Conventional PERC modules typically degrade at 0.45–0.55%/yr. N-type cells also eliminate the LID (Light-Induced Degradation) effect that can strip 1–3% from P-type module output within the first few months of operation. - **Up to 22.64% efficiency — top of segment** - The top-power variant (585 Wp) reaches 22.64% module efficiency, matching direct peer comparables: Hanersun Hitouch 5N (22.65%), Risen RSM144-9 (22.60%), and Q-SUN Qrystal N8 (22.65%). The Heliene series sits firmly among the leading 144-cell M10 TOPCon modules released in 2024–2025. - **Bifacial design with transparent backsheet** - The bifacial transparent-backsheet construction (as opposed to heavier glass-glass) enables rear-side energy harvest — typical bifacial gain ranges from 5–15% depending on ground albedo and tilt angle. The design keeps module weight lower than glass-glass alternatives, simplifying logistics and roof mounting on industrial facilities. - **Kiwa PVEL Top Performer 2024 (10th edition)** - Heliene earned Top Performer status in the 10th edition of the Kiwa PVEL PV Module Reliability Scorecard (published June 2024), covering thermal cycling, damp heat, mechanical stress, PID, and hail resistance testing. This independent certification is a key bankability signal for utility-scale and commercial projects seeking project-finance approval. - **Tier-1 bankable, North American manufacturing** - Heliene appears on bankable-manufacturer lists (Solar Insure Tier-1 List 2025) and operates its own U.S. production lines in Mountain Iron, MN (800 MW) and Rogers, MN (500 MW), totaling 1.3 GW of annual capacity as of May 2025. For projects requiring bank financing or IRA domestic content bonus credits, this is a meaningful advantage over manufacturers without North American production. ## Cons - **15-year product warranty — below premium standard** - The series carries a 15-year workmanship warranty, whereas leading premium-segment competitors — JA Solar, LONGi, Jinko Solar — routinely offer 25-year product warranties. The shorter coverage can be a limiting factor in project-finance structures that require a minimum 20–25-year warranty term and represents a clear disadvantage relative to direct peers in the same power and efficiency class. - **Limited availability outside North America** - Heliene's distribution network and after-sales service are concentrated in the U.S. and Canada; no confirmed European distribution hubs or local warehousing have been identified. For installers and developers in Poland and the EU, this may translate into longer lead times, higher logistics costs, and more complex warranty claim processes compared with Tier-1 manufacturers that maintain European distribution centers (e.g., Risen, Hanersun). ## About this series The Heliene 144HC M10 NTYP SL series is a bifacial module designed for maximum energy yield in real-world conditions, including situations where reflected light from the ground and stable production over time are crucial. The use of **N-type cells in TOPCon technology** reduces light-induced degradation, helping to maintain high efficiency over the module's lifespan. The **half-cut (144 cells per module)** design minimizes internal losses and improves performance under partial shading, making the module suitable for roofs with complex geometries and commercial installations with infrastructure elements. Another advantage is **bifaciality with a transparent backsheet**, which allows for energy harvesting from the rear side without complicating the design. The module also features a **reinforced frame and tempered glass** - a practical solution for areas exposed to hail, snow, and strong winds. This makes it a good choice for PV farms, industrial rooftops, and projects where low energy costs and predictable production are priorities. ## Notable figures - Efficiency of 22.1% matches the \*\*TOPCon 550-600W\*\* median - At 220.6 W/m², this panel generates 3.8 W/m² less per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - At 29.2 kg, this panel is 2.0 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg) - easier handling during installation - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### What warranty comes with the Heliene 144HC M10 NTYP SL Bifacial module? The 144HC M10 NTYP SL series includes a 15-year product warranty and a 25-year linear power guarantee. Heliene guarantees at least 99% of rated power output in year one and a maximum annual degradation of 0.4%, ensuring no less than 88% of initial power after 25 years. As a Tier 1 manufacturer, Heliene's financial standing adds further credibility to these long-term commitments. ### What does bifacial