A 0.2-0.4 pp advantage translates into meaningfully higher energy yield from the same roof or ground area. - **Dual technology: bifacial + half-cut** - Combining bifacial cells with half-cut technology reduces resistive losses and improves performance under partial shading, while also capturing reflected light from the ground surface. This is particularly effective on bright roof surfaces and ground-mount installations. - **Large-format M132 210mm cells** - The use of large M132 cells in a module measuring 2384 x 1303 mm and weighing only 34 kg delivers high power density (up to 670 Wp per module), lowering mounting structure, cabling, and installation labor costs per kWp. - **High-durability glass-glass construction** - The glass-glass design provides resistance to snow loads up to 5400 Pa and wind loads up to 2400 Pa, offering better mechanical durability than typical glass-backsheet modules - important for installations in demanding climate conditions. - **German manufacturer with 19-year history** - Luxor Solar is headquartered in Germany, founded in 2007, with an established presence in the European market and a reportedly low complaint rate, providing some quality assurance despite lacking Tier-1 status. ## Cons - **Series discontinued** - The ECO LINE HALF CELL BIFACIAL M132 series has been discontinued. This means limited availability for expanding existing installations and potential difficulties with warranty service and replacement parts going forward. - **Manufacturer outside BNEF Tier-1 list** - Luxor Solar is not listed as a Tier-1 manufacturer under BNEF methodology (classified as Tier-2), which can complicate bank financing for large commercial projects and PV farms, where Tier-1 status is often a formal lender requirement. - **Shorter product warranty than market standard** - The 15-year product warranty falls below the current premium-segment standard, where leading manufacturers (e.g., Trina, JA Solar, LONGi) offer 25-30 years of product warranty. The 25-year power warranty is likewise shorter than the 30-year linear warranties offered by some Tier-1 competitors. ## About this series The Luxor Solar ECO LINE HALF CELL BIFACIAL M132 photovoltaic panel series, with power ranging from 650 to 670 W, is an advanced solution designed to maximize yields from large installation areas. The foundation of this technology is **double-sided bifacial cells**, which allow for energy harvesting not only from direct sunlight but also from light reflected off the ground. This approach significantly increases system efficiency in difficult ground conditions or on light-colored roof surfaces. Thanks to the use of **Half-Cell technology**, these modules are characterized by reduced resistive losses and significantly better performance in partial shading conditions, which directly translates into the stability of energy production over a long period. The M132 series stands out for its use of large-format cells, which enables **extremely high power density** while optimizing mounting structure and cabling costs. It is a product primarily dedicated to professional investors developing solar farms and large-scale commercial facilities, where the **lowest Levelized Cost of Energy (LCOE)** is of key importance. Compared to traditional solutions, the ECO LINE M132 series offers higher mechanical resistance and a more favorable temperature coefficient, making it an extremely cost-effective choice in the industrial segment. ## Notable figures - Efficiency of 21.8% matches the \*\*database\*\* median - At 215.7 W/m² power density, roof space requirements are typical for \*\*database\*\* panels - At -0.36%/°C, loses 0.06pp more power per degree than \*\*database\*\* median (-0.30%/°C) - Weight of 34.0 kg is 7.5 kg above \*\*database\*\* median (26.5 kg) - verify structural support - 75% bifaciality enables rear-side power generation, boosting yield by 4-11% on reflective surfaces ## Questions ### Is the Luxor Solar ECO LINE HALF CELL BIFACIAL M132 650-670 W series still available for purchase? The M132 650-670 W series has been discontinued and is no longer offered as a new product by Luxor Solar. Remaining stock may still be available through some distributors, but supply is limited. For new projects, it is advisable to consider currently manufactured Luxor Solar series that offer comparable or higher power output and come with full manufacturer warranty support. ### What does bifacial technology mean in the Luxor ECO LINE M132 modules, and does it actually improve energy yield? Bifacial technology means the cells generate electricity from both sides of the module - from direct sunlight on the front and from light reflected off the ground onto the rear. The M132 series uses a glass-glass construction that allows effective use of reflected irradiance. On light-colored surfaces such as gravel, concrete, or snow, energy yield can increase by 5-15% compared to standard monofacial modules, directly reducing the overall LCOE of the installation. ### What warranty does Luxor Solar offer on the ECO LINE HALF CELL BIFACIAL M132 modules? Luxor Solar provides a 15-year product warranty covering material and manufacturing defects, along with a 25-year linear power output warranty. In practice, this means the module is guaranteed to retain a specified minimum percentage of its rated power over 25 years, with detailed degradation thresholds outlined in the warranty document. The original purchase invoice and installation records should be kept, as they are required for any warranty claim. ### What type of installations are the Luxor Solar M132 650-670 W panels best suited for, and are they a good fit for a residential rooftop? The M132 series is engineered primarily for utility-scale solar farms and large commercial facilities. Each module weighs 34 kg and measures 2384 × 1303 mm, making rooftop handling difficult and requiring a reinforced mounting structure. For residential rooftop installations, smaller and lighter modules from the residential segment are a significantly better fit. The M132 series is the right choice for professional investors focused on minimizing LCOE across large arrays. ### How does half-cut cell technology affect the performance of Luxor M132 modules under partial shading? Half-cut cells split each cell into two smaller halves, reducing the operating current by half and lowering resistive losses proportionally to the square of the current. As a result, partial shading of one section of the module has a smaller impact on the output of the remaining sections compared to conventional full-cell modules. The M132 series incorporates 132 half-cut cells, delivering noticeably more stable energy production under non-uniform irradiance conditions, such as shadows cast by distant obstructions. ### What mechanical loads can the Luxor ECO LINE BIFACIAL M132 panels withstand, and are they suitable for regions with heavy snowfall? According to manufacturer data, the M132 series modules are rated for snow loads up to 5400 Pa and wind loads up to 2400 Pa. The glass-glass construction adds rigidity and mechanical strength compared to standard backsheet modules. This means that with a properly designed and installed mounting system, the panels should handle conditions typical of Central European climates, including accumulated snow. A structural engineering review of the racking system by a qualified designer is always recommended. ## 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 | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 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 | --- Source: https://comparepv.com/panel/luxor-solar-lx-670m-210-132-bif-1 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.
