The 108HC M10 NTYP SL Bifacial series is built around N-Type TOPCon cells, which offer lower degradation and better high-temperature performance, making them especially well suited for installations operated intensively over many years. The half-cut cell technology reduces power losses related to shading and internal resistance, resulting in more stable energy output under variable irradiance conditions. The dual-sided, glass-glass bifacial construction also captures light reflected from the ground surface, boosting total energy yield without increasing the installation footprint - a solution particularly attractive for mounting on light-colored roofs, facades, or ground-mount farms with elevated albedo. The reinforced frame and 3.2 mm tempered front glass provide high mechanical resistance to hail, wind, and snow loads, which matters in more demanding operating conditions. These panels are a solid choice for investors seeking a lower LCOE over the full lifecycle of an installation, suitable for both commercial projects and larger prosumer arrays where the ratio of energy yield to roof area and long-term product reliability are key considerations.

What owners get
N-type TOPCon cells with low degradation

The N-type TOPCon technology combined with half-cut cell design reduces LID/LeTID degradation and shading losses, resulting in higher and more stable energy yield over the module's lifetime compared to older PERC cells.

Bifacial glass-glass construction

The double-glass bifacial design (3.2 mm front glass) captures light reflected from the ground, increasing total energy yield without expanding the installation footprint - particularly beneficial on light-colored roofs or ground-mount farms with elevated albedo.

Efficiency up to 22.79% - above peer average

The series' top-end efficiency (22.79%) exceeds comparable tier-1 bifacial modules such as Jinko Tiger Neo 54HL4R-BDB (22.27%), Q.TRON BLACK (22.3%), and Astronergy ASTRO N7s (22.3%), at the same 445 Wp max power.

Low power temperature coefficient

A Pmax temperature coefficient of -0.30%/°C ensures better power retention in high temperatures than typical PERC modules (usually -0.35 to -0.40%/°C), which matters for installations in high-irradiance climates.

Bankable tier-1 manufacturer since 2010

Heliene has operated since 2010, holds tier-1 bankable status, and runs manufacturing facilities in North America (Canada/USA), easing project financing and eligibility for US domestic content programs.

Trade-offs
Price premium for North American manufacturing

Heliene modules manufactured in Canada/USA typically carry a higher unit price than comparable tier-1 Asian-made modules (Jinko, Astronergy), which may reduce cost competitiveness on projects that don't qualify for domestic content bonuses.

Common questions

6 answered
What is the difference between the Heliene 108HC M10 NTYP SL Bifacial series and standard monofacial panels?
The key difference is the glass-glass construction with dual-sided light capture, allowing the module to generate energy from reflected light off the ground as well. This typically results in an additional energy yield of a few to over ten percent without increasing the installation footprint, especially noticeable on light-colored roofs, facades, or ground-mount farms with high albedo.
What warranty comes with the Heliene 108HC M10 NTYP SL Bifacial panels?
The manufacturer provides a 25-year product warranty and a 25-year power performance warranty. This is one of the longer coverage periods available on the market, made possible by the N-type TOPCon cells, which show lower annual degradation compared to conventional P-type PERC cells.
How much power does the Heliene 108HC M10 NTYP SL Bifacial panel produce and what installations is it suited for?
The module reaches a maximum power output of 445 Wp. With its high unit power and bifacial technology, it works well for both commercial installations and larger prosumer systems where the ratio of energy yield to available roof or ground area matters most.
Does N-type TOPCon technology in Heliene panels make a real difference for a system owner?
Yes. N-type TOPCon cells degrade more slowly than traditional P-type cells and handle high operating temperatures better, resulting in more stable energy production during summer months. Over the long term, this means higher cumulative energy yield across a 25-30 year system lifespan, and therefore a lower LCOE.
Do Heliene 108HC M10 NTYP SL Bifacial panels require special mounting to take advantage of their bifacial design?
To effectively use the rear side of the module, panels should be mounted on structures that leave clearance underneath, such as elevated ground-mount racking or flat roofs with an appropriate tilt angle. Mounting directly flush on a sloped roof without clearance limits the bifacial gain, though the panel will still perform normally on its front side.
Can the tempered glass and reinforced frame of the Heliene 108HC M10 NTYP SL Bifacial withstand harsh weather conditions?
Yes, the module features 3.2 mm tempered front glass and a reinforced frame, providing strong mechanical resistance to hail, high winds, and snow load. This is a significant advantage for installations in regions with variable climate conditions, where glass breakage is often a common cause of warranty claims.
