Light for its output, weak in heat
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.

Signals from the data
Commercial, utility-scale and shaded-installations.
Hot climates, roofs where every square metre has to count and tight roof space.
Top 11% of the HJT 650-700 W segment, against a median of 55.7.
Bottom 4% of the HJT 650-700 W segment, against a median of -0.240. Ranked 12,345th in the whole database.
Bottom 7% of the HJT 650-700 W segment, against a median of 222.1. Ranked 8,959th in the whole database.
Bottom 7% of the HJT 650-700 W segment, against a median of 22.20%. Ranked 8,250th in the whole database.
Peak efficiency of 21.78% exceeds directly comparable modules: Hiwatt Solar HW-M12/132H (21.6%), Techwise Summit Series (21.57%), and Resun RS9H-M (21.57%). That's a real advantage per unit of installed area.
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.
Fewer modules per project mean simpler cabling, faster installation, and lower BoS costs — relevant for utility-scale PV and large rooftop installations.
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.
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.
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.
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.
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.
- At 21.5% efficiency, this panel is 0.7pp below the HJT 650-700W median of 22.2%
- 212.5 W/m² power density is 9.6 W/m² below HJT 650-700W median (222.1 W/m²) - requires larger installation area
- -0.36%/°C temperature coefficient - 0.12pp worse than HJT 650-700W median (-0.24%/°C), expect higher hot weather losses
- 34.0 kg weight - 4.5 kg lighter than HJT 650-700W median (38.5 kg), reducing installation effort
- Bifacial design (75% factor) captures reflected light - adds 4-11% yield on ground-mount or white roof
