That's a real advantage per unit of installed area. - **HJT + bifacial + half-cut + white mesh** - Combining HJT cells with a half-cut layout and a bifacial white mesh backsheet delivers low LID/LeTID degradation, extra rear-side gain from reflected light, and better performance under diffuse irradiance than mono-facial PERC designs. - **High unit power 650-670 Wp** - Fewer modules per project mean simpler cabling, faster installation, and lower BoS costs — relevant for utility-scale PV and large rooftop installations. - **Lightweight glass-foil construction** - Unlike the heavier glass-glass variant in the same series (e.g. HJT GG BiF M132 680-700W), the glass-foil build reduces module mass, easing installation on roofs with limited load capacity. - **Established manufacturer track record** - Luxor Solar has operated since 2007, headquartered in Germany, and the ECO LINE M132 series has been on the market since 2022 without discontinuation, ensuring supply and service continuity. ## Cons - **No Tier-1 (BNEF) status** - Luxor Solar is not listed on the current BNEF Tier-1 manufacturer list, which can complicate non-recourse bank financing for large-scale PV projects compared to Tier-1 peers. - **Warranty below HJT's potential** - A 15-year product warranty and 25-year power warranty reflect an older industry standard — thanks to low annual degradation, HJT technology now lets many manufacturers offer 25-30 year product warranties and 30-year linear power warranties. - **White mesh instead of glass-glass** - A white mesh backsheet typically yields a lower bifaciality factor than the glass-glass construction used in other HJT variants of the same series (e.g. LX\_EL\_HJT\_GG\_HC\_BiF M132 680-700W), potentially limiting extra rear-side yield. ## About this series The Luxor Solar ECO LINE Half Cell Bifacial (White mesh) M132 650-670 W series is designed as a high-power module for installations where maximizing energy yield from each structural section is crucial. It combines **bifacial technology** with **half-cell architecture**, allowing it to effectively generate power not only from the front, but also by utilizing reflected light from the ground - which significantly improves production in PV farms, industrial rooftops, and ground-mounted systems. The distinctive **White mesh** on the back side enhances the utilization of diffuse radiation and facilitates stable operation in varying lighting conditions. It is also a series for investors who want to reduce costs related to equipment and installation - the high power of a single module means fewer units are needed for the same project, resulting in simpler wiring and faster logistics. The ECO LINE M132 also features a **glass-foil construction**, which helps reduce the module's weight without compromising its durability, which is important for large-scale projects and rooftop installations. ## Notable figures - Efficiency of 21.8% matches the \*\*HJT 650-700W\*\* median - Power density of 215.7 W/m² is 6.4 W/m² below \*\*HJT 650-700W\*\* median (222.1 W/m²) - needs more roof space - -0.36%/°C temperature coefficient - 0.12pp worse than \*\*HJT 650-700W\*\* median (-0.24%/°C), expect higher hot weather losses - Weight of 34.0 kg (4.5 kg below \*\*HJT 650-700W\*\* median of 38.5 kg) allows easier transport and roof mounting - Bifacial design (75% factor) captures reflected light - adds 4-11% yield on ground-mount or white roof ## Questions ### What warranty does the Luxor Solar ECO LINE Half Cell Bifacial M132 650–670 W carry? The manufacturer provides a 15-year product warranty and a 25-year linear power output warranty. For a full quarter-century, Luxor Solar guarantees a defined minimum power output per module. With headquarters in Germany, the company designs its modules to European quality standards, ensuring predictable long-term system performance for both residential and commercial owners. ### What is HJT cell technology in the Luxor Solar ECO LINE M132, and is the premium worth it? HJT (Heterojunction Technology) combines a monocrystalline silicon wafer with an amorphous silicon thin film, achieving higher efficiency than conventional PERC cells and a lower temperature coefficient. In the ECO LINE M132 series this translates to up to 670 Wp per module and reduced power losses on hot summer days — a meaningful advantage for large commercial installations and utility-scale PV farms. ### How does bifacial technology work in the Luxor Solar ECO LINE M132, and how much additional energy yield can I expect? Bifacial modules harvest irradiation from both the front and the rear side of the cells. The White mesh backsheet of the ECO LINE M132 series enhances absorption of reflected and diffuse light (albedo gain). In practice, ground-mount systems or installations over high-albedo surfaces such as gravel or light-colored roofing membrane can achieve 5–15% higher annual energy yield compared to a monofacial module. ### Are the Luxor Solar ECO LINE M132 670 W panels suited for large industrial rooftops and ground-mount systems? Yes — the ECO LINE M132 series is engineered for high-power applications: utility-scale PV farms, warehouse rooftops, and ground-mount systems. At up to 670 Wp per module, fewer panels are required for the same target output, reducing string count, cabling complexity, and installation time. The glass-foil construction keeps module weight around 34 kg while maintaining a snow load rating of 5400 Pa and wind load of 2400 Pa. ### How does the White mesh backsheet on the ECO LINE M132 differ from a standard white backsheet? A conventional white backsheet on a bifacial module blocks light transmission entirely. White mesh is a perforated rear layer that allows a portion of reflected irradiation to reach the rear cells while still providing mechanical protection and electrical insulation. This enables the ECO LINE M132 series to better capture diffuse irradiation, especially under partially overcast skies or in systems installed over high-albedo ground surfaces. ### Is Luxor Solar a reliable manufacturer? The brand is not Tier 1 — should that be a concern? Luxor Solar is a German-headquartered company with a long track record in the European PV market. Bloomberg NEF's Tier 1 classification is based on financial criteria related to module securitization, not product quality directly. Luxor Solar modules comply with IEC standards and are sold through certified distributors across Europe. For commercial or project-financed installations, it is advisable to confirm that the project insurer or lender accepts modules from manufacturers outside the Tier 1 list. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/lx-el-hc-bif-sw-m132-650-670w-210-en-4d4fbba7a12d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, +3.2 pp, +5 yr warranty | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, +3.1 pp, +5 yr warranty | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +3.0 pp | | [Luxor Solar LX-650M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-650m-210-132-bif) | 650 W | -20 W, -0.7 pp | | [Luxor Solar LX-655M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-655m-210-132-bif) | 655 W | -15 W, -0.5 pp | | [Luxor Solar LX-660M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-660m-210-132-bif) | 660 W | -10 W, -0.3 pp | | [Luxor Solar LX-665M/210-132+BiF](https://comparepv.com/panel/luxor-solar-lx-665m-210-132-bif) | 665 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +135 W, cooler, +3.3 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +130 W, cooler, +3.1 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +125 W, cooler, +3.0 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +120 W, cooler, +2.8 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +90 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/luxor-solar-lx-670m-210-132-bif Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
