The use of N-type technology results in naturally low light-induced degradation (LID), allowing the panels to maintain high efficiency throughout their entire service life rather than just in the first years after installation. The **half-cut** cell design reduces cell-to-module losses and improves resilience to partial shading, meaningfully boosting energy production in installations with less-than-ideal exposure. The dual-sided, **bifacial construction** captures light reflected off the ground, increasing overall yield without requiring additional installed area - a solution particularly attractive for solar farms and industrial rooftops with light-colored surfaces. A reinforced frame paired with thick, 3.2mm tempered glass delivers strong **mechanical load resistance**, making these panels well suited to regions with heavy snow and wind loads. A low temperature coefficient of power further limits performance drops on hot days. This series is a natural choice for commercial and industrial investors seeking low LCOE and long-term production stability. ## Notable figures - At 23.0% efficiency, this panel is 0.6pp above typical \*\*N-type 550-600W\*\* modules (median: 22.4%) - Power density of 230.2 W/m² packs 5.7 W/m² more into the same footprint vs \*\*N-type 550-600W\*\* median (224.5 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 13% for efficiency among all N-type panels ## Questions ### What is the maximum power output of the Heliene 144HC M10 NTYP SL Bifacial panels? Modules in this series reach a maximum power of up to 595 Wp, placing them among high-output panels for commercial and industrial applications. This high power output results from 144 N-type TOPCon cells in a half-cut configuration, which reduces electrical losses and improves conversion efficiency compared to older P-type technologies. ### How does N-type TOPCon technology differ from classic PERC panels? N-type TOPCon cells have a significantly lower light-induced degradation (LID) rate than PERC cells based on P-type silicon. This means the Heliene 144HC M10 NTYP SL Bifacial panels lose less power in their first year of operation and maintain higher efficiency throughout their lifespan, resulting in higher energy yield over the long term. ### Are the Heliene 144HC M10 NTYP SL Bifacial bifacial panels worth it on an industrial roof? Yes, especially if the roof has a light, reflective surface (such as a PVC membrane or gravel). The double-sided design captures light reflected off the ground surface, boosting total yield by several to over ten percent without increasing the installation footprint. These panels also perform well on solar farms with elevated mounting structures. ### What warranty comes with the Heliene 144HC M10 NTYP SL Bifacial panels? The manufacturer offers a 15-year product warranty covering manufacturing defects, along with a 25-year linear power output warranty. This means mechanical quality is protected for a decade and a half, while power degradation over time follows a guaranteed schedule for a quarter century, a standard benchmark for Tier 1 panels. ### Can the Heliene 144HC M10 NTYP SL Bifacial panels handle heavy snow load regions? Yes, the modules feature a reinforced frame and 3.2 mm tempered glass, providing high mechanical resistance to snow and wind loads. The half-cut cell design further increases resistance to microcracking under high stress, making these panels a solid choice for installations in climates with harsh winters. ### Is Heliene a Tier 1 manufacturer and where is the company based? Yes, Heliene is classified as a Tier 1 manufacturer, confirming its financial stability and years of experience in solar module production. The company is headquartered in Canada and is recognized for producing panels with high-quality components, which matters when selecting a supplier for large commercial and industrial projects where long-term reliability is essential. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HSPE_144HC_M10_NTYP_SL_Bifacial_Rev02-092025-766c0102ca71.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, +2.0 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Lighter, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, +1.8 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Lighter, +1.6 pp, +5 yr warranty | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, +1.6 pp, +5 yr warranty | | [Heliene 144HC-520 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-520-m10-sl-bifacial) | 520 W | -75 W, hotter, -2.9 pp | | [Heliene 144HC-525 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-525-m10-sl-bifacial) | 525 W | -70 W, hotter, -2.7 pp | | [Heliene 144HC-530 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-530-m10-sl-bifacial) | 530 W | -65 W, hotter, -2.5 pp | | [Heliene 144HC-535 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-535-m10-sl-bifacial) | 535 W | -60 W, hotter, -2.3 pp | | [Heliene 144HC-540 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-540-m10-sl-bifacial) | 540 W | -55 W, hotter, -2.1 pp | | [Heliene 144HC-545 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-545-m10-sl-bifacial) | 545 W | -50 W, hotter, -1.9 pp | | [Heliene 144HC-550 M10 SL BIFACIAL](https://comparepv.com/panel/heliene-144hc-550-m10-sl-bifacial) | 550 W | -45 W, hotter, -1.7 pp | | [Heliene 144HC-555 M10 NTYP SL Bifacial](https://comparepv.com/panel/heliene-144hc-555-m10-ntyp-sl-bifacial) | 555 W | -40 W, -1.5 pp | | [Heliene 144HC-560 M10 NTYP SL Bifacial](https://comparepv.com/panel/heliene-144hc-560-m10-ntyp-sl-bifacial) | 560 W | -35 W, -1.3 pp | | [Heliene 144HC-565 M10 NTYP SL Bifacial](https://comparepv.com/panel/heliene-144hc-565-m10-ntyp-sl-bifacial) | 565 W | -30 W, -1.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, +2.2 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-144hc-595-m10-ntyp-sl 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.