mean for the Heliene 144HC M10 NTYP SL in practice, and how much extra energy can it generate? The module features a transparent backsheet that allows the rear side of the TOPCon cells to harvest light reflected from the ground. In ground-mounted systems with high-albedo surfaces such as gravel or light-colored concrete, rear-side energy gain typically ranges from 5% to 25%, depending on tilt angle and surface reflectivity. On rooftops the gain is smaller but still measurable and requires no additional hardware. ### How does the TOPCon cell technology in the Heliene 144HC M10 NTYP SL differ from standard PERC modules? N-type TOPCon cells exhibit significantly lower light-induced degradation (LID) compared to conventional P-type PERC cells, meaning less power loss during the first weeks of operation. A more favorable temperature coefficient also improves output on hot days. As a result, annual degradation is capped at 0.4%, whereas PERC modules typically show 0.55-0.70% per year, leading to a measurable LCOE advantage over a 25-year project lifetime. ### Is the Heliene 144HC M10 NTYP SL suitable for large commercial rooftops and utility-scale PV farms? Yes, this series is designed primarily for commercial and utility-scale applications. A peak power output of 585 Wp per module reduces the total module count, lowering Balance of System (BoS) costs through fewer mounting structures and less cabling. The reinforced aluminum frame and 3.2 mm fully tempered front glass provide resistance to hail, snow loads, and high wind pressure — critical requirements for long-term large-scale projects. ### How does the Heliene 144HC M10 NTYP SL handle partial shading from chimneys or roof obstructions? The half-cut cell design splits the module into two independent electrical sections of 72 half-cells each. When one section is shaded, the other continues operating at full capacity, substantially reducing overall energy losses. This makes the module well suited for complex rooftop installations where ventilation pipes, skylights, or antennas cast periodic shadows across the module surface. ### How much power will the Heliene 144HC M10 NTYP SL retain after 25 years compared to older technologies? Heliene's linear power guarantee ensures a minimum of 88% of rated power after 25 years, with 99% retained in year one and no more than 0.4% annual degradation. Standard PERC modules typically degrade at 0.55-0.70% per year, leaving roughly 83-86% of initial power at year 25. For large-scale projects, this difference translates into meaningful additional energy production and a lower LCOE over the system's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hspe-144hc-m10-ntyp-sl-bifacial-rev-00-79ad406bf620.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Lighter, +2.7 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Lighter, +2.5 pp, +5 yr warranty | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Lighter, +2.3 pp, +5 yr warranty | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Lighter, +2.3 pp, +5 yr warranty | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Lighter, +2.3 pp, +5 yr warranty | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, +2.2 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Lighter, +2.1 pp, +5 yr warranty | | [Heliene 144HC-520 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-520-m10-sl-bifacial) | 520 W | -50 W, hotter, -2.0 pp | | [Heliene 144HC-525 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-525-m10-sl-bifacial) | 525 W | -45 W, hotter, -1.8 pp | | [Heliene 144HC-530 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-530-m10-sl-bifacial) | 530 W | -40 W, hotter, -1.6 pp | | [Heliene 144HC-535 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-535-m10-sl-bifacial) | 535 W | -35 W, hotter, -1.4 pp | | [Heliene 144HC-540 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-540-m10-sl-bifacial) | 540 W | -30 W, hotter, -1.2 pp | | [Heliene 144HC-545 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-545-m10-sl-bifacial) | 545 W | -25 W, hotter, -1.0 pp | | [Heliene 144HC-550 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-550-m10-sl-bifacial) | 550 W | -20 W, hotter, -0.8 pp | | [Heliene 144HC-555 M10 NTYP SL Bifacial](https://comparepv.com/panel/heliene-144hc-555-m10-ntyp-sl-bifacial) | 555 W | -15 W, -0.6 pp | | [Heliene 144HC-560 M10 NTYP SL Bifacial](https://comparepv.com/panel/heliene-144hc-560-m10-ntyp-sl-bifacial) | 560 W | -10 W, -0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, +3.1 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-144hc-570-m10-ntyp-sl-bifacial Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
