For insurers and PV project financiers, this significantly reduces counterparty risk, an advantage that is particularly material given a 25-year warranty horizon. - **M10 Half-Cut Cells with MBB Technology** - Splitting PERC cells in half (half-cut) reduces internal resistance and cell-to-module (CTM) losses, while multi-busbar (MBB) architecture improves light absorption and resistance to microcracks. As a result, the series achieves 390–410 Wp at 20–21% efficiency, matching peer-comparable Sunket SKT410~430M10-108D4 (21%) and outperforming the VDS-S144/FNH (20.4%). - **Full All-Black Aesthetics — Ideal for Dark Roofs** - A uniform black frame, backsheet, and cells eliminate the contrasting silver borders visible on standard modules. The solution is purpose-built for the premium residential microinstallation segment, where aesthetics drive purchasing decisions and the array must blend seamlessly into a dark roofing surface. - **25-Year Product and Power Output Warranty** - Heliene offers a full 25-year warranty covering both the product and power output performance (minimum ~86% of rated power after 25 years). This represents a premium-segment standard, consistent with peer-comparables such as Luxor and Sunket, and a meaningful advantage over manufacturers offering only 12–15 years of product warranty. - **High Mechanical Resistance — S1 Form Factor** - The reinforced S1-series frame is engineered to withstand higher wind and snow loads compared to the base SL variant. For installations on hard-to-access roof sections in the Polish climate — where snow loads can reach 5,400 Pa — this translates into a concrete operational advantage. ## Cons - **Discontinued Product Line** - The 108HC M10 SL S1 All Black series has been discontinued (year of introduction: 2023). This results in limited availability of replacement modules in the event of damage, a risk of color mismatch during any future system expansion, and potential difficulties in honoring warranty claims once distributor inventory stocks are exhausted. - **PERC Technology Being Displaced by N-Type TOPCon** - The direct peer-comparable Luxor Eco Line N-type TOPCon achieves 21.33% efficiency with lower degradation rates (approximately 1% in year one vs. ~2% for PERC; ~0.40%/year vs. ~0.45%/year for PERC). Over a 25-year horizon, this translates into measurably higher annual energy yield — without a price premium for an All-Black form factor. - **Elevated Thermal Losses from Black Backsheet** - A black backsheet absorbs more thermal radiation than a white one, generating approximately 2% in additional energy losses on sunny days. This effect partially offsets the series' stated 'excellent thermal stability' and is especially pronounced under Polish summer heat wave conditions. ## About this series The Heliene 108HC M10 SL S1 All Black panel series consists of technologically advanced modules that redefine standards for aesthetics and performance in the Polish micro-installation sector. By utilizing **Half-Cut cells** in the M10 format, these panels effectively minimize power losses resulting from internal resistance and offer higher resistance to localized shading. A key differentiator is their **elegant All Black finish**, which makes the installation almost invisible on dark roofing materials, making them the preferred choice for demanding homeowners. The module construction utilizes **multi-busbar technology (MBB)**, which not only increases light absorption but also improves the reliability of electrical connections, protecting the system against micro-cracks. This solution eliminates the problem of unsightly silver frames, while offering **optimized weight and mechanical strength**, which significantly accelerates installation work on hard-to-reach roof surfaces. Unlike mass-market competition, this series emphasizes excellent thermal stability, resulting in higher energy yields on hot days. This is a proposal for those seeking uncompromising quality, where modern technology meets the highest attention to every visual detail of the system. ## Notable figures - At 21.0% efficiency, this panel is on par with typical \*\*PERC 400-450W\*\* modules - Power density of 210.0 W/m² packs 3.8 W/m² more into the same footprint vs \*\*PERC 400-450W\*\* median (206.2 W/m²) - At -0.35%/°C, hot weather performance is typical for \*\*PERC 400-450W\*\* panels - #9758 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### Is the Heliene 108HC M10 SL S1 All Black series still available for purchase? The Heliene 108HC M10 SL S1 All Black series has been discontinued. Heliene currently offers successor lines such as the 108HC M10 NTYP SL All Black (415–440 W) featuring N-Type cell technology. If you are looking for a comparable All Black module with M10 monocrystalline cells, ask your distributor about next-generation Heliene products or compare offerings from other Tier 1 manufacturers. ### What warranty does Heliene provide on the 108HC M10 SL S1 All Black series? Heliene provides a 25-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. This means the manufacturer guarantees module power will remain above specified degradation thresholds for a full quarter century — one of the strongest warranty packages available in the residential PV segment. ### What is Half-Cut PERC technology and what does it mean for the Heliene 108HC M10 SL S1 series? PERC (Passivated Emitter and Rear Cell) raises conversion efficiency by reflecting unabsorbed photons back through the cell from a passivated rear surface. Half-cut means each PERC cell is laser-cut in half, which reduces internal resistance and power losses while significantly improving shade tolerance — for example, from a chimney or dormer. In practice, this results in higher annual energy yield compared to standard full-cell modules. ### How many cells does the Heliene 108HC M10 SL S1 All Black have and what is its rated power output? The module features 108 monocrystalline PERC half-cut cells in M10 format (182 mm cell size) with a peak power output of 410 Wp under Standard Test Conditions (STC). Multi-Busbar (MBB) interconnection technology increases light capture and improves tolerance to micro-cracks in the cells, contributing to longer system lifetime and sustained performance over the module's service life. ### Does the All Black finish affect the efficiency of the Heliene 108HC M10 SL S1 panel? The All Black finish — black frame and black backsheet instead of a standard white backsheet — has minimal impact on efficiency. The black frame may slightly raise operating temperature on very hot days; however, PERC half-cut cells have a low temperature coefficient that limits power losses under heat. The aesthetic benefit of a nearly invisible panel on a dark roof far outweighs this marginal thermal difference. ### Are the Heliene 108HC M10 SL S1 All Black panels suitable for a pitched roof with chimneys or dormers? Yes, the half-cut cell design makes these modules noticeably more resilient to partial shading than conventional full-cell panels. Shading one half of the module from a chimney or dormer causes significantly smaller power losses than with older full-cell designs. For persistent or extensive shading, pairing the modules with power optimizers or microinverters is still recommended to maximize energy yield. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hspe-108hc-m10-sl-s1-monofacial-blk-rev-02-5a286064a8a1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, cooler, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [Heliene 108HC-380 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-380-m10-sl-all-black-monofacial) | 380 W | -30 W, -1.5 pp | | [Heliene 108HC-385 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-385-m10-sl-all-black-monofacial) | 385 W | -25 W, -1.3 pp | | [Heliene 108HC-390 M10 SL S1 All Black](https://comparepv.com/panel/heliene-108hc-390-m10-sl-s1-all-black) | 390 W | -20 W, -1.0 pp | | [Heliene 108HC-395 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-395-m10-sl-all-black-monofacial) | 395 W | -15 W, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +80 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/heliene-108hc-410-m10-sl-s1-all-black Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
