PERC also carries a higher LID degradation coefficient than N-type technologies (TOPCon/HJT) now common in this power segment. - **Monofacial only, no bifacial variant** - The series does not offer a bifacial option, excluding additional energy yield from rear-side albedo available in competing double-sided modules, such as those used in ground-mount installations or on light-colored roofs. ## About this series The 132HC M10 SL Monofacial series is built for installations where both aesthetics and mechanical durability matter. The modules are based on **half-cut monocrystalline PERC cells**, which reduce power losses associated with shading and cell-to-module (CTM) transitions. The distinctive **frame - glass - backsheet design** gives the panels a uniform, elegant look, making them well suited for roofs and facades that are visible from the outside, such as residential and commercial installations with higher aesthetic requirements. The **reinforced aluminum frame** increases resistance to snow and wind loads, making this series a solid choice for harsher climates and locations exposed to extreme weather events. The panels feature **premium solar glass with an anti-reflective coating**, which reduces light reflection and enables higher energy yield throughout the day, even at unfavorable angles of sunlight incidence. As a result, the 132HC M10 SL Monofacial series combines structural reliability with high energy efficiency, offering a versatile solution for individual investors and installation companies alike who are looking for a proven, aesthetically refined next-generation monofacial panel. ## Notable figures - At 20.2% efficiency, this panel is 0.6pp below the \*\*PERC 450-500W\*\* median of 20.8% - At 202.1 W/m², this panel generates 6.4 W/m² less per unit area than \*\*PERC 450-500W\*\* median (208.5 W/m²) - Temperature coefficient of -0.34%/°C matches the \*\*PERC 450-500W\*\* median - At 27.0 kg, this panel is 2.5 kg heavier than the \*\*PERC 450-500W\*\* median (24.5 kg) - more demanding for installation crews - #11956 for efficiency, #8778 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Heliene 132HC M10 SL Monofacial panels? The 132HC M10 SL Monofacial series reaches a maximum power output of up to 500 Wp. This is achieved through monocrystalline PERC half-cut cells, which reduce power losses from partial shading and lower internal module resistance. It's a strong result for a monofacial panel using a conventional frame-glass-backsheet layout. ### Are Heliene 132HC M10 SL panels suitable for roofs exposed to public view? Yes, this is one of the series' main advantages. The uniform, elegant appearance resulting from the frame-glass-backsheet layout makes these panels well suited for residential roofs and commercial facades where aesthetics matter, such as street-facing single-family homes or corporate buildings with representative architecture. ### What warranty comes with the Heliene 132HC M10 SL Monofacial panels? Heliene provides a 15-year product warranty and a 25-year power performance warranty. Heliene is a tier-1 manufacturer headquartered in Canada, which adds credibility for long-term after-sales support and spare parts availability across North America and Europe. ### Can the reinforced frame on Heliene 132HC M10 SL panels handle heavy snow loads? Yes, the series features reinforced aluminum frames engineered for increased resistance to snow and wind loads. This makes the panels a good fit for demanding climates, such as mountain regions or large roof sections prone to snow drift accumulation. ### How does the monofacial 132HC M10 SL panel differ from bifacial modules? The 132HC M10 SL is a monofacial panel, generating energy only from its front side, unlike bifacial modules that also capture light reflected off the ground. Thanks to its conventional backsheet construction, it is lighter and less expensive than a bifacial module, while the anti-reflective solar glass coating helps offset part of the yield gap. ### Does the anti-reflective glass coating on Heliene 132HC M10 SL panels actually boost energy production? Yes, the premium solar glass with anti-reflective coating reduces light reflection off the panel surface, increasing the amount of sunlight reaching the cells. This is especially beneficial during morning and afternoon hours when the sun's angle of incidence is less favorable, resulting in higher total energy yield over the day and year. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HSPE_132HC_M10_SL_Monofacial_Rev05-ddce162b24f7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +4.8 pp, +5 yr warranty | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +4.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +4.5 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +4.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +4.3 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, lighter, +4.3 pp | | [Heliene 132HC-485 M10 SL](https://comparepv.com/panel/heliene-132hc-485-m10-sl) | 485 W | Very close match | | [Heliene 132HC-490 M10 SL](https://comparepv.com/panel/heliene-132hc-490-m10-sl) | 490 W | +10 W, +0.4 pp | | [Heliene 132HC-495 M10 SL](https://comparepv.com/panel/heliene-132hc-495-m10-sl) | 495 W | +15 W, +0.7 pp | | [Heliene 132HC-500 M10 SL](https://comparepv.com/panel/heliene-132hc-500-m10-sl) | 500 W | +20 W, +0.9 pp | | [Heliene 132HC-510 M10 NTYP SL](https://comparepv.com/panel/heliene-132hc-510-m10-ntyp-sl) | 510 W | +30 W, cooler, +1.3 pp | | [Heliene 132HC-515 M10 NTYP SL](https://comparepv.com/panel/heliene-132hc-515-m10-ntyp-sl) | 515 W | +35 W, cooler, +1.5 pp | | [Heliene 132HC-520 M10 NTYP SL](https://comparepv.com/panel/heliene-132hc-520-m10-ntyp-sl) | 520 W | +40 W, cooler, +1.7 pp | | [Heliene 132HC-525 M10 NTYP SL](https://comparepv.com/panel/heliene-132hc-525-m10-ntyp-sl) | 525 W | +45 W, cooler, +1.9 pp | | [Heliene 132HC-530 M10 NTYP SL](https://comparepv.com/panel/heliene-132hc-530-m10-ntyp-sl) | 530 W | +50 W, cooler, +2.1 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +110 W, +3.6 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-132hc-480-m10-sl Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
