Efficiency leader, weak in heat
The Luxor Solar ECO LINE HJT GLASS-GLASS BIFACIAL (M132 / 680-700 W, White Mesh) series is designed to maximize energy yield from each module, even under less-than-ideal conditions on the roof or ground. The use of N-type HJT (heterojunction) cells results in very low energy losses over time and stable energy production across a wide range of temperatures, which significantly improves the return on investment. The glass-glass construction provides higher stiffness and resistance to mechanical loads, as well as better thermal stability, leading to longer, trouble-free operation. Thanks to bifaciality, the module can also utilize reflected light from the ground, increasing energy yield without increasing the installation area. The characteristic White Mesh design facilitates aesthetically pleasing installations in projects where appearance and uniform visual reception are important. This solution is particularly suitable for PV farms, industrial installations, large commercial rooftops, and carport structures, where its advantages include durability, increased energy yield, and reduced BOS (balance of system) costs due to the higher power of the modules.
Ranking
Signals from the data
Commercial and utility-scale.
Hot climates.
Top 3% of the HJT 650-700 W segment, against a median of 22.20%. Ranked 3,887th in the whole database.
Top 16% of the HJT 650-700 W segment, against a median of 222.1.
Bottom 24% of the HJT 650-700 W segment, against a median of -0.240.
Heterojunction (HJT) technology typically offers a low temperature coefficient of around -0.24%/°C (versus -0.35% to -0.41%/°C for conventional PERC cells) and minimal LID/LeTID degradation, resulting in higher energy yield on hot days and more stable performance over the module's lifetime.
The manufacturer offers 30 years of product warranty alongside 30 years of power warranty - longer than the standard 12-15 year product / 25-30 year power warranties offered by most peer comparables (Mysolar USA, Sunket, VSUN), increasing long-term investment security.
Dual-glass construction instead of a rear polymer backsheet improves mechanical rigidity, PID resistance, and thermal stability, reducing microcracking and accelerated degradation typical of glass-backsheet designs, especially under heavy snow or wind loads.
Module efficiency in the 22.1-22.74% range matches or exceeds comparable N-type models in the 680-700 Wp segment (Mysolar 22.53%, Sunket 22.5%, VSUN 22.53%), delivering higher installed power per roof area and lower BoS costs.
The symmetrical structure of HJT cells enables effective use of ground-reflected light on the rear side of the module, particularly valuable for ground-mount installations, carports, and large industrial roofs with light-colored surfaces.
Luxor Solar does not appear on the BNEF Tier 1 list (as of Q1/Q2 2026, dominated by Jinko, LONGi, Trina, JA Solar, Tongwei), which despite the German headquarters and 30-year warranty may complicate bank financing for large commercial projects requiring formal manufacturer bankability.
The white mesh rear backing, while improving aesthetics and visual uniformity, typically transmits less light than a fully transparent glass-glass construction, which may reduce the actual additional rear-side yield compared to fully transparent variants.
- At 22.6% efficiency, this panel is on par with typical HJT 650-700W modules
- Power density of 223.7 W/m² matches the HJT 650-700W median
- Temperature coefficient of -0.26%/°C is 0.02pp worse than HJT 650-700W median (-0.24%/°C) - higher losses in summer heat
- Bifaciality factor of 83% can add 4-12% extra yield with reflective mounting surface
- In the top 28% for efficiency among all HJT panels
