The **half-cut cell technology** reduces power losses related to shading and internal resistance, resulting in more stable energy output under variable irradiance conditions. The dual-sided, **glass-glass bifacial construction** also captures light reflected from the ground surface, boosting total energy yield without increasing the installation footprint - a solution particularly attractive for mounting on light-colored roofs, facades, or ground-mount farms with elevated albedo. The reinforced frame and 3.2 mm tempered front glass provide high mechanical resistance to hail, wind, and snow loads, which matters in more demanding operating conditions. These panels are a solid choice for investors seeking a **lower LCOE** over the full lifecycle of an installation, suitable for both commercial projects and larger prosumer arrays where the ratio of energy yield to roof area and long-term product reliability are key considerations. ## Notable figures - 22.8% module efficiency - 0.9pp better than the \*\*N-type 400-450W\*\* median of 21.9% - 227.9 W/m² power density - 9.6 W/m² more than \*\*N-type 400-450W\*\* median (218.3 W/m²), more power per roof area - At -0.30%/°C, hot weather performance is typical for \*\*N-type 400-450W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - Ranked #3005 out of 14005 panels for efficiency in the database ## Questions ### What is the difference between the Heliene 108HC M10 NTYP SL Bifacial series and standard monofacial panels? The key difference is the glass-glass construction with dual-sided light capture, allowing the module to generate energy from reflected light off the ground as well. This typically results in an additional energy yield of a few to over ten percent without increasing the installation footprint, especially noticeable on light-colored roofs, facades, or ground-mount farms with high albedo. ### What warranty comes with the Heliene 108HC M10 NTYP SL Bifacial panels? The manufacturer provides a 25-year product warranty and a 25-year power performance warranty. This is one of the longer coverage periods available on the market, made possible by the N-type TOPCon cells, which show lower annual degradation compared to conventional P-type PERC cells. ### How much power does the Heliene 108HC M10 NTYP SL Bifacial panel produce and what installations is it suited for? The module reaches a maximum power output of 445 Wp. With its high unit power and bifacial technology, it works well for both commercial installations and larger prosumer systems where the ratio of energy yield to available roof or ground area matters most. ### Does N-type TOPCon technology in Heliene panels make a real difference for a system owner? Yes. N-type TOPCon cells degrade more slowly than traditional P-type cells and handle high operating temperatures better, resulting in more stable energy production during summer months. Over the long term, this means higher cumulative energy yield across a 25-30 year system lifespan, and therefore a lower LCOE. ### Do Heliene 108HC M10 NTYP SL Bifacial panels require special mounting to take advantage of their bifacial design? To effectively use the rear side of the module, panels should be mounted on structures that leave clearance underneath, such as elevated ground-mount racking or flat roofs with an appropriate tilt angle. Mounting directly flush on a sloped roof without clearance limits the bifacial gain, though the panel will still perform normally on its front side. ### Can the tempered glass and reinforced frame of the Heliene 108HC M10 NTYP SL Bifacial withstand harsh weather conditions? Yes, the module features 3.2 mm tempered front glass and a reinforced frame, providing strong mechanical resistance to hail, high winds, and snow load. This is a significant advantage for installations in regions with variable climate conditions, where glass breakage is often a common cause of warranty claims. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HSPE_108HC_M10_NTYP_SL_Bifacial_Rev00-1-be8cef2aeec0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, +1.7 pp, +5 yr warranty | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, +1.7 pp, +5 yr warranty | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, +1.5 pp, +5 yr warranty | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, +1.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | +50 W, cooler, +1.5 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, +1.5 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 | -65 W, hotter, -3.3 pp | | [Heliene 108HC-385 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-385-m10-sl-all-black-monofacial) | 385 W | -60 W, hotter, -3.1 pp | | [Heliene 108HC-390 M10 SL S1 All Black](https://comparepv.com/panel/heliene-108hc-390-m10-sl-s1-all-black) | 390 W | -55 W, hotter, -2.8 pp | | [Heliene 108HC-395 M10 SL All Black (Monofacial)](https://comparepv.com/panel/heliene-108hc-395-m10-sl-all-black-monofacial) | 395 W | -50 W, hotter, -2.6 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, cooler, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +55 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, +1.7 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-108hc-445-m10x-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.
