Light for its output, short guarantee
The Heliene 156HC M10 NTYP SL Bifacial Module series is designed for maximum energy yield in situations where every percentage counts. The use of N-type cells results in more stable performance over time and reduced sensitivity to typical start-up losses, allowing the installation to "pay for itself" more quickly. A key advantage is the bifacial design - the panel can also utilize reflected light from the ground, which is particularly beneficial for PV farms, ground-mounted installations, and roofs with light-colored or reflective surfaces.
In practice, this series addresses the problem of reduced production in challenging conditions: it supports the low temperature coefficient characteristic of N-type architecture and the half-cut design, which improves tolerance to partial shading and reduces internal losses. Furthermore, the modules have a reinforced frame and tempered glass with an anti-reflective coating, making them suitable for locations exposed to wind, snow, and hail. This is the choice for investors, EPCs, and designers seeking higher productivity and long-term reliability.

N-type TOPCon cells deliver annual linear degradation of ≤0.4%/year, guaranteeing ≥88% of nameplate power after 25 years. First-generation PERC modules degrade at 0.45–0.55%/year — a gap that compounds to tens of MWh per MW of installed capacity over a 20-year project life. The low temperature coefficient (typically –0.29 to –0.30%/°C for N-type architecture) further reduces summer generation losses.
The double-sided structure captures reflected irradiance from ground surfaces. In ground-mounted systems with light gravel or white aggregate (albedo 0.20–0.35), bifacial gain translates to 8–15% additional energy output. The 156-cell half-cut layout simultaneously reduces internal resistive losses and improves partial-shading tolerance.
Heliene holds Tier-1 (bankable) status from Bloomberg NEF, streamlining project financing with institutional lenders and infrastructure funds. Manufacturing in Canada and the USA (Sault Ste. Marie, ON) qualifies modules for IRA Domestic Content status, enabling an additional 10% investment tax credit adder on US projects — a material LCOE advantage for North American EPC and IPP stakeholders.
The manufacturer guarantees ≥88% of nameplate power after 25 years with a maximum annual degradation of 0.4%. As a North American Tier-1 producer with an established regional service network, Heliene services this warranty locally — a relevant risk differentiator for Canadian and US EPC projects compared to offshore manufacturers.
The module uses 3.2 mm fully tempered front glass with an anti-reflective coating and a reinforced aluminum frame rated for the snow and wind load conditions characteristic of Canadian climate zones and northern US states. The series launched in 2024 and remains in active production.
The series peaks at 22.73% efficiency, while direct peer comparables score higher: Longi Hi-MO X10 Explorer at 23.5% and Sunpro Power TOPCon 210R at 23.51%. The 0.77–0.78 percentage-point gap equals roughly 3.3% less power from the same roof or land area. On space-constrained rooftop installations, this may require one additional module per ~30 m² to reach the same peak power output.
The workmanship warranty covers 15 years, whereas leading Tier-1 manufacturers in the same power class — including Longi and JA Solar — standardly offer 25-year product warranties. The 10-year shortfall is material in utility-scale projects with 20–30 year financing horizons, where lenders may require residual warranty coverage analysis as part of bankability due diligence.
- At 22.4% efficiency, this panel is on par with typical TOPCon 600-650W modules
- 223.7 W/m² power density is 4.0 W/m² below TOPCon 600-650W median (227.7 W/m²) - requires larger installation area
- Temperature coefficient of -0.30%/°C matches the TOPCon 600-650W median
- At 31.0 kg, this panel is 1.7 kg lighter than TOPCon 600-650W median (32.7 kg) - easier handling during installation
- Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface
