losses and improving current collection, while LECO (Light and Electric Current induced Regeneration) is a regeneration process for N-type TOPCon cells that lowers LID and LeTID degradation. In practice, this results in higher and more stable energy output over the panel's lifetime.
What warranty comes with the Luxen L/lab FORTIS N5 panels?
The manufacturer offers a 20-year product warranty and a 30-year linear power output warranty. This means the panel should retain a guaranteed percentage of its initial power output after 30 years, making FORTIS N5 a strong choice for long-term investments, including utility-scale farms and commercial installations.
Do FORTIS N5 panels perform well under low sunlight or diffuse light conditions?
Yes, thanks to bifacial N-type TOPCon half-cut cells, FORTIS N5 modules maintain stable energy production even in overcast weather or during morning and evening diffuse light. The half-cut cell design also reduces losses from partial shading, improving actual energy yield under less than optimal sunlight.
How does FORTIS N5 compare to standard mono-facial PERC panels in terms of installation cost-effectiveness?
With a high 590 Wp power rating, bifacial technology, and ultra-high mechanical strength, FORTIS N5 helps reduce BoS costs (wiring, mounting structures, labor) per installed watt and lowers LCOE over the system's lifetime. This is a significant advantage over older PERC panels, especially in large-scale farm and industrial installations.
