## Pros

- **N-type TOPCon with low degradation** - 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.
- **Bifacial design — additional albedo yield** - 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.
- **BNEF Tier-1 bankable, North American manufacturing** - 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.
- **25-year linear power warranty** - 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.
- **Robust mechanical construction** - 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.


## Cons

- **Efficiency below segment leaders** - 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.
- **15-year product warranty (below premium standard)** - 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.


## About this series

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.

- 31.0 kg weight - 1.7 kg lighter than \*\*TOPCon 600-650W\*\* median (32.7 kg), reducing installation effort
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof


## Questions


### What warranty does the Heliene 156HC M10 NTYP SL Bifacial series come with?

Heliene provides a 15-year product warranty covering material and workmanship defects. The linear power warranty runs for 25 years, with a maximum annual degradation of approximately 0.4% and a guaranteed minimum output of 86–88% of nominal power after 25 years. These terms are consistent with Tier 1 N-type module standards, as TOPCon cells inherently degrade more slowly than conventional P-type PERC cells.


### What real-world advantage does TOPCon N-type technology offer in the Heliene 156HC M10 NTYP SL, and is it worth the premium?

TOPCon N-type cells deliver a lower temperature coefficient (approx. -0.30%/°C) than standard P-type PERC, meaning less power loss on hot days. They also exhibit lower LID (Light-Induced Degradation), so the module loses minimal power in its first weeks of operation. For ground-mount systems and utility farms where long-term energy yield drives LCOE, the difference is measurable and typically justifies the higher upfront cost.


### How much extra energy does the bifacial design of the Heliene 156HC M10 NTYP SL actually produce?

Real-world bifacial gain depends on ground albedo and mounting height, but typically ranges from 5% to 15% additional annual energy compared to a monofacial module of the same front-side power. Best results come from ground-mount systems with high-albedo surfaces (gravel, sand, snow) or rooftops with a white TPO membrane. On dark bitumen roofs in urban settings, the gain is more modest, around 3–5%.


### Is the Heliene 156HC M10 NTYP SL Bifacial a good fit for a large utility-scale solar farm?

Yes, this series is designed for the utility and large commercial segment. With up to 635 Wp per module, fewer panels and fewer string connections are needed, directly reducing BoS costs. The reinforced frame and anti-reflective tempered glass meet snow and wind load standards required across most European and North American sites. Bifacial output improves further when modules are mounted on single-axis trackers or elevated at least 0.5 m above the ground.


### How does the Heliene 156HC M10 NTYP SL Bifacial handle partial shading?

The module uses a half-cut cell layout with 156 cells split into independent sub-strings. When one string is partially shaded by an antenna, chimney, or roof edge, only that section is affected and the rest of the module continues producing at full capacity. Combined with TOPCon N-type cells that perform well at low irradiance, the half-cut design results in higher energy yield on overcast days and in locations with intermittent shading.


### Is Heliene a reliable manufacturer, and will the 156HC M10 NTYP SL warranty still be honored in 10 years?

Heliene is a Canadian PV manufacturer rated Tier 1 by Bloomberg NEF, which confirms its documented financial capacity to honor warranty claims. The company operates manufacturing facilities in both North America and Europe and has an established track record on utility-scale projects. Tier 1 status and long-term market presence provide a solid basis for assessing warranty risk across the full 25-year power guarantee period.
