At a typical cell operating temperature of 65°C (40°C above STC), a 710 Wp module loses approximately 10.4 W less than an equivalent TOPCon module — translating into meaningfully higher annual energy yield in high-irradiance locations. - **Efficiency 22.21–22.86% — top of the segment** - The series ranks among the best peer comparables in its class: Axitec AXIbiperfect GXQ TS, Phono Solar Draco, and Solarspace SS9-66HD achieve an identical maximum efficiency of 22.86%. The lower bound of 22.21% (690 Wp model) still surpasses the majority of G12 TOPCon modules available in a comparable power range. - **Glass-glass construction with bifacial HJT cells** - The dual-glass encapsulation eliminates the backsheet, which is susceptible to UV degradation and moisture ingress, extending the module's mechanical service life. The bifacial HJT cell architecture — with a typical bifaciality factor of ~80–85% for HJT — realistically increases energy yield by 5–15% in ground-mounted systems and flat-roof installations with high-albedo surfaces. - **Bankable Tier-1 manufacturer with certified financial credibility** - Heliene appears on established bankable Tier-1 manufacturer lists, a key requirement for securing financing of commercial projects and utility-scale PV farms through independent commercial banks. This status confirms the manufacturer's ability to fulfill long-term warranty obligations, reducing financial risk for institutional investors. - **Half-cut G12 cells — reduced shading losses** - The 132 half-cut cell layout in G12 format (210 mm) divides the module into two independent electrical halves, limiting the impact of partial shading on overall energy yield. Combined with HJT characteristics (no LID, minimal LETID), first-year and early-life degradation is significantly lower than in PERC modules. ## Cons - **15-year product warranty — below premium tier** - In the utility-class HJT glass-glass segment, some competitors offer product warranties of 20–25 years (e.g., REC Alpha, Panasonic HIT). A 15-year product warranty may be a limiting factor for projects structured under PPA or BOOT agreements with terms exceeding this threshold, where full product coverage throughout the entire financing period is required. - **Limited service network in Central and Eastern Europe** - Heliene is a Canada-based manufacturer founded in 2010, with its primary target market in North America. Compared to Chinese Tier-1 giants such as LONGi, Jinko, and Trina — which maintain a local presence in Poland and the broader CEE region — lead times for potential warranty claims and the availability of on-site technical support may be longer. This is a relevant consideration for large-scale PV farms with SLA requirements. ## About this series The Heliene 132HC G12 HJT SL Bifacial series has been designed for maximum energy yield in situations where every square meter and long-term stability are crucial. The use of **N-type cells in the HJT technology** results in high efficiency under variable conditions and excellent resistance to typical power losses, which reduces the profitability of installations. These are **bifacial** modules - they can also utilize light from the rear, thereby realistically increasing production on reflective surfaces, flat roofs, and ground-mounted systems. The **glass-glass** construction improves durability and parameter stability over the long term, which will be appreciated by investors focused on predictable returns. Furthermore, the **half-cut** design supports better performance under partial shading and reduces losses within the module. This solution is particularly suitable for PV farms, large commercial roofs, and projects where a lower BOS (Balance of System) cost and better energy yield from the same area are important. ## Notable figures - At 22.2% efficiency, this panel is on par with typical \*\*HJT 650-700W\*\* modules - At 222.1 W/m² power density, roof space requirements are typical for \*\*HJT 650-700W\*\* panels - -0.26%/°C temperature coefficient - 0.02pp worse than \*\*HJT 650-700W\*\* median (-0.24%/°C), expect higher hot weather losses - Bifacial design (85% factor) captures reflected light - adds 4-13% yield on ground-mount or white roof - In the top 41% for efficiency among all HJT panels ## Questions ### What is the power output and efficiency of the Heliene 132HC G12 HJT SL Bifacial? The Heliene 132HC G12 HJT SL Bifacial series reaches a maximum power of 710 Wp with module efficiency around 22.9%. This is among the highest figures in the utility-scale panel class, made possible by N-type HJT cells and the G12 wafer format. In practice, it delivers more energy from the same roof or ground area compared to standard PERC modules. ### What is HJT technology and why does it matter for the Heliene 132HC G12 series? HJT (Heterojunction Technology) combines monocrystalline silicon cells with thin amorphous silicon layers, resulting in a low temperature coefficient of around -0.24%/°C. This means the module loses far less power on hot days than typical PERC cells. N-type HJT cells are also resistant to LID degradation, ensuring more stable power output over the full system lifetime. ### What warranty does the Heliene 132HC G12 HJT SL Bifacial come with? Heliene provides a 15-year product warranty covering material and manufacturing defects, and a 25-year linear power warranty guaranteeing at least 90% of rated output at end of term. As a Tier 1 manufacturer, Heliene backs these commitments with established financial standing and global service capability. ### Is the Heliene 132HC G12 HJT SL Bifacial suitable for large ground-mount and utility-scale PV projects? Yes, this module is designed primarily for utility-scale and large commercial rooftop installations. The G12 format, 710 Wp power class, and glass-glass construction reduce BoS costs by minimizing the number of modules, cables, and mounting structures per MW. Bifaciality further boosts energy yield in ground-mount systems with reflective surfaces beneath the array. ### How does bifacial design affect the real-world energy production of the Heliene 132HC G12 HJT SL Bifacial? Bifacial modules capture reflected and diffuse light reaching the rear side of the panel. Typical bifacial gain ranges from 5% to 15% depending on ground albedo, tilt angle, and mounting height. Best results occur over light-colored gravel, white roofing membranes, or snow. The glass-glass construction protects the rear glass and sustains this advantage throughout the module's service life. ### Is the Heliene 132HC G12 HJT SL Bifacial series still available for purchase? Yes, the series is active and available. Heliene is a Tier 1 Canadian manufacturer with production facilities in North America and Europe. For large-scale orders such as utility farms or commercial projects, it is advisable to confirm lead times with your distributor, as delivery schedules can vary based on project volume and region. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HSPE-132HC-G12-HJT-SL-Bifacial-Rev00-1dd0dad1a17c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Lighter, +3.0 pp, +5 yr warranty | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Lighter, +3.0 pp, +5 yr warranty | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Lighter, +2.8 pp, +5 yr warranty | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Lighter, +2.8 pp, +5 yr warranty | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Lighter, +2.8 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Lighter, +2.7 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Lighter, +2.6 pp, +5 yr warranty | | [Heliene 132HC-695 G12 HJT Bifacial Module](https://comparepv.com/panel/heliene-132hc-695-g12-hjt-bifacial-module) | 695 W | Very close match | | [Heliene 132HC-700 G12 HJT Bifacial Module](https://comparepv.com/panel/heliene-132hc-700-g12-hjt-bifacial-module) | 700 W | +10 W, +0.3 pp | | [Heliene 132HC-705 G12 HJT Bifacial Module](https://comparepv.com/panel/heliene-132hc-705-g12-hjt-bifacial-module) | 705 W | +15 W, +0.5 pp | | [Heliene 132HC-710 G12 HJT Bifacial Module](https://comparepv.com/panel/heliene-132hc-710-g12-hjt-bifacial-module) | 710 W | +20 W, +0.6 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +115 W, +2.9 pp, +5 yr warranty | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +110 W, +2.7 pp, +5 yr warranty | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +105 W, +2.6 pp, +5 yr warranty | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +100 W, +2.4 pp, +5 yr warranty | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +70 W, +2.3 pp, +5 yr warranty | --- Source: https://comparepv.com/panel/heliene-132hc-690-g12-hjt-bifacial-module 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.
