The temperature coefficient for Pmax is -0.30%/°C, translating to measurably lower summer losses compared to PERC modules (~-0.35%/°C) — a significant advantage in high-irradiance locations or on rooftops with poor ventilation. - **Up to 22.53% Efficiency – Top of Its Peer Group** - A peak efficiency of 22.53% places the series on par with the Seraphim Nebula (22.53%) and above the KDM Kingdom Solar KDM SERIES (22.5%). The only direct competitor in this power class offering higher efficiency is the Luxor ECO LINE N-TYPE TOPCon Non-Reflect (22.86%), although Luxor does not offer a full-black variant. - **Tier 1 North American Manufacturer** - Heliene (founded 2010, Sault Ste. Marie, Canada; manufacturing lines in Canada and Minnesota, USA) holds Tier 1 bankable status and was named a PVEL Top Performer 2022 by the independent laboratory PV Evolution Labs. North American production eliminates exposure to anti-dumping tariffs on Chinese imports and simplifies project qualification for the IRA (Inflation Reduction Act) investment tax credit in the US market. - **Half-Cut 108HC Cell Architecture – Superior Shading Tolerance** - Splitting each cell in half reduces internal resistance and limits losses under partial shading conditions — each half-row operates independently of the other. Combined with three junction boxes (the standard configuration for 108HC modules), the series is less susceptible to localized shading than full-cell modules, directly improving annual energy yield on complex rooftop layouts. - **25/25-Year Warranty and Premium Full-Black Aesthetics** - A 25-year product warranty paired with a 25-year linear power warranty (to 90% of rated power after 25 years per the datasheet) is the premium-segment benchmark, confirming the manufacturer's financial and service reliability. The All Black variant (black frame, black backsheet, black cells) addresses the growing residential installation market, where aesthetics rank alongside performance as a purchase criterion. ## Cons - **Peak Efficiency 0.33 pp Below Luxor** - In the same power class (up to 440 Wp), the Luxor ECO LINE N-TYPE TOPCon Non-Reflect achieves 22.86% efficiency versus 22.53% for Heliene — a 0.33 percentage-point gap that translates to approximately 1.4% less energy generated annually for an identical module footprint. For installations with constrained roof area, this difference may be a decisive argument in favor of Luxor. - **No Bifacial Configuration Available** - The series is monofacial (SL – Single Layer backsheet), which precludes any albedo gain; bifacial TOPCon modules typically harvest 5–15% additional energy under favorable conditions (light-colored ground surface, ground-mount installation). This is a deliberate design choice — the full-black construction requires an opaque backsheet — however, installers executing ground-mount or utility-scale projects should evaluate bifacial alternatives. ## About this series The Heliene 108HC M10 NTYP SL All Black series consists of modules designed for installations where both high energy production and a consistent, black appearance on the roof are important. The use of **monocrystalline N-type (NTYP) cells** helps to minimize typical power losses over time, while the **half-cut (108 cells) design** improves performance under partial shading and reduces the risk of overheating, resulting in more stable performance in real-world conditions. The **anti-reflective glass** also deserves attention, as it better "collects" light during the day, and the mechanically refined frame is designed to withstand wind and snow loads - important in more challenging locations and for larger roof areas. The module also has **high PID resistance**, which increases reliability in environments with high humidity and temperature. This is a good choice for modern residential and small commercial installations, especially where a full black aesthetic must be combined with premium technology. ## Notable figures - Efficiency of 22.5% is 0.5pp above the \*\*TOPCon 400-450W\*\* median (22.0%) - 225.3 W/m² power density - 5.1 W/m² more than \*\*TOPCon 400-450W\*\* median (220.2 W/m²), more power per roof area - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - In the top 28% for efficiency among all TOPCon panels ## Questions ### Is the Heliene 108HC M10 NTYP SL All Black series suitable for a sloped residential roof? Yes, the All Black series from Heliene is designed with residential sloped-roof installations in mind. The 440 W modules feature compact dimensions that simplify transport and on-roof handling, while the 108 half-cut cell layout improves performance under partial shading from chimneys or dormers. The black frame and black backsheet blend seamlessly with dark roof coverings such as ceramic or asphalt shingles. ### What is TOPCon technology and why does Heliene use it in this series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type monocrystalline cell technology that minimizes carrier recombination losses at the cell contacts. Compared to standard PERC cells, TOPCon modules deliver higher conversion efficiency and lower long-term degradation. In practice, this means more stable energy output throughout the entire 25-year power warranty period. ### How does the 108HC M10 NTYP SL All Black perform under partial shading? The half-cut design splits each cell into two halves, reducing the operating current per cell and limiting power losses and hot-spot risk when part of the module is shaded. If a row of cells is shaded by an antenna or chimney, the unshaded half of the module continues to operate with significantly lower losses than a full-cell panel would experience under the same conditions. ### What warranties come with the Heliene 108HC M10 NTYP SL All Black panels? Heliene provides a 25-year product warranty and a 25-year power output warranty for this series. The power warranty guarantees that after 25 years of operation the module will retain a defined percentage of its 440 W nameplate power. Heliene is a Bloomberg NEF Tier 1 manufacturer, which confirms the financial stability needed to back long-term warranty commitments. ### Do Heliene NTYP SL All Black modules perform well in winter and on overcast days? TOPCon technology delivers a favorable temperature coefficient of approximately -0.30%/°C, meaning the panels lose less power at low temperatures than older PERC cells. Additionally, the anti-reflective coated glass captures more diffuse irradiance on cloudy days. As a result, the 108HC M10 NTYP SL All Black series produces energy efficiently year-round, not only in peak sunshine. ### Is the Heliene 108HC M10 NTYP SL All Black a bifacial panel? No, the 108HC M10 NTYP SL All Black is a monofacial module, meaning it generates power from the front side only. The SL (single-glass) construction uses a black backsheet instead of a rear glass pane, achieving a uniform all-black aesthetic at a lower weight than dual-glass bifacial alternatives. This makes it the right choice for installations where appearance and straightforward mounting are the top priorities. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hspe-108hc-m10-ntyp-sl-all-blk-rev-00-1-e537d3a2ccf5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, +2.0 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, +2.0 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, +1.8 pp, +5 yr warranty | | [Heliene 108HC-380 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-380-m10-sl-all-black-monofacial) | 380 W | -60 W, hotter, -3.0 pp | | [Heliene 108HC-385 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-385-m10-sl-all-black-monofacial) | 385 W | -55 W, hotter, -2.8 pp | | [Heliene 108HC-390 M10 SL S1 All Black](https://comparepv.com/panel/heliene-108hc-390-m10-sl-s1-all-black) | 390 W | -50 W, hotter, -2.5 pp | | [Heliene 108HC-395 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-395-m10-sl-all-black-monofacial) | 395 W | -45 W, hotter, -2.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, +2.3 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +60 W, +2.0 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-108hc-m10-ntyp-sl-all-black-module-440w-class Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
